Stapled vs hand-sewn IPAA in PSC: pouch failure

What is known

• Most studies show a slightly better functional outcome after stapled anastomosis, especially regarding continence, while stapling may risk cuffitis. ¹
• Hand-sewn (manual) anastomosis with mucosectomy eradicates diseased tissue but carries an increased risk of leakage; the stapled cuff lowers incontinence risk. ²
• The double-stapled technique is associated with improved functional outcomes compared with the hand-sewn technique in the general IPAA population. ³
• In a PSC case-control series, hand-sewn anastomosis with mucosectomy was used more often in PSC patients (32%) than in the general pouch population (15%), and the authors' preferred approach was hand-sewn. ⁴

What is unknown / caveats

• No excerpt reports pouch failure rates by anastomotic technique in PSC specifically
• General-population functional/leak comparisons may not transfer to PSC patients
• The excerpts describe functional outcomes and leak risk but do not quantify pouch failure by technique, and none isolate this comparison within the PSC population.
