In patients with UC and chronic pouchitis refractory to maximal medical therapy, is pouch excision with permanent ileostomy or continued aggressive medical management preferred

What is known

- Chronic pouchitis unresponsive to conventional antimicrobial therapy should prompt evaluation for secondary causes including crohn's disease of the pouch before escalation. ¹ - Newer biologic agents have broadened the medical management of chronic pouchitis and crohn's of the pouch, offering options beyond antibiotics. ¹ - Surgical failure management includes a choice between permanent diversion with pouch in situ versus pouch excision, with dedicated quality-of-life comparisons in the literature. ^2,3 - Historically, chronic pouchitis leading to pouch excision was uncommon (reported <1% of pouch patients in older series), though modern chronic pouchitis requiring continuous therapy affects 5-15%. ^4–6

What is unknown / caveats

- Retrieved sources are narrative reviews, older surgical texts, and guidelines. No head-to-head trial of continued biologic therapy vs pouch excision - Quality-of-life outcomes for diversion vs excision are cited only as references, not with extractable comparative data - The retrieved evidence does not quantify which pathway yields better long-term outcomes in the truly refractory patient.
