Citation: Galandiuk S, Netz U, Morpurgo E, Tosato SM, Abu-Freha N, Ellis CT. Chapter 52: Colon and Rectum. In: Sabiston Textbook of Surgery, 21st ed. Elsevier; pp. 1378–1389 (this chunk).
Source type: Textbook chapter — reference source, not a primary study. See Sabiston Ch52 - Diverticular Disease, Obstruction & Pseudo-Obstruction for the general note on how this chapter is used in the wiki.
This is chunk 5 of the chapter (chunk 1: diverticular disease/obstruction/Ogilvie syndrome; chunk 2: IBD; chunk 3: infectious/ischemic colitis; chunk 4: colorectal neoplasia/colon cancer surgery). Chunk 6 (the last one) will cover Pelvic Floor Disorders and Constipation, which this chunk overlaps into by a page or two while finishing rectal cancer content.
Scope of this chunk
Pages 1378–1389: preoperative evaluation and staging of rectal cancer, local excision, the history/rationale behind TME and preoperative chemoradiation, low anterior resection, sphincter- sparing surgery, transanal TME, abdominoperineal resection, special circumstances (synchronous cancers, short residual colon), anastomotic and other surgical complications, low anterior resection syndrome, and postoperative surveillance/adjuvant chemotherapy by stage.
Filing
- Expanded the existing Rectal Cancer stub page — preoperative evaluation, staging, the TME/CRM/downstaging history, survival by stage, surveillance, and adjuvant chemotherapy.
- New procedure pages: Local Excision of Rectal Neoplasms, Total Mesorectal Excision (TME) & Sphincter-Sparing Resection (LAR, coloanal anastomosis, taTME grouped together), Abdominoperineal Resection (APR).
- New concept page: Colorectal Anastomotic Complications (leak, necrosis, bleeding, twisting, strictures — cross-cutting, not rectal-specific).
- New condition page: Low Anterior Resection Syndrome (LARS).
Relevance
This chunk connects several previously-separate threads in the wiki: the existing Total Neoadjuvant Therapy (TNT) concept page (from the Boublikova review) now has surgical and staging context to sit alongside; the Colorectal Cancer Staging (TNM) page gets its rectal- specific staging modalities (ERUS/MRI); and the previously-stubbed Rectal Cancer page becomes a real synthesis page rather than a TNT-only placeholder. As with prior chunks, none of the specific figures (survival percentages, complication rates, chemotherapy trial results like the IDEA duration analysis) are independently verified against primary literature here — the adjuvant chemotherapy section in particular summarizes several specific trials (FOLFOX/CAPOX duration, Bockelman meta-analysis) that would be worth ingesting directly if a specific treatment decision is on the line.
