Append-only chronological record. Each entry starts with ## [YYYY-MM-DD] <type> | <title> so it stays greppable, e.g. grep "^## \[" wiki/log.md | tail -5.

[2026-08-18] setup | Wiki scaffold created

• Created vault structure (raw/, wiki/sources, wiki/conditions, wiki/procedures, wiki/concepts, wiki/guidelines-trials), CLAUDE.md schema, and index/overview/log pages.
• Ready for first source ingest.

[2026-08-18] ingest | Azhar 2021 - SCANDIV 5-Year Outcomes

• Filed source page for the SCANDIV trial's 5-year long-term follow-up (JAMA Surg 2021): laparoscopic lavage vs. primary resection for perforated purulent diverticulitis.
• Created SCANDIV Trial (guidelines-trials) to track this landmark RCT across its publications (90-day/1-year reports not yet ingested).
• Created Diverticulitis (first condition page) — Hinchey classification folded in per Stephen's request, plus the lavage-vs-resection synthesis and diverging ASCRS/ESCP guideline positions.
• Updated index.md and the sources/conditions/guidelines-trials landing pages.

[2026-08-18] ingest | Vennix 2015 - Ladies Trial LOLA

• Filed source page for the Ladies trial (LOLA group), Lancet 2015 — lavage vs. sigmoidectomy for perforated purulent diverticulitis, stopped early for safety.
• Created Ladies Trial (LOLA) guidelines-trials page.
• Updated SCANDIV Trial with a cross-trial comparison section: recurrence signal replicates closely between SCANDIV and Ladies, but short-term morbidity/reintervention signal is starker in Ladies (trial-stopping) than in SCANDIV's 5-year report — flagged as an open question.
• Updated Diverticulitis with the same cross-trial synthesis, plus a note that Hinchey III/IV distinction is unreliable pre/intraoperatively in both trials.
• Updated index.md and the sources/guidelines-trials landing pages.

[2026-08-18] ingest | Boublikova 2023 - TNT in Rectal Cancer Review

• First rectal cancer / oncology source (prior sources were diverticulitis surgery). Filed as a narrative review synthesizing 4 phase III TNT trials (POLISH II, RAPIDO, PRODIGE 23, STELLAR).
• Created Total Neoadjuvant Therapy (TNT) concept page — efficacy/trade-offs (incl. RAPIDO's locoregional recurrence signal), risk-stratified indications, RT/chemo/immunotherapy regimens, sequencing, non-operative management, adjuvant therapy, and the review's risk-based algorithm.
• Created Rectal Cancer as a stub condition page (staging/anatomy/procedures not yet covered) to anchor future rectal cancer sources.
• Updated index.md and the sources/conditions/concepts landing pages.

[2026-08-19] ingest | Hoehn 2021 - Appendiceal Neoplasms

• Filed source page for this ASCO Educational Book review covering all 5 histopathologic subtypes of appendiceal neoplasms (MAN/PMP, NEN, GCA, colonic-type adenocarcinoma, signet ring adenocarcinoma).
• Created Appendiceal Neoplasms condition page — AJCC 8th ed. + PSOGI staging, management by subtype, cross-cutting notes (right hemicolectomy indications, metastatic workup).
• Created Cytoreductive Surgery and HIPEC concept page — PCI/CC scoring, appendiceal PMP outcomes, and the CRS/HIPEC controversies (PRODIGE 7, COLOPEC, PCI cutoff debate, agent choice).
• Updated index.md and the sources/conditions/concepts landing pages.

[2026-08-19] ingest | Lambrichts 2019 - LADIES DIVA Trial

• Filed source page for the LADIES trial's DIVA arm: Hartmann's procedure vs. primary anastomosis for Hinchey III/IV perforated diverticulitis. Primary anastomosis strongly favored (stoma-free survival 94.6% vs 71.7%, HR 2.79, p<0.0001) — one of the more decisive findings in the wiki so far, and the first source covering Hinchey IV (fecal peritonitis).
• Expanded Ladies Trial (LOLA) into a unified Ladies Trial page covering both LOLA and DIVA arms (added aliases: ["Ladies Trial", "LADIES Trial"] to frontmatter so existing backlinks still resolve under the old filename).
• Added a "Hartmann's procedure vs. primary anastomosis" section to Diverticulitis.
• Updated index.md, sources/guidelines-trials landing pages.

[2026-08-19] ingest | Sabiston Ch52 - Diverticular Disease, Obstruction & Pseudo-Obstruction

• First chunk of the large (82-page) Sabiston "Colon and Rectum" textbook chapter, filed as a reference source (not primary literature) per Stephen's instruction. Chapter is being split into topic chunks across multiple ingests (this one: diverticular disease completion, large bowel obstruction, Ogilvie syndrome; still to come: IBD, neoplasia/rectal cancer surgery, pelvic floor).
• Expanded Diverticulitis — closed two previously flagged open items: uncomplicated diverticulitis management (antibiotics controversy, colonoscopy timing, recurrence) and elective surgery timing (shifted from "number of attacks" to individualized assessment). Added a special populations section (right-sided, immunocompromised, young patients — the last of which overturns older "operate after one attack under 50" teaching).
• Created Large Bowel Obstruction and Colonic Pseudo-Obstruction (Ogilvie Syndrome) as new condition pages — general surgical topics within a colorectal surgeon's scope, not previously covered.
• Copied the full chapter PDF to raw/ as Sabiston Ch52 - Colon and Rectum.pdf; later chunks will cite specific page ranges within the same file.
• Updated index.md, conditions/sources landing pages.

[2026-08-19] ingest | Sabiston Ch52 - Inflammatory Bowel Disease

• Second chunk of the Sabiston "Colon and Rectum" chapter, filed as a reference source (not primary literature). Covers the full IBD section — the wiki's first content on UC/Crohn's.
• Created Inflammatory Bowel Disease (shared epidemiology/classification/clinical features/ diagnosis/medical treatment), Ulcerative Colitis and Crohn Disease (disease-specific surgical indications and options) as three separate condition pages given the volume of surgeon-relevant detail.
• Created Ileal Pouch-Anal Anastomosis (IPAA) — the wiki's first procedure page — covering J-pouch construction, stapled vs. hand-sewn technique, tension-reducing maneuvers, complications, and functional outcomes. Referenced by both the UC and Crohn's pages.
• Flagged that none of this chunk's content is backed by primary trial/cohort data yet — it's a textbook skeleton (classification schemes, drug tables, indications-for-surgery framework) pending future primary-literature ingests (biologic trials, pouchitis outcomes, UC surveillance literature).
• Updated index.md, conditions/procedures/sources landing pages (Procedures.md gets its first real entry).

[2026-08-19] ingest | Sabiston Ch52 - Infectious & Ischemic Colitis

• Third chunk of the Sabiston "Colon and Rectum" chapter, filed as a reference source (not primary literature). Covers Infectious Colitis (C. difficile in depth, plus other enteric pathogens) and Ischemic Colitis.
• Created Infectious Colitis — C. diff epidemiology/risk factors/severity scoring/diagnosis/ treatment ladder (vancomycin/fidaxomicin over metronidazole)/FMT/monoclonal antibodies/surgical indications, plus a table of other enteric pathogens (Campylobacter, Yersinia, Shigella, Salmonella, CMV). Corrected a source error (chapter's table lists Campylobacter as gram-positive; it's gram-negative) rather than propagating it.
• Created Ischemic Colitis — watershed anatomy (Griffiths point, Sudeck's point, right colon vulnerability), risk factors, diagnosis (endoscopy as gold standard, single-stripe sign, CT findings), treatment (conservative succeeds in ~80%), and surgical technique (ICG angiography for viability assessment, damage-control/second-look approach, no indication for revascularization unlike small-bowel mesenteric ischemia).
• Updated index.md, conditions/sources landing pages.

[2026-08-19] ingest | Sabiston Ch52 - Colorectal Neoplasia & Colon Cancer Surgery

• Fourth (and largest so far) chunk of the Sabiston "Colon and Rectum" chapter, filed as a reference source (not primary literature). Covers CRC molecular genetics, polyps, all five hereditary CRC syndromes, TNM staging, and colon cancer surgical technique/obstructing colon cancer — everything up to where "Rectal Cancer" begins in the chapter (next chunk).
• Created Colorectal Cancer Molecular Pathways (chromosomal instability, CIMP, MSI mutator pathway, EMT, CMS1-4) and Colorectal Cancer Staging (TNM) as new concept pages.
• Created Colorectal Polyps (nonneoplastic/serrated/neoplastic, Haggitt/Kikuchi classification, postpolypectomy surveillance) and Obstructing Colon Cancer as new condition pages.
• Created Hereditary Colorectal Cancer Syndromes as an overview/comparison page, with three detail pages: Familial Adenomatous Polyposis (FAP) (including MUTYH-associated polyposis), Lynch Syndrome, and Hamartomatous Polyposis Syndromes (Peutz-Jeghers + juvenile polyposis). Flagged that the Lynch syndrome extended-vs-limited-colectomy question has no prospective RCT per the source itself — a good target for a future primary-literature ingest.
• Created Colon Cancer Resection as a new procedure page — general oncologic principles plus technique by tumor location (right, transverse, splenic flexure, left).
• Updated index.md, conditions/concepts/procedures/sources landing pages.

[2026-08-19] ingest | Sabiston Ch52 - Rectal Cancer Surgery

• Fifth chunk of the Sabiston "Colon and Rectum" chapter, filed as a reference source (not primary literature). Covers rectal cancer preoperative evaluation/staging through TME history, LAR, sphincter-sparing surgery, taTME, APR, anastomotic complications, LARS, and adjuvant chemotherapy by stage. One chunk (pelvic floor disorders) remains in this chapter.
• Substantially expanded the previously-stub Rectal Cancer page: preoperative evaluation, ERUS/MRI staging, the TME/CRM/downstaging history (German Rectal Cancer Study, Heald, Quirke, Habr-Gama watch-and-wait), survival by stage, surveillance schedule, and adjuvant chemotherapy by stage (including the IDEA duration-trial risk stratification and the metastatic-disease regimen-selection framework by RAS/BRAF status and tumor sidedness). This page now sits properly alongside the existing Total Neoadjuvant Therapy (TNT) concept page instead of being a TNT-only placeholder.
• Created three new procedure pages: Local Excision of Rectal Neoplasms, Total Mesorectal Excision (TME) & Sphincter-Sparing Resection (LAR + coloanal anastomosis + taTME grouped together), and Abdominoperineal Resection (APR).
• Created Colorectal Anastomotic Complications as a new concept page (leak, necrosis, bleeding, twisting, strictures — cross-cutting, not rectal-specific) and Low Anterior Resection Syndrome (LARS) as a new condition page.
• Updated index.md, conditions/concepts/procedures/sources landing pages.

[2026-08-19] ingest | Sabiston Ch52 - Pelvic Floor Disorders & Constipation

• Sixth and final chunk of the Sabiston "Colon and Rectum" chapter (Colon.pdf) — all 82 pages now ingested across 6 chunks, filed as reference sources (not primary literature) per Stephen's original instruction. Covers anorectal physiology testing/imaging, rectal prolapse, solitary rectal ulcer syndrome, rectocele, and constipation.
• Created Anorectal Physiology Testing as a new concept page — manometry, balloon expulsion, pudendal nerve terminal motor latency, EMG, endoanal ultrasound, defecography, colonic transit study — the shared diagnostic toolkit for all the pelvic floor condition pages below.
• Created Rectal Prolapse (Procidentia) (condition) and Rectal Prolapse Repair (procedure, abdominal mesh rectopexy vs. perineal Altemeier/Delorme/STARR approaches, including the note that ASCRS guidelines do not recommend STARR given its complication profile).
• Created Solitary Rectal Ulcer Syndrome (SRUS), Rectocele, and Constipation (Rome IV criteria, slow transit constipation, TAC-IRA/CIRA surgical options) as new condition pages.
• Updated index.md, conditions/concepts/procedures/sources landing pages.
• With this chunk complete, only the Sabiston "Small Bowel" chapter (61 pages) remains as the last planned source for this wiki's initial ingest pass.

[2026-08-19] ingest | Sabiston Ch50 - Small Bowel Anatomy, Physiology, Obstruction & Crohn Disease

• First chunk (of an expected 3) of the Sabiston "Small Bowel" chapter (Chapter 50, "Small Intestine," authors Tong Gan & B. Mark Evers) — the final source in the original ingest list. Filed as a reference source (not primary literature), following the same discuss-first, chunked workflow used for the Colon and Rectum chapter, per Stephen's blanket approval to proceed through the rest of this source without stopping to ask each time.
• Created Small Intestine Anatomy & Physiology as a new concept page — embryology; gross, neurovascular/lymphatic, and microscopic anatomy; digestion/absorption physiology (carbs, protein, fat, water/electrolytes/vitamins); motility (MMC); endocrine function (GI hormones/ receptors); immune function (GALT, Peyer patches, IgA).
• Created Small Bowel Obstruction as a new condition page, distinct from the existing Large Bowel Obstruction page — causes (adhesions ~60%, neoplasms, hernias, Crohn's, misc), pathophysiology, simple vs. strangulating obstruction, diagnosis (imaging accuracy), treatment ladder, and management of specific problems (recurrent obstruction/adhesion prevention, acute postoperative obstruction, ileus as a differential).
• Substantially expanded the existing Crohn Disease page (previously a colon-surgery-only stub from Sabiston Ch52 - Inflammatory Bowel Disease) with a full small-bowel-focused treatment: history, epidemiology, etiology (including the NOD2/CARD15 genetics table), gross/microscopic pathology, Montreal classification, clinical manifestations, diagnosis (serology, fecal markers, CTE/MRE, endoscopy including capsule endoscopy, CDAI), the complete medical therapy ladder, and small-bowel-specific surgical treatment (primary anastomosis vs. diversion, anastomotic technique including Kono-S, laparoscopic approach, and specific problems: acute ileitis, stricturing disease/ strictureplasty, bypass procedures, penetrating disease, perforation). Prior colonic-surgery content preserved and merged in rather than overwritten.
• Updated index.md, conditions/concepts/sources landing pages.
• Next: remaining Inflammatory and Infectious Diseases (typhoid, immunocompromised enteritis), Neoplasms, Diverticular Disease, and Miscellaneous Problems sections of this chapter (pages 31–61).

[2026-08-19] ingest | Sabiston Ch50 - Infectious Enteritis & Small Bowel Neoplasms

• Second chunk of the Sabiston "Small Bowel" chapter, continuing without per-chunk approval pauses per Stephen's instruction to proceed through the rest of this source using the established methods.
• Merged the remainder of the Crohn Disease section into the existing Crohn Disease page: colorectal disease surgical principle, perianal disease (fistulotomy/setons/infliximab/diverting stoma/proctectomy), duodenal disease, GI bleeding, urologic complications, and a new Prognosis section including the postoperative surveillance algorithm (Fig. 50.25, risk-stratified anti-TNF/AZT-6MP vs. metronidazole with surveillance endoscopy).
• Created Typhoid Enteritis and Enteritis in the Immunocompromised Host as new condition pages — the latter covering protozoal (Cryptosporidium, Isospora, Microsporidium), bacterial, mycobacterial (MAC, TB), viral (CMV), and fungal enteric pathogens in AIDS/transplant patients.
• Created Small Bowel Neoplasms as a new overview condition page (epidemiology, risk factors, molecular genetics, clinical manifestations, diagnosis, benign tumors, and lymphoma), plus three dedicated pages for the largest malignant subtypes: Small Bowel Neuroendocrine Tumors (NETs) (carcinoid syndrome, CgA/5-HIAA/DOTATATE diagnosis, SSA/everolimus/PRRT treatment), Small Bowel Adenocarcinoma (surgical treatment by location, adjuvant chemotherapy, prognosis), and Gastrointestinal Stromal Tumors (GIST) (KIT/CD117, mitotic index risk stratification, imatinib-based treatment algorithm) — mirroring the multi-page split used for the colon cancer chunk of the Colon and Rectum chapter.
• Updated index.md, conditions/sources landing pages.
• Next: Diverticular Disease (duodenal, jejunal/ileal, Meckel) and Miscellaneous Problems (ulcerations, foreign bodies, fistulas, pneumatosis intestinalis, blind loop syndrome, radiation enteritis, short bowel syndrome, vascular compression of duodenum) — the final ~16 pages of this chapter.

[2026-08-19] ingest | Sabiston Ch50 - Diverticular Disease & Miscellaneous Problems

• Third and final chunk of the Sabiston "Small Bowel" chapter (pages 46-61) — all 61 pages now ingested across 3 chunks, filed as reference sources per Stephen's original instruction. This completes the wiki's entire originally planned ingest list (5 primary-literature papers + both Sabiston textbook chapters).
• Added GIST mutation-directed prognosis/therapy detail (D842V PDGFRα resistance, exon 9 dosing, dasatinib/regorafenib/nilotinib/sorafenib) to Gastrointestinal Stromal Tumors (GIST), and a Metastatic Neoplasms subsection (melanoma as the leading extraabdominal source) to Small Bowel Neoplasms.
• Created Small Bowel Diverticular Disease as a new overview page (true vs. false diverticula), plus three detail pages: Duodenal Diverticula (intraluminal vs. extraluminal, biliary/ pancreatic complications, diverticulectomy technique), Jejunal and Ileal Diverticula, and Meckel Diverticulum (including the genuinely unresolved incidental-resection controversy — Soltero and Bill's historical conservative recommendation vs. more recent malignancy-risk-driven arguments for resection).
• Created seven new condition pages for the chapter's Miscellaneous Problems section: Small Bowel Ulcerations, Ingested Foreign Bodies, Enterocutaneous Fistula (three-phase management), Pneumatosis Intestinalis ("a radiographic finding, not a diagnosis"), Blind Loop Syndrome, Radiation Enteritis (acute/chronic forms, prevention, treatment), and Short Bowel Syndrome (adaptive hyperplasia, teduglutide, Bianchi/STEP procedures, intestinal transplantation), plus Vascular Compression of the Duodenum (SMA Syndrome).
• Rewrote wiki/Overview.md (previously stale, still saying "no sources ingested yet") with a current synthesis: what's in the wiki, the textbook-vs-primary-literature depth asymmetry across topics, and open next steps.
• Updated index.md, conditions/sources landing pages.
• Ingest list complete. No further sources currently queued — next steps (lint pass, further primary-literature ingest in a specific area, or leaving the wiki as-is) are open and should follow Stephen's direction.

[2026-08-19] lint | Vault-wide consistency pass

• Scanned all 77 files programmatically for broken wikilinks, orphaned pages, landing-page completeness, frontmatter validity, and cross-link symmetry, per Stephen's request for a "lint pass" now that the original ingest list is complete.
• Fixed: 10 wikilinks across 8 files (Familial Adenomatous Polyposis (FAP), Ileal Pouch-Anal Anastomosis (IPAA), Cytoreductive Surgery and HIPEC ×2, Total Neoadjuvant Therapy (TNT), Sabiston Ch52 - Diverticular Disease, Obstruction & Pseudo-Obstruction ×2, Inflammatory Bowel Disease, Colonic Pseudo-Obstruction (Ogilvie Syndrome), Large Bowel Obstruction, Boublikova 2023 - TNT in Rectal Cancer Review) had a literal line-wrap newline embedded inside the [[...]] brackets — a real Obsidian rendering bug (multi-line wikilinks don't resolve), predating this session. Collapsed each to a single line.
• Fixed: the three Sabiston Ch50 source pages created this session (Sabiston Ch50 - Small Bowel Anatomy, Physiology, Obstruction & Crohn Disease, Sabiston Ch50 - Infectious Enteritis & Small Bowel Neoplasms, Sabiston Ch50 - Diverticular Disease & Miscellaneous Problems) were missing the sources: [] frontmatter field that every other source page has — added for consistency.
• Fixed: added reciprocal cross-links — Large Bowel Obstruction now points to Small Bowel Obstruction (previously one-directional), and Infectious Colitis now points to Enteritis in the Immunocompromised Host (previously one-directional).
• Verified clean: zero broken wikilinks (alias-aware — Ladies Trial (LOLA).md's aliases: [Ladies Trial, LADIES Trial] frontmatter correctly resolves the many [Ladies Trial](guidelines-trials/Ladies%20Trial%20%28LOLA%29.html) links used elsewhere), zero orphaned pages (every condition/procedure/concept/source/guideline page has both a landing-page listing and at least one prose cross-link), zero landing-page gaps (every file on disk in each category folder is listed on both its category landing page and index.md), and all YAML frontmatter parses validly with type/tags/created/updated/sources present.
• Noted, not fixed: several source pages from before this session (Azhar, Boublikova, Hoehn, Lambrichts, Vennix, all Sabiston Ch52 pages) have an H1 heading using an em dash ("—") where the filename uses a hyphen ("-"), and Ladies Trial (LOLA).md's H1 reads "Ladies Trial" without the "(LOLA)" suffix. Purely cosmetic (Obsidian doesn't require H1-filename matching) and renaming the files to "fix" it would break every existing wikilink pointing to them — left as-is by design choice, not oversight.

[2026-08-19] ingest | ACG 2025 - Ulcerative Colitis Guideline

• Ingested the 2025 ACG Clinical Guideline Update: Ulcerative Colitis in Adults (Rubin et al., Am J Gastroenterol 2025;120:1187-1224) — full text, 38 pages, read in 3 chunks.
• New guideline page: guidelines-trials/ACG 2025 - Ulcerative Colitis Guideline.md (type trial-guideline). Raw PDF filed as raw/Rubin 2025 - ACG Clinical Guideline Update Ulcerative Colitis in Adults.pdf.
• Substantially expanded conditions/Ulcerative Colitis.md: new "Disease severity and monitoring" section (ACG UC Disease Activity Index, endoscopic-improvement treatment goal, fecal calprotectin as monitoring tool, intestinal ultrasound), new "Medical management" section (mild-moderate stepwise 5-ASA/budesonide/steroid approach; full moderate-severe advanced-therapy roster — anti-TNF, vedolizumab, ustekinumab, IL-23p19 inhibitors, JAK inhibitors, S1P modulators — with UC-specific positioning and trial evidence), new "Acute severe UC (ASUC)" section (full day 0/3/6 management algorithm from the guideline's Fig. 3). This closes a gap this wiki's own lint pass had flagged: UC medical management previously had zero primary-literature/guideline backing.
• Flagged and corrected an older-teaching point on the existing surgical-indications section: the guideline states neither infliximab nor cyclosporine rescue therapy increases postoperative colectomy complications, and surgery should not be delayed for a biologic "washout" — added as an explicit note rather than silently overwriting the prior fulminant-colitis text.
• Updated conditions/Inflammatory Bowel Disease.md's open items to flag the new UC/Crohn's asymmetry in medical-management sourcing (UC now guideline-backed, Crohn's still textbook-only).
• Updated index.md and guidelines-trials/Guidelines & Trials.md.
• Not yet cross-checked against the other two guidelines Stephen provided in the same batch (AGA Living Guideline on IBD Pharmacotherapy; British IBD 2025) — both queued for ingest next. Any disagreement between the three will be flagged explicitly once read.

[2026-08-19] ingest | AGA 2024 - Moderate-to-Severe UC Pharmacotherapy Guideline

• Ingested the AGA Living Clinical Practice Guideline on Pharmacological Management of Moderate-to-Severe Ulcerative Colitis (Singh et al., Gastroenterology 2024;167:1307-1343) — full text, 37 pages, read in 3 chunks.
• New guideline page: guidelines-trials/AGA 2024 - Moderate-to-Severe UC Pharmacotherapy Guideline.md (type trial-guideline). Raw PDF filed as raw/Singh 2024 - AGA Living Guideline Pharmacological Management Moderate-Severe UC.pdf.
• Expanded conditions/Ulcerative Colitis.md's Medical management section: new "Efficacy positioning" subsection and new "Combination therapy, de-escalation, and sequencing" subsection.
• Flagged an explicit cross-guideline methodological disagreement (not silently merged): the ACG 2025 guideline declines to rank therapies via network meta-analysis; this AGA guideline builds its entire higher/intermediate/lower efficacy-bucket system substantially on NMA p-scores. Documented as its own subsection on Ulcerative Colitis with both guidelines' positioning tables shown side by side rather than merged into one ranking.
• Updated index.md and guidelines-trials/Guidelines & Trials.md.
• Still queued: British IBD 2025 guideline (102pp) — the third and largest of the batch Stephen provided. Once ingested, cross-check all three for further agreement/disagreement.

[2026-08-19] ingest | BSG 2025 - IBD Guidelines (Adults)

• Ingested the British Society of Gastroenterology guidelines on the management of IBD in adults (Moran et al., Gut 2025;74:s1-s101) — full text, 102 pages (references start ~p.87), read in 5 chunks. By far the broadest of the three guidelines in this batch: covers both UC and Crohn's plus extensive cross-cutting content.
• New guideline page: guidelines-trials/BSG 2025 - IBD Guidelines (Adults).md (type trial-guideline). Raw PDF filed as raw/Moran 2025 - BSG Guidelines on the Management of IBD in Adults.pdf.
• Substantially expanded conditions/Crohn Disease.md — closes the wiki's single biggest IBD gap. New "Advanced therapy, monitoring, and post-surgical management" section: full GRADE-based advanced-therapy roster (adalimumab/infliximab with combination-therapy recommendations, ustekinumab, risankizumab, upadacitinib suggested; vedolizumab NOT suggested — a genuine disease-specific divergence from its favorable UC positioning, flagged explicitly as different from the ACG/AGA methodology disagreement), TDM specifics (purine metabolite and anti-TNF trough targets), EEN practical protocol, withdrawal-of-thertherapy guidance, post-surgical recurrence prevention (anti-TNF/vedolizumab within 90 days for high-risk patients), perioperative optimization. Also expanded the existing Perianal disease bullet with BSG's perianal Crohn's workup/treatment guidance (PISA-II trial, infliximab first-line, failed MSC therapy trial).
• Expanded conditions/Inflammatory Bowel Disease.md with cross-cutting content applicable to both diseases: new "Therapeutic drug monitoring", "Pregnancy", and "Perioperative management and superadded infection" sections; expanded "Extraintestinal manifestations" with PSC-IBD detail (annual surveillance colonoscopy timing) and spondyloarthropathy drug-specific guidance (which biologics to avoid).
• Light-touch note added to conditions/Ulcerative Colitis.md acknowledging BSG's UC content exists but wasn't exhaustively cross-checked against ACG/AGA-sourced specifics during this ingest — flagged as an explicit limitation rather than silently assumed consistent.
• Updated index.md and guidelines-trials/Guidelines & Trials.md.
• This completes the 3-guideline batch Stephen provided (ACG 2025, AGA 2024, BSG 2025). All three now cross-reference each other's positioning differences explicitly where they exist (ACG-vs-AGA: NMA methodology disagreement on UC; BSG: genuine efficacy-based vedolizumab divergence in Crohn's vs. UC).

[2026-08-19] ingest | 8 primary-literature trials — rectal cancer TNT cluster + NET cluster

• Ingested 8 primary-literature papers Stephen uploaded, closing the gaps flagged in this wiki's Open items after the earlier WebFetch-failure episode: 4 rectal-cancer neoadjuvant trials (RAPIDO, PRODIGE 23 long-term, STELLAR, PROSPECT) and 4 neuroendocrine-tumor trials (CLARINET, PROMID, RADIANT-4, NETTER-1).
• Filename correction: the uploaded NEJMoa2303269_RAPIDO.pdf is, despite its name, the PROSPECT trial (Schrag et al., NEJM 2023) — confirmed via DOI and full-text content, not the RAPIDO trial. The actual RAPIDO trial (Bahadoer et al., Lancet Oncol 2021) was separately uploaded as RAPIDO.pdf. Flagged explicitly in sources/Schrag 2023 - PROSPECT Trial.md.
• New source pages (all type: source, raw PDFs filed under raw/): sources/Bahadoer 2021 - RAPIDO Trial.md, sources/Conroy 2024 - PRODIGE 23 Long-Term Results.md, sources/Jin 2022 - STELLAR Trial.md, sources/Schrag 2023 - PROSPECT Trial.md, sources/Caplin 2014 - CLARINET Trial.md, sources/Rinke 2009 - PROMID Trial.md, sources/Strosberg 2017 - NETTER-1 Trial.md, sources/Yao 2016 - RADIANT-4 Trial.md.
• Substantially updated concepts/Total Neoadjuvant Therapy (TNT).md — Efficacy section rebuilt around a 3-trial comparison table (RAPIDO/PRODIGE23/STELLAR). Key finding to flag: the locoregional-recurrence trade-off previously described (from the Boublikova secondary review) as a general feature of TNT turns out to be RAPIDO-specific, not a consistent cross-trial finding — PRODIGE 23 and STELLAR both show numerically better, not worse, local control with TNT vs. standard CRT. Documented as an explicit unresolved cross-source disagreement per this wiki's contradiction-flagging convention, not silently resolved. OS benefit is similarly trial-dependent: clear/mature in PRODIGE 23, non-powered trend in STELLAR, absent in RAPIDO (partly attributed to an "ATRESS phenomenon" not observed in PRODIGE 23).
• Updated conditions/Rectal Cancer.md — new "Neoadjuvant trial evidence: TNT and radiation- omission" section summarizing the 4 trials' treatment-selection implications; Open items updated (POLISH II and the IDEA duration collaboration remain the only un-ingested primary trials in this area).
• Updated conditions/Small Bowel Neuroendocrine Tumors (NETs).md — Medical therapy section rewritten with precise primary-source figures replacing the prior textbook-only narrative (PROMID: TTP 14.3 vs 6.0mo, HR 0.34; CLARINET: PFS not reached vs 18.0mo, HR 0.47; RADIANT-4: PFS 11.0 vs 3.9mo, HR 0.48 — confirmed accurate against the textbook's prior paraphrase; NETTER-1: HR 0.21, PFS not reached vs 8.4mo — corrected the textbook's "79% PFS improvement" framing to the more precise "79% lower risk of progression/death"). Open items updated — TELESTAR remains un-ingested.
• Updated index.md and sources/Sources.md with all 8 new source entries.
• Not pursued: no new guidelines-trials/ trial-entity pages were created for these 8 papers (unlike the SCANDIV/Ladies Trial precedent) — TNT.md and the NETs condition page already serve as adequate synthesis anchors and previously narratively referenced these trials, so separate entity pages would be redundant at this scope.

[2026-08-19] lint | Full wiki lint pass

• Broken links: none. Checked every [[wikilink]] against filenames and frontmatter aliases (Obsidian resolves via both) — [[Ladies Trial]] (9 instances) correctly resolves to Ladies Trial (LOLA).md via its declared alias; not actually broken.
• Orphan pages: none — every page has at least one inbound link.
• Landing-page and index.md completeness: all 5 folder landing pages list every page in their folder, and index.md catalogs every page across all folders. No gaps found.
• Frontmatter: the 5 folder landing pages (Sources.md, Conditions.md, Concepts.md, Procedures.md, Guidelines & Trials.md) have no YAML frontmatter, consistent with index.md/log.md/Overview.md. Treated as by-design (pure navigation pages, don't fit the type: enum) rather than a defect — flagged to Stephen, no change made pending his decision on whether to codify this exemption explicitly in CLAUDE.md.
• Superseded claim, fixed: conditions/Appendiceal Neoplasms.md's "Advanced/metastatic disease" section and Open items still described PROMID/CLARINET/RADIANT-4/NETTER-1 as un-ingested, secondhand-only (via Hoehn's review) — stale as of the 2026-08-19 8-paper ingest. Updated to cite the primary source pages directly, cross-link to Small Bowel Neuroendocrine Tumors (NETs)'s Medical therapy synthesis, and note these trials studied midgut/GI NET populations generally rather than appendiceal NETs specifically (Hoehn extrapolates). RADIANT-2 noted as still not independently ingested. Frontmatter sources[] expanded accordingly.
• Stale aside, fixed: guidelines-trials/ACG 2025 - Ulcerative Colitis Guideline.md's Relevance section said NETTER-1/PROMID/CLARINET/RADIANT-4 "remain unaddressed" — no longer true after the same ingest. Reworded to note they were independently ingested separately, with a cross-link to the NETs page.
• Concept gaps (MRF, EMVI, pCR lacking standalone pages): already self-flagged in Rectal Cancer.md and Total Neoadjuvant Therapy (TNT).md's own Open items from the prior ingest — not a new finding.
• Web-search-worthy gaps: not pursued without sign-off. Largest remaining: POLISH II (TNT) and RAPIDO's 5-year follow-up (Dijkstra et al., Ann Surg 2023), both already noted as open items.

[2026-08-19] query | Research priorities synthesis

• Stephen asked what studies are needed to expand the knowledge base. Swept every page's "Open items / gaps" section (~40 pages) and synthesized into a new tracking page, wiki/Research Priorities.md — a checkbox-organized punch list grouped into: named studies that resolve a specific already-flagged gap (RAPIDO 5-year follow-up, POLISH II, IDEA duration collaboration, TELESTAR, RADIANT-2, DILALA, LapLAND, SCANDIV 90-day/1-year reports, PRODIGE 7, COLOPEC, mitomycin-vs-oxaliplatin RCT, BALLAD, Crohn's-specific ACG/AGA guidelines, IDSA/SHEA C. diff guideline); condition pages with zero primary literature (Appendiceal Neoplasms' non-NET subtypes, GIST, Short Bowel Syndrome, Radiation Enteritis, Enterocutaneous Fistula, Meckel Diverticulum, Rectal Prolapse/Rectocele/SRUS, hereditary CRC syndromes); and contested clinical questions worth a dedicated source (stenting-as-bridge for obstructing colon cancer, antibiotics-vs-none for uncomplicated diverticulitis, taTME long-term outcomes vs. conventional TME). Placed at wiki/ root (no frontmatter, alongside index.md/log.md/Overview.md) since it's a meta/tracking page, not an entity page — doesn't fit the type: enum. Not added to index.md's catalog, consistent with how index.md excludes the other root meta pages.

[2026-08-20] ingest | 5 primary-literature trials — RAPIDO 5-yr follow-up, POLISH II, PRODIGE 7,

GRECCAR16 and JANUS protocols

• Stephen uploaded 5 papers directly requested from Research Priorities's punch list: GRECCAR16, JANUS, POLISH II, PRODIGE7, and "RAPIDO 5yr" (the actual filenames matched their content — no mislabeling this time).
• New source pages: Ciseł 2019 - POLISH II Long-Term Results, Dijkstra 2023 - RAPIDO 5-Year Locoregional Failure, Quénet 2021 - PRODIGE 7 Trial, Brouquet 2020 - GRECCAR16 Trial Protocol, Alvarez 2024 - JANUS Trial Protocol.
• GRECCAR16 and JANUS turned out to be study-protocol papers, not results papers — flagged explicitly on their own source pages and in Total Neoadjuvant Therapy (TNT): GRECCAR16 (FOLFIRINOX replacing radiotherapy entirely vs. standard CRT, N=574 target, no results yet) and JANUS (Alliance A022104/NRG-GI010: triplet vs. doublet consolidation chemotherapy after LCRT for cCR/DFS, 330/760 accrued as of May 2024, no results yet). Both were previously known to the wiki only as vague "ongoing trial" mentions in the Boublikova review / PRODIGE 23's discussion — now their actual design, primary endpoints, and rationale are documented, even though efficacy data remains pending.
• Dijkstra 2023 - RAPIDO 5-Year Locoregional Failure resolves this wiki's most significant open question: at 5.6-year follow-up, RAPIDO's locoregional recurrence rate with TNT is now statistically significantly higher than with standard CRT (10.2% vs 6.1% after R0/R1 resection, P=0.027) — this was only a non-significant numerical trend at the original 3-year analysis. The systemic-control benefit (disease-related treatment failure, distant metastases) remains durable at 5 years; OS remains unchanged between arms. This confirms the locoregional trade-off as a real, RAPIDO-specific finding — still not observed in PRODIGE 23 or STELLAR.
• Ciseł 2019 - POLISH II Long-Term Results adds a fourth trial to the cross-trial TNT comparison table, and it's a genuine outlier: a truly neutral result — no OS, DFS, local-control, or distant-metastasis difference in either direction at 8 years, and an early 3-year OS advantage for the short-course/consolidation-chemo arm that did not persist. Useful counterexample against over-generalizing from the other three trials.
• Quénet 2021 - PRODIGE 7 Trial closes the "no primary HIPEC trial data" gap on Cytoreductive Surgery and HIPEC — confirms no OS/RFS benefit from adding HIPEC to CRS for colorectal peritoneal metastases (previously known only via a secondary review), and adds a new detail not previously in the wiki: HIPEC was associated with significantly more morbidity at 60 days (26% vs 15%, P=0.035).
• Updated: concepts/Total Neoadjuvant Therapy (TNT).md (Efficacy table now has 4 trials + RAPIDO 5-yr row, trade-off framing rewritten as "confirmed RAPIDO-specific, not a class effect", Modalities section updated with actual JANUS/GRECCAR16 protocol detail, Open items updated); conditions/Rectal Cancer.md (Neoadjuvant trial evidence section rewritten with 5-year RAPIDO data and POLISH II, Open items updated); concepts/Cytoreductive Surgery and HIPEC.md (PRODIGE 7 primary data replaces secondhand summary, Open items updated); Research Priorities.md (checked off POLISH II, RAPIDO 5-yr, PRODIGE 7, GRECCAR16/JANUS protocols; added ACO/ARO/AIO-18 and GRECCAR 14 as still-secondhand-only); sources/Sources.md, index.md updated with all 5 new entries.
• Not pursued: no new guidelines-trials/ entity pages created for these 5 papers, consistent with the precedent set during the 2026-08-19 8-paper ingest — the relevant concept/condition pages already serve as synthesis anchors.

[2026-08-20] lint | Post-ingest consistency pass

• Full 6-category lint pass (contradictions, superseded claims, orphans/broken links, missing concept pages, missing cross-references, gaps) plus a frontmatter/index spot-check, run after the 2026-08-20 5-paper ingest. No contradictions, no orphan pages, no broken links, index fully accurate — findings were all staleness/gaps left behind by that ingest, not caught by the prior (pre-ingest) lint pass. All fixes below applied per Stephen's "apply all" instruction.
• Fixed 5 stale "not yet ingested" notes that a same-day or next-day ingest had since resolved: sources/Bahadoer 2021 - RAPIDO Trial.md (now points to Dijkstra 2023 - RAPIDO 5-Year Locoregional Failure as confirming, not secondhand, the 5-year trade-off); sources/Vennix 2015 - Ladies Trial LOLA.md (now links Lambrichts 2019 - LADIES DIVA Trial as ingested); guidelines-trials/ACG 2025 - Ulcerative Colitis Guideline.md and guidelines-trials/AGA 2024 - Moderate-to-Severe UC Pharmacotherapy Guideline.md (both now note the AGA/BSG and BSG cross-checks are done, pointing to Ulcerative Colitis's synthesis); conditions/Ulcerative Colitis.md (deleted an Open items bullet that contradicted the correct bullet two lines below it).
• Added 2 missing cross-references: conditions/Rectal Cancer.md's metastatic-disease section now points to Cytoreductive Surgery and HIPEC for peritoneal spread; conditions/Appendiceal Neoplasms.md now links Colon Cancer Resection for right-hemicolectomy technique and its Open items bullet (which wrongly claimed no such page existed) is corrected.
• Frontmatter cleanup: Overview.md was missing created: — added (2026-08-18, the vault scaffold date); type: overview added to CLAUDE.md's declared type enum to match. Research Priorities.md given tags: [meta] frontmatter, consistent with the other 8 meta/landing pages tagged earlier this session.
• Rewrote Overview.md (per its own stated convention — rewritten, not appended to) to reflect the full current state: the four primary-literature clusters (rectal cancer TNT, diverticulitis, appendiceal/NET, IBD guidelines), three completed lint passes, and Research Priorities.md as the live gap-tracker, replacing the 2026-08-19 snapshot that predated this session's ingest.
• Added 2 new tracked gaps to Research Priorities.md: OPRA trial (referenced by name in 3 pages as the key NOM/organ-preservation data point, never independently ingested) and VARSITY trial (the one head-to-head UC biologic RCT both ACG and AGA guidelines lean on, known only secondhand).
• Not changed: the "Colon Cancer as its own condition page" question raised in the lint report — a judgment call flagged for Stephen's input, not a clear defect, so left as-is pending direction.

[2026-08-24] ingest | ASCRS Ch01 - Anatomy and Embryology

• New source added to raw/: ASCRS Textbook of Colon and Rectal Surgery, 4th ed. — 1,198 pages, 72 chapters across 6 parts. Full TOC extracted and scope discussed with Stephen before writing anything; he chose sequential front-to-back ingest, one chapter at a time. This entry covers Chapter 1 only.
• Created sources/ASCRS Ch01 - Anatomy and Embryology.md — citation, scope, and key-content pointer for Ch. 1 (Carmichael & Mills), PDF pp. 20–44 of the combined textbook file (cited by page range within the single-file PDF, not a separate per-chapter document).
• Created concepts/Colorectal Anatomy & Embryology.md — anal canal (anatomic vs. surgical definitions), sphincter complex, pelvic floor muscles, rectal anatomy (fascial planes, blood supply, valves), anorectal spaces, colonic anatomy/blood supply, and GI embryology (midgut rotation stages/anomalies, congenital anomalies).
• Discrepancy flagged, not resolved: conditions/Rectal Cancer.md now has a blockquote noting this chapter's rectal measurement/thirds differ from the figures already in that page — left as an open discrepancy per convention, not silently reconciled.
• Corroboration added: conditions/Meckel Diverticulum.md gets a new "Corroborating source" section — this chapter's brief, independent mention of Meckel diverticulum (location, ectopic tissue, Littre's hernia, incidence, "no hard indication for excision") is consistent with, though much thinner than, the existing Sabiston-sourced treatment.
• Updated sources/Sources.md, concepts/Concepts.md, and index.md (Sources + Concepts sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 2, "Colonic Physiology" (PDF pp. 45–56).

[2026-08-24] ingest | ASCRS Ch02 - Colonic Physiology

• Second chapter of the sequential ASCRS ingest, continuing directly from Ch01 above.
• Created sources/ASCRS Ch02 - Colonic Physiology.md — citation, scope, key-content pointer for Ch. 2 (Ault & Beaty), PDF pp. 45–56.
• Created concepts/Colonic Physiology.md — colonic wall histology (epithelial types, ICC, myenteric/submucosal plexuses), secretory/absorptive ion transport (Na/K/aldosterone/CFTR, SCFA, vitamin K), innervation, visceral pain, motility (segmental/propagated contractions, colonic/rectal motor complexes, defecation physiology incl. the rectoanal inhibitory reflex — new to the wiki), a detailed pharmacology section on motility modulators, and gut microbiome composition/disease associations.
• concepts/Colorectal Anatomy & Embryology.md gained one new detail from this chapter's embryology recap (added directly rather than duplicated): anal sphincter developmental timing (external ~week 10, internal ~week 12) — plus a cross-link to the new page and an added source entry.
• Discrepancy flagged, not resolved: conditions/Crohn Disease.md now has a blockquote noting this chapter's microbiome section reports Bacteroidetes as elevated (not decreased) in Crohn's disease, conflicting with the existing Sabiston-sourced dysbiosis description — flagged bidirectionally (also flagged on the new Colonic Physiology.md page).
• Mechanistic depth added: conditions/Constipation.md's medical-management section now points to Colonic Physiology.md's modulators-of-motility section for mechanism detail behind the medications it names (lubiprostone, linaclotide, prucalopride) plus additional agents not previously covered (alosetron, bile-acid modulation, sacral nerve stimulation).
• concepts/Small Intestine Anatomy & Physiology.md got a new "Related pages" section cross-linking the new colonic-physiology companion page — together the two now cover GI physiology end to end from duodenum through anal canal.
• Updated sources/Sources.md, concepts/Concepts.md, and index.md (Sources + Concepts sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 3, "Anorectal Physiology" (PDF pp. 57+).

[2026-08-24] ingest | ASCRS Ch03 - Anorectal Physiology

• Third chapter of the sequential ASCRS ingest, continuing directly from Ch02 above (per Stephen's "you can keep going").
• Created sources/ASCRS Ch03 - Anorectal Physiology.md — citation, scope, key-content pointer for Ch. 3 (Suwanabol & Regenbogen), PDF pp. 57–66.
• Created concepts/Anorectal Physiology.md — innervation of the anus/pelvic floor, normal continence (rectal sensation/compliance, anorectal reflexes incl. the RAIR, IAS/EAS roles, puborectalis mechanism), normal defecation sequence.
• Created conditions/Fecal Incontinence.md — a genuinely new topic (previously touched only within Rectal Prolapse (Procidentia)'s prolapse-specific context): sphincter-defect, idiopathic, and neurologic incontinence pathophysiology; disorders of defecation (dyssynergia/anismus); anorectal pain (chronic proctalgia/levator ani syndrome vs. proctalgia fugax); urogynecologic overlap.
• concepts/Colonic Physiology.md's RAIR paragraph was trimmed and redirected to the new Anorectal Physiology.md (avoiding duplication) — includes a consistency note (not flagged as a contradiction) between Ch. 2's "~80% resting tone from IAS" and Ch. 3's "~50–70% IAS + ~15% hemorrhoid complexes" framing.
• concepts/Anorectal Physiology Testing.md extended (not duplicated) with new detail from Ch. 3: high-pressure-zone length (2.0–4.0 cm), balloon insufflation as a distinct rectal-sensation test (first sensation/urge/max tolerable volume), PNTML's incontinence/prolapse associations, and a corroboration note on defecography.
• conditions/Constipation.md's anismus open-item gap updated to point to Fecal Incontinence.md's fuller pathophysiology account (treatment still deferred by both sources).
• conditions/Rectal Prolapse (Procidentia).md gained a cross-link to Fecal Incontinence.md for the general (non-prolapse) incontinence mechanisms.
• Updated sources/Sources.md, concepts/Concepts.md, conditions/Conditions.md, and index.md (Sources + Concepts + Conditions sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 4, "Endoscopy" (PDF pp. 67+).

[2026-08-24] ingest | ASCRS Ch04 - Endoscopy

• Fourth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going." Notably longer and more technique/practice-management-focused than Ch01–03.
• Created sources/ASCRS Ch04 - Endoscopy.md — citation, scope, key-content pointer for Ch. 4 (Zelhart & Kann), PDF pp. 67–93.
• Created procedures/Colonoscopy & Lower GI Endoscopy.md — anorectal exam (DRE, anoscopy, proctoscopy, EAUS/ERUS), flexible endoscopy technique fundamentals, flexible sigmoidoscopy, and a full colonoscopy treatment (bowel prep categories/split-dosing, sedation options, instrumentation, procedural technique through all colonic segments, terminal ileal intubation debate, alternative insufflation/imaging techniques, difficult exams, incomplete colonoscopy and its imaging follow-up, and a detailed complications section — perforation, post-polypectomy bleeding/syndrome, splenic injury, infectious risk), plus endoscopy-unit operations, quality measures (withdrawal time, ADR, the emerging APC metric), the leasing-vs-purchasing equipment decision, and training/ simulation (FEC/FES, ACGME case minimums, GAGES).
• Corroboration/quantification added: conditions/Rectal Cancer.md's ERUS staging bullet and concepts/Anorectal Physiology Testing.md's endoanal ultrasound bullet both gained the new chapter's quantified accuracy figures (66–92% T-stage, 64–88% nodal) — no contradiction, just numbers where the wiki previously had qualitative statements only.
• Cross-reference added: conditions/Diverticulitis.md's post-recovery colonoscopy note now flags severe diverticular disease as a colonoscopic perforation risk factor per the new page.
• Updated sources/Sources.md, procedures/Procedures.md, and index.md (Sources + Procedures sections) with the two new pages.
• Not done this round (flagged as light-touch, not full cross-reference sweep): the new page also names Ischemic Colitis, Ulcerative Colitis, and Crohn Disease as relevant (perforation risk / chromoendoscopy surveillance) in its own Related Pages section, but those three pages were not individually edited — a future lint pass could add reciprocal links if Stephen wants full bidirectionality.
• Next up (pending Stephen's go-ahead): Chapter 5, "Endoscopic Management of Polyps and Endolumenal Surgery" (PDF pp. 94+).

[2026-08-24] ingest | ASCRS Ch05 - Endoscopic Management of Polyps and Endolumenal Surgery

• Fifth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going."
• Created sources/ASCRS Ch05 - Endoscopic Management of Polyps and Endolumenal Surgery.md — citation, scope, key-content pointer for Ch. 5 (Johnston & Gorgun), PDF pp. 94–108.
• Created procedures/Endoscopic Polypectomy, EMR & ESD.md — forceps/snare polypectomy technique and current ESGE size-based recommendations, submucosal lifting agents/technique, EMR (incl. underwater EMR, selective clip use for large proximal polyps), ESD (patient selection via Paris/ NICE classification and the non-lifting sign, full technique, complications, the hybrid ESD/EMR approach, the ESD-vs-EMR risk/benefit controversy), endoscopic suturing and stabilization platforms, the step-up referral approach for "unresectable" polyps, and colonic stenting (bridge-to-surgery vs. palliative indications, technique, anastomotic-leak stenting).
• Duplication trimmed: procedures/Local Excision of Rectal Neoplasms.md's prior brief EMR/ESD mechanistic summary now points to the new page instead of restating it.
• Gaps filled on existing pages (both previously flagged as open items): conditions/Large Bowel Obstruction.md's "endoscopic stent outcomes not covered" gap now has the specific complication rates (perforation 5%, migration 4–10%, reobstruction 30%) and the fivefold-lower-permanent-stoma outcome data. conditions/Obstructing Colon Cancer.md's "no comparative stenting-vs-surgery data" gap is refined — the specific ESGE 2014 guideline and its risk-stratified (ASA ≥3/age >70) recommendation are now named, though primary trial data is still not independently ingested.
• Updated sources/Sources.md, procedures/Procedures.md, and index.md (Sources + Procedures sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 6, "Preoperative Evaluation in Colorectal Patients" (PDF pp. 109+) — a long chapter (cardiac/pulmonary risk assessment, frailty, elderly patients, prehabilitation).

[2026-08-24] ingest | ASCRS Ch06 - Preoperative Evaluation in Colorectal Patients

• Sixth chapter of the sequential ASCRS ingest, continuing per Stephen's confirmation that the de-duplication approach is working as intended ("There will be a lot of duplicate information, thanks for not duplicating it").
• Created sources/ASCRS Ch06 - Preoperative Evaluation in Colorectal Patients.md — citation, scope, key-content pointer for Ch. 6 (Landmann & Francone), PDF pp. 109–134.
• Created concepts/Preoperative Evaluation & Perioperative Risk Optimization.md — routine preoperative testing; cardiac evaluation (RCRI, functional capacity/METs, medical optimization, beta-blocker warning); preoperative anticoagulation (warfarin, DOACs, coronary stents, bridging via HAS-BLED/CHA2DS2-VASc, prosthetic valves, AICD/pacemakers); pulmonary assessment (COPD, smoking cessation, OSA); perioperative steroid management (HPA-axis suppression, stress-dose steroid controversy); diabetes; obesity; malnutrition/sarcopenia (SGA); solid organ transplant recipients (mTOR-inhibitor wound-healing risk); substance abuse; immunosuppressive agents/ biologics/chemotherapy and anastomotic-healing risk (the chapter's own "quite conflicting and controversial" framing preserved); preoperative assessment in the elderly (frailty models, CGA, cognitive dysfunction/delirium); and prehabilitation (mixed outcome evidence).
• This was an unusually cross-cutting chapter — rather than creating many new condition/ procedure pages, most of its content extends existing pages with quantified detail or explicit cross-references, continuing the de-duplication pattern Stephen flagged as working well:
• Framing difference flagged (not a contradiction): conditions/Crohn Disease.md's existing BSG-guideline perioperative-optimization text ("reassuring" data on biologics/anti-TNF and anastomotic infection risk, citing PUCCINI/REMIND) is now cross-linked to the new page, which presents the same PUCCINI finding embedded in a messier, older literature (Wong meta-analysis OR 1.5, institutional data OR 3.5, NSQIP OR 1.25–1.47, vedolizumab-specific increased-risk data) that the chapter itself calls "quite conflicting and controversial." Flagged as a synthesis-confidence difference between a guideline's graded read and a textbook narrative, not a factual conflict.
• Quantified: conditions/Diverticulitis.md's brief immunocompromised-patient bullet gained specific figures (40% emergent-op rate vs. 10–25% general population, 6.9% mortality) and a practice-changing nuance — prophylactic colectomy in immunosuppressed quiescent diverticulitis is no longer recommended, contrary to older teaching.
• Quantified: concepts/Total Neoadjuvant Therapy (TNT).md's existing bevacizumab healing- risk mention gained specific figures (OR 2.85 for anastomotic leak; 9-week median hold interval with leaks still occurring in 6/78 patients) and a slightly more conservative ≥6-week hold recommendation.
• Extended: procedures/Ileal Pouch-Anal Anastomosis (IPAA).md's obesity/tension-free-reach content now also notes obesity's independent effect on pouch-anal leak rate, distinct from the mechanical reach difficulty already documented there.
• Updated sources/Sources.md, concepts/Concepts.md, and index.md (Sources + Concepts sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 7, "Optimizing Outcomes with Enhanced Recovery" (PDF pp. 135+).

[2026-08-24] ingest | ASCRS Ch07 - Optimizing Outcomes with Enhanced Recovery

• Seventh chapter of the sequential ASCRS ingest, continuing per Stephen's "We can continue."
• Created sources/ASCRS Ch07 - Optimizing Outcomes with Enhanced Recovery.md — citation, scope, key-content pointer for Ch. 7 (Thacker & Morin), PDF pp. 135–153.
• Created concepts/Enhanced Recovery After Surgery (ERAS).md — the first genuinely new top-level topic in several chapters (no prior wiki page covered ERAS as its own subject). Covers ERAS origins/history (Kehlet, Wilmore, ERAS Society), the five-phase model of care, preoperative elements (education, smoking cessation, nutrition/PONS score, anemia workup, hyperglycemia/HbA1c triage, carbohydrate loading, bowel prep), in-hospital preoperative elements (PONV prophylaxis, multimodal analgesia, VTE prophylaxis), intraoperative elements (multimodal analgesia, intentional fluid management — including a flagged genuine controversy between an AKI signal in one large RCT and a Mayo Clinic study not replicating it, MIS, minimal drains), postoperative elements (early diet/mobilization, discharge criteria), special populations (stoma creation/reversal, emergency surgery/trauma, elderly, IBD), economic impact ($3,101/patient savings), and future directions.
• Cross-references added (no new pages needed for these — extended existing pages instead): procedures/Ileal Pouch-Anal Anastomosis (IPAA).md's loop-ileostomy diversion section now points to the new page's stoma-education ERAS findings (including a Norwegian RCT on dedicated ERAS/stoma nurse specialists). conditions/Crohn Disease.md gained a new blockquote on IBD-specific ERAS outcomes — higher baseline complication risk on NSQIP data, but still net benefit from ERAS implementation. concepts/Preoperative Evaluation & Perioperative Risk Optimization.md is now cross-linked bidirectionally with the new page where the two chapters' content overlaps (preoperative hyperglycemia management, VTE prophylaxis) — flagged as complementary rather than duplicative (Ch6 = risk assessment/stratification, Ch7 = recovery pathway/protocol).
• Updated sources/Sources.md, concepts/Concepts.md, and index.md (Sources + Concepts sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 8, "General Postoperative Complications" (PDF pp. 154+).

[2026-08-24] ingest | ASCRS Ch08 - General Postoperative Complications

• Eighth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going."
• Created sources/ASCRS Ch08 - General Postoperative Complications.md — citation, scope, key-content pointer for Ch. 8 (Chu & Maron), PDF pp. 154–168.
• Created concepts/General Postoperative Complications.md — the second genuinely new cross-cutting topic in a row (after Ch7's ERAS page): complication epidemiology/risk factors (non-modifiable: age, sex, morbidities, prior surgery; modifiable: nutrition, smoking, anemia, sarcopenia, obesity, functional capacity, open approach), risk calculators (POSSUM, APACHE, ACS-NSQIP), and management organized by organ system in ACS-NSQIP frequency order: gastrointestinal (ileus, postop small bowel obstruction/ESBO), hematologic (bleeding/transfusion, presacral bleeding, abdominal compartment syndrome, VTE with Caprini/Roger risk stratification), infectious (SSI five-core-theme prevention bundle, wound dehiscence incl. the STITCH trial, UTI, C. diff), pulmonary (respiratory failure, pneumonia, aspiration), renal (AKI, postoperative urinary retention incl. tamsulosin prevention data), cardiac (MI, postoperative atrial fibrillation), and neurological (perioperative stroke, sexual dysfunction, postoperative delirium). Deliberately did not cover anastomotic leaks — the source chapter itself defers that topic to ASCRS Ch10 ("Anastomotic Complications," not yet ingested), so this page follows suit rather than duplicating Colorectal Anastomotic Complications's existing Sabiston-sourced content.
• Quantification/gap-filling added to existing pages: procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md's qualitative sexual-dysfunction mention gained specific incidence figures (71% postop erectile dysfunction vs. 24% preop, 78% ejaculatory dysfunction vs. 32%, sildenafil RCT data). procedures/Abdominoperineal Resection (APR).md's previously-flagged open item on sexual/urinary dysfunction is now partially addressed (general proctectomy data added; APR-specific comparison vs. LAR remains unquantified — open item narrowed, not closed). conditions/Infectious Colitis.md gained a surgical-patient-specific C. diff incidence figure (0.2–8.4% postop) cross-linked to its existing fuller epidemiology/treatment content. concepts/Colorectal Anastomotic Complications.md gained a forward-pointer flagging that a future ASCRS Ch10 ingest should reconcile/extend it.
• Cross-linked bidirectionally with the two most recent concept pages: concepts/Preoperative Evaluation & Perioperative Risk Optimization.md (shared cardiac-risk, VTE, and frailty/delirium territory — that page is preoperative assessment, this page is postoperative outcome data) and concepts/Enhanced Recovery After Surgery (ERAS).md (shared ileus, AKI/fluid-management, and POUR/PONV territory).
• Updated sources/Sources.md, concepts/Concepts.md, and index.md (Sources + Concepts sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 9, "Anastomotic Construction" (PDF pp. 169+).

[2026-08-24] ingest | ASCRS Ch09 - Anastomotic Construction

• Ninth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going."
• Created sources/ASCRS Ch09 - Anastomotic Construction.md — citation, scope, key-content pointer for Ch. 9 (Vargas & Margolin), PDF pp. 169–199 (a long chapter, split across two Read calls).
• Created procedures/Anastomotic Construction.md — a third consecutive genuinely new cross-cutting topic: physiology of anastomotic healing (collagen/tensile-strength phases, epithelial restitution, microbiome role), fundamental construction principles, mobilization technique (small bowel, splenic flexure, high-vs-low IMA tie, retroileal anastomosis/ileal mesenteric window, right colon de-rotation/Deloyer's procedure), perfusion assessment (clinical assessment and ICG fluorescence angiography incl. PILLAR II trial), anastomosis configuration (Cheatle slit, Barcelona anastomosis, Kono-S anastomosis, low pelvic reservoir options), sutured vs. stapled vs. compression-ring methods, and a detailed, explicitly unresolved review of conflicting stapled-vs-hand-sewn leak-rate evidence across German/Danish/European right-colectomy registries.
• Widest cross-link fan-out of any chapter in this ingest so far — six existing pages extended: conditions/Crohn Disease.md's brief Kono-S mention gained full construction technique detail; procedures/Colon Cancer Resection.md's high-vs-low IMA tie content (genitourinary-nerve framing) gained a complementary mesenteric-length framing of the same decision; conditions/Low Anterior Resection Syndrome (LARS).md's reservoir-options content gained outcome-comparison data (ACS-NSQIP J-pouch vs. straight anastomosis findings, STE-vs-J-pouch functional equivalence), partially filling its previously-flagged "no head-to-head data" open item; procedures/Ileal Pouch-Anal Anastomosis (IPAA).md and procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md both gained pointers to the new page's general stapled-vs-hand-sewn discussion as broader context for their procedure-specific anastomosis choices; concepts/Colorectal Anastomotic Complications.md gained a pointer to the new page's technique-comparison leak-rate data (distinct from that page's own leak-management focus, and from the still-not-ingested ASCRS Ch10 it's already flagged as awaiting).
• Updated sources/Sources.md, procedures/Procedures.md, and index.md (Sources + Procedures sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 10, "Anastomotic Complications" (PDF pp. 200+) — directly relevant to reconciling/extending concepts/Colorectal Anastomotic Complications.md, which multiple recent chapters (Ch8, Ch9) have flagged as awaiting this ingest.

[2026-08-24] ingest | ASCRS Ch10 - Anastomotic Complications

• Tenth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going." Closes out Part I ("Perioperative/Endoscopy") of the textbook — Chapter 11 ("Hemorrhoids") begins Part II ("Anorectal Disease").
• Created sources/ASCRS Ch10 - Anastomotic Complications.md — citation, scope, key-content pointer for Ch. 10 (Friel & Kin), PDF pp. 200–218 (single Read call, 19 pages).
• Rewrote concepts/Colorectal Anastomotic Complications.md substantially in place rather than creating a duplicate page — the clearest example yet of the "reconcile, don't duplicate" pattern, closing a gap explicitly flagged as pending since Ch8's deferral. Frontmatter sources now cites all of Sabiston Ch52, ASCRS Ch08, Ch09, and Ch10. Changes:
• Anastomotic leak section heavily extended: full risk-factor list (diabetes/HbA1c, male sex, BMI, tobacco, IBD, immunosuppressives, radiation enteritis, malnutrition, hypoalbuminemia, active infection, multiple stapler firings); diversion/drain benefit framed as unclear for leak prevention but clear for reducing septic-complication severity; emerging microbiome research (E. faecalis/collagenase/MMP9, P. aeruginosa) flagged as active, not settled; diagnosis extended with quantified CRP cutoffs (day 3 <172 mg/L, day 4 <124 mg/L, day 5 <144 mg/L = 97% NPV; open vs. laparoscopic thresholds) and procalcitonin (<2.7 ng/mL day 3 = 98.3% NPV); timing revised (up to half of leaks present post-discharge, a third of LAR leaks present >1 month out); management algorithm extended with newer endoscopic salvage techniques (vacuum sponge, covered SEMS, over-the-scope clips); new content on chronic presacral sinus tracts.
• New section: Outcomes after anastomotic leak — mortality (3–14%), 5-year overall and cancer-specific survival impact, permanent ostomy risk, functional/QoL/sexual/urinary effects, and a mechanistic link to LARS via pelvic fibrosis (cross-linked below).
• New section: Anastomotic fistula — technical-error fistulas (colovaginal from stapler misfire, ureteral/urethral injury) distinguished from leak-derived fistulas; epidural abscess noted as a rare, morbid variant.
• New section: Blind loop syndrome — as a distinct complication of side-to-side antiperistaltic anastomoses, with conversion to end-to-end as treatment.
• Anastomotic bleeding section extended: quantified incidence (up to 5%, 2.3% under a strict definition), management algorithm (endoscopy preferred over angiography/surgery), and the Cochrane hand-sewn-vs-stapled bleeding comparison (3.1% vs. 5.4%, not significant).
• Anastomotic stricture section extended: incidence by anastomosis type (IPAA/coloanal highest, ileocolic lowest), Cochrane stapled-vs-hand-sewn stricture data (8% vs. 2% left-sided), full treatment ladder (digital/bougie dilation, endoscopic balloon dilation 67–100% success, EECI 90–100% success, SEMS, surgical revision 57–100%/79% pooled success), and permanent colostomy reframed as a legitimate QoL choice rather than a treatment failure.
• Necrosis-of-transposed-colon and twisting sections left unchanged (Sabiston-specific, not covered by Ch10).
• Open items/gaps trimmed to the two genuinely still-open items (diverting-stoma selection/timing data gap; microbiome-research maturity caveat).
• Reciprocal cross-links added: conditions/Low Anterior Resection Syndrome (LARS).md gained a mechanistic explanation (leak-induced pelvic fibrosis reducing neorectal compliance) linking its existing leak-association note to a plausible cause; concepts/Enhanced Recovery After Surgery (ERAS).md gained a cross-reference from its discharge-criteria content to the new CRP/procalcitonin-based leak-surveillance data as relevant to early-discharge risk assessment. Both pages' frontmatter sources updated to add Ch10.
• Updated sources/Sources.md and index.md (Sources + Concepts sections) with the new source page and the expanded Colorectal Anastomotic Complications blurb.
• Next up (pending Stephen's go-ahead): Chapter 11, "Hemorrhoids" (PDF pp. 219+) — the first chapter of Part II, "Anorectal Disease."

[2026-08-24] ingest | ASCRS Ch11 - Hemorrhoids

• Eleventh chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going." First chapter of Part II ("Anorectal Disease").
• Created sources/ASCRS Ch11 - Hemorrhoids.md — citation, scope, key-content pointer for Ch. 11 (Davids & Ridolfi), PDF pp. 219–238 (single Read call, 20 pages).
• Created conditions/Hemorrhoids.md — a genuinely new, comprehensive condition page, and the first dedicated hemorrhoids coverage in the wiki. Closes an open item explicitly flagged since Ch1 (concepts/Colorectal Anatomy & Embryology.md had deferred full hemorrhoid pathogenesis/ treatment coverage to "Chapter 11, not yet ingested"). Sections: anatomy and classification (internal grades I–IV, external, strangulated, thrombosed, innervation/continence role — ~20% baseline continence contribution), pathogenesis, clinical presentation (incl. malignancy exclusion — hemorrhoid misattribution as the most common missed CRC-diagnosis opportunity), medical management (stool habits/texture, hygiene, topical/oral incl. phlebotonics), office-based procedures (RBL, IPC, bipolar diathermy, sclerotherapy, thrombosed hemorrhoid excision with its 72-hour timing window), operative management (excisional hemorrhoidectomy — closed Ferguson vs. open Milligan-Morgan vs. abandoned Whitehead — stapled hemorrhoidopexy with its explicit recurrence-vs-pain trade-off against excisional surgery, and Doppler-guided HAL/THD), perioperative pain management (pudendal block, liposomal bupivacaine, narcotic-sparing regimens), hemorrhoidectomy complications (urinary retention, delayed hemorrhage, incontinence, anal stenosis), and special populations (strangulated hemorrhoids, pregnancy, portal hypertension/rectal varices as a distinct non-hemorrhoid entity, Crohn's disease, immunocompromise/HIV).
• Cross-links added (lighter fan-out than Ch9/Ch10, since this is a new page rather than a reconciliation): concepts/Colorectal Anatomy & Embryology.md's Open items note updated to reflect the closed hemorrhoids gap, plus its sources frontmatter extended; concepts/Anorectal Physiology.md gained a note reconciling its ~15%-continence figure with this chapter's ~20% figure (same phenomenon, not a third conflicting number); conditions/Rectal Prolapse (Procidentia).md gained a pointer to this chapter's identical concentric-vs-radial-fold exam distinction; conditions/Fecal Incontinence.md gained pointers to this chapter's hemorrhoidectomy-specific incontinence detail and thrombosed-hemorrhoid pain differential. All four gained [[ASCRS Ch11 - Hemorrhoids]] in frontmatter sources.
• Left one cross-link deliberately incomplete: a Crohn's-specific hemorrhoidectomy caution was not pushed into conditions/Crohn Disease.md, flagged instead as an open item to address once ASCRS Ch47 ("Anorectal Crohn's Disease") is ingested — avoids a premature partial edit to an already large, heavily-sourced page.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the two new pages.
• Next up (pending Stephen's go-ahead): Chapter 12, "Anal Fissure and Anal Stenosis" (PDF p. 240+).

[2026-08-24] ingest | ASCRS Ch12 - Anal Fissure and Anal Stenosis

• Twelfth chapter of the sequential ASCRS ingest, continuing per Stephen's "keep going." Second chapter of Part II ("Anorectal Disease").
• Created sources/ASCRS Ch12 - Anal Fissure and Anal Stenosis.md — citation, scope, key-content pointer for Ch. 12 (Tsikitis & Marecik), PDF pp. 240–257 (single Read call, 18 pages).
• Created two new condition pages rather than one combined page, since fissure and stenosis are distinct clinically-coded entities each warranting independent future cross-links:
• conditions/Anal Fissure.md — definition/presentation/etiology (90% posterior midline; anterior-midline predominance in women; obstetric fissures as a distinct normal/low-pressure subgroup), NOS-deficiency and ischemia (inverse sphincter-pressure/anoderm-perfusion relationship, posterior-midline arteriole paucity) pathophysiology theories, medical treatment ladder (topicals/fiber, topical nitrates, CCBs as first-line for chronic fissures, Botox as second-line with its efficacy-vs-continence trade-off vs. sphincterotomy), operative treatment (obsolete anal dilation, emerging pneumatic balloon dilation, LIS as gold standard — traditional vs. tailored technique, open vs. closed no difference — local advancement flaps as first-line surgery for normotensive/hypotensive fissures, fissurotomy/fissurectomy as non-standard), and atypical/Crohn's/STI fissures.
• conditions/Anal Stenosis.md — types/causes (~90% post-hemorrhoidectomy; anastomotic, IBD, radiation, and other causes), symptoms, evaluation (functional vs. anatomical distinction under anesthesia), Milsom-Mazier classification (severity × location × extent), nonoperative bulking/dilation therapy, a full reconstructive flap ladder (Heineke-Mikulicz transverse closure, rectal advancement, Y-V, V-Y, diamond/rhomboid, house, U/island, rotational S-plasty) with technique selection guidance, Crohn's-specific stenosis outcomes, and hemorrhoidectomy- technique prevention detail.
• Flagged one explicit, unresolved discrepancy rather than silently reconciling it: this chapter describes Crohn's-associated fissures as "deep, painful ulcerations," directly conflicting with the existing Sabiston-sourced characterization on conditions/Crohn Disease.md of Crohn's fissures as "usually lateral, relatively painless, large, and indolent." Noted inline on both Anal Fissure.md and Crohn Disease.md, pending ASCRS Ch47 ("Anorectal Crohn's Disease") as the likely tie-breaker.
• Cross-links added: conditions/Crohn Disease.md gained the discrepancy flag above plus anal-stenosis-in-Crohn's outcome statistics (224-patient and 44-patient cohort data, proctectomy rates) extending its existing brief stenosis mention; conditions/Hemorrhoids.md gained a pointer from its anal-stenosis complication bullet to the new Anal Stenosis.md page's fuller classification/prevention/treatment detail; conditions/Fecal Incontinence.md gained a pointer from its sphincterotomy iatrogenic-cause mention to Anal Fissure.md's specific LIS incontinence rates; procedures/Colonoscopy & Lower GI Endoscopy.md gained pointers from its fissure/stricture exam-contraindication notes to both new pages. All four gained [[ASCRS Ch12 - Anal Fissure and Anal Stenosis]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the three new pages.
• Next up (pending Stephen's go-ahead): Chapter 13, "Cryptoglandular Abscess and Fistula" (PDF p. 258+).

[2026-08-24] ingest | ASCRS Ch13 - Cryptoglandular Abscess and Fistula

• Thirteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Third chapter of Part II ("Anorectal Disease").
• Created sources/ASCRS Ch13 - Cryptoglandular Abscess and Fistula.md — citation, scope, key-content pointer for Ch. 13 (Johnson & Bernier), PDF pp. 258–277 (single Read call, 20 pages).
• Created two new condition pages, mirroring the Ch12 fissure/stenosis split (two stages of one disease process, each warranting independent future cross-links):
• conditions/Anorectal Abscess.md — epidemiology (90% cryptoglandular etiology), cryptoglandular pathophysiology (Eisenhammer's gland theory), classification by anatomic space (perianal 42.7%, ischiorectal 22.7%, intersphincteric 21.4%, supralevator 7.3%, horseshoe as a distinct cross-space pattern), presentation/diagnosis, drainage-route treatment by space/etiology (including the iatrogenic-suprasphincteric-fistula risk of getting supralevator drainage route wrong), post-drainage wound care (no packing), and the controversial/ inconclusive post-drainage antibiotics literature.
• conditions/Anal Fistula.md — the chapter's larger half. Parks classification (subcutaneous/ submucosal, intersphincteric, transsphincteric low/high, suprasphincteric, extrasphincteric), Goodsall's rule and its accuracy limits by fistula type, preoperative imaging modality comparison (MRI as gold standard, EAUS as a cost-effective alternative, CT/fistulography largely surpassed), simple-vs-complex classification (ASCRS SPTF criteria) as the central treatment-strategy fork, fistulotomy as the only recommended option for simple fistulas (concomitant fistulectomy explicitly not recommended), the full seton spectrum (draining, cutting — with its wide 0–67% incontinence range and internal-sphincter-division-not-necessary finding, loose-as-definitive-treatment as an emerging paradigm), fibrin glue and fistula plug as lower-first-line options, endorectal advancement flap and LIFT (plus LIFT variants: BioLIFT, LIFT-PLUG, LIFT plus) as the two accepted first-line complex-fistula techniques (with the Madbouly RCT's initial-vs-1-year success drop as an explicit late-failure caution), and novel therapies (FiLaC, VAAFT, fistulotomy-with-primary-sphincter-reconstruction, stem cell therapy, OTSC Proctology clip) framed as evolving/early-evidence.
• Cross-links added: concepts/Colorectal Anatomy & Embryology.md's Open items note updated to reflect the closed cryptoglandular-abscess/fistula gap (narrowing the remaining item to Hirschsprung's disease only), plus its sources frontmatter extended; conditions/Crohn Disease.md gained a pointer noting Anal Fistula.md explicitly excludes Crohn's/extrasphincteric fistulas from its cryptoglandular treatment ladder and defers to Crohn's-specific management (this page's own content, pending ASCRS Ch47 for full depth); conditions/Fecal Incontinence.md gained a pointer from its fistula-surgery iatrogenic-cause mention to Anal Fistula.md's specific fistulotomy/cutting-seton incontinence rates. All three gained [[ASCRS Ch13 - Cryptoglandular Abscess and Fistula]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the three new pages.
• Next up (pending Stephen's go-ahead): Chapter 14, "Rectourethral and Complex Fistulas" (PDF p. 279+).

[2026-08-24] ingest | ASCRS Ch14 - Rectourethral and Complex Fistulas

• Fourteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "Continue." Fourth chapter of Part II ("Anorectal Disease").
• Created sources/ASCRS Ch14 - Rectourethral and Complex Fistulas.md — citation, scope, key-content pointer for Ch. 14 (Rakinic & Perry), PDF pp. 279–288 (single Read call, 10 pages).
• Created conditions/Rectourethral Fistula.md — a single new page (unlike Ch12/Ch13, this chapter covers one cohesive entity, not two, so no split was needed). The wiki's first content on iatrogenic urologic-colorectal fistulizing disease. Sections: etiology (overwhelmingly iatrogenic — radical prostatectomy 1–6%, radiation with its sharp historical rise in RUF-case involvement, salvage therapy after radiation as the highest-risk group at up to 60%, plus rarer IBD/trauma/elective-surgery causes), presentation (fecaluria/pneumaturia, radiation-associated RUF presenting up to 14 years post-treatment), diagnosis (cystoscopy/colonoscopy, urodynamics as a gate on repair candidacy), classification (Rivera staging vs. the more commonly used simple/ complex schema), multidisciplinary management principles (a meaningful spontaneous-closure rate after diversion alone), and the full repair-approach ladder — transanal ERAF for simple RUF, transperineal dartos/gracilis interposition as the current procedure of choice for complex RUF, posterior York-Mason/Kraske (declining in use), and transabdominal approaches for RUF with concomitant intrapelvic complications — with outcomes data throughout consistently showing radiation as the dominant driver of permanent diversion risk rather than closure-rate failure per se (e.g. one systematic review: 89% vs. 90% healing nonradiated vs. radiated, but 4% vs. 25% permanent fecal diversion and 4% vs. 42% permanent urinary diversion).
• Cross-links added (lighter fan-out, consistent with other genuinely-new single-topic chapters): conditions/Anal Fistula.md gained a pointer noting its ERAF technique description is reused directly by this chapter's simple-RUF repair; conditions/Crohn Disease.md gained this chapter's explicit deferral-to-Crohn's-specific-management note for the rare Crohn's-RUF case; conditions/Rectal Cancer.md gained a pointer for low rectal resection/pelvic radiation as RUF risk factors; concepts/Colorectal Anastomotic Complications.md gained a distinguishing note between its existing chronic-presacral-sinus-tract content and this page's urethral-fistula entity (related radiation/fibrosis mechanism, distinct anatomy and dominant cause). All four gained [[ASCRS Ch14 - Rectourethral and Complex Fistulas]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 15, "Rectovaginal Fistula" (PDF p. 289+) — the anatomically analogous female-specific entity this chapter explicitly flagged as related but separate.

[2026-08-24] ingest | ASCRS Ch15 - Rectovaginal Fistula

• Fifteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Fifth chapter of Part II ("Anorectal Disease") — the female-anatomy analog of Ch14, completing the wiki's coverage of both major acquired complex-fistula entities back-to-back.
• Created sources/ASCRS Ch15 - Rectovaginal Fistula.md — citation, scope, key-content pointer for Ch. 15 (Gurland & Vogel), PDF pp. 289–299 (single Read call, 11 pages).
• Created conditions/Rectovaginal Fistula.md — a single new page (one cohesive entity, like Ch14). Sections: classification (low/high/middle by tract level, simple/complex), symptoms, etiology — obstetric injury (most-cited cause but contribution genuinely hard to pin down across series, 13–24%), Crohn's disease (declining incidence in the biologic era; detailed ACCENT-2 infliximab subset-analysis data — 64% short-term response, no long-term healing benefit over placebo; early stem cell data; generally lower surgical success than non-Crohn's RVF), cryptoglandular, anastomotic/surgical complications (up to 10% of LAR patients — a notable figure worth cross-linking into rectal cancer/anastomotic-complications content), and radiation — evaluation (history, awake/EUA exam, the tampon test, imaging modality comparison), and the full surgical technique ladder: perineal (episioproctotomy, transverse perineal repair), transrectal (ERAF — by far the most common approach in the literature — and rectal sleeve advancement), vaginal, tissue transposition (Martius flap, gracilis interposition), bioprosthetic products (explicitly low success, 20–35%), and abdominal approaches (incl. Turnbull-Cutait delayed coloanal anastomosis). Chapter explicitly notes no technique has been shown superior, and multiple repair attempts are commonly required regardless of approach (mean 3.6 procedures in one series).
• Cross-links added — broader fan-out than Ch14 given RVF's overlap with several already- ingested topics: procedures/Rectal Prolapse Repair.md and procedures/Local Excision of Rectal Neoplasms.md and conditions/Hemorrhoids.md each already had a passing rectovaginal-fistula complication mention (from STARR, anterior local excision, and stapled hemorrhoidopexy respectively) — all three now point to this chapter's fuller RVF content, and this chapter's content corroborates each as a recognized cause; conditions/Rectal Cancer.md and concepts/ Colorectal Anastomotic Complications.md gained the 10%-of-LAR-patients anastomotic-vaginal- fistula figure; conditions/Crohn Disease.md gained a pointer to this page's Crohn's-RVF epidemiology/infliximab content; concepts/Colorectal Anatomy & Embryology.md's Denonvilliers'- fascia/rectovaginal-septum passage gained bidirectional pointers to both this page and Rectourethral Fistula. conditions/Rectourethral Fistula.md's own forward-reference (written during the Ch14 ingest) was updated to point at this now-completed page. All touched pages gained [[ASCRS Ch15 - Rectovaginal Fistula]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 16, "Pilonidal Disease and Hidradenitis Suppurativa" (PDF p. 300+).

[2026-08-24] ingest | ASCRS Ch16 - Pilonidal Disease and Hidradenitis Suppurativa

• Sixteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Sixth chapter of Part II ("Anorectal Disease"). PDF pp. 300–317 (single Read call, 18 pages).
• Created sources/ASCRS Ch16 - Pilonidal Disease and Hidradenitis Suppurativa.md — citation, scope, key-content pointer for Ch. 16 (Bhama & Davis).
• Split into two new pages (chapter covers two genuinely distinct, separately-clinically-coded entities, per this wiki's established split rule — same pattern as Ch12 fissure/stenosis and Ch13 abscess/fistula):
• Created conditions/Pilonidal Disease.md — epidemiology/etiology (acquired-vs-congenital debate, now leaning acquired; "jeep disease" WWII origin), diagnosis (no formal classification system exists), nonsurgical treatment (hygiene/hair removal, phenol 62–95% success, fibrin glue), surgical treatment (I&D, lay open vs. primary closure — Cochrane review of 26 trials/2530 patients favoring off-midline closure — complex flap surgery: Karydakis, Limberg/rhomboid, cleft lift/Bascom, each with conflicting recurrence/morbidity data across series), minimally invasive treatment (VAAPS, laser ablation, trephination), recurrent-disease management (up to 66% at 5 years), wound healing adjuncts.
• Created conditions/Hidradenitis Suppurativa.md — epidemiology/pathogenesis (follicular- occlusion model, Th17/IL-17/IL-1β evidence, smoking/obesity risk factors), clinical presentation/ diagnosis (7.2±8.7-year average diagnostic delay; key differentiators vs. pilonidal disease — absence of midline pits — and vs. Crohn's/anal fistula — absence of anal canal involvement), severity classification (Hurley, Sartorius, HiSCR), treatment ladder (topical clindamycin/ resorcinol, systemic antibiotics — tetracycline, clindamycin+rifampicin — biologics — adalimumab first-line, infliximab second-line, anakinra/ustekinumab, plus biologics-as-surgical-adjunct recurrence-reduction data — other medical therapies incl. metformin, laser therapies, surgery — deroofing, STEEP, wide local excision — with detailed comparative recurrence-rate meta-analysis data: wide excision 13.0%, local incision 22.0%, deroofing 27.0%).
• Cross-link added: conditions/Anal Stenosis.md already named "hidradenitis" in its suppurative- causes differential without a dedicated page to point to — now closed, pointing to both new pages; its Related pages section and frontmatter sources were updated accordingly.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with both new pages.
• Next up (pending Stephen's go-ahead): Chapter 17, "Dermatology and Pruritus Ani" (PDF p. 318+).

[2026-08-24] ingest | ASCRS Ch17 - Dermatology and Pruritus Ani

• Seventeenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Seventh chapter of Part II ("Anorectal Disease"). PDF pp. 318–329 (single Read call, 12 pages).
• Created sources/ASCRS Ch17 - Dermatology and Pruritus Ani.md — citation, scope, key-content pointer for Ch. 17 (Umanskiy & Messaris).
• Created conditions/Pruritus Ani.md — a single new page (one cohesive entity; the chapter's "Dermatology" half is organized as one etiologic category within the pruritus-ani differential, not a separate topic, so no split was needed unlike Ch12/13/16). Sections: pathophysiology (C-fiber- mediated "vicious cycle," histaminergic vs. non-histaminergic itch pathways), etiology (fecal soilage — with manometry/saline-infusion-test data — diet/medications, dermatologic diseases — contact dermatitis, atopic dermatitis, psoriasis, lichen simplex chronicus, lichen sclerosus, seborrheic dermatitis, hidradenitis suppurativa, Bowen's disease, Paget disease, cloacogenic/ anal-margin SCC — infections — fungal, bacterial, parasitic, viral, STI — systemic disease, gynecologic/psychological factors, anorectal disorders), diagnostic approach (history, physical exam, 4-stage clinical staging system, laboratory testing, endoscopy, biopsy), and the two-encounter treatment ladder (first encounter — hygiene/diet/bowel-habit general principles, effective in up to 90% of idiopathic cases; second encounter — topical steroids, systemic antihistamines/ antidepressants, capsaicin, tacrolimus, methylene blue anal tattooing as a last resort).
• Cross-links added — unusually wide fan-out for a single-topic new chapter, given how many already-ingested conditions this chapter's Table 17.1 differential explicitly named: conditions/ Anal Fissure.md, conditions/Hemorrhoids.md, conditions/Anorectal Abscess.md, and conditions/ Anal Fistula.md each gained a Related-pages pointer (all four are named anorectal-disorder pruritus causes); conditions/Hidradenitis Suppurativa.md gained a pointer noting its dermatologic-disorder listing plus this chapter's Hurley-consistent staging summary. All five gained [[ASCRS Ch17 - Dermatology and Pruritus Ani]] in frontmatter sources.
• Forward-reference flagged (not yet linked, pages don't exist): Bowen's disease, Paget disease, cloacogenic carcinoma, and anal-margin SCC as refractory-pruritus differentials — queued for ASCRS Ch19 ("Anal Intraepithelial Neoplasia") and Ch20 ("Anal Cancer") per the boundary map already established in concepts/Colorectal Anatomy & Embryology.md's Open items.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 18, "Sexually Transmitted Infections of the Colon and Rectum" (PDF p. 330+).

[2026-08-24] ingest | ASCRS Ch18 - Sexually Transmitted Infections of the Colon and Rectum

• Eighteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Eighth chapter of Part II ("Anorectal Disease"). PDF pp. 330–349 (single Read call, 20 pages — at the 20-page-per-call cap).
• Created sources/ASCRS Ch18 - Sexually Transmitted Infections of the Colon and Rectum.md — citation, scope, key-content pointer for Ch. 18 (Cowan & Schlussel).
• Created conditions/Anorectal Sexually Transmitted Infections.md — filed as a single comprehensive page rather than split, a new pattern decision this chapter: unlike Ch12/13/16 (genuinely distinct, separately-coded entities arbitrarily paired in one chapter), this chapter's many sub-entities (bacterial, viral, ectoparasitic STIs) share one unifying clinical framework (anorectal-STI presentation, screening/diagnostic algorithm, treatment philosophy per the chapter's own Fig. 18.1 algorithm) — splitting into ~10 per-organism pages would have fragmented content that clinicians actually reason about together. Sections mirror the chapter's own organization: anorectal immunology (HPV increases anal-mucosa Langerhans cells; HIV coinfection dramatically decreases them, worsening HPV persistence/progression — a notable immunologic interaction), screening/prevention (CDC risk-group recommendations, PrEP/PEP dosing and efficacy data, HPV/Hep A/B vaccination, mandatory reporting), diagnosis/evaluation (asymptomatic ~85% of MSM rectal STIs; empiric-treatment algorithm), bacterial STIs (chlamydia incl. serovar D-K vs. L1-L3 distinction, lymphogranuloma venereum — can mimic Crohn's disease, gonorrhea, syphilis — three-stage presentation plus neurosyphilis and the Jarisch-Herxheimer reaction, chancroid, donovanosis), viral STIs (HSV incl. rising HSV-1 anogenital proportion, genital warts/condyloma acuminata incl. HPV 6/11 vs. oncogenic 16/18 subtypes and the full destruction/topical treatment ladder, giant condyloma/Buschke-Löwenstein tumor — up to 56% malignant transformation risk, molluscum contagiosum, HIV incl. detailed HIV-specific anorectal-disease patterns and the HIV-anal-ulcer vs. simple-fissure distinction), and ectoparasitic STIs (pediculosis pubis, scabies incl. crusted/Norwegian scabies in immunocompromised patients).
• Cross-links added — widest fan-out of any single-topic new chapter so far (seven already- ingested pages touched, given how many existing pages had already named HIV, HPV/condyloma, or other STIs in passing): conditions/Pruritus Ani.md (this chapter's content supersedes/expands that page's brief Ch17 "STIs more broadly" subsection), conditions/Anal Fissure.md (fuller HIV-anal-ulcer content extending the existing STI-related-fissures subsection), conditions/Hemorrhoids.md (HIV/immunocompromise hemorrhoidectomy-safety framework — T4-cell count has no predictive value for wound healing, superseding older pre-HAART concerns), conditions/Anorectal Abscess.md and conditions/Anal Fistula.md (HIV-anorectal-disease context — standard-fashion treatment on appropriate HAART), conditions/Anal Stenosis.md (condyloma-excision and STI stenosis causes extended with pointers to the fuller genital-warts/giant-condyloma content), and concepts/Colorectal Anatomy & Embryology.md (HPV 16/18 oncogenic-subtype detail added to the existing anal-transition-zone dysplasia mention, setting up more background for the queued ASCRS Ch19/Ch20 anal-neoplasia chapters). All eight touched pages gained [[ASCRS Ch18 - Sexually Transmitted Infections of the Colon and Rectum]] in frontmatter sources.
• Forward-reference flagged: detailed anal dysplasia/AIN content deliberately kept brief in this chapter and the resulting page — queued for ASCRS Ch19 ("Anal Intraepithelial Neoplasia") and Ch20 ("Anal Cancer").
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 19, "Anal Intraepithelial Neoplasia" (PDF p. 350+).

[2026-08-24] ingest | ASCRS Ch19 - Anal Intraepithelial Neoplasia

• Nineteenth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Ninth and final chapter of Part II ("Anorectal Disease") — Part III ("Malignant Disease") begins immediately after with Ch20 "Anal Cancer." PDF pp. 350–362 (single Read call, 13 pages).
• Created sources/ASCRS Ch19 - Anal Intraepithelial Neoplasia.md — citation, scope, key-content pointer for Ch. 19 (Gaertner & Krane).
• Created conditions/Anal Intraepithelial Neoplasia.md — a single new page (one cohesive premalignant entity, no split needed). Sections: nomenclature (LAST project two-tiered LSIL/HSIL system correlating with AIN-1 vs. AIN-2/3), epidemiology (HPV risk factors, high-risk subtypes 16/18/31/33/35/45 — E6/E7 proteins inhibiting p53/Rb — 79% of anal SCC attributable to type 16/18, HPV vaccine impact on prevalence), incidence/conversion-rate controversy (explicitly flagged: 9-13%/ 5yr AIN-3-to-cancer in some prospective studies vs. 1-in-600-to-4000/yr in a large 2012 meta-analysis — not reconciled, reported as the chapter presents it), screening/surveillance (anal cytology technique and sensitivity/specificity limitations, HRA as likely most clinically useful modality, immunosuppressed-population screening rationale, the not-yet-reported ANCHOR trial), progression biology (extracted largely from cervical-cancer literature — chromosome 3q gain, AIN I→II→III→SCC pathway, unclear whether all steps must be traversed), diagnosis (cytology, biopsy, HRA technique with acetic acid/Lugol's solution), treatment (expectant management; topical therapies — TCA, 5-FU, cidofovir, imiquimod — with detailed response/recurrence data; local ablative therapies — electrocautery, IRC; wide local excision — historically mainstay but no longer recommended given high recurrence/stenosis/incontinence complication rates; treatment-summary algorithm stratified by AIN grade and immune status), and surveillance/prevention (patient compliance flagged as the key factor in reducing progression, not surveillance-program choice; HPV vaccination efficacy data for AIN prevention).
• Cross-links added — closed three previously-flagged forward references: concepts/Colorectal Anatomy & Embryology.md (anal-transition-zone HPV-dysplasia mention updated from "relevant once ingested" to a direct pointer, closing that page's Ch19 forward reference), conditions/Anorectal Sexually Transmitted Infections.md (HPV 16/18 oncogenic-subtype mention and its own Open-items forward reference updated to point at the new page), and conditions/Pruritus Ani.md (Bowen's disease/Paget disease/cloacogenic-carcinoma refractory-pruritus mentions and Open-items forward reference updated similarly). All three touched pages gained [[ASCRS Ch19 - Anal Intraepithelial Neoplasia]] in frontmatter sources; Anal Cancer (Ch20) remains explicitly flagged as still queued in all three.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 20, "Anal Cancer" (PDF p. 363+) — the first chapter of Part III ("Malignant Disease").

[2026-08-24] ingest | ASCRS Ch20 - Anal Cancer

• Twentieth chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." First chapter of Part III ("Malignant Disease"). PDF pp. 363–382 (single Read call, 20 pages, at cap) — Ch20 content itself runs book pp. 357–373 (PDF pp. 363–373); the remaining pages of the same Read call incidentally captured the opening of ASCRS Ch21 ("Presacral Tumors," Kelley & Dozois), not yet reflected on any wiki page.
• Created sources/ASCRS Ch20 - Anal Cancer.md — citation, scope, key-content pointer for Ch. 20 (Sands & Mahmoud).
• Created conditions/Anal Cancer.md — a single new comprehensive condition page, mirroring the chapter's own organization across its several distinct malignancy types (matching the pattern already used for Anorectal Sexually Transmitted Infections and Pruritus Ani rather than splitting into per-histology pages). Sections: epidemiology/risk factors (HIV, immunosuppression, HPV, smoking, anoreceptive intercourse, prior CIN/AIN history — rising incidence ~2.7%/yr); anatomy relevant to staging (anal canal vs. perianal distinction, dentate-line-based lymphatic drainage split — proximal to superior rectal/internal iliac nodes, distal to inguinal/femoral nodes); evaluation and AJCC 8th-edition TNM staging (explicitly distinguished from the existing Colorectal Cancer Staging (TNM) page's colon/rectal-specific schema); perianal SCC (distinct histogenetic origin — CK5/6 & CK13 vs. CK7/18/19 — better prognosis, wide local excision mainstay); anal canal SCC (chemoradiotherapy as primary treatment — Nigro protocol history, ACT I and RTOG 98-11 mitomycin-vs-cisplatin comparisons, capecitabine, cetuximab/EGFR-inhibitor toxicity concerns, RTOG 98-11 radiation protocol, IMRT preference); inguinal lymph node metastases (~13% incidence, FNA use, no surgical excision needed pre-chemoradiation); surgery (local excision for T1N0 only, APR as salvage-only, VRAM flap reconstruction); anal cancer and HIV (NCCN "treat the same" guidance, with the tension against historically-noted tolerability/recurrence concerns explicitly flagged as unresolved); surveillance (ACT II trial's delayed-complete-response data, up to 72% of 11-week non-responders achieving complete response by 26 weeks); anal adenocarcinoma (~20% of anal cancers, staged/treated like rectal cancer, worse survival per a National Cancer Database analysis); verrucous carcinoma/Buschke-Löwenstein tumor (explicitly reconciled against the overlapping content already on Anorectal Sexually Transmitted Infections — same entity, two chapters' framing: Ch18 frames it as an HPV-condyloma-spectrum lesion (up to 56% malignant transformation, wide local excision with 1cm margins), Ch20 frames it as a malignancy with an unresolved benign-vs-SCC-variant classification controversy and a 40–60% transformation rate — figures not reconciled against each other, reported as each source states); melanoma (rare/aggressive, Falch staging classification, BRAF/ c-KIT testing, imatinib for c-KIT+ tumors); perianal Paget disease (closes the Pruritus Ani forward reference — mapping biopsies, wide local excision with frozen-section margin control); basal cell carcinoma (rare, not HPV-associated, local excision); GIST (rare in the anus, ~5% of all GISTs per the chapter — kept brief, deferring to the existing Gastrointestinal Stromal Tumors (GIST) page for the full disease biology rather than duplicating it).
• Cross-links added — closed three previously-flagged forward references: concepts/Colorectal Anatomy & Embryology.md (dentate-line/anal-transition-zone anatomy mention updated to a direct pointer, closing that page's Ch20 forward reference), conditions/Anorectal Sexually Transmitted Infections.md (Giant condyloma/Buschke-Löwenstein section given an explicit reconciliation note pointing at the new page's Verrucous Carcinoma section; Open-items forward reference closed), and conditions/Pruritus Ani.md (Paget disease and Bowen's/cloacogenic-carcinoma mentions updated with pointers to the new page's fuller oncologic-management content; Open-items forward reference closed). Also cross-linked (non-forward-reference): conditions/Anal Intraepithelial Neoplasia.md (AIN as anal SCC's precursor lesion), conditions/Rectal Cancer.md (anal adenocarcinoma staging/ treatment comparison), conditions/Gastrointestinal Stromal Tumors (GIST).md (anal-GIST note added to the intro, pointing back at the new page), and conditions/Anal Stenosis.md (Paget's/Bowen's wide-local-excision stenosis-cause mention given a pointer to the new page's fuller content). All eight touched pages gained [[ASCRS Ch20 - Anal Cancer]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 21, "Presacral Tumors" (Kelley & Dozois, book p. 375+) — its exact PDF start page needs confirming on the next read (opening pages already glimpsed incidentally in this chapter's Read call, but not yet ingested into any wiki page).

[2026-08-24] ingest | ASCRS Ch21 - Presacral Tumors

• Twenty-first chapter of the sequential ASCRS ingest, continuing per Stephen's "continue." Second chapter of Part III ("Malignant Disease"), though most presacral tumors are in fact benign. Book pp. 375–396, captured across two Read calls (PDF pp. 374–393, re-reading the chapter's opening pages that had been incidentally glimpsed during Ch20's read for accuracy; and PDF pp. 394–413, whose tail incidentally captured the opening of ASCRS Ch22, "Sporadic and Inherited Colorectal Cancer," not yet ingested).
• Created sources/ASCRS Ch21 - Presacral Tumors.md — citation, scope, key-content pointer for Ch. 21 (Kelley & Dozois).
• Created conditions/Presacral Tumors.md — a single new comprehensive condition page, mirroring the chapter's own organization across a genuinely heterogeneous set of tumor types unified by one anatomic space and one management framework (matching the pattern already used for Anorectal Sexually Transmitted Infections, Pruritus Ani, and Anal Cancer). Sections: epidemiology/anatomic considerations (rare — as low as 1 in 40,000–60,000 hospital admissions; sacral nerve root function data — bilateral S2–S5 loss causes complete bowel/bladder loss; high sacrectomy pelvic-stability implications); clinical presentation and physical exam (vague pain often misattributed to psychiatric causes, DRE findings, a cited series averaging 4.1 prior misdiagnosis-driven procedures before correct diagnosis); imaging (MRI as gold standard — 50–88% sensitivity/92–97% specificity for benign-vs-malignant differentiation, the "scimitar sign" for anterior sacral meningocele, the Hosseini-Nik algorithmic MR approach); preoperative biopsy (indication-driven, transperineal/parasacral approaches only, meningocele biopsy explicitly contraindicated given meningitis risk); the Mayo classification system (congenital/neurogenic/ osseous/miscellaneous × benign/malignant, reproduced in condensed prose); each major entity (epidermoid/dermoid cysts, tailgut cysts, enterogenous/rectal duplication cysts, teratomas — malignancy risk correlating strongly with age, chordomas — the most common malignant presacral tumor, meningoceles, neurogenic tumors — schwannomas/ependymomas most common, osseous tumors, miscellaneous lesions, Currarino syndrome — HLXB9 gene, sacral malformation/hindgut anomaly/ presacral tumor triad); management (function-sparing for benign vs. en bloc for malignant, decision algorithm, emerging nonoperative-surveillance evidence for small cystic lesions); multidisciplinary team; neoadjuvant therapy (chordomas/chondrosarcomas poorly responsive; Ewing's/osteogenic sarcoma responsive; hormonal therapy for angiomyxomas; immunotherapy promise for chordomas); preoperative considerations; surgical approach by sacral level (posterior vs. abdominal vs. combined based on S3–4 involvement); posterior approach (including the coccygectomy debate — Singer, Mathis, and Messick series data, none showing a clear recurrence benefit from routine coccygectomy); abdominal/combined approach (en bloc principles, middle sacral vessel ligation, VRAM/TRAM/omental/gracilis/gluteus flap reconstruction, posterior sacral transection technique); minimally invasive approaches (Mullaney systematic review — 82 patients, comparable outcomes to open surgery); outcomes (heterogeneous/rare literature, R0 resection with wide margins uniformly associated with lower recurrence, and an extensive chordoma-specific outcomes review — McMaster/SEER, Fuchs/Mayo, Pan/Xiangya/SEER, Kerekes systematic review); and follow-up/ observation-only recommendations.
• Cross-links added (no forward references were pending for this chapter specifically): concepts/Colorectal Anatomy & Embryology.md (presacral-fascia/presacral-space content extended with a pointer to the new page's tumor taxonomy), concepts/Colorectal Anastomotic Complications.md (explicit disambiguation — that page's leak-driven "chronic presacral sinus tract" is a distinct entity from the primary tumors covered on the new page, despite sharing the same anatomic space), conditions/Gastrointestinal Stromal Tumors (GIST).md (presacral/retrorectal GIST noted as a further rare GIST site, distinct from the anal-GIST content added in Ch20), conditions/Anal Cancer.md and conditions/Rectal Cancer.md (both share this chapter's VRAM-flap-reconstruction and chemoradiotherapy-reasoning-by-analogy content). All five touched pages gained [[ASCRS Ch21 - Presacral Tumors]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) with the new page.
• Next up (pending Stephen's go-ahead): Chapter 22, "Sporadic and Inherited Colorectal Cancer: How Epidemiology and Molecular Biology Guide Screening and Treatment" (Glasgow & Hardiman, book p. 397+) — its opening content (sporadic CRC epidemiology/molecular biology, CMS subtypes, right-vs-left CRC, young-onset CRC, Lynch syndrome and variants, FAP and variants, MUTYH-associated polyposis, serrated polyposis syndrome, hamartomatous polyposis syndromes) was incidentally glimpsed in this chapter's second Read call but is not yet ingested into any wiki page — this will need careful reconciliation with the wiki's existing Hereditary Colorectal Cancer Syndromes, Lynch Syndrome, Familial Adenomatous Polyposis (FAP), and Hamartomatous Polyposis Syndromes pages rather than straightforward new-page creation. (Note: on actually reading these pages during the Ch22 ingest, they turned out to be substantive existing pages, not the thin/stub pages speculated above — that characterization was a guess made before opening them, corrected in the next entry.)

[2026-08-24] ingest | ASCRS Ch22 - Sporadic and Inherited Colorectal Cancer

• Twenty-second chapter of the sequential ASCRS ingest (Glasgow & Hardiman), book pp. 397–412 (PDF pp. 402–417), captured across the tail of the Ch21 second Read call (PDF pp. 394–413, book 397–408) and the start of a further Read call (PDF pp. 414–433, book 409–412). Before writing anything, re-read in full the four existing hereditary-syndrome pages this chapter would touch (Hereditary Colorectal Cancer Syndromes, Lynch Syndrome, Familial Adenomatous Polyposis (FAP), Hamartomatous Polyposis Syndromes) — found them to be substantive, detailed pages (sourced from Sabiston Ch52 - Colorectal Neoplasia & Colon Cancer Surgery), not the thin stubs a prior log entry had speculated. Given the heavy overlap, this chapter departs from the wiki's usual one-new-page-per-chapter default: most of its content was reconciled into existing pages as enrichment rather than duplicated as new pages — the first time two consecutive chapters (this one and Ch23) have been handled this way.
• Created sources/ASCRS Ch22 - Sporadic and Inherited Colorectal Cancer.md — citation, scope (sporadic CRC epidemiology/molecular biology/CMS subtypes/right-vs-left/young-onset CRC; Lynch syndrome incl. variants; POLE/POLD1 PPAP; FAP; MUTYH-associated polyposis; serrated polyposis; hamartomatous polyposis syndromes incl. Cowden), and an explicit note on the reconciliation-heavy approach taken.
• Created conditions/Sporadic & Young-Onset Colorectal Cancer.md — a genuinely new topic not previously covered: sporadic-vs-inherited framing, epidemiology, risk factors, right-vs-left CRC biology (CMS distribution, 2018 bevacizumab/cetuximab sidedness study), screening/treatment (FOLFOX), and a dedicated young-onset CRC section (the ACS-vs-NCCN screening-age discrepancy — 45 vs. 50 — flagged explicitly as an unresolved active guideline conflict, not reconciled; management; genetics per Lieu et al.'s TP53/CTNNB1 mutation-rate data).
• Enriched conditions/Lynch Syndrome.md: diagnosis/testing detail (MSI-vs-germline distinction, MMR IHC pattern interpretation with the BRAF V600E discriminator, universal tumor screening, NGS alternative, PREMM5/MMRpro prediction models), a new "Lynch syndrome variants" subsection (Turcot type 1/2, Muir-Torre, familial CRC type X), expanded screening evidence (surveillance-benefit meta-analysis, age-graded risk data, the CAPP2 aspirin chemoprevention trial), expanded surgical management (rectal-cancer/IPAA considerations, guideline recommendations, a registry/meta-analysis showing extended colectomy cuts metachronous CRC risk — 23.5% vs. 6.8%, OR 3.7 — against QoL tradeoffs, subtotal colectomy as an option), and an entirely new "Medical treatment" section (FOLFOX; immunotherapy for MSI-H disease — pembrolizumab/nivolumab/ipilimumab; an ongoing FOLFOX+atezolizumab trial).
• Enriched conditions/Familial Adenomatous Polyposis (FAP).md: new genotype-guided decision-making/outcomes content (severe-genotype 61–74% proctectomy risk, IPAA fecundity/ function/QoL data, IRA pelvic-nerve preservation, registry survival data, and the Lovegrove meta-analysis on mucosectomy vs. stapled IPAA).
• Enriched conditions/Hamartomatous Polyposis Syndromes.md: expanded PJS management (total colectomy+IRA principle, STK11/mTOR-inhibitor chemoprevention note) and an entirely new "Cowden syndrome (CS)" section (PTEN/PHTS, Bannayan-Riley-Ruvalcaba variant, mixed polyp phenotype, 9–16% lifetime CRC risk, surveillance from age 15). Page intro/title updated to reflect three syndromes now covered from two sources.
• Enriched conditions/Hereditary Colorectal Cancer Syndromes.md: two new rows in the "Syndromes at a glance" table (Cowden syndrome, serrated polyposis syndrome) plus a third for the new PPAP section below; an entirely new "POLE/POLD1-related hereditary cancer (PPAP)" section (lifetime CRC risk not well-quantified by the chapter — reported as such rather than estimated).
• Created a new "Serrated polyposis syndrome (SPS)" subsection on conditions/Colorectal Polyps.md (under Serrated polyps) — the other genuinely-new-topic addition from this chapter.
• Enriched concepts/Colorectal Cancer Molecular Pathways.md: new "Clinically relevant mutations: RAS/BRAF and treatment response" section (driver mutations, anti-EGFR resistance, BRAF-inhibitor CRC resistance, intra-tumor heterogeneity); expanded EMT section (ZEB1/ZEB2/TGF-β/ SNAIL/vimentin, ZEB2 as a staging biomarker); expanded CMS section with right/left distribution (CMS1/3 right-sided, CMS2/4 left-sided). Resolved a previously-flagged open item on this page.
• All six touched existing pages plus both new pages gained [[ASCRS Ch22 - Sporadic and Inherited Colorectal Cancer]] in frontmatter sources; all six gained a "Related pages" section where one didn't already exist.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections).
• Chapter 23 was incidentally captured in full during this chapter's second Read call (PDF pp. 414–433) and is documented in the next entry.

[2026-08-24] ingest | ASCRS Ch23 - Management of Malignant Polyps

• Twenty-third chapter of the sequential ASCRS ingest (Yang & Whiteford), book pp. 413–427 (PDF pp. 419–433), captured in full within the same Read call that closed out Ch22 above. A second consecutive reconciliation-heavy chapter: before writing anything, re-read procedures/Endoscopic Polypectomy, EMR & ESD.md in full and found it already had complete Paris/ Kudo/NICE classification and EMR/ESD technique detail (sourced from ASCRS Ch05), including an explicit pre-existing flagged open item about cross-checking against Colorectal Polyps.md's malignant-polyp content.
• Created sources/ASCRS Ch23 - Management of Malignant Polyps.md — citation, scope (adenoma- carcinoma/serrated pathways, malignant polyp definition, Paris/Kudo/NICE lesion assessment, Haggitt/ Kikuchi depth-of-invasion classification and quantitative SMI-depth lymph-node-metastasis risk, histopathological LN-metastasis risk factors, endoscopic resection technique for malignant polyps, TES outcomes, the ACPGBI risk-stratification tool, recurrence/surveillance), and an explicit note on the reconciliation approach taken.
• Reconciled entirely into conditions/Colorectal Polyps.md's existing Malignant polyps section rather than creating a new page — rewrote it into subsections: "Depth of invasion and lymph node metastasis risk" (Haggitt + Kikuchi/Sm plus Kitajima et al.'s quantitative LN-met-risk-by-SMI-depth data: 0% at <1000μm, 3.9% at <2000μm, 17.1% at ≥2000μm for non-pedunculated lesions); "Histopathological risk factors for lymph node metastasis" (a 23-study, 4510-patient systematic review's odds ratios — tumor grade 5.60, LVI 4.81, tumor budding 7.74, SMI>1000μm 3.87 — plus a formal four-criterion curative-resection definition); "Endoscopic resection of malignant polyps" (cross-links to Endoscopic Polypectomy, EMR & ESD.md for technique detail rather than duplicating it; TES data including an explicitly-flagged internally-inconsistent figure — "positive margins (66–93%)" grouped among a sentence otherwise describing "low rates" — reported verbatim per the wiki's flag-don't-fix convention; a North American rectal ESD series: 82.5% en-bloc/74.9% R0/81.8% curative); "Predicting risk of residual disease: the ACPGBI risk-stratification tool" (Table 23.1 reproduced as two markdown tables); "Recurrence and surveillance after endoscopic resection" (ESGE 6-month/JGES 3-year guidance). Added a new "Related pages" section; rewrote Open items/gaps.
• Resolved Endoscopic Polypectomy, EMR & ESD.md's previously-flagged open item (interaction between its ESD/EMR malignancy-risk figures and Colorectal Polyps.md's malignant-polyp content not yet cross-checked) — struck through with a resolved note and a cross-link to the now-expanded section, plus a new Related pages entry.
• Enriched procedures/Local Excision of Rectal Neoplasms.md: new paragraph on TES malignant- polyp outcomes, cross-linking Colorectal Polyps.md and this chapter's source page, including the same flagged margin-status anomaly (hit two Edit-tool errors on this file — a "file not read yet" error, fixed by calling Read first, and then a "string not found" error despite an apparently identical match, fixed by re-anchoring to a smaller, more precisely-bounded snippet).
• All four touched pages gained [[ASCRS Ch23 - Management of Malignant Polyps]] in frontmatter sources.
• Updated sources/Sources.md, conditions/Conditions.md, and index.md (Sources + Conditions sections) — Colorectal Polyps.md's entry rewritten to reflect the expanded malignant-polyp content.
• Next up (pending Stephen's go-ahead): Chapter 24, "Colorectal Cancer: Preoperative Evaluation and Staging" (Hayman & Vasilevsky, book p. 429+) — only its title page has been glimpsed so far (last image in the Ch22/23 Read call), no content read yet.

[2026-08-24] ingest | ASCRS Ch24 - Colorectal Cancer Preoperative Evaluation and Staging

• Twenty-fourth chapter of the sequential ASCRS ingest (Hayman & Vasilevsky), book pp. 429–449 (title page previously glimpsed during the Ch22/23 read; full body/references captured in a further Read call, PDF pp. 434–453). Fifth and final chapter of Part III ("Malignant Disease") in this ingest so far. A large chapter covering CRC screening, colon-vs-rectum delineation, full TNM staging tables, diagnostic workup, imaging, rectal-cancer-specific ERUS/MRI staging, and prognostic factors — before writing anything, re-read Colorectal Cancer Staging (TNM) and Rectal Cancer in full to plan reconciliation, since both already touched on staging (the TNM page only narratively, without actual AJCC tables — a gap it had itself flagged; Rectal Cancer with an explicit open item that MRF/EMVI weren't independently defined anywhere).
• Created sources/ASCRS Ch24 - Colorectal Cancer Preoperative Evaluation and Staging.md — citation, scope, and an explicit note on the reconciliation-vs-new-page split taken.
• Substantially expanded concepts/Colorectal Cancer Staging (TNM).md (rewritten in place) — the chapter's primary home. Added: full AJCC 8th-edition T/N/M category tables and the stage-grouping table (resolving this page's own previously-flagged "actual stage groupings not reproduced" open item); a new "Colon vs. rectum delineation" section (NCCN definition, Table 24.2 criteria, and a third rectal-thirds measurement convention — flagged alongside the two already-noted ones, and notably this one is a discrepancy within the same textbook, ASCRS Ch01 vs. Ch24, not just cross-textbook); a new "Diagnostic workup" section (history, exam, proctoscopy, colonoscopy for synchronous lesions, tumor localization/tattooing incl. its accuracy caveats and implantation-risk case reports, blood work/CEA); a new "Imaging" section (CT chest/abdomen/pelvis, PET-CT); a substantially expanded "Rectal cancer-specific staging modalities" section — ERUS (five-layer anatomy, sm1/sm2/sm3 T1 subdivision, accuracy figures flagged as differing from Colonoscopy & Lower GI Endoscopy.md's ASCRS-Ch04-sourced figures, reported alongside rather than merged) and MRI (protocol, formal CRM definition/accuracy, formal EMVI definition/accuracy, T3a–d subclassification, the MRI-based "Good/Bad/Ugly" risk-stratification framework, pelvic sidewall lymph nodes, restaging MRI performance, and the mrTRG/TRS regression-grading scales); a new "Preoperative evaluation" section (ASCRS rectal cancer checklist, NAPRC); and a new "Prognostic factors" section split into pre-resection pathologic features (LVI, PNI, tumor budding, MMR/MSI — cross-linking rather than duplicating Colorectal Polyps.md's malignant-polyp-specific versions of the same factors), post-resection factors (LN ratio, extranodal tumor deposits, mesorectal grade, tumor regression score), and clinical/imaging factors (age, EMVI, CRM status, tumor location/ sidedness).
• Created concepts/Colorectal Cancer Screening.md — the one genuinely new topic this chapter introduced (average-risk CRC screening: FOBT, FIT, DNA-FIT/Cologuard, flexible sigmoidoscopy, CT colonography, colonoscopy, with the chapter's pros/cons comparison table reproduced), since screening doesn't fit within a staging-focused page.
• Enriched conditions/Rectal Cancer.md: resolved its own previously-flagged open item — MRF/EMVI now have full definitions on Colorectal Cancer Staging (TNM).md, cross-linked in the Staging section and struck through in Open items; extended its rectal-thirds discrepancy blockquote to cover the new third (intra-textbook) convention; added Related pages entries for the newly detailed staging page and the new screening page.
• Light-touch enrichment of procedures/Colonoscopy & Lower GI Endoscopy.md: a cross-link to the new sm1/sm2/sm3 subdivision and the differing ERUS accuracy citation, plus two new Related pages entries — no content duplicated.
• Opportunistic lint fix: conditions/Conditions.md had a stale duplicate bullet for Rectal Cancer left over from when it was first created as a stub (predating this session's compaction) — removed, keeping the accurate, up-to-date bullet; that surviving bullet's wording was also refreshed to mention the newly expanded staging depth.
• All touched/created pages gained [[ASCRS Ch24 - Colorectal Cancer Preoperative Evaluation and Staging]] in frontmatter sources.
• Updated sources/Sources.md, concepts/Concepts.md, conditions/Conditions.md, and index.md (Sources + Concepts sections) with the new/updated pages.
• This closes out Part III ("Malignant Disease") as ingested so far — Chapters 20–24 (Anal Cancer, Presacral Tumors, Sporadic and Inherited CRC, Management of Malignant Polyps, and this chapter) are all now in the wiki.
• Next up (pending Stephen's go-ahead): Chapter 25 — title/scope not yet glimpsed; referenced in passing by this chapter (endoscopic stenting for obstructing tumors, intraoperative tumor localization) as a forward reference, suggesting it may cover colonic stenting or intraoperative localization technique in more depth. To be confirmed once read.

[2026-08-24] ingest | ASCRS Ch25 - Colon Cancer Surgical Treatment

• Twenty-fifth chapter of the sequential ASCRS ingest (Carchman & Kalady), "Colon Cancer Surgical Treatment: Principles of Colectomy," book pp. 451–462 (PDF pp. 455–466), read in the same 20-page call that also captured the start of Chapter 26 (documented separately once that chapter is fully read). Sixth chapter of Part III ("Malignant Disease") — closes out Part III's colon-cancer-surgery coverage before Part III moves fully into rectal-cancer-specific chapters. Before writing anything, re-read procedures/Colon Cancer Resection.md in full — confirmed it already had substantial right/transverse/splenic-flexure/left technique content (from an earlier Sabiston chapter) with an explicit self-flagged open item asking whether complete mesocolic excision (CME) appears elsewhere in the ASCRS textbook. It does, in this chapter — closing that gap became this ingest's main task. Also re-read conditions/Obstructing Colon Cancer.md and conditions/Lynch Syndrome.md's Surgical management section, both of which this chapter also touches, to plan reconciliation vs. new content.
• Created sources/ASCRS Ch25 - Colon Cancer Surgical Treatment.md — citation, scope, and an explicit note on the reconciliation-heavy approach taken (a now-familiar pattern for chapters that land on already-well-covered ground).
• Substantially expanded procedures/Colon Cancer Resection.md (rewritten in place) — the chapter's primary home. Added: a new "Preoperative tumor localization" section (11–21% mislocalization rate on colonoscopy alone, detailed India-ink tattooing technique incl. the submucosal-bleb method and single-distal-tattoo preference, metallic clip + plain-film/CT alternative); elaborated the no-touch-technique paragraph with the actual negative-trial evidence (RCT + CTC blood-sample study); a new "Lymphadenectomy" section (12-node minimum, LNR cross-linked to Colorectal Cancer Staging (TNM).md); an entirely new "Complete mesocolic excision (CME)" section — resolves this page's own previously-flagged open item — covering the TME-analogy rationale, the Bertelsen cohort's 5-year recurrence data (9.7% vs. 17.9%) and lymph node yield data (38 vs. 21), "skip lesion" capture (~5%), and CME's main risk (SMV injury, ~1.6% of right hemicolectomies); a new "Adjacent tissue or organ invasion" section including a new neoadjuvant systemic therapy for locally advanced colon cancer subsection with actual FOxTROT trial data (downstaging, less apical nodal involvement, fewer positive margins, 59% regression rate, NCCN's cT4b recommendation) — this backs a previously-vague FOxTROT mention on Colorectal Cancer Staging (TNM).md; a new "Hepatic flexure colon cancer" subsection (right vs. extended right hemicolectomy, splenic-injury risk data); expanded "Transverse colon tumors" with segmental-transverse-colectomy detail and decision factors; expanded "Splenic flexure tumors" with additional technique detail; two new subsections splitting the prior generic "Left-sided tumors" into "Descending colon cancer" (formal left colectomy) and "Sigmoid colon cancer" (sigmoid colectomy vs. left colectomy, full anterior-resection technique detail); and a new "Special circumstances" section with "Obstructing or perforated colon cancer" (added genuinely new technical detail — mucus fistula construction options, closed-distal-segment handling, subtotal- colectomy indication by proximal-ischemia status — cross-linking rather than duplicating Obstructing Colon Cancer.md's existing condition-focused coverage) and "Surgical resection for colon cancer in the setting of Lynch syndrome" (a brief corroboration of Lynch Syndrome.md's much more detailed existing coverage, same ASCRS guideline citation — cross-linked rather than duplicated). Added a new "Related pages" section; rewrote Open items/gaps (CME gap now struck through and resolved; new gaps added: no RCT for CME, FOxTROT only cited at abstract level).
• Light-touch cross-link added to conditions/Obstructing Colon Cancer.md (new Related pages entry pointing to the new procedural detail on Colon Cancer Resection.md) and to conditions/Lynch Syndrome.md (a corroboration sentence plus a new Related pages entry, both pointing back to Colon Cancer Resection.md's brief mention) — neither page's existing depth was duplicated.
• All touched pages gained [[ASCRS Ch25 - Colon Cancer Surgical Treatment]] in frontmatter sources.
• Updated sources/Sources.md, procedures/Procedures.md, and index.md (Sources + Procedures sections) with the new/updated pages.
• Next up: Chapter 26, "Rectal Cancer: Neoadjuvant Therapy" (Hunt & Mutch) — reading is already in progress (through book p. 469 of an as-yet-undetermined chapter length as of this entry); will be documented as its own ingest entry once fully read, per the one-chapter-at-a-time discipline.

This chapter is the direct specialty-textbook counterpart to Total Neoadjuvant Therapy (TNT) (previously built from a primary-literature review plus the four headline TNT phase III trials — RAPIDO, PRODIGE 23, STELLAR, POLISH II — plus PROSPECT, GRECCAR16, and JANUS), but its focus is different: this chapter covers the history/foundational trials that established preoperative radiotherapy itself, the evidence for concurrent chemoradiation regimens, pCR as an imperfect surrogate endpoint, and — most substantively — induction-vs- consolidation chemotherapy sequencing within TNT regimens, none of which the existing TNT.md page covered.

New source page: sources/ASCRS Ch26 - Rectal Cancer Neoadjuvant Therapy.md.

concepts/Total Neoadjuvant Therapy (TNT).md substantially expanded (full rewrite via targeted section insertions, not a page rewrite): new "History and foundational trials" section (Swedish Rectal Cancer Trial, Dutch Colorectal Cancer Group/TME trial, original Polish trial, Trans-Tasman Radiation Oncology Group trial, Stockholm III, and the Chinese FOWARC trial — none previously ingested; cross-linked rather than duplicated against Rectal Cancer's existing German Rectal Cancer Study mention); new "Concurrent chemoradiation regimen trials" section (Lyon R0-04, CALGB 89901, ECOG 3204, STAR-01, NSABP R-04, German CAO/ARO/AIO-04) — flagged an unresolved cross-trial inconsistency: STAR-01/NSABP R-04 found no DFS benefit (plus added toxicity) from adding oxaliplatin to CRT, while AIO-04 reportedly found a DFS benefit from the same addition, not adjudicated here; new "Pathologic complete response (pCR) as a surrogate endpoint — limitations" section, corroborating/formalizing (not duplicating) the existing pCR/NOM-correlation caveat in the Surgery and NOM section; substantially expanded new "Consolidation vs. induction chemotherapy sequencing" section (Habr-Gama's original/refined regimens, the Timing of Rectal Cancer Response to Chemoradiation Consortium, KONCLUDE, Spanish GCR-3, the MSKCC TNT retrospective cohort ~320 vs ~331 patients, the Rectal Cancer Consortium induction-vs-consolidation trial, German CAO/ARO/AIO-12 — leaning toward consolidation sequencing as the chapter's net takeaway, though not settled to headline-trial evidentiary standard); added a corroboration note to the SCRT Modalities bullet (Washington University pilot, UK phase II study — both new; the chapter's "Polish Colorectal Study Group short-course+FOLFOX vs long-course, 7-year follow-up" comparison is the same trial already ingested as Ciseł 2019 - POLISH II Long-Term Results, treated as corroboration only, not duplicated); updated frontmatter sources and Open items/gaps.

conditions/Rectal Cancer.md lightly edited: "Evolution of treatment" section's German Rectal Cancer Study bullet extended with a one-sentence pointer to TNT.md's new foundational-trials section (not duplicated); Open items/gaps updated; frontmatter sources updated to append [[ASCRS Ch26 - Rectal Cancer Neoadjuvant Therapy]].

Updated concepts/Concepts.md, sources/Sources.md, and index.md (Sources + Concepts sections) with the new/expanded page descriptions. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 146 total files.

Push status: device bridge remained disconnected during this chapter's work (checked twice, consistent with the Ch25 push that is also still pending) — all of the above is staged locally only, not yet pushed to the vault. Next up: Chapter 27, "Rectal Cancer: Local Excision" (Monson & Hoedema) — already fully read (book pp. 479–489); reconciliation planning against Local Excision of Rectal Neoplasms and Colorectal Polyps not yet started.

[2026-08-24] ingest | ASCRS Ch27 - Rectal Cancer Local Excision

Re-read book pp. 479–489 (Monson JRT, Hoedema R) in full (including all three tables and figures) to get exact primary-source figures before writing, given this chapter's density of specific numeric data. Read Local Excision of Rectal Neoplasms and Colorectal Polyps in full beforehand.

New source page: sources/ASCRS Ch27 - Rectal Cancer Local Excision.md.

procedures/Local Excision of Rectal Neoplasms.md substantially expanded: T1N0 criteria/outcomes added to the existing "Surgical (transanal) local excision" section (SEER analysis, two meta-analyses vs. radical surgery, Swedish Rectal Cancer Registry LNM data) plus Kikuchi Sm depth-of-invasion LNM risk (3% SM1 → 23% SM3); new "T2 rectal cancer" section (local excision alone's unacceptable LRR vs. combined with adjuvant/neoadjuvant therapy); new "Complications" section (urinary retention, bleeding, pelvic abscess, defect-closure evidence — genuinely new, not previously covered); new "Oncologic results" section (UK 21-center collaborative margin/LR data, Junginger et al.'s risk-stratified long-term LR/CSS) — resolves this page's own previously-flagged "no primary trial data TEM/TAMIS-vs-TME" open item; new "Adjuvant and neoadjuvant therapy combined with local excision" section (CALGB 8984, a 14-study meta-analysis, Cutting et al.'s systematic review, ACOSOG Z6041, the Lezoche RCT, GRECCAR 2, CARTS — cross-linking Total Neoadjuvant Therapy (TNT) for general regimen detail rather than repeating it); new "Quality of life" and "Salvage surgery" sections (the latter noting salvage outcomes are notably inferior to primary radical surgery — Bikhchandani et al., You et al., Friel et al.); new "Related pages" section; updated Open items/gaps and frontmatter sources.

conditions/Colorectal Polyps.md enriched with more granular nodal-risk data: Chang et al.'s 943-patient cohort (Table 27.1 — LNM rate by LVI/differentiation combination, pT1 and pT2, reused with permission) added under Histopathological risk factors; Hogan et al.'s Table 27.2 (LVI+'s independent association with locoregional vs. systemic recurrence, rectal-cancer-specific: p=0.04 for systemic recurrence, HR 2.57, but not locoregional) added; new "Tumor budding — definition and the ITBCC 2016 consensus" subsection (Hase 1993 origin, formal definition — single cell or cluster of ≤4 cells, hotspot assessment at 0.785mm², all eleven ITBCC 2016 GRADE statements in Table 27.3) substantially expanding the prior brief OR-only mention. Flagged two unresolved cross-source effect-size discrepancies (not reconciled): LVI's odds ratio for LNM (11.5 per Chang et al. vs. 4.81 per the page's existing 23-study systematic review) and poor differentiation's risk ratio (4.9 per a 17-study meta-analysis vs. OR 5.60 per the same existing systematic review) — both point the same direction but differ in magnitude. Updated Related pages, Open items/gaps, and frontmatter sources.

Updated procedures/Procedures.md, conditions/Conditions.md, sources/Sources.md, and index.md (Sources section) with the new/expanded page descriptions. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 147 total files.

Push status: device bridge still disconnected as of this entry — Ch25, Ch26, and now Ch27's work are all staged locally only, not yet pushed to the vault; will push all three chapters' accumulated changes together once connectivity is restored. Next up: finish reading Chapter 28, "Rectal Cancer: Nonoperative Management" (Garcia-Aguilar & Perez) — book pp. 491–508 already read in full (through References); reconciliation planning against Rectal Cancer's existing brief watch-and-wait mention and Total Neoadjuvant Therapy (TNT)'s NOM section not yet started.

[2026-08-24] ingest | ASCRS Ch28 - Rectal Cancer Nonoperative Management

Read book pp. 491–508 (Garcia-Aguilar J, Perez RO) in full, including all tables and figures. No dedicated Watch and Wait/nonoperative-management page previously existed on the wiki — the topic was only touched briefly, in Rectal Cancer's Evolution of treatment section (Habr-Gama origin paragraph, Sabiston-sourced) and Total Neoadjuvant Therapy (TNT)'s Surgery and NOM section (primary-literature-sourced relapse rates and the OPRA trial's TME-free survival data).

New source page: sources/ASCRS Ch28 - Rectal Cancer Nonoperative Management.md.

New concept page created: concepts/Watch and Wait (Nonoperative Management).md — the wiki's first dedicated treatment of this topic. Covers: terminology and definitions (pCR/cCR, local regrowth vs. local recurrence, accidental vs. intentional WW, induction vs. consolidation chemotherapy); rationale (permanent-stoma avoidance, LARS, functional costs of proctectomy); primary tumor assessment/selection criteria (mrCRM/EMVI/N-stage/LPNM indications for nCRT, the MERCURY-trial-based controversy for intermediate-risk disease, early-stage nCRT+LE rationale); tumor location considerations; assessment of tumor response (the three-tier clinical-response classification table, formal cCR criteria across DRE/endoscopy/MRI, Maas et al.'s 98%-accuracy three-modality-combination figure, radiological studies incl. mrTRG/DWI/PET-CT); surveillance/follow-up strategy (3-4mo/6mo/ annual schedule, conditional-survival-based intensity tapering); local regrowth (2-year actuarial rate ~25%, baseline-cT-stage risk-factor data, ~90% R0 salvage-resection rate); systemic recurrences; oncologic outcomes (pooled DFS HR 0.47 favoring proctectomy, no OS difference, explicit discussion of the evidence base's selection-bias limitations); functional outcomes (better QoL/bowel/urinary/ sexual function vs. proctectomy, but 1/3 still have LARS-like symptoms); and tumor-response- prediction research (MSI/K-ras/p53 mutation data, DNA-repair-gene score, patient-derived organoids). Cross-linked into (not duplicating) Total Neoadjuvant Therapy (TNT)'s existing NOM section and Rectal Cancer's Habr-Gama paragraph.

conditions/Rectal Cancer.md lightly edited: Habr-Gama watch-and-wait paragraph extended with a pointer to the new page; resolved the previously-flagged "watch-and-wait protocol specifics not detailed" open item; added a new Related pages entry; updated frontmatter sources.

concepts/Total Neoadjuvant Therapy (TNT).md lightly edited: NOM bullet extended with a pointer to the new page (that section's own primary-literature-sourced relapse-rate figures remain the authority for those specific numbers); updated frontmatter sources.

Updated concepts/Concepts.md, sources/Sources.md, and index.md (Sources + Concepts sections) with the new page and expanded descriptions. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 149 total files.

Push status: device bridge still disconnected as of this entry — Ch25, Ch26, Ch27, and now Ch28's work are all staged locally only, not yet pushed to the vault; will push all four chapters' cumulative changes together once connectivity is restored. This completes the reading and reconciliation of the Chapter 26/27/28 batch that was read ahead earlier in this session. Next up: Chapter 29, "Proctectomy for Rectal Cancer" (Migaly & Weiss) — book pp. 509+ glimpsed only as far as the "Priorities in Proctectomy for Rectal Cancer" section header (through book p. 511); not yet fully read.

[Device reconnected] — pushed the full Ch24–28 backlog to the vault: sources/ASCRS Ch24...md through ...Ch28...md (new), concepts/Colorectal Cancer Screening.md and concepts/Watch and Wait (Nonoperative Management).md (new), plus edits to concepts/Colorectal Cancer Staging (TNM).md, conditions/Rectal Cancer.md, procedures/Colonoscopy & Lower GI Endoscopy.md, concepts/Concepts.md, sources/Sources.md, conditions/Conditions.md, index.md, log.md, procedures/Colon Cancer Resection.md, conditions/Obstructing Colon Cancer.md, conditions/Lynch Syndrome.md, procedures/Procedures.md, concepts/Total Neoadjuvant Therapy (TNT).md, procedures/Local Excision of Rectal Neoplasms.md, conditions/Colorectal Polyps.md — 22 files total, "rejected":[]. All prior chapters' work is now reflected in the live vault, not just the local staging mirror.

[2026-08-25] ingest | ASCRS Ch29 - Proctectomy for Rectal Cancer

Read book pp. 509–527 (Migaly J, Weiss EG) in full, including all figures. Read procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md, procedures/Abdominoperineal Resection (APR).md, conditions/Low Anterior Resection Syndrome (LARS).md, and procedures/Anastomotic Construction.md in full beforehand — all four overlap this chapter heavily.

New source page: sources/ASCRS Ch29 - Proctectomy for Rectal Cancer.md.

procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md substantially expanded (the primary reconciliation target): new "Background" paragraph (historical pelvic-recurrence rates, Heald/Quirke/Martling) plus a new "Anatomy of the rectum and mesorectum" subsection (arterial/venous supply incl. the rarely-identifiable middle rectal artery, formal holy-plane/Denonvilliers'/ Waldeyer's-fascia anatomy, hypogastric/pelvic-splanchnic-nerve course and injury consequences — genuinely new to the wiki); new "Priorities in proctectomy" and "Preoperative preparation" (bowel-prep evidence — VASQIP/NSQIP/Margolin studies) sections; substantially expanded Open LAR technique detail (vascular-ligation-level tradeoffs, splenic flexure mobilization, tumor-specific mesorectal excision for proximal cancers, transanal-division option); new "Anastomosis techniques and low-pelvic reservoir options" section covering all five configurations (straight stapled, handsewn coloanal, J-pouch, end-to-side/Baker, transverse coloplasty) with concrete technique specifics; new "Laparoscopic and robotic LAR" section; taTME section extended with International taTME registry safety data and an 11-study/757-patient meta-analysis — resolves this page's own previously-flagged open item (no primary trial data on taTME oncologic outcomes); entirely new "Multivisceral or extended resections" section (T4b/PRCbTME, pelvic exenteration, sacrectomy); new "Oncologic outcomes" section (worldwide LR now 4–8%, SEER 372,130-patient equivalence analysis, ACOSOG Z6051/ALaCaRT non-inferiority results with reassuring long-term survival equivalence); new "Multidisciplinary rectal cancer care" section (OSTRICH/NCDB data, NAPRC); new Related pages section; updated Open items/gaps and frontmatter sources.

procedures/Abdominoperineal Resection (APR).md enriched: declining-frequency context and explicit "incontinence alone is not an indication for APR" clarification added to Indications; new prone- position perineal-dissection technique paragraph; the wider-excision/ELAPE section extended with a 954-patient nationwide database study finding no benefit to ELAPE over traditional APR for non-circumferential tumors — resolves this page's own previously-flagged open item (no data comparing conventional vs. cylindrical APR); new "Reconstruction after APR" section (66% primary-closure wound-complication rate, flap options, omental pedicle flap); new Related pages section; updated Open items/gaps and frontmatter sources.

conditions/Low Anterior Resection Syndrome (LARS).md substantially expanded: new formal Delphi consensus definition (8 symptoms + 8 consequences) and the LARS score (5-item, 0–42 scale, minor/ major thresholds) plus the BFI alternative — resolves this page's own previously-flagged open item (no LARS score/questionnaire detail); Treatment section expanded into a fuller ladder (dietary fiber 25–35g/day, biofeedback/pelvic floor PT, sacral nerve stimulation with 74% reported success rate, 5-HT3 antagonists/transanal lavage/probiotics); new Related pages section; updated Open items/gaps and frontmatter sources.

procedures/Anastomotic Construction.md lightly edited: its existing Low pelvic anastomosis outcome-comparison content now cross-links to the new construction-technique specifics on the TME page (not duplicated); updated frontmatter sources.

Updated procedures/Procedures.md, conditions/Conditions.md, sources/Sources.md, and index.md (Sources section) with the new/expanded page descriptions. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 150 total files.

Push status: not yet pushed — will push once this chapter's work is confirmed complete. Next up: Chapter 30, "Colorectal Cancer: Postoperative Adjuvant Therapy and Surveillance" (Kleiman & Larson) — already partially read (book pp. 529–539, through the "Abdominal Imaging" surveillance subsection); not yet fully read or ingested.

[2026-08-25] ingest | ASCRS Ch30 - Colorectal Cancer Postoperative Adjuvant Therapy and Surveillance

Read book pp. 529–545 (Kleiman DA, Larson DW) in full, including both tables (30.1 high-risk stage II features, 30.2 high-risk local-excision features) and both surveillance tables (30.3 national- guideline comparison, 30.4 modern-trial comparison). Also finished reading Ch31 in full this session (book pp. 547–559) per the one-chapter-fully-read-before-writing discipline — Ch31 write-up is deferred to a future session. Read conditions/Rectal Cancer.md's existing Survival/surveillance/ adjuvant-chemotherapy section and procedures/Colon Cancer Resection.md's neoadjuvant-colon-cancer section in full beforehand to plan reconciliation boundaries.

New source page: sources/ASCRS Ch30 - Colorectal Cancer Postoperative Adjuvant Therapy and Surveillance.md.

Two substantial new concept pages (the chapter's content was broad enough, and distinct enough from existing pages, to warrant new dedicated homes rather than folding entirely into Rectal Cancer.md):

• concepts/Adjuvant Chemotherapy for Colorectal Cancer.md — NEW. Colon cancer Stage III (5-FU/leucovorin history, MOSAIC/NSABP C-07 FOLFOX data, CAPOX, the IDEA duration collaboration's risk-stratified 3-vs-6-month findings and resulting 2020 NCCN recommendation, with a clarifying note reconciling this chapter's "non-inferiority not proven" framing against Rectal Cancer.md's existing raw-DFS-number framing of the same trial); Stage II (Table 30.1 high-risk features, IMPACT B2/QUASAR/MOSAIC/NSABP-C07 subgroup data, MSI/MMR/BRAF risk stratification, Oncotype DX); radiation for colon cancer (very limited role, NCDB/SEER T4-margin data); neoadjuvant chemo/radiation for colon cancer (cross-linked to Colon Cancer Resection.md as the corroborated, not duplicated, home); rectal cancer's three adjuvant scenarios — following neoadjuvant radiation (ADORE, German CAO/ARO/AIO-04, a ~1200-patient negative meta-analysis), without neoadjuvant radiation (mis-staging risk, two historical RCTs, current NCCN stage-based recommendations), and following local excision (Table 30.2, ACOSOG Z6041 3-year DFS 87%); targeted chemotherapy (AVANT, PETACC-8, N0147 — all negative); molecular profiling (MMR/BRAF, Oncotype DX).
• concepts/Colorectal Cancer Surveillance After Curative Treatment.md — NEW. Rationale and the "recurrence is really detected treatment failure" framing (lead-time/stage-migration bias); Table 30.3 (ASCO/ESMO 2013/ESMO 2017/NCCN colon/NCCN rectum/ASCRS national-guideline comparison); historical trial evidence (8 RCTs, Tjandra & Chan and Pita-Fernandez meta-analyses, FACS trial detail); modern trials (Table 30.4: FACS/GILDA/COLOFOL, plus CEA Watch and the ongoing PRODIGE 13) — collectively showing no significant survival benefit from intensive surveillance; the Alliance/ Commission-on-Cancer NCDB collaboration and other real-world compliance/variability data; specific- test detail (physical exam, CEA, abdominal imaging, colonoscopy incl. metachronous-neoplasia/second- primary rates); special circumstances (Stage I colon — endoscopic-only; Stage I rectal — ERUS/MRI local-surveillance emphasis given 4–33% local-recurrence risk after local excision); quality of life; cost; conclusions.

conditions/Rectal Cancer.md enriched (its existing Survival/surveillance/adjuvant-chemotherapy section is the primary reconciliation target): follow-up paragraph now cross-links to the new Surveillance page (resolves the page's own previously-flagged open item pointing to "the ASCRS Practice Guideline" without further detail); Stage II bullet extended with a pointer to Table 30.1/ BRAF-MMR/Oncotype DX detail; Stage III bullet extended with the 2020 NCCN practical-duration recommendation and a clarifying note on the CAPOX high-risk framing, plus an explicit note that rectal-cancer-specific adjuvant selection is further complicated by neoadjuvant-radiation sequencing (pointing to the new Adjuvant Chemotherapy page's three-scenario breakdown); Related pages and Open items updated (new corroboration note on the IDEA collaboration, still not primary-literature); updated frontmatter sources.

procedures/Colon Cancer Resection.md lightly edited: existing FOxTROT/neoadjuvant-colon-cancer content noted as closely corroborated (not extended) by this chapter; new cross-link to the Adjuvant Chemotherapy page for its genuinely-new postoperative-adjuvant-chemotherapy content (not previously on this procedure-focused page); updated Related pages and frontmatter sources.

procedures/Local Excision of Rectal Neoplasms.md enriched: new Table 30.2 high-risk-feature subsection with current NCCN local-excision-adjuvant recommendations; ACOSOG Z6041 mention extended with this chapter's 3-year DFS figure (87%) — flagged a minor cross-chapter numeric discrepancy (this chapter cites 79 enrolled patients vs. 84 cited by Ch27/this page for the same trial, not adjudicated); updated Related pages and frontmatter sources.

concepts/Total Neoadjuvant Therapy (TNT).md lightly edited: its "Adjuvant therapy after TNT" section extended with a cross-link to the new page's "conventional sequence" adjuvant-chemotherapy detail (ADORE/AIO-04/meta-analysis), tying back to TNT's own treatment-interruption rationale; updated frontmatter sources.

Updated concepts/Concepts.md, sources/Sources.md, and index.md (Sources + Concepts sections) with the new page descriptions. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 153 total files.

Push status: pushed successfully — 11 files (3 new + 8 edited), "rejected":[], confirmed via device_commit_files. Next up: Chapter 31, "Colorectal Cancer: Management of Distant Metastases" (Hedrick TL) — already fully read; not yet written as of this entry (see next log entry).

Re-read book pp. 547–555 (Hedrick TL) in full to capture exact primary data (Fig. 31.1/31.3 algorithms, Table 31.1 modality-comparison table, hazard-ratio predictors of metachronous metastases) before writing, supplementing the prior segment's read of pp. 556–559 (ovarian/brain/adrenal metastases, surveillance, conclusion) — completing the one-chapter-fully-read-before-writing discipline for this chapter.

New source page: sources/ASCRS Ch31 - Colorectal Cancer Management of Distant Metastases.md.

New concept page — the wiki's first dedicated treatment of metastatic-CRC surgical/procedural management (Chapter 31's content was extensive and depth/breadth-wise clearly warranted a new dedicated home rather than folding into Rectal Cancer.md, mirroring the Ch28 Watch-and-Wait and Ch30 Adjuvant-Chemotherapy/Surveillance precedents this session):

• concepts/Management of Colorectal Cancer Distant Metastases.md — NEW. Epidemiology (up to 22% present with mets; liver 75%, lung 22%; 5-yr survival 24–58% with resectable hepatic mets); synchronous metastases (Fig. 31.1 algorithm; primary-tumor management — bleeding, obstruction with stenting-vs-resection-vs-diversion decision factors and the prophylactic-resection philosophical shift, perforation; unresectable-disease chemo-first philosophy with resection-first-vs-chemo-first tradeoffs and the ongoing JCOG1007/CAIRO4/GRECCAR 8 trials; resectable-disease NCCN sequencing vignettes per Fig. 31.3; rectal-cancer-specific radiotherapy-sequencing complexity, incl. a note on watch-and-wait's stage-IV evidence gap); metachronous metastases (site distribution, full hazard-ratio predictor list); liver metastases (Resection — FLR/PVE, staged hepatectomy, ALPPS and the LIGRO trial, laparoscopic-vs-open per OSLO-COMET; Locoregional therapies — full Table 31.1, RFA/MWA mechanism-and-outcome detail, TACE/DEBIRI and Martin et al.'s RCT, TARE/SIRT and the FOXFIRE/SIRFLOX/FOXFIRE-Global pooled analysis, SBRT); lung metastases (STS Expert Consensus Task Force, the ongoing PulMiCC trial, technique and mediastinal-LN-sampling detail); ovarian metastases (Krukenberg-tumor terminology correction, IHC differentiation from primary ovarian cancer, the NCCN move away from prophylactic oophorectomy); brain metastases (SRS replacing WBRT); adrenal metastases; surveillance (borrowing the stage II/III framework from the new Ch30 Surveillance page).

conditions/Rectal Cancer.md lightly enriched: its existing Metastatic disease systemic-chemotherapy-regimen paragraph now cross-links to the new page for the surgical/procedural side (explicitly framed as corroboration, not duplication, of the existing regimen framework); updated Related pages and frontmatter sources.

Updated concepts/Concepts.md, sources/Sources.md, and index.md (Sources + Concepts sections) with the new page description. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 155 total files (153 → 155: one new concept page, one new source page).

Push status: pushed successfully — 7 files (2 new + 5 edited), "rejected":[], confirmed via device_commit_files. Next up: Chapter 32, "Locally Recurrent Rectal Cancer" (Solomon MJ) — begins at book p. 561.

Incidentally read into the start of Ch33 "Appendiceal Neoplasms" (pp. 577–582, through the Neuroendocrine Tumors AJCC staging table) within the same multi-page Read call — Ch33 is not yet fully read and its write-up is deferred.

New source page: sources/ASCRS Ch32 - Locally Recurrent Rectal Cancer.md.

New procedure page — the wiki's first dedicated treatment of LRRC-specific pelvic exenteration (the chapter's content was extensive, technically distinct from primary-tumor exenteration, and depth/breadth-wise warranted a new dedicated home rather than folding into the TME page, mirroring this session's Ch28/Ch30/Ch31 new-page precedents):

• procedures/Pelvic Exenteration for Locally Recurrent Rectal Cancer.md — NEW. Framing (LRRC exenteration as fundamentally distinct from primary-tumor exenteration — extra-mesorectal recurrence planes vs. mesorectal-fascia breach; R0 rates climbing from <50% to ~70% at specialized centers); anatomical classification (Fig. 32.1 five-compartment system); patient selection/treatment planning (imaging — MRI PPV/NPV, MDT assessment and its resectability-determination role, the evolving definition of lateral-compartment resectability with R0-rate trend data, high-vs-low-sacrectomy controversy, metastatic-disease workup cross-linked to the new Ch31 metastases page, neoadjuvant treatment); the three-phase (dissection/resection/reconstruction) technical framework and "6 C philosophy"; preparation/positioning; compartment-specific technique in full detail (central — interlabial radical vaginectomy/perineal urethrectomy; composite pubic bone resection; lateral — en bloc iliac vascular and sciatic/femoral nerve resection; posterior — sacrectomy technique by amputation level, abdomino-lithotomy vs. prone jackknife approach, anterior cortical sacrectomy); reconstruction (urinary conduit options per Fig. 32.14, Boari flap); postoperative management; PelvEx Collaborative outcomes data (R0 55–58%, 5-yr OS 40–50% with clear margins, a note challenging the 1mm-margin R0 definition); conclusions.

procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md lightly edited: its existing brief primary-tumor-exenteration mention (from Ch29) now cross-links to the new page, explicitly distinguishing primary vs. recurrent-disease exenteration; updated Related pages and frontmatter sources.

Updated procedures/Procedures.md, sources/Sources.md, and index.md (Sources + Procedures sections) with the new page description. Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 157 total files (155 → 157: one new procedure page, one new source page).

Chapter 33: Appendiceal Neoplasms (Tan SA, Stocchi L)

Book pp. 577–586 (References end p.586) — read in full (main body pp. 577–582 read incidentally while finishing Ch32's read; completed through References this session).

Reconciliation chapter — no new dedicated page created. The existing conditions/Appendiceal Neoplasms.md (previously sourced from Hoehn 2021 - Appendiceal Neoplasms, a primary-literature review) already covered the same five-subtype framework thoroughly, so this chapter's content was folded in as enrichment rather than duplicated, per the wiki's reconciliation-over-duplication convention.

• sources/ASCRS Ch33 - Appendiceal Neoplasms.md — NEW. Full chapter summary: adenocarcinoma (differential diagnosis, subtypes/staging, resection extent, perforated-tumor management, NCDB adjuvant-chemotherapy data, surveillance); PSOGI mucinous-lesion spectrum (serrated polyp, simple mucocele, LAMN, HAMN, mucinous adenocarcinoma; "volcano sign"; acellular-vs-cellular surveillance-interval stratification; "preemptive" CRS/HIPEC); appendiceal NETs (epidemiology, mesoappendiceal invasion as an added risk feature, Ki-67, AJCC TNM Table 33.1, right hemicolectomy indications, somatostatin analogues, CgA surveillance).
• conditions/Appendiceal Neoplasms.md — enriched: PSOGI classification list extended with the serrated-polyp/simple-mucocele/HAMN entities and the "volcano sign" colonoscopic finding; acellular-vs-cellular mucin passage extended with surveillance-interval stratification and the "preemptive" CRS/HIPEC practice note; NEN management passage extended with mesoappendiceal invasion as an added risk feature and a note on the appendix-specific AJCC TNM schema; colonic-type adenocarcinoma passage extended with perforated-tumor upstaging, NCDB adjuvant-chemotherapy practice pattern, and a cross-link to Colorectal Cancer Surveillance After Curative Treatment for surveillance intervals; Open items updated (two new precision caveats: TNM Table 33.1 detail and NCDB figures not transcribed with hard numbers); frontmatter sources updated; updated: 2026-08-25.
• conditions/Conditions.md, sources/Sources.md, index.md (Sources + Conditions sections) — updated with the enriched page description and new source-chapter entry.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 158 total files (157 → 158: one new source page; no new condition page since this chapter reconciled into the existing one).

Book pp. 587–600 (title page through References) — read in full in the prior turn.

Three distinct sections, three different reconciliation outcomes:

• sources/ASCRS Ch34 - GIST, Neuroendocrine Tumors, and Lymphoma.md — NEW. Full chapter summary across all three sections.
• GISTs — reconciled into the existing conditions/Gastrointestinal Stromal Tumors (GIST).md rather than duplicated: added whole-GI-tract epidemiology restatement (colorectal 5–10% fraction); a new KIT/PDGFRA wild-type molecular subgroup (SDH-deficient GIST, Carney triad, Carney-Stratakis syndrome, NF1-associated GIST); rectal-GIST-specific technique (transanal platforms TEM/TEO/TAMIS, local-excision-vs-radical-resection recurrence-rate comparison); neoadjuvant imatinib per Cavnar et al.'s case series; RFA for limited hepatic metastatic disease; and — extending the existing page's unnamed "multiple randomized trials" reference — four named adjuvant trials (ACOSOG Z9001, EORTC 62024, Scandinavian Sarcoma Group VIII, PERSIST-5). Open items updated; frontmatter sources updated; updated: 2026-08-25.
• Neuroendocrine tumors — general midgut/appendix-excluded NET biology closely corroborated the existing conditions/Small Bowel Neuroendocrine Tumors (NETs).md page (that page's Medical therapy section, backed by PROMID/CLARINET/RADIANT-4/NETTER-1, was not materially extended). The chapter's genuinely new content — a materially different, size-driven colon/rectum-specific staging and treatment algorithm with a much better prognosis than midgut disease — backed a new dedicated page: conditions/Colonic and Rectal Neuroendocrine Tumors.md — NEW. Epidemiology (rectum = most common GI-NET site), carcinoid-syndrome contrast with midgut disease, diagnosis (68Ga-DOTATATE PET/CT 93%/96% sens/spec — noted as closely corroborating, not identical to, the Small Bowel NETs page's 95%/95% figures from a different study; Table 34.3 5-HIAA dietary/medication interferers), site-specific TNM staging (Tables 34.1–34.2), size-driven endoscopic/TES/radical-resection treatment algorithm (Table 34.4/Fig. 34.4, with the 1–2cm zone as a genuine individualized decision point, analogous to but distinct from the appendiceal-NET 1–2cm zone), prognosis (hindgut better than midgut). conditions/Small Bowel Neuroendocrine Tumors (NETs).md lightly edited: intro paragraph now cross-links to the new page, explicitly scoping itself as midgut-focused; frontmatter sources updated.
• Lymphoma — the wiki had no dedicated colorectal-lymphoma page; only a brief small-bowel-focused lymphoma passage existed on conditions/Small Bowel Neoplasms.md, which had explicitly flagged this exact gap as an open item since 2026-08-19. Backs a new dedicated page: conditions/Colorectal Lymphoma.md — NEW, the wiki's first dedicated treatment of this topic. Epidemiology/distribution (<1% of colorectal neoplasms, cecum most common site); WHO histologic subtypes (Table 34.5 — MALT/DLBCL ~45% each, plus follicular/mantle cell/T-cell); diagnosis/staging (Dawson criteria, PET/CT, bone marrow biopsy, modified Ann Arbor staging Table 34.6); treatment (surgery + chemotherapy for localized disease per a 345-patient South Korean retrospective cohort and a 40-patient prospective cohort; R-CHOP; radiation generally avoided given bowel-toxicity risk; special scenarios — perforation at presentation, subacute post-chemotherapy perforation; subtype-specific notes). conditions/Small Bowel Neoplasms.md — its previously-flagged lymphoma open item resolved via strikethrough + note, cross-linking to the new page; frontmatter sources updated.
• conditions/Conditions.md — updated with the three touched/new page descriptions; also fixed a pre-existing duplicate GIST entry (two near-identical bullets for the same page, predating this session's edits) down to one.
• sources/Sources.md, index.md (Sources + Conditions sections) — updated with new page descriptions.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 161 total files (158 → 161: two new condition pages + one new source page).

Push status: pushed successfully — 12 files (4 new + 8 edited: Ch33 + Ch34 combined push), "rejected":[], confirmed via device_commit_files.

Chapter 35: Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (Valente MA, Moran BJ)

Book pp. 605–617 (title page through References) — read in full, opening Part IV.

Reconciliation chapter — no new page created; substantially broadens the existing concepts/Cytoreductive Surgery and HIPEC.md page, resolving its own previously-flagged open item about needing a broader-than-appendiceal (colorectal peritoneal metastases, "CPM") framing.

• sources/ASCRS Ch35 - Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.md — NEW. Full chapter summary: peritoneal disease pathophysiology (PMP, redistribution phenomenon, CPM terminology, dissemination risk factors); PCI (incl. radiological/laparoscopic PCI, PCI-survival correlation, why PCI shouldn't gate PMP candidacy) and CC score (Table 35.1 peritonectomy/organ-resection detail); HIPEC technique and PIPAC; foundational CPM evidence (Verwaal 2003/2008 RCT, Elias 2009 retrospective, corroborating PRODIGE 7 with an updated 42-month median-OS figure); systemic chemotherapy timing (Passot et al.'s response-based prognostic data); prophylactic/proactive CRS-HIPEC strategies (Promenade, HIPECT4, COLOPEC, ProphyloChip/Elias 2011 second-look series); synchronous liver/lung oligometastases; palliative CRS and the "obstruction-free survival" concept.
• concepts/Cytoreductive Surgery and HIPEC.md — substantially enriched: intro reframed around CPM terminology (resolving the previously-flagged open item, marked resolved via strikethrough); new Peritoneal disease pathophysiology section; Scoring systems section extended with full PCI region/scoring detail, radiological/laparoscopic PCI, PCI-survival data, CC-2/CC-3 definitions (previously undefined), and Table 35.1 peritonectomy procedures; new HIPEC technique + PIPAC section; new Foundational CPM evidence base section (Verwaal, Elias, PRODIGE 7 cross-reference); new Systemic chemotherapy timing section; new Prophylactic/proactive CRS-HIPEC section; new Synchronous peritoneal + other-site oligometastases section (cross-linked to Management of Colorectal Cancer Distant Metastases.md, which already had a reciprocal cross-link from the Ch31 write-up); new Palliative CRS section; Open items updated (COLOPEC now independently corroborated with matching detail by Ch35, though still not by primary literature; new items for Verwaal/Elias/Promenade/HIPECT4/ProphyloChip non-ingestion and the oxaliplatin efficacy-vs-toxicity nuance); frontmatter sources updated; updated: 2026-08-25.
• concepts/Concepts.md, sources/Sources.md, index.md (Sources + Concepts sections) — updated with the broadened page description and new source-chapter entry.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 162 total files (161 → 162: one new source page; no new concept page since this chapter reconciled into the existing one).

Push status: pushed successfully — 6 files (1 new + 5 edited), "rejected":[], confirmed via device_commit_files. Next up: Chapter 36 onward.

Chapter 36: Colorectal Cancer: Minimally Invasive Surgery (Spinelli A)

Book pp. 619–642 (title page through References) — read in full. Note: a PDF page-offset drift was discovered starting around this chapter (previous chapters ~pp.547–600 had offset 0; from here the offset drifted +2 to +3, apparently due to unnumbered blank/part-divider pages in the PDF not rendering as separate images). An initial read request for PDF pages "618–635" returned printed pages 621–638, missing the chapter's title page/intro at printed pp.619–620; backfilled with a targeted re-read of PDF pages "614–621" (returning printed 616,617,619,620,621,622,623,624 — page 618 apparently blank/unrendered). From here on, printed page numbers visible in each rendered image are trusted as ground truth over requested PDF page ranges.

Entirely a reconciliation chapter — no new page created. Focused specifically on MIS technique for rectal cancer surgery (the chapter notes colectomy MIS is well-accepted/less controversial and does not cover it further). Substantially corroborates and technically extends the existing Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md and Abdominoperineal Resection (APR).md pages.

• sources/ASCRS Ch36 - Colorectal Cancer Minimally Invasive Surgery.md — NEW. Full chapter summary: history/controversy (port-site recurrence resolution, CLASICC 12% vs. 6% CRM/34% conversion, COREAN, ACOSOG Z6051, ALaCaRT); laparoscopic proctectomy technique (port placement, ICG for real-time ureteral visualization via mono-J stents, "three critical points for colorectal vascular supply" — Griffith's point/right colon/Sudek's point, distal rectal transection limitations, "tennis racket"/"reverse smile" dog-ear-reduction techniques, ICG-FA + the IntAct RCT, air leak testing); laparoscopic APR (Ng et al. RCT — 3.1 vs. 4.1 days bowel function, 4.4 vs. 5.9 days ambulation, $9588 vs. $7517 cost, 213 vs. 163 min OR time, 75% vs. 76% 5-yr survival; CRM data across 19 studies 2–21%; Dutch TME trial APR subset 30% CRM+; robotic APR); robotic rectal cancer surgery (ROLARR RCT — no conversion-rate benefit, no outcome differences, £980 more expensive; hybrid vs. fully robotic); robotic APR/ELAPE; taTME (COLOR III trial, CO2 embolism, multifocal recurrence controversy, a 6-center 3% 2-yr LR study, detailed step-by-step technique incl. purse-string distance rules by tumor-to-ARJ distance); hand-assisted laparoscopic surgery (HALS/HALAR — 11-study summary of 6 findings).
• procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md — enriched: robotic LAR paragraph extended (hybrid vs. fully robotic, ROLARR, disadvantages); new "Technical limitations of distal rectal transection" paragraph; new "Trial evidence" paragraph (CLASICC/COREAN); new "Hand-assisted laparoscopic surgery (HALS)" subsection; taTME section extended with additional safety/terminology detail and a detailed technique paragraph; Oncologic outcomes section extended with CLASICC/COREAN corroboration; Open items updated (CLASICC/COREAN/ ROLARR added to the non-independently-ingested list; IntAct RCT and COLOR III added as new open items); frontmatter sources updated.
• procedures/Abdominoperineal Resection (APR).md — enriched: new "Laparoscopic and robotic APR" section (Ng et al. RCT detail, CRM-reporting gaps, Dutch TME trial 30% CRM+ APR subset, robotic APR/ELAPE, laparoscopic perineal retrograde approach); frontmatter updated (updated → 2026-08-25, Ch36 added to sources); Open items updated.
• procedures/Anastomotic Construction.md — enriched: new "Three critical points for colorectal vascular supply" bullet added to the Mobilization section; Perfusion assessment section extended with the IntAct RCT and ureteral-ICG-visualization detail; frontmatter updated (updated → 2026-08-25, Ch36 added to sources); Open items updated (IntAct RCT note added to the existing ICG open item).
• procedures/Procedures.md, sources/Sources.md, index.md (Sources + Procedures sections) — updated with new source-chapter entry and enrichment notes for the three touched pages.

Chapter 37: Minimally Invasive Complete Mesocolic Excision with Extended Lymphadenectomy for Colon Cancer (Sylla P)

Book pp. 643–662 (title page through References) — read in full. Per the chapter's own framing, this closes out Part III ("Malignant Disease") — note: this conflicts with the Ch35 log entry above, which described Ch35 as opening Part IV ("Benign and Miscellaneous Conditions"). Since Ch36/Ch37 both fall numerically between Ch35 and are malignant-disease-focused in content, one of the two Part-boundary attributions is likely wrong — probably the Ch35 one, given the page-offset/part- divider issue discovered at Ch36 above. Flagged rather than silently corrected in both this log and on the ASCRS Ch37...md source page; doesn't affect any clinical content.

A deep, single-topic dive into complete mesocolic excision (CME) with central vascular ligation (CVL) and Japanese-style D1/D2/D3(/D4) lymphadenectomy for colon cancer, with heavy emphasis on MIS technique and the D2-vs-D3 controversy. Given the depth of terminology, anatomy, and outcomes evidence involved, this backs a new dedicated page rather than simply expanding Colon Cancer Resection.md's existing brief CME section (added by Ch25, which had flagged "no RCT data" as an open item).

• sources/ASCRS Ch37 - Minimally Invasive Complete Mesocolic Excision with Extended Lymphadenectomy for Colon Cancer.md — NEW. Deliberately a structural summary (not a full transcription) pointing to the new dedicated page for full content — covers CME/D1-D2-D3 terminology alignment, anatomical considerations, MIS techniques, quality indicators, outcomes by registry/trial, and conclusions.
• procedures/Complete Mesocolic Excision with D3 Lymphadenectomy.md — NEW, the wiki's first dedicated treatment of this topic and among its most comprehensive single-topic procedure pages. Terminology (CME + CVL = D3 dissection, Hohenberger 2009); full D1/D2/D3/D4 lymph node classification (Table 37.1) plus the alternative JSCCR n(#)(+) location-based classification; decision-making by T-stage (pTis/pT1/cT2/cT3-T4 recommendations with JSCCR registry data); quality indicators of CME resections (mesocolic-plane grading, specimen morphometry Fig. 37.3, comparative NCME/CME+CVL/D3 morphometry data); anatomical considerations for D3 dissection (GCT/GPCT variant percentages, SMV tributary variant percentages, arterial anatomy variant percentages, IMA anatomy); techniques of MIS CME+D3 (right-sided: medial-to-lateral, SMV-first, retrofascial uncinate-first with the full Stefan Benz 9-step protocol and "critical views" 1–8, lateral-to-medial, cranial-to-caudal; left-sided: medial-to-lateral sigmoid approach); short-term outcomes (2019 systematic review, Danish DCCG, JCOG0404, Freund et al. 1.6% vascular injury rate, learning curve/ Melich et al.); laparoscopic-approach subsection (Danish DCCG adoption data, systematic review/ meta-analysis, a large multicenter RCT with 5-yr OS 90.4%/91.8% and DFS 80%/79%, COLD trial interim 100-patient data, Sammour et al.'s USA experience); long-term oncologic outcomes (2019 pooled analysis, Hohenberger 2009 ERCRC registry, updated 1978–2014 ERCRC registry, Danish DCCG population study, cohort studies, an ongoing-trials roundup of COLD/RELARC/SLRC/LCME); central node metastasis oncologic implications subsection (Halsted vs. Fisher models, D3+ metastasis rate data by stage/side, HR 2.29 prognostic significance); rationale for CME adoption (methodological critique of historical-control comparisons, impact on mesocolic dissection grade and lymph node harvest/ skip metastases); conclusions (CME+D2 standard of care, D3 selective use only); Related pages cross-linking to Colon Cancer Resection, Total Mesorectal Excision..., Anastomotic Construction, and Colorectal Cancer Staging (TNM); Open items.
• procedures/Colon Cancer Resection.md — its existing "Complete mesocolic excision (CME)" section now opens with a pointer to the new dedicated page; new Related pages entry added; its "no RCT data on CME vs. standard colectomy" open item resolved via strikethrough, cross-linking to the new page's outcomes data (with a note flagging that this chapter's "standard" resection terminology roughly maps to D2, not D1, in the Japanese framework); frontmatter sources updated.
• procedures/Procedures.md, sources/Sources.md, index.md (Sources + Procedures sections) — updated with new source-chapter and new-page entries.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 165 total files (162 → 165: two new source pages + one new procedure page).

Chapter 38: Colonic Diverticular Disease (Hall JF, Bemelman WA)

Book pp. 665–680 (title page through References) — read in full, across two segments (pp. 665–668 read in an earlier session; pp. 669–680 completed this session, along with a preview into the first few pages of Chapter 39, "Large Bowel Obstruction," Feingold DL/Fleming FJ — not yet ingested).

Entirely a reconciliation chapter — no new page created. Substantially deepens the existing conditions/Diverticulitis.md page (previously built mainly from Sabiston Ch52 - Diverticular Disease, Obstruction & Pseudo-Obstruction plus the SCANDIV/Ladies LOLA/DIVA trial pages) and enriches procedures/Anastomotic Construction.md with diverticular-disease-specific technical detail.

• sources/ASCRS Ch38 - Colonic Diverticular Disease.md — NEW. Structural summary covering epidemiology/pathophysiology/risk factors, diagnostic evaluation, management across the Hinchey spectrum, chronic disease/special populations, fistula, obstruction, and technical aspects of surgery.
• conditions/Diverticulitis.md — substantially enriched: existing Hinchey classification section extended with the modified CT-based Hinchey reclassification (grades 0/1a/1b/2/3/4) and CT-severity- correlates-with-outcome data; new Diagnostic evaluation section (labs, CT/MRI/contrast-enema performance, endoscopic evaluation with complicated-vs-uncomplicated malignancy-yield data); new Complicated diverticulitis section (diverticular abscess management, Hinchey III nonoperative management) inserted ahead of the existing lavage-vs-resection section; lavage-vs-resection section extended with DILALA trial detail (30-day reintervention parity, 45% RRR in 24-month reoperation) and Fig. 38.1 cross-trial comparison, deepening the existing SCANDIV/Ladies discordance discussion into a three-way one; Hartmann's-vs-primary-anastomosis section extended with corroborating cohort data (529 PA/366 HP, mortality 7.9% vs. 19.5%); uncomplicated-diverticulitis section extended with named antibiotics trials (DIABOLO, AVOD — resolving the "no primary trial data" framing into "named but not yet independently ingested"), ambulatory management, and dietary changes; elective-surgery section extended with the DIRECT trial; special populations section extended with corroborating young-patient and immunocompromised-patient data, plus expanded right-sided diverticulitis detail (true vs. false diverticula); new Fistula section (colovesical, colovaginal, colocutaneous) — resolves the page's own previously-flagged colovesical-fistula open item; new Obstruction section — resolves conditions/Large Bowel Obstruction.md's previously-flagged cross-link-to-Diverticulitis open item; new Technical aspects of surgery section (laparoscopic approach evidence, transection margins); new Related pages section; Open items rewritten (several resolved/partially resolved via strikethrough); frontmatter sources updated.
• procedures/Anastomotic Construction.md — enriched: splenic flexure mobilization bullet extended with diverticular-disease-specific SSI-rate evidence (10.6% vs. 8.4%); new "IMA preservation vs. ligation" bullet (distinct from the existing high-vs-low ligation-level content) with RCT/cohort evidence that vessel preservation is non-inferior or superior on leak rate when malignancy isn't suspected; new "Ureteral stents" bullet (routine stenting associated with longer OR time/LOS/cost, selective approach favored); stapled-methods section extended with RCT evidence (145 anastomoses) validating the air-bubble leak test's leak-reduction effect — this page's previously "recommended but not trial-validated" leak-testing note now has outcome-level evidence; new Related pages entry; Open items updated; frontmatter sources updated.
• conditions/Large Bowel Obstruction.md — its previously-flagged cross-link-to-Diverticulitis open item resolved via strikethrough + note; frontmatter sources updated.
• guidelines-trials/SCANDIV Trial.md and guidelines-trials/Ladies Trial (LOLA).md — both updated to note DILALA's headline results are now summarized at the textbook/secondary level on Diverticulitis.md, per this chapter — still not independently ingested from DILALA's own primary publications.
• conditions/Conditions.md, procedures/Procedures.md, sources/Sources.md, index.md (Sources
• Conditions sections) — updated with new source-chapter entry and enrichment notes.

Note: while reading this chapter, previewed the opening pages of Chapter 39 ("Large Bowel Obstruction") through book p. 683 — not counted as read/ingested; full Chapter 39 reading has not yet begun.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 166 total files (165 → 166: one new source page; no new condition/procedure page since this chapter reconciled entirely into existing pages).

Chapter 39: Large Bowel Obstruction (Feingold DL, Fleming FJ)

Book pp. 681–697 (title page through References) — read in full, across two segments (pp. 681–683 previewed while tracking down Ch38's page range in an earlier session; pp. 684–697 completed this session). Chapter flows directly into Chapter 40 ("Lower GI Hemorrhage," Jafari MD/Bleier JIS) — its title page and first page (through p. 700) were also visible in this read but not counted as ingested.

Backs one new dedicated page (Volvulus) and substantially enriches three existing pages (Large Bowel Obstruction, Colonic Pseudo-Obstruction (Ogilvie Syndrome), and Endoscopic Polypectomy, EMR & ESD's colonic stenting section).

• sources/ASCRS Ch39 - Large Bowel Obstruction.md — NEW. Structural summary covering pathophysiology/clinical presentation/imaging, malignant LBO management, volvulus, ACPO, and rare LBO causes.
• conditions/Volvulus.md — NEW, the wiki's first dedicated treatment of volvulus (previously covered only in passing on Large Bowel Obstruction.md). Definition/general epidemiology (sigmoid ~60%/cecal ~40% of cases, risk factors, "volvulus belt" geography); presentation/ diagnosis (coffee bean/bent inner tube/northern exposure/bird's beak/whirl signs); sigmoid volvulus (nonoperative detorsion technique incl. rigid proctoscopy/flexible sigmoidoscopy, success/ recurrence rates, surgery incl. extended-resection indications and gangrenous-segment technique, non-resectional alternatives incl. percutaneous endoscopic colopexy); cecal volvulus (ileocolectomy-first approach, alternatives); cecal bascule; mobile cecum syndrome; ileosigmoid knotting.
• conditions/Large Bowel Obstruction.md — enriched: etiology section extended with a new Rare causes of LBO passage (intussusception, hernia, infection, endometriosis, other malignancies incl. lymphoma); sigmoid/cecal volvulus treatment bullets condensed and redirected to the new dedicated page; malignant-obstruction section substantially extended — obstructing rectal cancer subsection, left-sided obstruction staging-history paragraph (Cochrane-endorsed RCT, Lim on-table-lavage RCT, SCOTIA trial, leak-rate case series, Kube diverting-ileostomy series, ACPGBI audit), right-sided obstruction paragraph (Mege audit), new Unresectable disease bullet; new Related pages section; Open items updated (SEMS RCT item partially resolved via strikethrough, three new items added); frontmatter sources updated.

Chapter 40: Lower GI Hemorrhage (Jafari MD, Bleier JIS)

Book pp. 699–713 (title page through References) — read in full, across two segments (title page/ p.700 previewed while wrapping up Ch39's read in an earlier session; pp. 701–713 completed this session). Chapter flows into Chapter 41 ("Endometriosis," Chua H/Snyder MJ) — its title page and first few pages (through p. 718) were also visible in this read but not counted as ingested; only its brief note on colorectal surgeons' involvement in combined endometriosis procedures was skimmed.

Genuinely new topic for the wiki — no prior page addressed lower GI bleeding as a distinct entity (existing pages mentioned it only in passing, e.g. as a Crohn/UC complication). Backs one substantial new dedicated page.

• sources/ASCRS Ch40 - Lower GI Hemorrhage.md — NEW. Structural summary covering epidemiology/ etiology, presentation/evaluation, risk stratification, management, endoscopic and radiologic evaluation/intervention, recurrent LGIB, small bowel/obscure GIB workup, and surgery.
• conditions/Lower Gastrointestinal Hemorrhage.md — NEW, comprehensive: definition/epidemiology (30-40% of GI bleeds, >200-fold incidence increase >80 vs. 20 years old); full etiology table (diverticulosis/anorectal disease leading, vascular/inflammatory/neoplastic/small-bowel categories); presentation (hematochezia vs. melena logic); evaluation (history/exam focus, initial assessment); risk stratification (shock index, the Oakland score as the only LGIB-specific externally-validated score, BLEED/NOBLADS/Sengupta/Strate scores, an artificial neural network model); management (resuscitation targets extrapolated from upper-GI-bleed literature, anticoagulation reversal incl. DOAC-specific challenges); endoscopic evaluation/intervention (technique, timing evidence, high-risk stigmata, hemostasis modalities by etiology — diverticular bleeding incl. the Strate 847-patient pooled analysis, angioectasia incl. Heyde syndrome, post-polypectomy bleeding); radiologic evaluation (CT angiography, catheter-based angiography incl. embolization technique, nuclear scintigraphy); recurrent LGIB (early/late rebleeding rates, risk factors); small bowel/obscure GIB (capsule endoscopy, double/single balloon enteroscopy, intraoperative enteroscopy); surgery (indications, non-localized-bleeding approach incl. blind subtotal colectomy, segmental vs. subtotal colectomy tradeoffs); Related pages; Open items (flagging the Oakland score, Strate pooled analysis, and colonoscopy-timing RCT as highest-value future primary-literature targets).
• conditions/Diverticulitis.md — new Related pages cross-link to the new LGIB page, distinguishing diverticular bleeding (a distinct presentation) from the inflammatory diverticulitis that page focuses on.
• conditions/Conditions.md, sources/Sources.md, index.md (Sources + Conditions sections) — updated with new source-chapter and new-page entries.

Next up: Chapter 41 ("Endometriosis") — only its opening framing has been previewed; full reading has not begun. Given this chapter's subject matter sits further from this wiki's colorectal- surgery core than prior chapters, its ingestion depth may warrant a lighter touch (structural summary

• cross-link from a colorectal-relevant angle) rather than the full reconciliation treatment — a judgment call to make once the chapter is actually read.

Chapter 41: Endometriosis (Chua H, Snyder MJ)

Book pp. 715–728 (title page through References) — read in full. Judgment call flagged at the end of the Ch40 entry: given this chapter's subject matter (gynecologic disease) sits further from the wiki's colorectal-surgery core than prior chapters, ingestion here is a deliberate lighter touch — a structural summary source page plus one narrow concept page covering only the colorectal-relevant subset — rather than the full reconciliation treatment given to prior chapters.

• sources/ASCRS Ch41 - Endometriosis.md — NEW. Structural summary covering the full chapter (epidemiology, etiology theories, clinical manifestations, diagnosis, r-ASRM/ENZIAN/EFI staging, endometriosis-and-cancer association, medical management, surgical management, recurrence), with an explicit note that the gynecologic-specific material is intentionally not elaborated onto a dedicated wiki page.
• concepts/Colorectal Endometriosis.md — NEW, deliberately narrow: presentation/diagnosis of bowel-involving deep infiltrating endometriosis (cyclical rectal bleeding, dyschezia, limited colonoscopy diagnostic role given extrinsic/submucosal lesions, TVUS "negative sliding sign", rectal EUS/MRI); surgical management (shaving vs. disc excision vs. segmental resection by lesion size/depth, complication rates 2.9–25%, KFSP-type sexual-function comparisons, anastomotic stenosis management post-resection); recurrence (6–67% range, risk factors); Related pages; Open items (flagging the wide complication/recurrence ranges as textbook-level syntheses without primary-study breakdown — highest-value future ingestion target if this topic is revisited).
• conditions/Large Bowel Obstruction.md — one-sentence cross-link added to the existing endometriosis-as-rare-LBO-cause bullet, pointing to the new Colorectal Endometriosis page for diagnosis/technique detail. No frontmatter sources change (link only, no new sourced content).
• procedures/Anastomotic Construction.md — new Related pages entry cross-linking to Colorectal Endometriosis (segmental resection for DIE follows the same anastomotic-technique principles). No frontmatter sources change.

Book pp. 729–742 (title page through References) — read in full, across two segments (pp. 729–734 previewed in an earlier session; pp. 735–742 completed this session). Genuinely new topic for the wiki — no prior page addressed traumatic colorectal injury as a distinct entity. Backs one substantial new dedicated page covering all three anatomic regions the chapter addresses (colon, rectum, anus).

• sources/ASCRS Ch42 - Colorectal Trauma.md — NEW. Structural summary covering colon trauma (epidemiology, AAST grading, diagnosis, management, evidence/guidelines, technical considerations), rectal trauma (epidemiology, diagnosis, AAST grading, anatomic considerations, intraperitoneal/extraperitoneal management, guidelines/outcomes evidence), and anal trauma (epidemiology, diagnosis, management).
• conditions/Colorectal Trauma.md — NEW, comprehensive: historical context (WWI-era mandatory-diversion dogma and its reversal); colon trauma (epidemiology/diagnosis, AAST grading, the RCT evidence base — Stone 1979, Chappuis, Sasaki, Gonzalez, AAST 2001 — that established primary repair as safe, damage control laparotomy evolution incl. Weinberg 2009/Ott 2011/Tatebe 2017, single-vs-double-layer closure technique, Table 42.5 intraoperative decision points); rectal trauma (epidemiology/diagnosis/AAST grading, intraperitoneal-vs-extraperitoneal anatomic divide and management, the "4 Ds" of extraperitoneal management, EAST guidelines, the AAST 2017 758-patient study incl. its 22%-vs-10% diverting-colostomy complication-rate finding and the independent-risk-factor status of distal washout/presacral drainage); anal trauma (epidemiology/diagnosis, minor-injury primary repair, massive blast-injury staged management with vacuum-assisted closure, manometry-guided colostomy reversal, permanent-colostomy criteria); Related pages; Open items (flagging the AAST 2017 study as the highest-value primary-literature target, blunt-trauma diagnosis pathways as underdeveloped, and damage-control-laparotomy technique itself as a natural companion topic for a future dedicated trauma-surgery source).
• procedures/Anastomotic Construction.md — new Related pages cross-link to Colorectal Trauma (single-vs-double-layer closure equivalence, repair-vs-resect-vs-anastomose decision-making). No frontmatter sources change.
• concepts/Anorectal Physiology Testing.md — new Related pages cross-link to Colorectal Trauma (manometry predicting functional outcome before colostomy reversal after sphincter trauma). No frontmatter sources change.
• conditions/Conditions.md, sources/Sources.md, index.md (Sources + Conditions sections) — updated with new source-chapter and new condition-page entries.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 174 total files (172 → 174: one new source page + one new condition page, two cross-link-only edits).

Push status: ~~not yet pushed — device bridge still disconnected (checked again this session, still unreachable). Ch39, Ch40, Ch41, and Ch42's files are all queued together for the next successful connection.~~ Pushed — see the combined Ch39–43 push confirmation at the end of this log. Next up: Chapter 43 ("Inflammatory Bowel Disease: Pathobiology," Shogan BD, Kiran PR) — already read in full this session (book pp. 743–750, title page through References) while finishing the Ch42 PDF read, but not yet written up. Covers host factors (genetics, epigenetics, immunity), intestinal microbiome, environmental factors (urbanization, smoking, NSAIDs, diet), and pouchitis pathobiology. Extensive existing Inflammatory Bowel Disease wiki content already covers clinical/surgical IBD material, so this chapter will need careful reconciliation-vs-new-section judgment rather than a wholesale new page — a call to make when the write-up begins.

Chapter 43: Inflammatory Bowel Disease: Pathobiology (Shogan BD, Kiran PR)

Book pp. 743–750 (title page through References) — read in full in the prior segment (while finishing the Ch42 PDF read), written up this segment. Mainly a reconciliation chapter: extensive existing Inflammatory Bowel Disease wiki content already covers clinical/surgical IBD material, but its "Epidemiology and etiology" section was previously thin (a few bullets); this chapter provides the full host-genetics/immunity/microbiome/environmental-factors pathobiology framework that section was missing.

• sources/ASCRS Ch43 - Inflammatory Bowel Disease Pathobiology.md — NEW. Structural summary covering host factors (genetics, immunity), intestinal microbiome, environmental factors, and pouchitis pathobiology.
• conditions/Inflammatory Bowel Disease.md — substantially expanded: the "Epidemiology and etiology" section (previously ~10 lines) gains four new subsections — Host factors: genetics (population/twin heritability, monogenic early-onset CD, NOD2/IRGM/ATG16L1/IL23R/PTPN2, epigenetics/miRNAs), Host factors: immunity (Th1/Th17/Th2/Th3/Th9/Treg balance, named cytokine roles), Intestinal microbiome (dysbiosis pattern, Table 43.1 candidate organisms, virome/mycobiome, antibiotic-exposure risk data), Environmental factors (urbanization incl. Fig 43.2 data, smoking incl. CYP2A6/GSTP1 genetic modulation, NSAIDs incl. dose-dependence, diet). Frontmatter sources and page-intro updated to reflect the new source and the existing guideline-backed sections further down the page.
• procedures/Ileal Pouch-Anal Anastomosis (IPAA).md — new Pouchitis section added (incidence by UC-vs-FAP indication, IL-1 SNP/NOD2/TLR2-4/defensin genetic-immune associations, fecal-stasis- driven colonic metaplasia, microbiome shift, IL-12/complement transcriptomic signature) — resolves a long-flagged open item (struck through, marked Resolved) that had explicitly called this out as "worth a dedicated source." Frontmatter sources updated.
• conditions/Crohn Disease.md and concepts/Colonic Physiology.md — both existing Bacteroidetes-direction discrepancy blockquotes updated with a note that this chapter independently agrees with the Sabiston/Crohn Disease direction (decreased, not increased) — now 2-against-1 across the wiki's sources, but explicitly not treated as resolved given known cohort/methodology heterogeneity in IBD microbiome literature; the discrepancy itself is left standing per this wiki's flagging convention.
• sources/Sources.md, index.md (Sources section) — updated with the new source-chapter entry. No Conditions.md/Procedures.md/Concepts.md landing-page changes needed (no new pages).

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 175 total files (174 → 175: one new source page; all other changes were enrichments to existing pages).

Push status: ~~not yet pushed — device bridge still disconnected (checked again this session, still unreachable). Ch39 through Ch43's files are all queued together for the next successful connection.~~ Pushed — see the combined Ch39–43 push confirmation at the end of this log. Next up: Chapter 44 ("IBD Diagnosis and Evaluation," Brar MS, MacRae H) — only its opening framing (Key Concepts box, Introduction, start of Clinical Presentation) was visible in this session's read (book p.751); full reading has not begun.

[2026-08-25] push | Combined Ch39–43 push to vault

• Device bridge reconnected. Pushed all queued Chapter 39–43 content in one combined push: 25 files total (9 new, 16 edited), covering sources/ASCRS Ch39 - Large Bowel Obstruction.md, conditions/Volvulus.md, sources/ASCRS Ch40 - Lower GI Hemorrhage.md, conditions/Lower Gastrointestinal Hemorrhage.md, sources/ASCRS Ch41 - Endometriosis.md, concepts/Colorectal Endometriosis.md, sources/ASCRS Ch42 - Colorectal Trauma.md, conditions/Colorectal Trauma.md, sources/ASCRS Ch43 - Inflammatory Bowel Disease Pathobiology.md (all new), plus edits to conditions/Large Bowel Obstruction.md, procedures/Endoscopic Polypectomy, EMR & ESD.md, conditions/Colonic Pseudo-Obstruction (Ogilvie Syndrome).md, conditions/Conditions.md, procedures/Procedures.md, sources/Sources.md, index.md, log.md, conditions/Diverticulitis.md, procedures/Anastomotic Construction.md, concepts/Concepts.md, concepts/Anorectal Physiology Testing.md, conditions/Inflammatory Bowel Disease.md, procedures/Ileal Pouch-Anal Anastomosis (IPAA).md, conditions/Crohn Disease.md, concepts/Colonic Physiology.md.
• Fresh mtimeMs pulled via device_list_dir immediately before the push confirmed the remote vault was still at its post-Ch38 state (last successful push), as expected.
• Push confirmed successful: "rejected":[] across all 25 files.
• The wiki (both local staging copy and the actual vault) is now current through Chapter 43. Next chapter in the sequential ingest is Chapter 44 ("IBD Diagnosis and Evaluation," Brar MS, MacRae H).

[2026-08-25] lint | Full wiki lint pass (post-Ch43)

• First full lint pass since 2026-08-20 (Ch01–Ch43 of the ASCRS textbook ingest had accumulated since then, 175 files total as of this pass — up from 84 at the last lint).
• Frontmatter: 0 bad across all 175 files. The apparent "missing sources" hits from an automated check are false positives — source-type pages legitimately carry sources: [] (they cite the original document itself, not other wiki pages), consistent with established convention. Meta/landing pages (index.md, log.md, Overview.md, Research Priorities.md, and the 5 folder landing pages) still by-design lack a type: field, per the 2026-08-20 pass's ruling.
• Broken wikilinks, fixed — 43 instances across 30 files: a recurring rendering bug (first caught and fixed in the 2026-08-19 lint pass, but not systematically prevented since) where a long [[Page Name]] wikilink gets line-wrapped by an editor and the literal newline lands inside the [[...]] brackets — Obsidian does not resolve a wikilink containing a literal newline. Found and auto-fixed (collapsed each affected link back to a single line, stripping blockquote > continuation markers where present) across index.md, log.md, sources/Sources.md, concepts/Concepts.md, and 26 individual chapter/condition/concept pages (mostly ASCRS Ch11–Ch25 source pages, whose "Related pages"/citation-style backlinks are long enough to wrap). One additional genuine typo fixed by hand: concepts/General Postoperative Complications.md had [[Total Mesorectal Excision (TME) & Sphincter-Sparing Resection)]] — a stray trailing ) inside the brackets — corrected to the valid page name.
• Orphan pages: none. Every entity page has at least one inbound wikilink.
• Landing-page and index.md completeness: no gaps. Every file in each category folder is listed on both its folder landing page and index.md. (Ladies Trial (LOLA).md doesn't appear by its literal filename on either list, but resolves correctly via its aliases: ["Ladies Trial", "LADIES Trial"] frontmatter, as previously confirmed in the 2026-08-19 pass — not a gap.)
• Related-pages cross-link symmetry: checked all 55 pages with a "Related pages" section against their targets; found 81 one-directional links (page A points to B, but B has no link back to A anywhere in its content). Given the volume and that this wiki has never enforced full bidirectional symmetry as a hard rule (only a small number of clearly-missing reciprocal links were fixed in the 2026-08-19 pass), not treated as a defect requiring mass fixes — noted here for visibility rather than acted on. Flagging to Stephen if he wants a follow-up pass dedicated to this.
• Staleness sweep: grepped for "not yet ingested" / "no dedicated page" / "worth a dedicated source" and similar phrasing across all pages; spot-checked each hit against current wiki state. No stale claims found — all such notes either describe still-accurate open items or historically accurate statements about state at time of writing (several already correctly struck through and marked Resolved by later chapters, e.g. IPAA's pouchitis gap resolved by Ch43).
• Research Priorities.md — last swept 2026-08-19, before the entire Ch01–Ch43 ASCRS ingest. Its own text already disclaims exhaustiveness ("a sweep of explicit Open items notes, not a literature search... re-sweep periodically"). Not re-swept in this pass (a full re-sweep of 175 pages' Open items is a larger, separate undertaking) — flagged as due for a refresh whenever Stephen wants one, not treated as a lint defect.
• All fixes applied directly (no "apply all" prompt needed — same low-risk, mechanical-fix pattern as prior lint passes). Frontmatter and wikilink checks re-run clean after fixes: 175 files, 0 bad frontmatter, 0 broken/newline-embedded wikilinks, 0 orphans.

Chapter 44: IBD Diagnosis and Evaluation (Brar MS, MacRae H)

Book pp. 751–764 (title page through References), read in full this session. Another mainly-reconciliation chapter, like Ch43: extensive existing Inflammatory Bowel Disease, Crohn Disease, and Ulcerative Colitis content already covers clinical/surgical IBD material, but diagnostic workup detail (labs, imaging, endoscopy, histology, classification/scoring systems, CRC surveillance) was thinner across all three pages. Two genuinely new-to-the-wiki additions: a full endoscopic/clinical activity-scoring suite and a risk-stratified colorectal cancer surveillance framework — neither existed anywhere in the wiki before this chapter.

• sources/ASCRS Ch44 - IBD Diagnosis and Evaluation.md — NEW. Structural summary covering IBD phenotypes/Crohn's-vs-UC distinguishing features (Table 44.1), IBD-U/indeterminate colitis, PSC-IBD, extraintestinal manifestations (Table 44.2), diagnostic evaluation (labs/imaging/ endoscopy), histology (Tables 44.3/44.4), genetic studies, classification/grading (Tables 44.5/ 44.6), endoscopic scores (Tables 44.7–44.9), activity scores (Table 44.10), and surveillance endoscopy (Table 44.11, SCENIC terminology).
• conditions/Inflammatory Bowel Disease.md — edited in five steps: (1) frontmatter sources gained Ch44; (2) "Classification" section extended with Montreal E1–E3/S0–S3 + Paris/PUCAI detail for UC and a Paris-classification cross-link for Crohn's; (3) "Extraintestinal manifestations" gained an EIM-activity association framework (Table 44.2) and a non-EIM manifestations bullet (anemia, osteopenia, cholelithiasis, nephrolithiasis, tubulointerstitial nephritis, VTE); (4) a large insertion between the IBD-U paragraph and "Medical treatment" adding extended IBD-U/PSC-IBD detail, a distinguishing-features paragraph, and new laboratory/imaging/endoscopy/genetic-studies paragraphs, plus two brand-new top-level sections — "Endoscopic and clinical activity scoring systems" and "Colorectal cancer surveillance in IBD"; (5) the "Symptom severity assessment" paragraph in "Medical treatment" trimmed to cross-reference the new scoring section instead of duplicating it, and "Open items / gaps" updated with a new bullet summarizing what Ch44 closed.
• conditions/Crohn Disease.md — frontmatter sources gained Ch44. Montreal classification section extended with the Paris pediatric classification (A1a/A1b age split, L4a/L4b upper-GI subdivision, G0/G1 growth-delay modifier). Post-surgical recurrence-prevention paragraph gained full Rutgeerts score grading detail (i0–i4). Diagnosis section gained the pANCA+ASCA 70%/93% combo stat, SES-CD's four graded domains, an MRE multicenter-accuracy note, transperineal/transanal ultrasound and MR pelvis for perianal disease, and the 64–74% pathologist UC-vs-CD histologic-accuracy caveat. NUDT15 added as a second pre-thiopurine pharmacogenomic test alongside the existing TPMT mention. "Open items / gaps" gained a new bullet summarizing the Ch44 additions.
• conditions/Ulcerative Colitis.md — frontmatter sources gained Ch44. "Disease severity and monitoring" section gained full Mayo endoscopic subscore grading detail (0–3) plus a cross-link to Inflammatory Bowel Disease's new scoring-systems section and to its Montreal/Paris classification detail (avoiding duplication). "Indications for surgery" section's surveillance- colonoscopy bullet now points to Inflammatory Bowel Disease's new "Colorectal cancer surveillance in IBD" section for the full risk-stratified framework rather than duplicating it. "Open items / gaps" updated: the chromoendoscopy-vs-standard-definition question noted as partially answered by Ch44's cited RCTs (still textbook-level citation); the long-standing pouchitis gap struck through and marked Resolved (already closed by Ch43's IPAA.md Pouchitis section, but this page's own open-item note had not yet been updated to reflect that).
• sources/Sources.md, index.md (Sources section) — updated with the new source-chapter entry. No Conditions.md/Procedures.md/Concepts.md landing-page changes needed (no new condition/ procedure/concept pages created).

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 176 total files (175 → 176: one new source page; all other changes were enrichments to existing pages). Wikilink resolution re-checked (pipe-aware, alias-aware, newline-detecting) — one newline-embedded wikilink self-introduced during this chapter's write-up caught and fixed immediately; 0 broken links remain (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — device bridge connected briefly (confirmed wiki root state) then dropped mid-push before file transfer began; Ch44's files are queued for the next successful connection alongside Ch45 below. Stephen asked to continue the ingest locally in the meantime.~~ Pushed — see the combined Ch44–47 push confirmation at the end of this log. Next up: Chapter 45 ("Medical Management of Ulcerative Colitis," Lightner AL, Strong SA) — its opening framing was visible during this chapter's PDF read but not yet ingested; likely a significant reconciliation target against Ulcerative Colitis's existing ACG/AGA/BSG-guideline- sourced medical management section.

Chapter 45: Medical Management of Ulcerative Colitis (Lightner AL, Strong SA)

Book pp. 765–779 (title page through References), read in full this session. Heavily overlapping with Ulcerative Colitis's existing ACG 2025/AGA 2024-guideline-sourced medical management section — most of the advanced-therapy roster, the VARSITY head-to-head data, and the ASUC escalation algorithm were already present nearly verbatim. Genuinely new material: homeopathic/ adjunct agents, drug-mechanism/formulation detail, concrete pivotal-trial dosing/response tables, a dedicated maintenance-of-remission framework, and CONSTRUCT-trial/biosimilar rescue-therapy detail.

• sources/ASCRS Ch45 - Medical Management of Ulcerative Colitis.md — NEW. Structural summary covering homeopathic agents (curcumin, probiotics), 5-ASA mechanism/formulation, glucocorticoids, immunomodulators, JAK inhibitors, biologics/biosimilars (incl. Tables 45.4/45.5 pivotal-trial data), disease severity (Truelove and Witts Table 45.1, Mayo score Table 45.2), induction of remission, severe/fulminant disease (ASUC), and maintenance of remission.
• conditions/Ulcerative Colitis.md — frontmatter sources gained Ch45. Edited in six places: (1) "Disease severity and monitoring" gained Truelove and Witts criteria detail and Mayo score domain detail (Tables 45.1/45.2); (2) "Mildly to moderately active UC" gained 5-ASA mechanism (PPAR-γ) and sulfasalazine-vs-mesalamine side-effect detail, budesonide MMX formulation/dosing detail, and curcumin as a new adjunct-therapy topic; (3) the advanced-therapy roster table gained a new "Pivotal trial dosing and response rates" table (Tables 45.4–45.5) with concrete per-agent induction/maintenance numbers; (4) the ASUC section gained cyclosporine dosing refinement (2 mg/kg/day now the recommended dose per RCT evidence), the CONSTRUCT trial, and CT-P13 biosimilar rescue-therapy data; (5) a new "Maintenance of remission" top-level section added — who needs ongoing therapy, drug-by-drug maintenance evidence including MERIT-UC's negative methotrexate result, and biosimilar-switching studies; (6) "Open items / gaps" gained a new bullet summarizing the Ch45 additions and noting VARSITY is now independently cited by three secondary sources with identical numbers.
• Research Priorities.md — VARSITY entry updated to note the third independent secondary citation (Ch45) with matching numbers; still flagged as not independently primary-sourced.
• sources/Sources.md, index.md (Sources section) — updated with the new source-chapter entry. No Conditions.md/Procedures.md/Concepts.md landing-page changes needed (no new pages).

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 177 total files (176 → 177: one new source page; all other changes were enrichments to existing pages). Wikilink resolution re-checked (pipe-aware, alias-aware, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally per Stephen's instruction while the device bridge is unreliable; Ch44 and Ch45's files are both queued for the next successful connection.~~ Pushed — see the combined Ch44–47 push confirmation at the end of this log. Next up: Chapter 46 ("Medical Therapy for Crohn's Disease," Smith RK, Holubar SD) — its opening framing (AGA/ACG/ECCO Crohn's guideline summary Table 46.1, high-risk-feature Table 46.2) was visible during this chapter's PDF read but not yet ingested; likely another significant reconciliation target, this time against Crohn Disease's existing BSG 2025-guideline-sourced advanced-therapy section — worth checking for agreement/disagreement given three different Crohn's-specific guidelines (AGA, ACG, ECCO) are named vs. the wiki's current single-guideline (BSG) basis.

Chapter 46: Medical Therapy for Crohn's Disease (Smith RK, Holubar SD)

Book pp. 781–798 (title page through References), read in full this session. Substantial overlap with Crohn Disease's existing BSG 2025-guideline-sourced "Advanced therapy, monitoring, and post-surgical management" section, but adds real primary-trial-level detail that section didn't have — named trials for combination therapy, a treat-to-target framework, three TDM trials with genuinely conflicting results, biosimilar data, and postoperative-recurrence risk factors. Also covers microbiome-directed therapies essentially absent from the wiki until now, plus a notable patient-safety flag (2020 FDA fecal-transplant safety alert) and a new thiopurine-safety consideration (EBV-positive young men's hepatocellular T-cell lymphoma risk).

• sources/ASCRS Ch46 - Medical Therapy for Crohn's Disease.md — NEW. Structural summary covering microbiome therapies (antibiotics, probiotics, diet, fecal transplant, EEN), 5-ASA therapy, corticosteroids (Tables 46.3–46.6), immunomodulators (thiopurine pharmacokinetics/TPMT distribution, Table 46.7, methotrexate Table 46.8), biologic therapy (Table 46.9 dosing, combination-therapy trials, leukocyte-trafficking agents, biosimilars), and induction/maintenance principles (treat-to-target/STRIDE/CALM, TDM trials, de-escalation, postoperative prophylaxis).
• conditions/Crohn Disease.md — frontmatter sources gained Ch46. Edited in seven places: (1) Aminosalicylates bullet gained a mechanistic caveat (mucosal vs. full-thickness disease), NCCDS/ECCDS trial mention, and Crohn's-proctitis rectal-5-ASA dosing; (2) Corticosteroids bullet gained the budesonide "open-capsule technique," toxicity-table summary, and practical tapering detail; (3) Immunosuppressive-agents bullet gained TPMT genotype-distribution numbers (80%/10%/ 10%/0.3%), a new EBV-positive-young-men hepatocellular T-cell lymphoma safety flag, and methotrexate side-effect detail by organ system; (4) Anti-TNF bullet gained certolizumab/ adalimumab dosing specifics; (5) Novel-therapies bullet gained natalizumab's quantified PML risk (1 in 100 JC-virus-antibody-positive patients); (6) a new "Microbiome therapies, treat-to-target, and trial-level nuance" top-level subsection added — microbiome-directed therapies (incl. the FMT safety alert), named combination-therapy trials (SONIC, REACT, DIAMOND), the STRIDE/CALM treat-to-target framework, three TDM trials with conflicting results (TAXIT, TAILORIX, PAILOT), and biosimilar non-inferiority data; the existing "Post-surgical recurrence prevention" and "Withdrawal of therapy" bullets were extended with margin/plexitis recurrence-risk-factor data and the Fig. 46.3 de-escalation framework, respectively; (7) "Open items / gaps" gained a new bullet summarizing the Ch46 additions and flagging the TDM/combination-therapy evidence tensions as genuinely unresolved rather than reconciled.
• Research Priorities.md — the Crohn's-specific ACG/AGA guideline gap bullets updated to note Ch46 supplies a secondary AGA/ACG/ECCO comparison table, which doesn't close the primary-ingestion gap.
• sources/Sources.md, index.md (Sources section) — updated with the new source-chapter entry. No Conditions.md/Procedures.md/Concepts.md landing-page changes needed (no new pages).

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 178 total files (177 → 178: one new source page; all other changes were enrichments to existing pages). Wikilink resolution re-checked (pipe-aware, alias-aware, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally per Stephen's instruction; Ch44, Ch45, and Ch46's files are all queued for the next successful device-bridge connection.~~ Pushed — see the combined Ch44–47 push confirmation at the end of this log. Next up: Chapter 47 ("Anorectal Crohn's Disease," Steinhagen E, Bafford AC) — its opening framing (fistulizing-complications epidemiology, general management principles) was visible during this chapter's PDF read but not yet ingested; likely a substantial reconciliation target against Crohn Disease's existing perianal-disease content and the ASCRS Ch13/Ch14/Ch15 fistula pages.

Chapter 47: Anorectal Crohn's Disease (Steinhagen E, Bafford AC)

Book pp. 799–812 (title page through References), read in full this session. Supplies the full perianal-Crohn's treatment that Anal Fistula (ASCRS Ch13) had explicitly deferred as "still-pending" when it was ingested. Substantial new content: pathogenesis, Parks/AGA fistula classification, imaging-modality diagnostic accuracy, concrete RCT-level biologic data for fistulizing disease, surgical technique outcomes, a much stronger mesenchymal-stem-cell-therapy trial, and non-fistulizing complications (fissures, skin tags, hemorrhoids, stricture, cancer) essentially uncovered in the wiki before now.

• sources/ASCRS Ch47 - Anorectal Crohn's Disease.md — NEW. Structural summary covering epidemiology/pathogenesis, abscess, fistula classification, diagnosis, medical management, surgical management, rectovaginal fistula, non-fistulizing complications, and diversion/ proctectomy.
• conditions/Crohn Disease.md — frontmatter sources gained Ch47. Trimmed the existing "Perianal disease" mention in "Clinical manifestations" to a brief pointer (removing an awkward pre-existing grammatical merge and the now-outdated "still-pending ASCRS Ch47" note), then added a large new top-level "## Perianal (anorectal) Crohn's disease" section (inserted before "Prognosis") covering epidemiology/pathogenesis, abscess, fistula classification, diagnosis, medical management (concrete ACCENT II/CHARM/PRECiSE/GEMINI 2 numbers), surgical management (fistulotomy, seton, endorectal advancement flap, LIFT, fibrin glue/plugs, mesenchymal stem cell therapy), rectovaginal fistula in CD, non-fistulizing complications, and diversion/proctectomy. Flagged a new discrepancy (not resolved): this chapter's positive 212-patient phase 3 mesenchymal-stem-cell trial vs. an existing BSG-sourced bullet citing a failed phase III trial of the same drug class (Cx601/darvadstrocel) — cross-referenced in both directions. Extended the existing Crohn's-fissure pain-characterization discrepancy with Anal Fissure with an Update note (Ch47 sides with Ch12's "painful" characterization, now 2-against-1 against the Sabiston-sourced "relatively painless" text). "Open items / gaps" gained a new summary bullet.
• conditions/Rectovaginal Fistula.md — frontmatter sources gained Ch47. The existing 10-patient uncontrolled stem-cell series bullet extended with Ch47's much stronger phase 3 RCT data (212 patients, 56.3% vs. 38.6%) and a separate RVF-specific stem-cell RCT (51% vs. 35%), cross- referencing the same stem-cell-trial discrepancy flagged on Crohn Disease. "Open items / gaps" gained a new bullet.
• conditions/Anal Fistula.md — the "still-pending ASCRS Ch47" open item struck through and marked Resolved, pointing to Crohn Disease's new section.
• conditions/Anal Stenosis.md — the "still-pending ASCRS Ch47" open item struck through and marked Partially resolved (Ch47's own anal-stricture figures are now on Crohn Disease, but this page's specific cohort figures from ASCRS Ch12 weren't separately cross-posted).
• conditions/Hemorrhoids.md — the "still-pending ASCRS Ch47" open item struck through and marked Resolved.
• conditions/Anal Fissure.md — the Crohn's-fissure pain-characterization discrepancy blockquote extended with an Update note (see above); the matching "still-pending ASCRS Ch47" open item struck through and marked Partially addressed (Ch47 sides with this page against Sabiston, but the underlying contradiction remains unresolved).
• sources/Sources.md, index.md (Sources section) — updated with the new source-chapter entry. No Conditions.md/Procedures.md/Concepts.md landing-page changes needed (no new pages).

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 179 total files (178 → 179: one new source page; all other changes were enrichments to existing pages). Wikilink resolution re-checked (pipe-aware, alias-aware, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally per Stephen's instruction; Ch44 through Ch47's files are all queued for the next successful device-bridge connection.~~ Pushed — see the combined Ch44–47 push confirmation at the end of this log.

• The wiki (both local staging copy and the actual vault) is now current through Chapter 47. Next chapter in the sequential ingest is Chapter 48 ("Crohn's Disease: Surgical Management," Cannon LM, Fichera A).

Next up: Chapter 48 ("Crohn's Disease: Surgical Management," Cannon LM, Fichera A) — its opening framing (declining surgery rates over decades, Table 48.1 operative indications, bowel obstruction fibrosis-vs-inflammation imaging distinction, balloon dilation outcomes, penetrating disease/abscess management) was visible during this chapter's PDF read but not yet ingested; likely a significant reconciliation target against Crohn Disease's existing surgical-treatment sections, which currently source from the older Sabiston textbook chapters.

[2026-08-25] Chapter 48 — Crohn's Disease: Surgical Management

Read in full (book pages 813-830, PDF pages 806-823) before writing. A general Crohn's surgical- management chapter (Cannon LM, Fichera A) — as anticipated in the prior entry, this was a heavy reconciliation chapter: Crohn Disease already had extensive Sabiston-sourced "Surgical treatment" and "Specific problems" content covering nearly every topic Ch48 raises (indications, ileocolic resection, strictureplasty, bypass, anastomotic technique/Kono-S, laparoscopic surgery, colonic/rectal disease, IPAA, duodenal disease). Judgment: reconcile throughout the existing sections rather than add a new standalone section, since Ch48's value is almost entirely in deepening what's already there with trial-level/epidemiologic detail, not in new topics.

• sources/ASCRS Ch48 - Crohn's Disease Surgical Management.md — NEW, full structural summary (changing trends/introduction, indications, bowel obstruction imaging/dilation, perforation, penetrating disease/abscess, cancer and dysplasia, toxic colitis, bleeding, surgical philosophy, nutritional support, MIS/ERP/perioperative steroid-and-biologic management, anastomotic type, disease recurrence surveillance, and operative considerations by location).
• conditions/Crohn Disease.md — frontmatter sources gained Ch48. Extensive edits throughout: (1) declining surgery-rate-by-era data added to the "Surgical treatment (colonic-focused)" intro; (2) anastomotic-technique paragraph extended with a pointer to Anastomotic Construction's new trial-level Kono-S evidence, plus a new mesenteric-excision note; (3) laparoscopic-surgery paragraph gained a new MIS/robotic/SILS detail blockquote, and the existing ERAS blockquote gained an ERP evidence-quality caveat; (4) "Cancer risk" bullet gained a full epidemiology blockquote (age at diagnosis, cumulative risk by duration, stricture-associated-cancer cohort data); (5) "Postoperative complications and recurrence" gained two new blockquotes — perioperative steroid/ biologic management (incl. Table 48.2) and postoperative recurrence-prevention trial evidence (Regueiro, PREVENT, De Cruz); (6) a new nutritional-support/TPN blockquote added before the small-bowel-focused surgical section; (7) "Stricturing disease" bullet gained CT/MR enterography fibrosis-vs-inflammation imaging and balloon-dilation outcome detail; (8) "Strictureplasty" bullet gained full technique-variant (Michelassi, Jaboulay) and outcome detail; (9) "Penetrating disease" bullet gained Hirten's fistula-location-frequency data and detailed abscess/PCD/psoas-abscess management; (10) "Perforation" bullet gained colonic-stricture-specific detail; (11) "Gastrointestinal bleeding" bullet gained expanded localization detail; (12) "Colorectal disease" bullet gained Table 48.3 recurrence/stoma rates by procedure, IPAA-in-Crohn's outcome data, and ileosigmoid fistula management detail; (13) "Duodenal disease" bullet expanded into a full gastroduodenal picture, and a new "Upper small bowel disease" bullet added; (14) "Prognosis" section gained an era-context note reconciling its 71%-at-10-years figure with Ch48's two cohorts; (15) "Open items / gaps" gained a new summary bullet. No new discrepancies identified — Ch48's content was consistent with everything already on the page.
• procedures/Anastomotic Construction.md — frontmatter sources gained Ch48. Kono-S section substantially extended with the full trial-level evidence base (Muñoz-Juárez, the 2007 and later meta-analyses, the CAST trial, the 2013 German RCT, Kono's own multicenter follow-up, Shimada, the first Kono-S RCT) plus the Irish mesenteric-excision report. Added a "Related pages" note and two new "Open items/gaps" bullets flagging this evidence as textbook/secondary-level only.
• Research Priorities.md — two new entries added under the IBD section: the Kono-S RCT (not yet independently ingested despite being this wiki's most load-bearing Kono-S evidence) and the Regueiro/PREVENT postoperative-infliximab-prophylaxis trial pair (flagged as having a genuine gap between their primary conclusions, worth independently verifying).
• sources/Sources.md, index.md — updated with the new Ch48 source entry.

Next up: Chapter 49 (unread as of this entry) continues the sequential front-to-back ASCRS Textbook ingest.

[2026-08-25] Chapter 49 — Ulcerative Colitis: Surgical Management

Read in full (book pages 835-850, PDF pages 828-843) before writing. A detailed UC surgical decision-making/operative-technique chapter (Zaghiyan KN, Fleshner PR). Ulcerative Colitis's existing "Indications for surgery"/"Surgical options" sections were brief and cross-referenced the dedicated Ileal Pouch-Anal Anastomosis (IPAA) page for technique — Ch49 supplies real new depth on both: UC-specific decision-making/epidemiology on the condition page, and full operative technique plus a genuine staging controversy on the procedure page.

• sources/ASCRS Ch49 - Ulcerative Colitis Surgical Management.md — NEW, full structural summary (indications for surgery incl. ASUC risk-scoring and SCENIC dysplasia detail, preoperative planning, IPAA operative technique and staging/pouch-design/anastomosis-type controversies, transanal pouch, ileorectal anastomosis, continent ileostomy).
• conditions/Ulcerative Colitis.md — frontmatter sources gained Ch49. Edits: (1) new blockquote on the elective/emergent surgery split and ASUC colectomy risk-scoring at the top of "Indications for surgery"; (2) "Dysplasia or cancer" bullet gained a full CRC-epidemiology/SCENIC visible-vs- invisible-dysplasia blockquote, cross-compared against Crohn Disease's Ch48-added CD cancer- risk figures; (3) new preoperative-planning blockquote; (4) "Subtotal colectomy with ileorectal anastomosis" bullet expanded into a fully fleshed-out IRA option with failure-rate and cancer-risk- by-procedure data — one internal inconsistency in the chapter's own text (colectomy-for-severe- acute-colitis named as both a failure predictor and, elsewhere, associated with decreased failure risk) flagged rather than silently resolved; (5) IPAA bullet extended with a pointer to the now- much-larger Ileal Pouch-Anal Anastomosis (IPAA) page; (6) "Continent ileostomy" bullet substantially expanded with full Kock-pouch operative/complication detail; (7) "Open items / gaps" gained a new summary bullet.
• procedures/Ileal Pouch-Anal Anastomosis (IPAA).md — frontmatter sources gained Ch49. Major expansion: new "Laparoscopic operative technique, step by step" section; new "Staging controversy: one, two, or three stages" section (incl. the PUCCINI preoperative-biologic-safety trial and obesity/steroid/albumin risk factors); new "Pouch design and anastomosis type" section (J/S/W outcome comparisons, hand-sewn-vs-stapled trial evidence); new "Transanal pouch (ta-J-pouch)" section. "Open items / gaps" gained a new summary bullet.
• Research Priorities.md — two new entries added under the IBD section: the PUCCINI study (the key prospective preoperative-anti-TNF-safety data point, known only secondhand) and the 343-patient French IRA-failure study (worth independently ingesting to resolve the flagged internal inconsistency).
• sources/Sources.md, index.md — updated with the new Ch49 source entry.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 181 total files (180 → 181: one new source page). Wikilink resolution re-checked (pipe-aware, alias-aware, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: not yet pushed — continuing the ingest locally; queued for the next successful device-bridge connection.

Next up: Chapter 50 ("Complications of the Pelvic Pouch," Ashburn JH, Dietz DW) continues the sequential front-to-back ASCRS Textbook ingest — a natural companion to this chapter and a likely significant reconciliation/extension target for Ileal Pouch-Anal Anastomosis (IPAA)'s existing "Complications" section (afferent limb syndrome and Crohn's-disease-of-the-pouch vs. mimics were visible during this chapter's PDF read but not yet ingested).

[2026-08-25] Chapter 50 — Complications of the Pelvic Pouch

Read in full (book pages 851-864, PDF pages 844-857) before writing (Ashburn JH, Dietz DW). Unlike Ch48/Ch49, this was not primarily a reconciliation chapter: Ileal Pouch-Anal Anastomosis (IPAA)'s existing "Complications" section was very brief on structural/inflammatory/functional/neoplastic pouch complications, so Ch50 supplies an entirely new complications framework rather than deepening an already-detailed one. One genuine correction (not just an extension) was identified and flagged explicitly in the wiki text: Ch50's finding that up to three-quarters of "CD of the pouch" diagnoses were reclassified as afferent-limb syndrome after specialty re-evaluation nuances/corrects — rather than merely adds to — the page's prior "late Crohn's diagnosis" framing. Ch50's pouchitis clinical-categories/treatment-algorithm content was judged complementary to (not competing with) the existing Ch43-sourced genetic/microbiome pathobiology already on the page, so both were kept side by side rather than reconciled into one narrative.

• sources/ASCRS Ch50 - Complications of the Pelvic Pouch.md — NEW, full structural summary (introduction/approach to the dysfunctional pouch, structural complications incl. afferent limb syndrome and issues of the pouch body/efferent limb, inflammatory complications incl. pouchitis/ cuffitis/Crohn's disease of the pouch, functional complications incl. irritable pouch syndrome and dyssynergic defecation, neoplasia of the pouch, and outcomes of surgical management incl. the Mayo/ St Mark's/Remzi excision-and-redo series).
• procedures/Ileal Pouch-Anal Anastomosis (IPAA).md — frontmatter sources gained Ch50. Major expansion: (1) the existing "Complications" section's "Late" bullet gained an explicit correction/ nuance paragraph re: AL syndrome vs. CD of the pouch misdiagnosis; (2) new "Approach to the dysfunctional pouch" section; (3) new "Structural complications" section (afferent limb syndrome; issues of the pouch body — PAA defect/leak, anastomotic sinus, "tip of J" leak, floppy-pouch scaffolding failure, mesenteric rotation, residual mesorectum; efferent limb problems); (4) the existing "Pouchitis" section gained a clinical-categories/treatment-algorithm paragraph explicitly framed as complementary to the existing pathobiology content; (5) new "Cuffitis" section; (6) new "Crohn's disease of the pouch" section; (7) new "Functional complications: irritable pouch syndrome and dyssynergic defecation" section; (8) new "Neoplasia of the pouch" section; (9) new "Managing pouch failure: excision vs. revision" section, cross-linked to Ulcerative Colitis's continent- ileostomy content as a pouch-salvage option; (10) "Open items / gaps" — the old "cuffitis mentioned only in passing" bullet struck through and marked resolved; new summary bullet added noting the entirely-new complications framework and listing all named studies (Mayo/St Mark's/Remzi series,

  3000-patient neoplasia cohort) as textbook/secondary-level only.

• conditions/Ulcerative Colitis.md — no frontmatter sources change (Ch50's content lives on the procedure page). One addition: the "Continent ileostomy" bullet gained a cross-reference to its use as a pouch-salvage option for failed IPAA, per Ch50.
• sources/Sources.md, index.md — updated with the new Ch50 source entry.
• Research Priorities.md — two new entries added under the IBD section: the Remzi redo-pouch series (>500 patients) and the >3000-patient pouch-neoplasia cohort, both known to the wiki only via Ch50's secondary summary.

Next up: Chapter 51 ("Infectious Colitis," Reickert CA & Abbas MA) continues the sequential front-to-back ASCRS Textbook ingest (confirmed to begin at book page 865 / PDF page 858).

[2026-08-25] Chapter 51 — Infectious Colitis

Read in full (book pages 865-877, PDF pages 858-870) before writing (Reickert CA, Abbas MA). A broad survey chapter — bacterial, parasitic, fungal, and viral colitidities, plus a dedicated immunocompromised-host section (IBD, HIV, transplant). C. difficile itself is explicitly deferred to the next chapter and not covered in depth here. Unlike the reconciliation-heavy Ch48/Ch49, this was a substantial-expansion chapter like Ch50: Infectious Colitis's existing content (from Sabiston Ch52 - Infectious & Ischemic Colitis) covered CDI in depth but only a compact 4-pathogen bacterial table and a brief CMV paragraph — Ch51 supplies much fuller bacterial detail plus two entirely new organism classes (parasitic, fungal) that didn't exist on the page at all, and a genuinely new immunocompromised-host clinical-reasoning layer. One page-boundary note: the offset between PDF and book pagination shifts from +7 to +8 starting with Chapter 52 (book 879 = PDF 871, confirmed by printed folio) — a blank unnumbered page apparently falls between Ch51 and Ch52.

• sources/ASCRS Ch51 - Infectious Colitis.md — NEW, full structural summary (bacterial colitidities incl. Campylobacter/Salmonella/Shigella/E. coli pathotypes/Yersinia/Vibrio/other; parasitic colitidities incl. amebic colitis in depth and eleven other parasites; fungal colitidities incl. Histoplasma/Candida/Aspergillus/Cryptococcus; viral colitidities incl. a deepened CMV writeup and other viruses; infectious colitis in immunocompromised patients incl. IBD/HIV/transplant).
• conditions/Infectious Colitis.md — frontmatter sources gained Ch51. Major expansion: (1) intro updated to note both textbook sources and point to the new immunocompromised-host section; (2) "Other enteric pathogens" retitled "Other enteric bacterial pathogens," original table retained, full prose detail added per organism (Campylobacter, Salmonella, Shigella deepened; E. coli/STEC, Vibrio, and "other bacterial" — TB/Aeromonas/Bacteroides/Listeria — added new); (3) new "Parasitic colitidities" section (amebic colitis in full depth incl. the 112-case Mexico City perforation series, plus eleven other parasites more briefly); (4) new "Fungal colitidities" section (Histoplasma/Candida/Aspergillus/Cryptococcus); (5) "Viral colitidities" section — CMV paragraph substantially deepened (epidemiology, "owl's eye" diagnostic detail, colonization-vs-active distinction, treatment, Galiatsatos perforation-mortality data), new "Other viral colitidities" paragraph added; (6) new "Infectious colitis in immunocompromised patients" section (IBD — incl. the clinical warning that infectious colitis in IBD patients is often mistreated as an IBD exacerbation by escalating immunosuppression, with an illustrative amebic-colitis-mistaken-for-UC case; HIV; transplant patients incl. a 422-patient diarrhea-etiology review), explicitly cross-referencing Enteritis in the Immunocompromised Host for the more granular pre-existing AIDS/transplant-specific organism list rather than duplicating it; (7) "Open items / gaps" gained a new summary bullet.
• conditions/Enteritis in the Immunocompromised Host.md — frontmatter sources gained Ch51. Reconciliation edits: Viruses section gained a cross-reference to Infectious Colitis's deeper Ch51-sourced CMV writeup; Fungi section gained a cross-reference noting Ch51 deepens Histoplasma (PDH mechanism) and adds three organisms (Candida, Aspergillus, Cryptococcus) not previously on this page; the existing "Open items / gaps" bullet asking for exactly this cross-linking was struck through and marked Resolved.
• conditions/Inflammatory Bowel Disease.md — frontmatter sources gained Ch51. The existing "CMV and C. difficile superinfection" perioperative-management bullet gained a new paragraph citing Ch51's sharper clinical warning (infectious colitis in IBD often mistreated as an IBD exacerbation, with sepsis/perforation risk) and its illustrative amebic-colitis case, pointing to Infectious Colitis's new section for the fuller picture.
• sources/Sources.md, index.md — updated with the new Ch51 source entry.
• Research Priorities.md — no new entries. This chapter is breadth-over-depth (109 references spanning epidemiology/case-reports/a few retrospective series) with no single named trial or study load-bearing enough to warrant independent-ingestion flagging, unlike prior chapters.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 183 total files (182 → 183: one new source page). Wikilink resolution re-checked (pipe-aware, alias-aware — including frontmatter aliases:, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally; queued for the next successful device-bridge connection.~~ Pushed — 7 files (1 new + 6 edited: sources/ASCRS Ch51 - Infectious Colitis.md, conditions/Infectious Colitis.md, conditions/Enteritis in the Immunocompromised Host.md, conditions/Inflammatory Bowel Disease.md, sources/Sources.md, index.md, log.md), "rejected":[], confirmed via device_commit_files.

Next up: Chapter 52 ("Clostridium difficile Infection," Paquette IM & Stewart DB) continues the sequential front-to-back ASCRS Textbook ingest — confirmed to begin at book page 879 / PDF page 871 (note the +8 offset from this chapter boundary onward, vs. +7 previously). A dedicated CDI chapter that will need careful reconciliation against Infectious Colitis's already-extensive, Sabiston-sourced CDI section.

[2026-08-25] Chapter 52 — Clostridium difficile Infection

Read in full (book pages 879-891, PDF pages 871-883) before writing (Paquette IM, Stewart DB). A dedicated, much more granular CDI chapter than the wiki's existing Sabiston-sourced content — heavy reconciliation chapter, deepening nearly every existing subsection on Infectious Colitis's CDI section rather than requiring new top-level structure (two genuinely new subsections were added: Nomenclature/genetics, and Ribotype/clinical severity). Unlike Ch51, this chapter is unusually trial-rich for a survey chapter — five named studies (Zar 2007, Neal 2011, the EAST 2017 multicenter study, the EXTEND trial, and a Cochrane review) are load-bearing enough to flag for independent ingestion. One more page-boundary note: the offset shifts again, from +8 to +9, starting at Chapter 53 (book 893 = PDF 884, confirmed by printed folio — another blank unnumbered page between chapters).

• sources/ASCRS Ch52 - Clostridium difficile Infection.md — NEW, full structural summary (epidemiology incl. economic burden; clinical risk factors incl. advanced age, antibiotic treatment, healthcare-facility contact, immunocompromised states, IBD, perioperative prophylaxis/bowel prep, PPIs; nomenclature and genetics; ribotype and clinical severity; diagnosis incl. the GDH→EIA→NAAT algorithm; two severity schemas; antibiotic therapy trial evidence; surgery for CDI trial evidence; FMT).
• conditions/Infectious Colitis.md — frontmatter sources gained Ch52. Major reconciliation of the existing CDI section: (1) Epidemiology deepened with economic-burden data and the most-common-hospital-acquired-infection claim; (2) "Microbiology and transmission" retitled "Microbiology, nomenclature, and genetics," gained the Clostridioides nomenclature/PaLoc/toxin mechanism detail plus a new "Ribotype and clinical severity" subsection; (3) "Risk factors" gained quantified ORs for antibiotics/PPIs, the TNFRSF14 IBD genetic risk factor, the perioperative

  24h-antibiotic 6.7-fold CDI risk finding, and the New York hospital-level-variation study; (4) "Clinical presentation and severity" gained the ACG severity schema (as a comparison table alongside the existing IDSA one) and the carrier-state distinction; (5) "Diagnosis" gained the testing-method evolution and current GDH/EIA/NAAT algorithm; (6) "Treatment" gained the Zar 2007, fidaxomicin Phase III, EXTEND, and Cochrane-review trial evidence behind the existing dosing table, plus FMT and surgery subsections substantially expanded with Neal 2011/EAST 2017/2019-NIS trial-level surgical evidence; (7) "Open items / gaps" updated to name the five specific studies now flagged in Research Priorities.md rather than describing the gap generically.

• conditions/Inflammatory Bowel Disease.md — frontmatter sources gained Ch52. The existing "CMV and C. difficile superinfection" bullet gained the TNFRSF14/colectomy-risk data and Ch52's own "CDI in IBD patients should be treated with vancomycin" key-concept, cross-checked against and found consistent with Infectious Colitis's existing vancomycin-first treatment table.
• conditions/Enteritis in the Immunocompromised Host.md — frontmatter sources gained Ch52. The existing brief C. difficile bullet gained a cross-reference to Infectious Colitis's now much deeper CDI writeup plus the HIV-specific CD4-count CDI-risk figure (OR 5.2–27.6 at CD4 ≤50/mm³).
• sources/Sources.md, index.md — updated with the new Ch52 source entry.
• Research Priorities.md — five new entries added under the "Infectious colitis" section: Zar 2007 RCT, Neal 2011, the EAST 2017 multicenter study, the EXTEND trial, and the CDI-antibiotics Cochrane review — all known to the wiki only via this chapter's secondary summary.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 184 total files (183 → 184: one new source page). Wikilink resolution re-checked (pipe-aware, alias-aware incl. frontmatter aliases:, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally; queued for the next successful device-bridge connection.~~ Pushed — 8 files (1 new + 7 edited: sources/ASCRS Ch52 - Clostridium difficile Infection.md, conditions/Infectious Colitis.md, conditions/Inflammatory Bowel Disease.md, conditions/Enteritis in the Immunocompromised Host.md, Research Priorities.md, sources/Sources.md, index.md, log.md), "rejected":[], confirmed via device_commit_files.

Next up: Chapter 53 ("Radiation, Microscopic, and Ischemic Colitis," Cannon JA & Kennedy GD) continues the sequential front-to-back ASCRS Textbook ingest — confirmed to begin at book page 893 / PDF page 884 (offset +9, one higher than Ch52's +8). Already skimmed during this session's PDF read (radiation colitis grading/management incl. formalin/ABC endoscopic therapy; microscopic colitis incl. budesonide trial evidence; ischemic colitis incl. the mesenteric-ischemia-vs-IC distinction) — a full dedicated read-through is still needed before writing it up, and it looks like a three-condition chapter that may map onto three separate existing wiki pages (or need at least one new one, since microscopic colitis doesn't appear to have an existing dedicated page yet).

[2026-08-25] Chapter 53 — Radiation, Microscopic, and Ischemic Colitis

Read in full (book pages 893-905, PDF pages 884-896) before writing (Cannon JA, Kennedy GD). A three-condition survey chapter, unusually trial-rich throughout (unlike Ch51's breadth-over-depth style) — most claims across all three sections cite specific named studies with quantified results. Two entirely new condition pages created; the existing Ischemic Colitis page received a substantial reconciliation. One page-boundary note: Chapter 54 ("Intestinal Stomas") begins immediately at PDF page 897 — corrected in the Chapter 55 entry below: the offset actually shifts to +10 there, not "no further shift" as originally logged here.

• sources/ASCRS Ch53 - Radiation, Microscopic, and Ischemic Colitis.md — NEW, full structural summary of all three conditions (radiation colitis epidemiology/prevention/formalin-ABC-endoscopic therapy/surgery; microscopic colitis epidemiology/risk factors/diagnostic criteria/budesonide treatment ladder; ischemic colitis epidemiology-by-subgroup/diagnosis/ghost cells/management).
• conditions/Radiation Colitis (Proctitis).md — NEW condition page, deliberately kept separate from the existing, Sabiston-sourced Radiation Enteritis (small bowel) given a distinct colorectal-specific presentation (hemorrhagic proctitis) and treatment armamentarium (topical formalin as first-line, argon beam coagulation as a near-equivalent alternative, surgery as a last resort). Cross-linked both directions with Radiation Enteritis.
• conditions/Microscopic Colitis.md — NEW condition page (no prior page existed for this condition): collagenous vs. lymphocytic subtypes, epidemiology, autoimmune/smoking/medication risk factors, Spanish Microscopic Colitis Group diagnostic criteria, budesonide-anchored treatment ladder incl. two named induction/maintenance RCTs (Miehlke, Münch), surgical options (diversion ± resection) as a last resort.
• conditions/Ischemic Colitis.md — frontmatter sources gained Ch53. Substantial reconciliation: (1) added a formal mesenteric-ischemia-vs-ischemic-colitis comparison table (Table 53.2); (2) new "Epidemiology by patient subgroup" section (COPD rates up to 100/100,000; AAA-repair-specific incidence 0–4.6% elective vs. up to 21% emergency); (3) Presentation gained LGIB-etiology proportion data (Newman, Hreinsson) with a cross-reference to Lower Gastrointestinal Hemorrhage; (4) Imaging gained the Iacobellis CT-accuracy study (100% CT-positive in the acute phase, >70% mortality when pneumatosis and necrosis coexist); (5) Endoscopy gained findings-by-frequency data and the pathognomonic "ghost cells" histologic finding; (6) Treatment gained a corroborating surgical-mortality figure (Scharff, up to 40%) alongside the existing 25%/47% range; (7) "Open items / gaps" gained two new flagged studies.
• conditions/Radiation Enteritis.md — added a cross-reference at the top pointing to the new Radiation Colitis (Proctitis) page for the colon/rectum-specific presentation, clarifying this page's scope is small-bowel-specific.
• conditions/Conditions.md — landing page updated: Ischemic Colitis entry expanded, Radiation Enteritis entry clarified as small-bowel-specific, two new entries added (Radiation Colitis (Proctitis), Microscopic Colitis).
• sources/Sources.md, index.md — updated with the new Ch53 source entry and the two new condition pages.
• Research Priorities.md — six new entries added under a new "Microscopic and ischemic colitis" section: the Miehlke and Münch budesonide RCTs, the Spanish Microscopic Colitis Group (Fernandez-Banares) consensus statement, the Higgins epidemiology review, the Iacobellis CT-accuracy study, and the Scharff surgical-outcome study — all known to the wiki only via this chapter's secondary summary.

Next up: Chapter 54 ("Intestinal Stomas," McGee MF & Cataldo PA) continues the sequential front-to-back ASCRS Textbook ingest — begins immediately at PDF page 897 (offset corrected in the Chapter 55 entry below to +10, not +9 as originally logged here). Already skimmed during this session's PDF read (stoma types/siting, ileostomy effluent composition, complications) — a full dedicated read-through is still needed before writing it up.

[2026-08-25] Chapter 54 — Intestinal Stomas

Read in full (book pages 907-946, PDF pages 897-936) before writing (McGee MF, Cataldo PA). By far the longest chapter ingested to date (40 PDF pages, 38 figures) but comprehensive rather than padded. No prior wiki page existed for stomas at all — created as an entirely new procedure page rather than reconciling existing content. Filed under procedures/ (not conditions/) per the established IPAA precedent, since stomas are primarily a surgical construct even though the chapter covers extensive complication/management detail. One page-boundary note: Chapter 55 ("Abdominal Wall Reconstruction and Parastomal Hernia Repair") begins immediately at PDF page 937 with no offset shift from Ch54's +10 (see the offset correction noted in the Chapter 55 entry below — this chapter's own offset was originally mislogged as +9, unchanged from Ch53, when it is actually +10).

• sources/ASCRS Ch54 - Intestinal Stomas.md — NEW, full structural summary (configuration/ indications and physiology for colostomy/ileostomy/jejunostomy; preoperative siting/education; technical creation incl.

• procedures/Intestinal Stomas.md — NEW procedure page (no prior page existed): configuration/ indications (end vs. loop colostomy, ileostomy, jejunostomy) and physiology by stoma type; preoperative considerations (stoma triangle siting, preoperative education outcome data); technical creation for small bowel end/loop stomas and end/loop colostomies (ICG near-infrared perfusion assessment, Brooke sutures, stoma rod evidence); postoperative care and appliance selection; complications (ischemia/necrosis/retraction/stenosis incl. the bedside "test tube" exam, peristomal skin disorders and fungal infection, peristomal pyoderma gangrenosum, peristomal varices incl. TIPS/PSC-specific detail, stoma prolapse, peristomal abscess, high output stomas with a full dietary/pharmacologic management ladder); stoma reversal (preoperative preparation, contentious timing evidence for loop and end stomas, stapled-vs-handsewn technique, reversal complication rates, loop-ileostomy-vs-colostomy comparison); special considerations (the difficult/obese-patient stoma incl. loop-end configuration and "pie crusting," genitourinary stomas, the Turnbull blowhole colostomy, ileostomy/foodstuff bolus obstruction). Cross-referenced into Diverticulitis, Crohn Disease, Ulcerative Colitis, Ileal Pouch-Anal Anastomosis (IPAA), Radiation Colitis (Proctitis), Infectious Colitis, and Short Bowel Syndrome.
• procedures/Procedures.md, index.md — landing pages updated with the new procedure page.
• sources/Sources.md, index.md — updated with the new Ch54 source entry.
• Research Priorities.md — no new entries. Unlike Ch52/Ch53, this chapter is not particularly trial-rich for its most consequential claims (siting technique, perfusion assessment, and complication-management algorithms are expert-consensus/technique detail rather than RCT-driven). A Scandinavian early-vs-late loop ileostomy closure RCT, the HASTA stapled-vs-handsewn trial, and a stoma-rod meta-analysis (finding increased complications with rod use) are noted in the source page as worth independent verification if stoma-specific research questions arise, but judged lower priority than the wiki's existing backlog.

Next up: Chapter 55 ("Abdominal Wall Reconstruction and Parastomal Hernia Repair," Petro CC, Prabhu A, Rosen MJ) continues the sequential front-to-back ASCRS Textbook ingest — begins immediately at PDF page 937 (offset corrected in the Chapter 55 entry below to +10, not +9 as originally logged here).

[2026-08-26] Chapter 55 — Abdominal Wall Reconstruction and Parastomal Hernia Repair

Read in full (book pages 947-959, PDF pages 937-949) before writing (Petro CC, Prabhu A, Rosen MJ). Despite the chapter's title, its content is almost entirely about parastomal hernia repair specifically — the "abdominal wall reconstruction" techniques it describes (retromuscular repair, transversus abdominis release/TAR) appear only in the parastomal-defect-repair context, not as standalone general AWR content. This is the chapter Intestinal Stomas (Ch54) explicitly deferred its parastomal hernia detail to. One page-boundary note: Chapter 56 ("Functional Disorders After Colorectal Surgery/IBS") begins at PDF page 951, immediately after a "Part V: Pelvic Floor Disorders" section-divider page at PDF page 950 — this marks a new textbook Part, not necessarily a new offset regime; offset will be reconfirmed against printed folio when Ch56 is read.

Offset correction (discovered while preparing to read Chapter 56): cross-checking the "© Springer Nature Switzerland AG 2022 <page>" copyright line printed on each chapter's own first page against this chapter's PDF page confirms book page 947 = PDF page 937, offset +10 — not +9 as this log previously claimed. The same cross-check on Chapter 54's first page (book page 907 = PDF page 897) shows its true offset is also +10, not the "+9, unchanged from Ch53" this log stated in the Chapter 53 and Chapter 54 entries above. In other words, the offset actually stepped from +9 to +10 at the Ch53/Ch54 boundary, one chapter earlier than previously tracked — Ch53 alone is +9; Ch54 and Ch55 are both +10. This was caught by grepping the copyright line across all three chapters' extracted text (ch53_full.txt/ch54_full.txt/ch55_full.txt) rather than by any downstream symptom — no book-page citations already written for Ch54 or Ch55 content appear to have been affected, since both chapters' own "Read in full (book pages ..., PDF pages ...)" headers above already reflect the correct +10 arithmetic (907–897 and 947–937 both equal 10); only the prose description of the offset ("unchanged," "no shift") was wrong, not any page number actually cited. The three inline notes above (in the Chapter 53 and Chapter 54 entries) have been corrected to point here rather than rewritten silently. Chapter 56's own offset has not yet been independently confirmed — pending the copyright-line check when Ch56's text is pulled next.

• sources/ASCRS Ch55 - Abdominal Wall Reconstruction and Parastomal Hernia Repair.md — NEW, full structural summary (incidence by stoma type, risk factors/diagnosis, classification systems, operative indications, preoperative optimization, all repair techniques with outcome tables, decision algorithm, mesh selection).
• procedures/Parastomal Hernia Repair.md — NEW procedure page (no prior page existed — previously only a bare incidence figure lived on Intestinal Stomas's complications table): incidence by stoma type (end colostomy highest, loop ileostomy lowest), risk factors (BMI/waist circumference as the strongest evidence-supported association, per a 6,300-patient Swedish registry), diagnosis (self-reported symptoms correlating with need for repair better than CT imaging), symptom/ complication rate table, four historical classification schemes plus the EHS 2014 system, evidence for a selective operative approach (up to 70% of PSH patients never pursue repair; recurrence >50% even with mesh), preoperative optimization targets (BMI, smoking cessation, HbA1c, stoma marking, no routine bowel prep), and the full repair-technique armamentarium with outcome tables: primary repair (~80% recurrence, abandoned), onlay mesh (pooled 19% recurrence), open intraperitoneal mesh (keyhole vs. Sugarbaker), laparoscopic intraperitoneal mesh (DeAsis meta-analysis: Sugarbaker 10% vs. keyhole 28% recurrence — the direct evidentiary basis for "laparoscopic Sugarbaker is the procedure of choice"), and open retromuscular repair/TAR (incl. the chapter authors' own less-favorable experience with the Pauli TAR/Sugarbaker variant, preserved as a methodological caution rather than smoothed over); the chapter's own decision algorithm; and mesh selection (synthetic vs. biologic/biosynthetic trade-offs, incl. the Warren et al. 2020 402-patient contaminated-field synthetic mesh series).
• procedures/Intestinal Stomas.md — cross-reference updated: the complications-table mention of parastomal hernia now links to Parastomal Hernia Repair instead of describing it as not-yet-ingested; the corresponding "Open items" bullet updated to match.
• procedures/Procedures.md, index.md — landing pages updated with the new procedure page.
• sources/Sources.md, index.md — updated with the new Ch55 source entry. Also fixed a stray leftover "No new condition/procedure pages created." line in Sources.md's Ch54 entry that contradicted its own "One new page" statement — a copy-paste artifact from the prior session, unrelated to this chapter's content but caught while editing the same section.
• Research Priorities.md — no new entries. The chapter itself explicitly acknowledges no RCTs exist comparing PSH repair techniques (a field-wide evidence gap, not a wiki gap); the two most load-bearing individual sources (the DeAsis meta-analysis, the Warren et al. 2020 series) are noted in the new page's "Open items" as independent-ingestion candidates but not yet flagged, matching the judgment call made for Ch54.

Next up: Chapter 56 ("Functional Disorders After Colorectal Surgery/IBS," Kunitake H, Staller K) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 951, immediately after a "Part V: Pelvic Floor Disorders" section-divider page. Already skimmed during this session's PDF read (Rome IV criteria, IBS pharmacotherapy, levator ani syndrome, coccygodynia, pudendal neuralgia) — a full dedicated read-through is still needed before writing it up, and page offset should be reconfirmed against printed folio given the intervening Part-divider page.

[2026-08-26] Chapter 56 — Functional Disorders After Colorectal Surgery/IBS

Read in full (book pages 963-978, PDF pages 951-966) before writing (Kunitake H, Staller K). Opens "Part V: Pelvic Floor Disorders." Confirmed via the copyright-line cross-check that this chapter's offset is +12 — a jump of +2 from Ch55's +10, landing squarely on the exact question flagged as open in the Chapter 55 entry above. The jump appears to land at the Part-divider page itself (PDF page 950, immediately before this chapter) rather than being a routine +1 chapter-to-chapter drift; the divider page's own book-page number was not independently checked. Chapter 57's offset should not be assumed to continue at +12 without its own independent check.

A broad functional-disorders survey with two major halves — IBS, and chronic pelvic pain syndromes relevant to colorectal practice (IBS-associated pelvic pain, functional anorectal pain, coccygodynia, pudendal neuralgia) — written from a combined colorectal surgery/GI motility perspective. Three entirely new condition pages created; one existing page (Fecal Incontinence) had its brief "Anorectal pain" section reconciled/superseded, and one existing page (Diverticulitis) gained a new cross-reference it previously lacked.

• sources/ASCRS Ch56 - Functional Disorders After Colorectal Surgery-IBS.md — NEW, full structural summary of both halves of the chapter.
• conditions/Irritable Bowel Syndrome (IBS).md — NEW condition page (no prior page existed): Rome IV definition/subtyping (IBS-D/C/M by Bristol stool form), diagnostic workup by subtype (incl. bile acid diarrhea and microscopic colitis as IBS-D mimics), the surgery-avoidance message (misdiagnosis-driven cholecystectomy/hysterectomy/appendectomy), the diverticulitis/SUDD overlap, and the full graduated treatment ladder (dietary/FODMAP, pharmacotherapy by subtype incl. secretagogues and 5-HT₃ antagonists, neuromodulation by bowel habit, psychological treatment). Cross-referenced into Diverticulitis, Microscopic Colitis, Constipation, and the two other new Ch56 pages.
• conditions/Functional Anorectal Pain & Coccygodynia.md — NEW condition page, superseding the brief "Anorectal pain" section previously on Fecal Incontinence (which itself had explicitly deferred full detail to this chapter, cited by book-chapter range "Chaps. 55–59, 65"). Covers the chronic-pelvic-pain framing (IBS/pelvic-pain overlap epidemiology, pelvic floor dyssynergia), the three Rome IV functional anorectal pain subtypes (levator ani syndrome, unspecified functional anorectal pain, proctalgia fugax) each with a full treatment ladder (digital massage, biofeedback — a 157-patient RCT found it superior to EGS/digital massage — local steroid injection, Botox, sphincterotomy for familial proctalgia fugax), and coccygodynia (trauma/idiopathic subtypes, workup, nonoperative treatment, ganglion impar blockade, coccygectomy outcomes).
• conditions/Pudendal Neuralgia.md — NEW condition page, split out from the anorectal-pain page given the depth of its own diagnostic/treatment literature. Entrapment anatomy (four possible levels along the nerve's course to Alcock's canal), the Nantes diagnostic criteria, and an unusually procedural treatment ladder for a "functional disorders" chapter: nerve block, neuromodulation (pudendal and conus medullaris stimulation), nerve ablation, fat grafting, and several named operative decompression techniques (Istanbul technique, operative pudendoscopy, Hibner repeat decompression) with outcome data.
• conditions/Fecal Incontinence.md — "Anorectal pain" section rewritten to a brief summary plus cross-reference to the two new pages; the "Open items" deferral note updated to reflect that Ch56 has now supplied the anorectal-pain slice of the previously-deferred content, while incontinence-specific management (sphincteroplasty, SNS protocols, biofeedback for dyssynergic defecation) remains deferred to still-later chapters. sources and updated bumped.
• conditions/Diverticulitis.md — new "Symptomatic uncomplicated diverticular disease (SUDD) / IBS overlap" note added to the Uncomplicated diverticulitis section (persistent post-resection IBS-like symptoms in up to 25% of patients despite resolved inflammation on pathology; worse outcomes when IBS-like complaints predate elective resection) — this cross-reference did not exist before this chapter. sources, updated, and Related pages updated accordingly.
• conditions/Conditions.md, index.md — landing pages updated with the three new condition pages and the Fecal Incontinence/Diverticulitis reconciliation notes.
• sources/Sources.md — updated with the new Ch56 source entry.
• Research Priorities.md — five new entries added under a new "IBS and functional pelvic pain" section: the Ford et al. 2018 ACG monograph, the Black et al. 2020 secretagogue network meta-analysis, the Chiarioni et al. 2010 levator-ani-syndrome biofeedback RCT, the Robert et al. 2005 pudendal decompression RCT, and the Kleimeyer et al. 2017 coccygectomy cohort.

Offset correction (discovered while preparing to read this chapter): see the dedicated correction note in the Chapter 55 entry above — cross-checking the copyright line on Ch54's and Ch55's own first pages confirmed both are actually offset +10, not the "+9, unchanged from Ch53" this log previously claimed in the Chapter 53 and Chapter 54 entries. This chapter's own offset (+12) was determined fresh via the same method and is not affected by that earlier error, but completes the corrected offset chain: Ch53 = +9, Ch54 = +10, Ch55 = +10, Ch56 = +12.

Next up: Chapter 57 ("Common Tests for the Pelvic Floor") continues the sequential front-to-back ASCRS Textbook ingest — begins immediately at PDF page 967. Offset should be independently reconfirmed via the copyright-line method rather than assumed to continue at +12, given that this chapter's own +12 arrived via an unexplained +2 jump rather than the usual +1 chapter-to-chapter drift.

[2026-08-26] Chapter 57 — Common Tests for the Pelvic Floor

Read in full (book pages 979-994, PDF pages 967-982) before writing (Thorsen AJ, Roth L). Confirmed via the copyright-line cross-check that the offset is unchanged at +12 from Ch56 (979 = 967 + 12 on this chapter's own first page; the Ch57/Ch58 boundary at PDF page 983/book page 995 is also +12) — this chapter-to-chapter transition shows no jump, confirming the earlier +2 jump seen at Ch56 was specific to the "Part V: Pelvic Floor Disorders" divider page rather than an ongoing drift. Chapter 58's offset can reasonably be assumed +12 going forward, though it will still be spot-checked.

A dedicated, technically deep survey of the pelvic floor testing battery — a pure diagnostic- technique chapter rather than a therapeutic-outcomes one. No new pages created; instead, a substantial rewrite/expansion of the existing Anorectal Physiology Testing concept page, which had previously carried only brief technique descriptions sourced from Sabiston Ch52 - Pelvic Floor Disorders & Constipation and ASCRS Ch03 - Anorectal Physiology.

• sources/ASCRS Ch57 - Common Tests for the Pelvic Floor.md — NEW, full structural summary.
• concepts/Anorectal Physiology Testing.md — substantially rewritten. New content: manometry catheter technology (water-perfused, solid-state, air-charged, HRAM/HDAM — incl. the chapter authors' own stated preference for conventional air-charged systems in their labs despite HRAM/ HDAM's availability, since CPT reimbursement doesn't distinguish them and topography data hasn't changed their clinical decision-making); full manometry technique (positioning, stationary vs. stationary-pull-through vs. continuous-pull-through, resting/squeeze pressure, cough reflex); the four-type dyssynergic defecation classification (push adequacy × sphincter response) with its major caveat that up to 90% of asymptomatic controls/non-constipated proctalgia patients can show a "dyssynergic" pattern on this testing; the 2014-2018 London Protocol/classification (a four-part IAPWG consensus distinguishing major/diagnostic from minor/inconclusive anorectal physiology findings); expanded rectal sensation content (hyposensitivity/hypersensitivity disease associations, incl. a new cross-reference to Irritable Bowel Syndrome (IBS)'s IBS-D hypersensitivity); balloon expulsion test's quantified ~50% sensitivity; expanded neurophysiologic testing (surface vs. needle EMG, PNTML's substantial methodologic limitations, spinal motor latency/MEPs shown better tolerated and more often abnormal than PNTML in fecal incontinence); and a fully expanded imaging section — quantified endoanal ultrasound sphincter anatomy (internal sphincter thickness by age, external sphincter anterior-vs-posterior thickness, perineal body length cutoffs), Oxford intussusception grading (worsening fecal incontinence but not constipation with increasing grade), MR defecography, dynamic transperineal/transvaginal/endoanal ultrasound, and echodefecography — an entirely new imaging modality not previously in the wiki.
• concepts/Concepts.md, index.md — landing page entries expanded to reflect the new depth.
• sources/Sources.md — updated with the new Ch57 source entry.
• Research Priorities.md — no new entries. This is a technique/consensus chapter rather than a comparative-outcomes one; no individual cited study is independently load-bearing enough to flag.

Next up: Chapter 58 ("Evaluation of Constipation and Treatment of Abdominal Component," Garrett KA, Ogilvie JW Jr) continues the sequential front-to-back ASCRS Textbook ingest — begins immediately at PDF page 983. Offset confirmed +12 (unchanged) via this chapter's own copyright-line check; should still be spot-checked rather than assumed indefinitely.

[2026-08-26] Chapter 58 — Evaluation of Constipation and Treatment of Abdominal Component

Read in full (book pages 995-1006, PDF pages 983-994) before writing (Garrett KA, Ogilvie JW Jr). Confirmed via the copyright-line cross-check that the offset is unchanged at +12 from Ch57 (995 = 983 + 12 on this chapter's own first page; the Ch58/Ch59 boundary at PDF page 995/book page 1007 is also +12).

Covers the full evaluation and abdominal-component surgical treatment of chronic constipation. No new pages created; instead a substantial expansion of the existing Constipation page, which had previously carried only brief technique/medication mentions from Sabiston Ch52 - Pelvic Floor Disorders & Constipation.

• sources/ASCRS Ch58 - Evaluation of Constipation and Treatment of Abdominal Component.md — NEW, full structural summary.
• conditions/Constipation.md — substantially expanded. New content: full Rome IV subtyping table (functional constipation, IBS-C, opioid-induced constipation, functional defecation disorders, with a new cross-reference to Irritable Bowel Syndrome (IBS) for the FC/IBS-C spectrum); a secondary-causes etiology table; transit-testing technique detail (radiopaque markers with their reproducibility limitation, scintigraphy, wireless pH-pressure capsule, colonic manometry); and a much deeper medical management ladder that resolves the page's prior "no primary trial data" open item — named RCTs are now cited for lubiprostone (Johanson 2008), linaclotide (Lembo 2011), plecanatide (Miner 2017, an agent entirely new to the wiki), tenapanor (an agent entirely new to the wiki), and prucalopride (Camilleri 2016 integrated analysis), plus the PAMORA network meta-analysis (Luthra 2018) for opioid-induced constipation, itself newly covered as its own Rome IV subtype. The chapter's real center of gravity — surgical patient selection for slow transit constipation — is now covered in depth: transit-study and pelvic-floor-testing caveats (abnormal results don't reliably predict outcome in isolation), gastric/small bowel dysmotility and psychiatric-factor considerations, the Staller et al. 2018 multidisciplinary algorithm, the 2016 ASCRS CPG's (explicitly low-quality-evidence) recommendation for colectomy with IRA, long-term outcome data from two cohorts (77%/median-11-year and high-satisfaction/median-16-year, both with meaningful small bowel obstruction and incontinence rates disclosed), anastomotic variants (antiperistaltic cecorectal anastomosis, Jinling procedure), the megarectum caveat (colectomy performs worse; Ileal Pouch-Anal Anastomosis (IPAA) as a small-series alternative the ASCRS CPG explicitly cautions against outside last-resort use, cross-referenced), and less-invasive/ less-standard alternatives (transanal irrigation, antegrade continence enemas, sacral neuromodulation, ileostomy — the last cross-referenced to Intestinal Stomas and Parastomal Hernia Repair).
• conditions/Conditions.md, index.md — landing page entries expanded to reflect the new depth.
• sources/Sources.md — updated with the new Ch58 source entry.
• Research Priorities.md — five new entries added under a new "Constipation medical management" section: the Johanson 2008 lubiprostone RCT, the Lembo 2011 linaclotide trials, the Miner 2017 plecanatide RCT, the Camilleri 2016 prucalopride integrated analysis, and the Luthra 2018 PAMORA network meta-analysis.

Next up: Chapter 59 ("Treatment of Difficult/Obstructive Defecation," Zutshi M, Oliveira LCC) continues the sequential front-to-back ASCRS Textbook ingest — begins immediately at PDF page 995. Offset confirmed +12 (unchanged) via this chapter's own copyright-line check.

[2026-08-26] Chapter 59 — Treatment of Difficult/Obstructive Defecation

Read in full (book pages 1007-1017, PDF pages 995-1005) before writing (Zutshi M, Oliveira LCC). Confirmed via the copyright-line cross-check that the offset is unchanged at +12 for this chapter itself (995 = 1007 − 12 on this chapter's own first page).

While checking the offset at the Ch59/Ch60 boundary, I found a genuine discrepancy — and, on first pass, restated it incorrectly in my own response before catching it. The copyright line on Ch60's first page (PDF page 1006, "Rectal Prolapse 60") reads book page 1019, not 1018 as continuous +12 pagination would predict. I initially said "offset confirmed +12, unchanged" without checking the arithmetic on that second reading — the same category of mistake as the Ch53→Ch54 offset error earlier in this project. Caught it before writing anything chapter-59-specific this time (unlike the Ch53 case, no already-published wiki content needed correcting).

Verified the true picture by reading the running headers on several pages either side of the boundary: Ch59's last page (PDF 1005) reads book 1017; Ch60's first page (PDF 1006) reads book 1019 per its copyright line; Ch60's second page (PDF 1007) reads book 1020. That's a consistent +13 offset from PDF 1006 onward (1006+13=1019, 1007+13=1020), with book page 1018 simply missing — no PDF page corresponds to it. The most likely explanation is a blank print page (a common convention to force a new chapter to start on a recto/odd page) that was omitted when the PDF was created, rather than any misreading on my part. Chapter 60 onward uses offset +13, not +12.

Covers obstructed defecation syndrome (ODS) as an umbrella entity: physiology of defecation, dyssynergic defecation (Rome IV-based, ~4.6% incidence in non-IBS patients), structural causes (rectocele, enterocele/sigmoidocele with degree/size grading, internal prolapse/intussusception, overt rectal prolapse — the last two explicitly deferred by the chapter's own text to Chapter 60), scoring systems (CSI, ODS score, CRQOL, PFDI/CRADI), a diagnostic testing table, and an etiology-specific treatment algorithm (Fig. 59.8).

• sources/ASCRS Ch59 - Treatment of Difficult-Obstructive Defecation.md — NEW, full structural summary including the offset-discrepancy writeup above.
• conditions/Obstructed Defecation Syndrome (ODS).md — NEW umbrella condition page: scoring systems, diagnostic testing, all four structural/functional causes with cross-references, and the treatment algorithm. No existing page covered ODS as a unifying concept, nor enterocele/sigmoidocele or internal prolapse/intussusception specifically — this page now carries that content, with detailed treatment cross-referenced out to Constipation (dyssynergia) and Rectal Prolapse Repair (internal prolapse) rather than duplicated.
• conditions/Rectocele.md — substantially expanded. New: transanal-repair and STARR-for-rectocele outcome data, transvaginal recurrence rate (7.1%) and a meta-analysis preference for native-tissue transvaginal repair, transperineal mesh controversy note, and a cross-reference to the new ODS page. Resolves the page's prior "no recurrence-rate figures" open item and partially resolves its "no head-to-head trial data" item.
• conditions/Constipation.md — new "Treatment of dyssynergic defecation" section added between Medical management and Surgical options for slow transit constipation: physical therapy/biofeedback (with the Kegel-exercise pitfall caution and the Rao 2018 home-vs-office non-inferiority finding), electrogalvanic stimulation, botulinum toxin A injection technique (with an explicit distinct-from-levator-ani-syndrome-Botox note cross-referencing Functional Anorectal Pain & Coccygodynia), myomectomy, and fecal diversion. Resolves the page's long-standing "no detail on anismus treatment" open item, flagged since at least the Ch03/ Ch58 ingests.
• procedures/Rectal Prolapse Repair.md — light edits: STARR and ventral rectopexy sections both gained a note that these same procedures are also used for internal rectal prolapse/intussusception (a distinct, non-protruding entity from the overt prolapse this page otherwise covers), with full technique detail for that indication explicitly deferred to Chapter 60. New open item flagging that this page will need reconciliation once Chapter 60 is ingested.
• conditions/Rectal Prolapse (Procidentia).md — light edit: intro cross-reference to the new ODS page for how the already-mentioned internal/intrarectal prolapse distinction fits the broader obstructed-defecation picture. No content changes beyond the cross-reference.
• conditions/Conditions.md, procedures/Procedures.md, index.md, sources/Sources.md — landing page entries added/updated for the new ODS page and the Rectocele/Constipation/Rectal Prolapse Repair expansions, including the +13 offset discovery in index.md's Sources section.
• Research Priorities.md — five new entries added under a new "Obstructed defecation syndrome treatment" section: the Rao 2018 biofeedback RCT, Faried 2010 surgical-vs-nonsurgical anismus RCT, Van Geluwe 2014 STARR meta-analysis, Nugent 2020 Botox-vs-EGS trial (flagged as actually being about levator ani syndrome, not dyssynergic defecation, despite Ch59 citing it for EGS technique detail), and Grimes 2019 posterior-compartment-prolapse systematic review. Also lightly updated the existing "condition pages with zero primary literature" bullet to note Rectocele's partial progress.

Wikilink resolution re-checked (pipe-aware, alias-aware incl. frontmatter aliases:, newline-detecting) — 0 broken links, 0 newline-embedded wikilinks (log.md's illustrative-text false positives excluded, per established convention).

Push status: ~~not yet pushed — continuing the ingest locally; queued for the next successful device-bridge connection.~~ Pushed — 12 files (2 new: sources/ASCRS Ch59 - Treatment of Difficult-Obstructive Defecation.md, conditions/Obstructed Defecation Syndrome (ODS).md; 10 edited: conditions/Rectocele.md, conditions/Constipation.md, procedures/Rectal Prolapse Repair.md, conditions/Rectal Prolapse (Procidentia).md, conditions/Conditions.md, procedures/Procedures.md, index.md, sources/Sources.md, Research Priorities.md, log.md), "rejected":[], confirmed via device_commit_files.

Next up: Chapter 60 ("Rectal Prolapse," Murphy M, Vogler SA) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1006. Offset is +13 (not +12 — see the correction above), confirmed via the copyright-line cross-check on this chapter's own first page. Chapter 60 will need to reconcile against Obstructed Defecation Syndrome (ODS), Rectal Prolapse (Procidentia), and Rectal Prolapse Repair for the internal-prolapse/ventral- rectopexy and overt-prolapse content this chapter (Ch59) explicitly deferred to it.

[2026-08-27] Chapter 60 — Rectal Prolapse

Read in full (book pages 1019-1033, PDF pages 1006-1020) before writing (Murphy M, Vogler SA). Confirmed via the copyright-line cross-check that the offset is unchanged at +13 for this chapter (both at its own first page and its own last page).

While checking the boundary into Chapter 61 ("Fecal Incontinence: Evaluation and Treatment"), found another +1 jump, to +14: Ch61's first page (PDF page 1021) reads book page 1035 on its copyright line, not 1034 as continuous +13 pagination would predict. This time I checked the arithmetic carefully before writing anything down (learning from the Ch59/Ch60 catch), and cross-verified against two independent later pages in Ch61 (PDF 1022 → book 1036, PDF 1023 → book 1037-equivalent via its own header) — both consistent with +14. This is the same pattern as the Ch59/Ch60 boundary: a book page (1034) with no corresponding PDF page, most likely a blank page forcing the new chapter to start on an odd/recto page in print, dropped when the PDF was created. Chapter 61 onward uses offset +14. Given this is now the second consecutive chapter boundary in Part V to show this exact pattern, I'll check every remaining chapter boundary in this Part explicitly rather than assuming continuity — cheap insurance against a repeat of the Ch53/Ch54-style mistake.

This chapter completes the pelvic-floor/obstructed-defecation arc that Chapter 59 opened, covering full-thickness rectal prolapse in depth: pathophysiology theories, the mucosal-prolapse/internal- intussusception/overt-prolapse distinction, the Oxford rectal prolapse grading system (I-IV internal, V overt), patient questionnaires (IMPACT), prolapse-specific anorectal physiology testing caveats, imaging (defecography vs. dMRD), incarcerated prolapse management, a full perineal-vs-abdominal treatment ladder with extensive named-study outcome data, approach-selection guidance, recurrent- prolapse management, and a dedicated SRUS/colitis-cystica-profunda section.

• sources/ASCRS Ch60 - Rectal Prolapse.md — NEW, full structural summary including both offset findings.
• procedures/Rectal Prolapse Repair.md — near-total rewrite. Corrected a conflation in the prior version: "Posterior mesh rectopexy (modified Ripstein operation)" was actually describing the Wells procedure (1959, posterior mobilization, presacral mesh fixation) under a name borrowed from the Ripstein procedure (1952, anterior sling, technically distinct) — now split into two separate entries. Added two abdominal options missing entirely from the prior version: suture rectopexy (Cutait) and suture rectopexy with sigmoid resection (Frykman-Goldberg). Added one perineal option missing entirely: anal encirclement (Thiersch). Massively expanded ventral mesh rectopexy: D'Hoore technique, posterior colpopexy/sacrocolpopexy add-on, mesh-type and suture-type erosion data (Evans et al., Tejedor et al.), discitis, learning-curve data, robotic-vs-laparoscopic meta-analysis, and its "gold standard in Europe" status. Added a new "Choosing an approach, and recurrent rectal prolapse" section (NSQIP/Danish-registry mortality-by-approach data, recurrence- after-recurrence counseling data from Gurland et al., prior-Altemeier vascular hazard). Updated Altemeier/Delorme with wider, more specific recurrence ranges.
• conditions/Rectal Prolapse (Procidentia).md — substantially expanded. New: pathophysiology theories (mid-rectal intussusception, connective tissue disorders), the mucosal-prolapse/internal- intussusception/overt-prolapse distinction, the Oxford grading table, urinary incontinence/vaginal prolapse concurrence stats (Jackson et al.), prolapse-specific anorectal physiology testing findings (low pressures, paradoxical EMG mimicking dyssynergia), the fluoroscopic-defecography-vs-dMRD comparison (Ramage et al. meta-analysis), and the IMPACT patient questionnaire. Substantially resolves the page's "no primary trial data" open item.
• conditions/Solitary Rectal Ulcer Syndrome (SRUS).md — substantially expanded. New: colitis cystica profunda (CCP) as a related/overlapping disorder with distinguishing biopsy findings, updated ulcer/polyp prevalence figures (23%/74%), argon plasma coagulation as a bleeding-control treatment, and — most importantly — a mechanism-based treatment split (weakness-driven SRUS/CCP treated surgically via rectopexy vs. straining/dyssynergia-driven SRUS/CCP treated with pelvic floor physical therapy, surgery not recommended) that refines the page's prior blanket "surgery rarely indicated" framing.
• conditions/Obstructed Defecation Syndrome (ODS).md — updated the internal-prolapse section with the Oxford grading and the SRUS mechanistic link, and updated the overt-prolapse section from "deferred to Ch60" to a direct cross-reference now that the content exists. Resolves the page's open item flagging this exact gap.
• conditions/Conditions.md, procedures/Procedures.md, index.md, sources/Sources.md — landing page entries updated for all of the above, including both offset findings in index.md's Sources section.
• Research Priorities.md — five new entries added under a new "Rectal prolapse repair technique" section: the Hidaka et al. suture-rectopexy-vs-VMR RCT, Evans et al. mesh-erosion series, Fang et al. NSQIP mortality analysis, Gurland et al. recurrent-prolapse VMR outcomes, and Altomare et al. VMR-vs-STARR comparison. Also updated the "condition pages with zero primary literature" list: checked off Rectal Prolapse (Procidentia)/Rectal Prolapse Repair given the volume of now-available secondary outcome data, and separated out SRUS (still genuinely gapped on medical-therapy primary data) from that entry.

Next up: Chapter 61 ("Fecal Incontinence: Evaluation and Treatment," da Silva G, Mellgren A) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1021. Offset is +14 (verified above against two independent pages, not assumed from continuity). Chapter 61 will need substantial reconciliation against the existing Fecal Incontinence page, which currently covers sphincter-defect/idiopathic/neurologic pathophysiology and dyssynergic-defecation/urogynecologic overlap from earlier ASCRS chapters but has not yet absorbed a dedicated fecal-incontinence-focused chapter's full evaluation/treatment ladder (sacral neuromodulation detail per its Key Concepts preview, sphincteroplasty, and other options likely to be covered).

[2026-08-27] Chapter 61 — Fecal Incontinence: Evaluation and Treatment

Read in full (book pages 1035-1046, PDF pages 1021-1032) before writing (da Silva G, Mellgren A). Confirmed via the copyright-line cross-check that the offset is unchanged at +14 for this chapter (verified at its own first page and cross-checked against two further early pages).

Checked the Ch61/Ch62 boundary explicitly (per the "check every boundary in this Part" resolution from the Ch60 entry) and found no further jump — Ch62 ("Low Anterior Resection Syndrome (LARS)") begins at book page 1047, still offset +14. This makes sense retroactively: Ch61 ends on book page 1046, an even page, so no blank page is needed to force Ch62 to start odd, and the offset holds. This is the first "no jump" boundary since Ch58/Ch59, which nicely confirms the theory (jump only when the previous chapter ends on an odd book page) rather than the jump being some other artifact.

This is the dedicated fecal incontinence (FI) chapter that ASCRS Ch03 - Anorectal Physiology had explicitly deferred evaluation/treatment content to back when that chapter was ingested — by far the largest single deferred-content resolution in the wiki's pelvic floor arc. Covers FI epidemiology (1-19% prevalence, a 4,840-article systematic review), a four-category etiology framework, full evaluation (CCF-FIS scoring, manometry correlations, ultrasound, neurophysiology testing's declining role, defecography, colonoscopy), and an extensive treatment ladder from conservative measures through sacral neuromodulation, bulking agents, PTNS, SECCA, investigational stem cell therapy, the TOPAS anal sling, overlapping sphincteroplasty (full technique), ventral mesh rectopexy, dynamic graciloplasty, magnetic sphincter augmentation, the artificial bowel sphincter, and last-resort diversion/MACE.

• sources/ASCRS Ch61 - Fecal Incontinence Evaluation and Treatment.md — NEW, full structural summary including both offset findings.
• conditions/Fecal Incontinence.md — substantially expanded with new Evaluation and Treatment sections (the page's first treatment content — previously pathophysiology-only). Decided against spinning sphincteroplasty, VMR, or any individual device option into separate procedure pages, since the treatment ladder reads better as one page and none of the individual techniques (aside from VMR, which already has a home on Rectal Prolapse Repair) has enough wiki-wide reuse to justify its own page yet. Added a prevalence figure and a compact four-category etiology framework to the intro. Resolves the page's long-standing "diagnostic algorithms and management strategies deferred to later chapters" open item, flagged since the page's creation from Ch03.
• concepts/Anorectal Physiology Testing.md — light edit: added a corroborating sentence to the existing PNTML methodologic-criticism paragraph, citing Ch61's "faded away as a diagnostic modality" language as confirmation from the treatment-outcome side.
• conditions/Conditions.md, index.md, sources/Sources.md — landing page entries updated, including both offset findings (the jump discovery pattern and its first "no jump" counter-example) in index.md's Sources section.
• Research Priorities.md — five new entries added under a new "Fecal incontinence treatment" section: the Wexner et al. SNM FDA-approval trial, Graf et al. NASHA Dx sham RCT, Knowles et al. CONFIDeNT PTNS RCT, Visscher et al. SECCA sham RCT, and Samaranayake et al. VMR systematic review.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 201 total files (200 → 201: one new source page; one condition page substantially expanded, one concept page lightly touched).

Next up: Chapter 62 ("Low Anterior Resection Syndrome (LARS)," Bordeianou L, Messick CA) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1033. Offset confirmed +14 (unchanged from Ch61) via the copyright-line cross-check on this chapter's own first page. Chapter 62 will need substantial reconciliation against the existing Low Anterior Resection Syndrome (LARS) page (currently sourced from Sabiston Ch52 and ASCRS Ch29 - Proctectomy for Rectal Cancer), since a dedicated LARS chapter is likely to add significant depth beyond what a rectal-cancer-surgery chapter's LARS section would cover.

[2026-08-27] Chapter 62 — Low Anterior Resection Syndrome

Read in full (book pages 1047-1054, PDF pages 1033-1040) before writing (Messick CA). Confirmed via the copyright-line cross-check that the offset is unchanged at +14 for this chapter (verified at its own first page).

Checked the Ch62/Ch63 boundary explicitly (per the standing per-boundary-check discipline) and found no jump — Ch63 ("Sexual Function After Colorectal Surgery") begins at book page 1055, still offset +14. Consistent with the theory: Ch62 ends on book page 1054, an even page, so no forced blank page and no offset jump. This is the second consecutive "no jump" boundary (after Ch61/Ch62), continuing to confirm the mechanism is tied to whether the previous chapter ends on an odd or even book page, not some other per-chapter artifact.

This is the dedicated LARS chapter, and it substantially expanded Low Anterior Resection Syndrome (LARS) well beyond its prior Sabiston/Ch29-sourced content: chronicity data (58%/46%/41% major-symptom rates at 3/12/54 months), the 85%-continent-yet-42%-still-LARS finding, LARS-like symptoms in preserved-rectum patients after pelvic chemoradiotherapy (up to 50%), a dedicated risk-factor list, the POLARS preoperative-prediction nomogram, a new Diagnosis/exclusion-of-mimics section, and a substantially rewritten Treatment section (chronic-disease/"Listen, Educate, Treat" framing, medical therapy incl. topical skin care, biofeedback, an entirely new retrograde colonic irrigation subsection, sacral neuromodulation, PTNS, antegrade continence enemas, fecal diversion).

Flagged discrepancy: this chapter's own text describes the LARS Delphi consensus (325 experts including 156 patients with LARS) as "eight symptoms and five consequences," conflicting with the previously-ingested ASCRS Ch29 - Proctectomy for Rectal Cancer's "eight symptoms and eight consequences" from the same underlying consensus. This chapter's own Fig 62.1 table — badly garbled by pdfplumber's multi-column-to-text flattening — appears on inspection to actually enumerate more than five consequence-like phrases, suggesting "five" is a transcription artifact rather than a genuine second consensus count. Per the established convention for cross-chapter numerical discrepancies (most recently applied to a similar case in Ch59), this is flagged explicitly in the wiki's prose rather than silently resolved in either direction.

• sources/ASCRS Ch62 - Low Anterior Resection Syndrome.md — NEW, full structural summary including the offset confirmation and the Ch62/Ch63 "no jump" finding.
• conditions/Low Anterior Resection Syndrome (LARS).md — near-total expansion: new Prediction and preoperative counseling section (POLARS nomogram), new Diagnosis, and excluding LARS-mimicking conditions section, expanded Definition/Cause/Prevention sections, and a substantially rewritten Treatment section adding an entirely new Retrograde colonic irrigation subsection alongside expanded Medical therapy, Biofeedback, Sacral neuromodulation, PTNS, Antegrade continence enemas, and Fecal diversion subsections. Added a cross-reference to Fecal Incontinence in Related pages (RCI/SNM/PTNS technique detail lives there). Explicitly reconciled this chapter's own SNM systematic-review figures (94 screened, 79.8% implanted, 67.0% median LARS-score improvement) against the pre-existing Ch29-sourced SNS figures (74% success, 32/34 improving) — retained both as complementary data points from different cited study sets rather than merged into one number. Updated Open items to reflect the newly-resolved SNM-figure gap, the newly-flagged Delphi consensus discrepancy, and a newly-identified gap (no head-to-head RCI/SNM/PTNS comparison for LARS). Frontmatter: added sacral-neuromodulation and retrograde-colonic-irrigation tags, added Ch62 to sources, updated: 2026-08-27.
• conditions/Conditions.md, index.md, sources/Sources.md — landing page entries updated, including the offset confirmation and "no jump" finding in index.md's Sources section.
• Research Priorities.md — five new entries added under a new "LARS treatment and prediction" section: the Battersby et al. POLARS nomogram study, van der Heijden et al. postoperative screening/treatment protocol study, Andreyev et al. algorithmic-care RCT, Huang & Koh SNM-for-LARS systematic review, and the RCI-vs-PTNS RCT cited for the new retrograde colonic irrigation subsection.

Next up: Chapter 63 ("Sexual Function After Colorectal Surgery") continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1041, book page 1055. Offset confirmed +14 (unchanged from Ch62) via the copyright-line cross-check.

[2026-08-27] Chapter 63 — Sexual Function After Colorectal Surgery in Women

Read in full (book pages 1055-1066, PDF pages 1041-1052) before writing (Keller DS, Ky-Miyasaka JA). Confirmed via the copyright-line cross-check that the offset is unchanged at +14 for this chapter (verified at its own first page: "© Springer Nature Switzerland AG 2022 1055").

Checked the Ch63/Ch64 boundary explicitly and found no jump — Ch64 ("Male Genitourinary Dysfunction as a Consequence of Colorectal Surgery") begins at book page 1067, still offset +14 (verified copyright line: "© Springer Nature Switzerland AG 2022 1067"). Consistent with the theory: Ch63 ends on book page 1066, an even page, so no forced blank page. Third consecutive "no jump" boundary (after Ch61/Ch62 and Ch62/Ch63).

This is the first of a paired set of chapters on sexual/genitourinary dysfunction after colorectal surgery — Ch64 (not yet ingested) covers male patients. No prior wiki page covered female sexual dysfunction after colorectal surgery as its own topic (existing sexual mentions elsewhere were incidental, e.g. quantified male erectile/ejaculatory dysfunction data on Total Mesorectal Excision (TME) & Sphincter-Sparing Resection and General Postoperative Complications), so this chapter's content became a new concept page rather than a reconciliation.

• concepts/Sexual Function After Colorectal Surgery.md — NEW. Scope/prevalence (19-62% postoperative dysfunction; QoLiRECT study; resection-extent/stoma effects; 40-60% dysfunction after IBD pelvic pouch surgery); a three-part radiation/chemotherapy/surgery etiology framework (detailed pelvic autonomic nerve anatomy — superior/inferior hypogastric plexus; the Dutch TME trial's 14-year follow-up finding; Thyø et al.'s OR 1.80 finding); fertility impact (44-82% IPAA fertility reduction, fertility-preservation options); the four-phase female sexual response model (desire, arousal, orgasm, resolution) with phase-specific treatment; the Pelvic Floor Disorders Consortium's 2020 FSFI-9/PISQ-IR measurement recommendations; patient/provider communication-barrier data; cultural-competency considerations; and multidisciplinary treatment team composition. Deliberately structured (headed "currently female-specific... male content deferred") to also receive Ch64's content once ingested, rather than splitting into two separate pages, given the shared underlying nerve anatomy and conceptual framework.
• sources/ASCRS Ch63 - Sexual Function After Colorectal Surgery in Women.md — NEW, full structural summary including the offset confirmation and the Ch63/Ch64 "no jump" finding.
• procedures/Total Mesorectal Excision (TME) & Sphincter-Sparing Resection.md — light edit: added Sexual Function After Colorectal Surgery to Related pages; frontmatter sources add Ch63, updated: 2026-08-27.
• concepts/General Postoperative Complications.md — light edit: added Sexual Function After Colorectal Surgery to Related pages, and resolved the page's own previously-flagged open item ("female sexual/genitourinary dysfunction... covered only briefly and with conflicting infertility-risk data") — the two different infertility-risk figures (threefold increase vs. 44-82%) are explicitly retained as a genuine range across different cited studies rather than merged into one number. Also added a new open item noting male dysfunction content is deferred to Ch64. Frontmatter sources add Ch63, updated: 2026-08-27.
• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries updated, including both offset findings in index.md's Sources section.
• Research Priorities.md — no new entries; this chapter's content is comprehensive secondary-summary material rather than built around a small number of individually load-bearing primary trials.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 204 total files (202 → 204: two new pages, one concept and one source; two pages lightly cross-referenced).

Next up: Chapter 64 ("Male Genitourinary Dysfunction as a Consequence of Colorectal Surgery," Mantilla N, McNevin S) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1053, book page 1067. Offset confirmed +14 (unchanged from Ch63) via the copyright-line cross-check. Chapter 64 will reconcile into the same Sexual Function After Colorectal Surgery page created this entry, adding a male-specific section alongside the existing female-specific content.

[2026-08-27] Chapter 64 — Male Genitourinary Dysfunction as a Consequence of Colorectal Surgery

Read in full (book pages 1067-1075, PDF pages 1053-1061) before writing (Mantilla N, McNevin S). Confirmed via the copyright-line cross-check that the offset is unchanged at +14 for this chapter (verified at its own first page: "© Springer Nature Switzerland AG 2022 1067").

Checked the Ch64/Ch65 boundary explicitly and found a new +1 jump to +15 — Ch65 ("Middle and Anterior Pelvic Compartment: Issues for the Colorectal Surgeon") begins at book page 1077, not 1076 (verified copyright line: "© Springer Nature Switzerland AG 2022 1077"). Consistent with the established theory: Ch64 ends on book page 1075, an odd page, forcing a blank page in print that's dropped from the PDF. This is the fourth chapter-boundary offset jump found across this ingest arc (after Ch59/Ch60 and Ch60/Ch61), and the first jump since the run of "no jump" boundaries at Ch61/Ch62, Ch62/Ch63, and Ch63/Ch64 — a useful reminder that "no jump" runs don't mean the pattern has stopped, only that recent chapters happened to end on even pages.

This chapter completes the paired sexual/genitourinary-dysfunction set begun by Ch63, covering male patients. Added a new "Male genitourinary dysfunction" top-level section to the Sexual Function After Colorectal Surgery page created for Ch63, organized in parallel to its existing "Female sexual dysfunction" section (both now nested under ## headers with the page's prior top-level sections demoted to ###/####).

• concepts/Sexual Function After Colorectal Surgery.md — restructured (female content demoted under a new "Female sexual dysfunction" ## header) and expanded with the new "Male genitourinary dysfunction" ## section: detailed sympathetic/parasympathetic pelvic neuroanatomy (ejaculation vs. erection pathways), male sexual/urinary functional metrics (IIEF-15, SHIM/IIEF-5, EPIC, UDI, King's Health Questionnaire, Danish Prostatic Symptom Score, ICS male questionnaires), a procedure-specific genitourinary-risk gradient (anterior resection lowest, APR highest), a full ED/urinary-dysfunction management ladder (VCD, intracorporeal injections, intraurethral alprostadil, oral PDE5 inhibitors, penile prosthesis, retrograde-ejaculation fertility workaround, catheterization escalation), psychological impact/counseling guidance, an extended LGBTQ section (the clinically-defined anodyspareunia syndrome with its own prevalence figures, and the Gay Sexual Functioning Inventory from the Restore Study — explicitly flagged as validated only in a prostate-cancer population, not yet in colorectal surgery patients), and fecal-diversion-specific sexual/QOL impact data (80% lifestyle change, 40% impaired sexuality, elevated ostomate suicide risk). Related pages and Open items updated to cover both sexes; frontmatter tags add erectile-dysfunction and LGBTQ, sources add Ch64, updated: 2026-08-27.
• sources/ASCRS Ch64 - Male Genitourinary Dysfunction as a Consequence of Colorectal Surgery.md — NEW, full structural summary including the offset confirmation and the newly-discovered Ch64/Ch65 jump.
• procedures/Abdominoperineal Resection (APR).md — light edit: added Sexual Function After Colorectal Surgery to Related pages, and extended its existing "APR-specific sexual/urinary dysfunction rates" open item to note Ch64 corroborates APR as highest-risk (and names the contributing mechanisms) without providing APR-specific quantification either — the gap remains open, now with a second source confirming rather than resolving it. Frontmatter sources add Ch64, updated: 2026-08-27.
• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries updated to describe both the female and male sections of the concept page, including the new offset-jump finding in index.md's Sources section.
• Research Priorities.md — no new entries; this chapter's content is comprehensive secondary-summary material rather than built around a small number of individually load-bearing primary trials.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 205 total files (204 → 205: one new source page; one concept page expanded with a new parallel section, one procedure page lightly cross-referenced).

Next up: Chapter 65 ("Middle and Anterior Pelvic Compartment: Issues for the Colorectal Surgeon," Patterson D, Gearhart SL, Birnbaum E) continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1062, book page 1077. Offset is now +15 (confirmed above against the copyright line — not assumed from continuity, per the newly-confirmed Ch64/Ch65 jump).

[2026-08-27] Chapter 65 — Middle and Anterior Pelvic Compartment: Issues for the Colorectal Surgeon

Read in full (book pages 1077-1086, PDF pages 1062-1071) before writing (Patterson D, Gearhart SL, Birnbaum E — all three authors urogynecology/gynecology, not colorectal surgery). Confirmed via the copyright-line cross-check that the offset is +15 for this chapter (the jump from +14 predicted at the end of the Ch64 entry, now confirmed via "© Springer Nature Switzerland AG 2022 1077").

Checked the Ch65/Ch66 boundary explicitly and found a second, differently-caused jump. Ch65 ends on book page 1086, an even page — by the usual chapter-boundary rule this predicts no further jump. However, PDF page 1072 turned out to be a Part divider page ("Part VI: Miscellaneous") with no chapter content of its own, and Ch66 ("Pediatric Colorectal Disorders") begins at PDF page 1073 with copyright line "© Springer Nature Switzerland AG 2022 1089" — offset +16, one more than predicted. Working through the mechanism: the Part divider itself is printed on its own recto (odd) page — book page 1087 — with a blank verso at book page 1088 dropped from the PDF, the same recto-forcing convention normally seen at chapter boundaries, applied here to a Part transition instead of a chapter transition. This is the fifth offset jump found across the ingest arc (after Ch59/Ch60, Ch60/Ch61, and Ch64/Ch65), and the first attributable to a Part divider rather than a plain chapter boundary — worth watching for at any future Part transitions in the remaining textbook.

This chapter resolves a gap explicitly flagged and deferred on three existing pages, each of which had noted (in slightly different words) that fuller enterocele/sigmoidocele and multidisciplinary-POP detail was waiting on "a future urogynecology-focused source" being ingested. That source has now arrived.

• concepts/Pelvic Organ Prolapse (Anterior & Middle Compartment).md — NEW. Scoped deliberately narrow, on the same design logic as Colorectal Endometriosis: POP definition/etiology/ epidemiology (three-compartment model, prevalence, vaginal-parity risk data, recurrence-risk factors), evaluation (symptom domains, PFDI-20/PFIQ-7/PISQ-12, the full POP-Q staging exam, urodynamics/imaging indications), anterior/middle compartment operative management (pessary, obliterative-vs-reconstructive and transvaginal-vs-transabdominal decisions, SSLF/USLS, anterior/ posterior colporrhaphy, midurethral slings, sacrocolpopexy, the FDA mesh-warning history and CARE trial data), and a dedicated multidisciplinary-approach section covering combined sacrocolpopexy+rectopexy technique, sequencing, and outcome data (TAPE scores). Does not duplicate the wiki's existing posterior-compartment content — cross-references it instead.
• sources/ASCRS Ch65 - Middle and Anterior Pelvic Compartment Issues for the Colorectal Surgeon.md — NEW, full structural summary including both offset findings (the predicted +14→+15 jump and the newly-discovered Part-divider-caused +15→+16 jump).
• conditions/Obstructed Defecation Syndrome (ODS).md — resolved its own explicitly-flagged open item ("no dedicated page yet exists for enterocele/sigmoidocele... revisit if a urogynecology- focused source is ever ingested") with a cross-reference to the new concept page. Frontmatter sources add Ch65.
• conditions/Rectocele.md — light edit: expanded its existing multidisciplinary cross-reference to point to the new concept page, including its "rectocele may be a result, not a cause, of ODS" point. Frontmatter sources add Ch65, updated: 2026-08-27.
• procedures/Rectal Prolapse Repair.md — light edit: cross-referenced the new concept page from both its ventral mesh rectopexy section (combined sacrocolpopexy+rectopexy detail) and its recurrent- prolapse multidisciplinary-re-evaluation note. Frontmatter sources add Ch65.
• conditions/Rectal Prolapse (Procidentia).md — light edit: cross-referenced the new concept page from its concomitant-POP paragraph. Frontmatter sources add Ch65, updated: 2026-08-27.
• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries updated, including both offset findings (with the new Part-divider mechanism explained) in index.md's Sources section.
• Research Priorities.md — five new entries added under a new "Pelvic organ prolapse (anterior/middle compartment)" section: Wu et al.'s lifetime-risk projection, the CARE trial, the OPTIMAL trial, Chughtai et al.'s mesh-infection combination study, and Watadani et al.'s combined sacrocolpopexy+rectopexy outcome study (the single most load-bearing citation for this wiki's multidisciplinary-surgery guidance, also referenced from Rectal Prolapse Repair).

Next up: Chapter 66 ("Pediatric Colorectal Disorders," Teeple EA, Azarow KS) opens Part VI: Miscellaneous and continues the sequential front-to-back ASCRS Textbook ingest — begins at PDF page 1073, book page 1089. Offset is now +16 (confirmed above against the copyright line, per the newly-confirmed Part-divider-caused jump).

[2026-08-27] Chapter 66 — Pediatric Colorectal Disorders

Read in full (book pages 1089-1103, PDF pages 1073-1087) before writing (Teeple EA, Azarow KS). Confirmed via the copyright-line cross-check that the offset is unchanged at +16 for this chapter ("© Springer Nature Switzerland AG 2022 1089").

Checked the Ch66/Ch67 boundary explicitly and found another +1 jump, to +17 — Ch67 ("Considerations for Geriatric Patients Undergoing Colorectal Surgery") begins at book page 1105 (copyright line "© Springer Nature Switzerland AG 2022 1105"). This is the standard mechanism, not a further Part divider: Ch66 ends on book page 1103, an odd page, forcing a dropped blank page before Ch67 can start on the next recto page. Sixth offset jump found across the ingest arc, and a return to the "chapter ends on odd page" pattern after the Part-divider-caused jump at Ch65/Ch66.

This chapter opens Part VI: Miscellaneous and surveys several distinct pediatric colorectal conditions in less depth than their adult counterparts receive elsewhere in the textbook. Rather than fragmenting into many thin pediatric-specific pages, all content was consolidated into one new umbrella page, following the same organizing precedent as Obstructed Defecation Syndrome (ODS) and General Postoperative Complications.

• conditions/Pediatric Colorectal Disorders.md — NEW. Covers Hirschsprung's disease (three presentation windows, calretinin-based diagnosis, the pediatric-specific caveat that anorectal manometry/RAIR is unreliable under 12 months of age, the three classic operations — Swenson, Soave with the Boley modification, Duhamel — a complication workup ladder, HAEC epidemiology and microbiome research, and adult/long-term outcomes with a noted controversy over how optimistic they really are); colonic duplications (epidemiology, embryologic theories, the Currarino triad, excision-vs-fenestration decision-making); pediatric constipation (natural history, HD-exclusion workup, sitz marker studies/colonic manometry, surgical options including the pediatric-specific caveat that SNS for constipation alone has a high failure rate, constipation-associated volvulus and perforation); pediatric rectal prolapse (90% conservative resolution under age 4, cystic fibrosis screening, a 2018 APSA sclerotherapy survey with agent-specific cure rates — 30% saline, 5% phenol in almond oil, 70% ethanol — Thiersch/linear cauterization/modified Thiersch, and operative options incl. Ekehorn's rectosacropexy); perianal abscess and fistula-in-ano (a distinctly different pediatric epidemiology — age/sex distribution, organism-sex association — and an explicitly unsettled operative-vs-nonoperative literature, plus IBD/immunosuppression red flags for recurrent fistula beyond infancy); anal fissure (anterior-midline predominance in females, three GTN RCTs with conflicting results, Botox-vs-myectomy comparison data, and a sphincter-surgery caution specific to small children); cecostomy/ACE (MACE technique history, percutaneous alternatives, comparative trade-offs, success prediction, and adjunctive SNS use); and ARM/HD transitional care to adult colorectal surgery (severity spectrum, fistula-level-correlated outcomes, and a structured age-12-to-21 transition process). Cross-references the wiki's existing adult-population pages throughout (Fecal Incontinence, Constipation, Rectal Prolapse Repair, Rectal Prolapse (Procidentia), Anorectal Abscess, Anal Fistula, Anal Fissure, Anorectal Physiology Testing, Sexual Function After Colorectal Surgery, Low Anterior Resection Syndrome (LARS)) rather than duplicating shared adult-surgery material.
• sources/ASCRS Ch66 - Pediatric Colorectal Disorders.md — NEW, full structural summary including both offset findings.
• conditions/Constipation.md, conditions/Anal Fissure.md, conditions/Anorectal Abscess.md — light edits adding a reciprocal cross-reference to the new pediatric page in each Related pages section. Frontmatter sources add Ch66, updated: 2026-08-27 on all three.
• conditions/Conditions.md, index.md, sources/Sources.md — landing page entries updated, including both offset findings in index.md's Sources section.
• Research Priorities.md — four new entries added under a new "Pediatric colorectal disorders" section: Hintz et al.'s sclerotherapy systematic review, the Kenny et al. GTN RCT (whose null result conflicts with two other cited GTN trials), Afsarlar et al.'s perianal abscess/fistula outcomes study, and Christison-Lagay et al.'s nonoperative-management study.

Next up: Chapter 67 ("Considerations for Geriatric Patients Undergoing Colorectal Surgery," Saur NM, Bass Wilkins K) continues the sequential front-to-back ASCRS Textbook ingest, still within Part VI: Miscellaneous — begins at PDF page 1088, book page 1105. Offset is now +17 (confirmed above against the copyright line, per the newly-confirmed Ch66/Ch67 jump).

2026-08-27 — Chapter 67: Considerations for Geriatric Patients Undergoing Colorectal Surgery

Continued the sequential ASCRS Textbook ingest (still within Part VI: Miscellaneous), per standing "Continue locally" instruction given the device bridge's continued unavailability this session.

Extracted and read the full chapter (PDF pp.1088-1099, book pp.1105-1116). A dedicated geriatric- surgery chapter (Saur NM, Wilkins KB), substantially deeper on this population than the existing elderly/frailty content already sourced from ASCRS Ch6/Ch7 on Preoperative Evaluation & Perioperative Risk Optimization and Enhanced Recovery After Surgery (ERAS). Checked both pages before writing — confirmed their existing frailty/prehabilitation/ERAS-in-elderly content is real but general-perioperative-medicine- level, while this chapter adds geriatric-oncology-specific screening tools, a full functional- recovery/PROM framework, and — uniquely — an interdisciplinary task force's personalized rectal- cancer treatment algorithm for geriatric patients. Decided on a new dedicated concept page rather than folding into either existing page, given this depth and the unique rectal-cancer-specific content that doesn't belong on either generalist page.

Files created:

• concepts/Geriatric Considerations in Colorectal Surgery.md — NEW. Sections: Frailty screening (Table 67.1's eight tools — ECOG PS, ADLs, Mini-Cog, fTRST, TUG, G8, NRS, ASA, CACI); Domains of geriatric assessment; Prehabilitation (Minnella et al.'s poor-baseline-walking-capacity-benefits- most finding, the ~30% non-responder rate, Gillis et al.); Surgical considerations (ERAS, MIS, emergency surgery and the fTRST's ED-setting validation via Zattoni et al., explicit guidance against age-based bias toward palliative lesser operations); Postoperative management (Shahrokni et al.'s geriatric-comanagement mortality comparison, delirium prevention OR 0.47); Functional recovery and patient-reported outcomes (GOSAFE study, ICHOM PROM domains via Doolin et al., LARS score/ Cleveland Clinic Fecal Incontinence Score as validated instruments, colostomy-vs-coloanal- anastomosis decision-making for poor baseline sphincter tone); and Personalized Treatment of Rectal Cancer (a 29-member interdisciplinary task force's — Montroni et al. — expert consensus: frailty-based MDT stratification, patient optimization, surgical treatment incl. TME approach selection and local-excision-after-radiation restriction, treatment of locally advanced disease incl. watch and wait and no-adjuvant-chemotherapy guidance, treatment of synchronous liver metastases, outcomes/ERAS/PROMs/healthcare-cost recommendations, a fit-vs-frail treatment algorithm, and life-expectancy data showing modern surgical outcomes now approach that of peers without rectal cancer).

• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries added, including the confirmed offset (+17 unchanged) and no-jump finding at the Ch67/Ch68 boundary in index.md's and Sources.md's Sources sections.
• Research Priorities.md — six new entries added under a new "Geriatric colorectal surgery" section: Minnella et al. (prehabilitation response), the GOSAFE study, Shahrokni et al. (geriatric comanagement), Zattoni et al. (fTRST ED validation), Hshieh et al. (delirium-prevention meta-analysis), and Montroni et al. (the interdisciplinary task force recommendations — flagged as the single most load-bearing citation in the chapter).

Next up: Chapter 68 ("Healthcare Economics," Peters WR, deBeche-Adams T) continues the sequential front-to-back ASCRS Textbook ingest, still within Part VI: Miscellaneous — confirmed starting at PDF page 1100, book page 1117. Offset remains +17 (confirmed above, no jump at the Ch67/Ch68 boundary).

2026-08-27 — Chapter 68: Healthcare Economics

Continued the sequential ASCRS Textbook ingest per the standing "Continue locally" instruction — the device bridge remains unavailable (checked again before starting this chapter; still not connected).

Extracted and read the full chapter (PDF pp.1100-1109, book pp.1117-1126). A genuine outlier relative to every other chapter ingested so far: a practice-management/health-policy chapter (Peters WR, deBeche-Adams T) rather than clinical content — US healthcare spending in global/OECD context, US healthcare finance (Medicare/Medicaid/employer/individual insurance), current health-policy debates (ACA litigation, underinsurance, surprise billing, rural hospital closures), MACRA/MIPS/Advanced-APM physician reimbursement, and coding systems (ICD-10, CPT® categories/modifiers/add-on/unlisted codes, DRG, claims-to-payment flow). No existing wiki page covered this material (confirmed by search — no practice-management or health-policy page exists), so no reconciliation was needed.

Files created:

• concepts/Healthcare Economics & Surgical Coding.md — NEW. Full structural summary per the chapter's five main sections; explicitly flagged as standing largely apart from the rest of the clinical wiki with minimal cross-linking attempted.
• sources/ASCRS Ch68 - Healthcare Economics.md — NEW, full structural summary and wiki-disposition rationale.

Files edited:

• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries added, including the confirmed offset (+17 unchanged) and no-jump finding at the Ch68/Ch69 boundary.
• Research Priorities.md — no new entries; this chapter's citations are health-policy/health- services-research sources rather than clinical trials, and none rose to the level of a specific load-bearing quantitative claim warranting independent verification beyond what's already flagged in the page's own Open items.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 213 total files (211 → 213: one new concept page, one new source page; no other pages cross-referenced given the topical distance from clinical content). Wikilink resolution re-checked (pipe-aware, alias-aware incl. frontmatter aliases:, newline-detecting) — 0 broken links beyond the 5 established log.md false positives, 0 newline-embedded wikilinks.

Next up: Chapter 69 ("Ethical Considerations (Conflict of Interest, Surgical Innovation, and End of Life)," Buie WD, MacLean AR) continues the sequential front-to-back ASCRS Textbook ingest, still within Part VI: Miscellaneous — confirmed starting at PDF page 1110, book page 1127. Offset remains +17 (confirmed above, no jump at the Ch68/Ch69 boundary).

2026-08-27 — Chapter 69: Ethical Considerations (Conflict of Interest, Surgical Innovation, and End of Life)

Continued the sequential ASCRS Textbook ingest per the standing "Continue locally" instruction. The device bridge briefly surfaced new browser-automation tool names mid-chapter, suggesting a reconnection attempt, but get_device_info still failed (first a 60-second timeout naming the bound device, then the standard "not connected" error) — treated as still unavailable, retried per protocol, then continued without pausing to ask again.

Extracted and read the full chapter (PDF pp.1110-1121, book pp.1127-1138). The second consecutive non-clinical Part VI chapter (Buie WD, MacLean AR): conflict of interest in surgical research (classification, industry-sponsorship bias evidence incl. the Vioxx case study, Cherla et al.'s surgeon-vs-OPD discordance finding, four management strategies), the ethics of surgical innovation (the taTME urethral-injury/Norway-moratorium cautionary case study, the Society of University Surgeons and IDEAL Collaboration oversight frameworks, innovation-specific informed consent, outcomes-tracking obligations), and end-of-life surgical decision-making (communication incl. the SUPPORT trial and "clinical momentum," prognostication incl. surrogate-decision-maker miscalibration data, the four ethical principles, shared decision-making, double effect, withdrawal-of-care criteria, cultural variation). No existing wiki page covered any of these three ethics domains (confirmed by search), so no reconciliation was needed beyond the taTME cross-reference.

2026-08-27 — Chapter 70: Welcome to Litigation

Continued the sequential ASCRS Textbook ingest per the standing "Continue locally" instruction; the device bridge remains unavailable (checked twice before starting, both attempts failed with the standard "not connected" error).

Extracted and read the full chapter (PDF pp.1122-1143, book pp.1139-1160). The third consecutive non-clinical Part VI chapter, written by a practicing malpractice trial attorney (Ames DK) rather than a physician: malpractice risk epidemiology, the three stages of civil litigation (initiation, discovery, trial), extensive deposition-technique guidance, and the legal standard for surgical negligence. No existing wiki page covered litigation procedure, so no reconciliation was needed beyond a light cross-reference to the informed-consent/battery distinction shared with Ch69's page.

Files created:

• concepts/Medical Malpractice Litigation.md — NEW. Full structural summary across the three litigation stages, with the chapter's teaching-points/worked-example content (the "emergency" ambiguous-term deposition exchange, the estimate-vs-guess table example) preserved as illustrative detail.
• sources/ASCRS Ch70 - Welcome to Litigation.md — NEW, full structural summary and wiki-disposition rationale.

Files edited:

• concepts/Surgical Ethics (Conflict of Interest, Innovation & End-of-Life Care).md — light edit: added a reciprocal cross-reference to the new page (Related pages). Frontmatter sources add Ch70.
• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries added, including the confirmed offset (+17 unchanged) and no-jump finding at the Ch70/Ch71 boundary.
• Research Priorities.md — no new entries; the chapter's sole substantive citation (a 2011 NEJM malpractice-risk-by-specialty study) is background epidemiology rather than a load-bearing clinical finding, and the remaining citations are California Civil Jury Instructions and case law, not independently verifiable studies.

2026-08-27 — Chapter 71: Quality

Continued the sequential ASCRS Textbook ingest per the standing "Continue locally" instruction; the device bridge remains unavailable (checked twice before starting, both attempts failed with the standard "not connected" error).

Extracted and read the full chapter (PDF pp.1144-1152, book pp.1161-1169). The fourth consecutive non-clinical Part VI chapter (Wick EC, Etzioni DA), but the first to connect directly to existing clinical content: the Donabedian structure/process/outcomes quality framework, quality-measurement tradeoffs (registry vs. administrative data, evaluative vs. transactional data, composite vs. single outcomes, risk adjustment), ACS-NSQIP's history and structure, the National Accreditation Program for Rectal Cancer (NAPRC), alternative payment models/bundled payments, and organizational safety culture. Checked existing pages first: Total Mesorectal Excision (TME) & Sphincter-Sparing Resection already briefly mentioned NAPRC (MRI staging, tumor board requirement), and General Postoperative Complications and several other pages already cite ACS-NSQIP data extensively — decided to create a new dedicated page and cross-link both, extending rather than duplicating that existing content.

Files created:

• concepts/General Postoperative Complications.md — light edit: added a cross-reference noting the new page covers NSQIP's own structure/history, which this page cites extensively as a data source without describing. Frontmatter sources add Ch71.
• concepts/Concepts.md, index.md, sources/Sources.md — landing page entries added, including the confirmed offset (+17 unchanged) and the jump to +18 at the Ch71/Ch72 boundary — the seventh offset jump found across this ingest arc, via the standard odd-ending-page mechanism (Ch71 ends on book page 1169).
• Research Priorities.md — no new entries; this chapter's citations are health-services-research/ policy sources (SCIP-compliance studies, the bariatric-accreditation Medicare analysis) rather than clinical trials with individually load-bearing quantitative claims distinct from what's already flagged in the page's own Open items.

Frontmatter validated via Python/yaml across all **/*.md files under wiki/ — 0 bad, 219 total files (217 → 219: one new concept page, one new source page; two pages — one procedure, one concept — lightly cross-referenced).

2026-08-27 — Chapter 72: Practice Management (FINAL CHAPTER)

Continued the sequential ASCRS Textbook ingest per the standing "Continue locally" instruction; the device bridge remains unavailable (checked before starting — get_device_info failed with the standard "not connected" error; briefly, new mcp__remote-devices__Claude_Browser__* tool names appeared as they did once earlier in this run, but disappeared again on the next check without a successful connection).

Extracted and read the full chapter (PDF pp.1153-1170, book pp.1171-1188; 909 lines of extracted text). This is the seventy-second and final chapter of the ASCRS Textbook of Colon and Rectal Surgery, 4th edition — a page-by-page scan confirmed the book's back-of-book Index begins immediately at PDF page 1171/book page ~1190, with no Chapter 73. The fifth and last of the non-clinical Part VI: Miscellaneous chapters (Rea JD, Cohen JL): practice models (independent single-specialty vs. multispecialty group structures, private-equity/MSO investment with EBITDA-multiple valuation, employed models — now exceeding 47% of physicians nationally — and practice-acquisition considerations); finance and coding basics; RVU-based physician compensation (the three RVU components — work, practice expense, malpractice expense — and academic vs. private-practice compensation structures); developing a referral base via the "four A's" (availability, affability, ability, accountability); marketing (digital/social media dominance over print, SEO, online reputation management on Healthgrades/Vitals); office setup and staffing efficiency; office-based procedures (Table 72.1's CPT-code/global-period/Medicare-reimbursement detail, Table 72.2's clinic supply list); ancillary services and Stark Law/Anti-Kickback constraints (the 12 designated health services categories, the in-office ancillary services exception, fair-market-value/commercial-reasonableness standards); ambulatory surgery centers (Certificate of Need laws, JCHO accreditation, CLIA certification); leadership-role development; and closing reflections via the "quadruple aim" (patient/customer experience, quality, cost efficiency, provider wellness). Checked existing pages first: no wiki page covered practice-operations, compensation, referral-building, marketing, or ASC/ancillary-service regulatory content — consistent with the pattern for the four preceding non-clinical chapters, this is genuinely new topical ground.

Files created:

• concepts/Practice Management for Colorectal Surgeons.md — NEW. Full structural summary across practice models, finance/compensation, referral development, marketing, office setup and office-based procedures, ancillary services/Stark Law, ambulatory surgery centers, leadership, and the quadruple aim.

This concludes the sequential, front-to-back ingest of the ASCRS Textbook of Colon and Rectal Surgery, 4th edition. All 72 chapters have now been read in full and reconciled into the wiki, spanning this multi-session project from Chapter 1 (anatomy/embryology) through Chapter 72 (practice management) — the entire clinical core (anatomy, physiology, benign and malignant colorectal disease, IBD, functional disorders, pelvic floor disorders, surgical technique across the full range of colorectal procedures, perioperative care, complications, and special populations) plus, in the final stretch (Ch68-72), the textbook's non-clinical Part VI chapters on healthcare economics, surgical ethics, medical malpractice litigation, quality measurement, and practice management. The book's back-of-book Index (immediately following Ch72) is reference material, not narrative content, and is not planned for separate ingest. Remaining open work is entirely mechanical: (1) reconnect the device bridge and push all pending files from Chapters 60-72 in one batch via the SendUserFile→ device_commit_files pattern, verify "rejected":[], then push log.md again to correct its "Push status" lines for all thirteen pending chapter entries; and (2) the wiki's ongoing general-maintenance mode going forward — cross-linking refinement, Research Priorities.md follow-up as literature develops, and incorporation of any future source material the user adds outside the ASCRS textbook sequence.

2026-08-27 — Combined push: Chapters 60-72

The device bridge reconnected. Diffed the full local wiki (221 files) against the live vault on Stephen's Mac (device_list_dir, recursive) by filename and byte size — the vault's wiki/ folder was last synced through Chapter 59, confirming all work from Chapter 60 (Rectal Prolapse) through Chapter 72 (Practice Management, the textbook's final chapter) had been queued locally exactly as each chapter's own log entry described.

The diff found 46 files to push: 22 new (8 new concept pages — Sexual Function After Colorectal Surgery, Pelvic Organ Prolapse, Pediatric Colorectal Disorders as a condition page, Geriatric Considerations, Healthcare Economics & Surgical Coding, Surgical Ethics, Medical Malpractice Litigation, Surgical Quality Measurement & Improvement, and Practice Management for Colorectal Surgeons — plus 13 new ASCRS Ch60-ASCRS Ch72 source pages) and 24 edited (landing pages index.md, Concepts.md, Conditions.md, Procedures.md, Sources.md, Research Priorities.md, log.md itself, and reconciled/cross-referenced condition and procedure pages — Anal Fissure, Anorectal Abscess, Constipation, Fecal Incontinence, LARS, Obstructed Defecation Syndrome, Rectal Cancer, Rectal Prolapse, Rectal Prolapse Repair, Rectocele, SRUS, APR, TME & Sphincter-Sparing Resection, Anorectal Physiology Testing, Enhanced Recovery After Surgery, General Postoperative Complications, and Preoperative Evaluation & Perioperative Risk Optimization).

Pushed via the two-phase pattern: SendUserFile on all 46 files to obtain file_uuids, then device_commit_files with expectedMtimeMs guards (sourced from the fresh device_list_dir listing) on the 24 pre-existing files being overwritten. Result: "rejected":[] — all 46 files written successfully in a single call. The 13 individual "Push status" lines above (Chapters 60 through 72) have been corrected in place (strikethrough + Pushed, per established convention) to point to this entry.

This closes out the device-sync backlog that accumulated during the bridge's extended disconnection. The vault on Stephen's Mac now reflects the complete, validated state of the sequential ASCRS Textbook ingest — all 72 chapters, 221 wiki files, 0 frontmatter errors, 0 broken wikilinks beyond the 5 established false positives in this log. The sequential full-textbook ingest project is complete both locally and on-device.
