Early surgery and mortality in toxic megacolon

What is known

• Colonic perforation complicating toxic megacolon carried ~20% mortality versus ~4% without perforation in a Crohn's colon review. ¹
• Early surgery without perforation was reported at 2–8% mortality versus ~40% when colectomy followed perforation. ²
• Authors attributed most perforations and deaths to delay before operation rather than the operation itself, urging earlier intervention. ³
• Series-level mortality fell over successive time periods (e.g., 55%→14%, 32%→14%) as management and earlier surgery evolved, though confounded by improved resuscitation and TPN. ^4,5

What is unknown / caveats

• All evidence is small retrospective single-center series from the 1980s–2010s plus case reports; no RCT or comparative cohort of early vs delayed surgery
• Mixed UC and Crohn's populations; temporal mortality gains confounded by concurrent advances in resuscitation and TPN
• The mortality gap tracks with perforation status rather than a clean early-vs-late surgical timing comparison, so causal attribution to timing itself is inferential.
