ASCRS Ch08 — General Postoperative Complications

Citation: Chu DI, Maron DJ. "General Postoperative Complications." In: Steele SR, et al. (eds.), The ASCRS Textbook of Colon and Rectal Surgery, 4th ed. Springer Nature Switzerland AG; 2022. pp. 141–155 (PDF pp. 154–168 of the combined textbook file).

Type: Specialty textbook chapter (reference/background, not primary literature).

Scope

Eighth chapter of the sequential full-textbook ingest (see ASCRS Ch01 - Anatomy and Embryology for the ingest's scope/plan). A cross-cutting overview of postoperative complication epidemiology, risk factors (non-modifiable and modifiable), risk calculators (POSSUM, APACHE, ACS-NSQIP), and management by organ system in ACS-NSQIP-ranked order of frequency: gastrointestinal (ileus, postoperative small bowel obstruction), hematologic (bleeding/transfusion, presacral bleeding, venous thromboembolism), infectious (SSI, wound dehiscence, UTI, C. diff — anastomotic leaks explicitly deferred to ASCRS Ch10), pulmonary (respiratory failure, pneumonia, aspiration), renal (AKI, postoperative urinary retention), cardiac (MI, atrial fibrillation), and neurological (perioperative stroke, sexual dysfunction, postoperative delirium).

Key content

Full synthesis written into the new concept page General Postoperative Complications rather than summarized twice here — the first genuinely new cross-cutting topic since Ch7's ERAS page, organizing complication management by organ system across the whole textbook rather than by disease or procedure. Extends several existing pages with quantified detail rather than duplicating them: Total Mesorectal Excision (TME) & Sphincter-Sparing Resection's qualitative sexual-dysfunction mention gains specific incidence figures; Abdominoperineal Resection (APR)'s previously-flagged open item on sexual/urinary dysfunction is partially addressed; Infectious Colitis's C. diff content gains a surgical-patient-specific incidence figure; and Colorectal Anastomotic Complications gains a forward-pointer noting the source chapter's own deferral of leak detail to ASCRS Ch10.

Limitations

• Textbook chapter, not primary literature; most figures (ACS-NSQIP complication rates, individual study risk ratios/odds ratios, sexual dysfunction incidence) are drawn from cited studies the chapter authors summarize, not independently verified against the primary sources.
• The chapter explicitly declines to cover anastomotic leaks in depth, deferring to its own dedicated chapter (ASCRS Ch10) — not yet ingested, so this wiki's leak content remains Sabiston-sourced rather than ASCRS-sourced for now.
• Female sexual/genitourinary dysfunction data is thinner and more conflicting than the male data presented (a threefold IPAA infertility-risk finding from one meta-analysis is contradicted by a smaller retrospective comparison) — preserved as unresolved rather than adjudicated.

Relevance

Eighth entry in the ASCRS ingest, and the second chapter (after Ch7) to introduce a genuinely new cross-cutting topic rather than extending a single existing condition/procedure page. Creates General Postoperative Complications and adds targeted, quantified extensions to four existing pages (Total Mesorectal Excision (TME) & Sphincter-Sparing Resection, Abdominoperineal Resection (APR), Infectious Colitis, Colorectal Anastomotic Complications) — continuing the ingest's established de-duplication approach, including one case (anastomotic leaks) where the right move was explicitly not to duplicate content the source chapter itself defers elsewhere.
