In women desiring future pregnancy after IPAA, is a W pouch or J pouch preferred for obstetric outcomes

What is known

- Randomized and meta-analytic J- vs W-pouch comparisons report on function and complications (leak, stricture, sepsis, obstruction), not obstetric outcomes. ^1–4 - Functional data suggest lower bowel frequency and antidiarrheal use with W/S vs J pouches, though maturation may equilibrate this difference. ^1,2 - Pregnancy/delivery series in IPAA patients report no pouch-related complications during pregnancy and recommend cesarean only for obstetric indication, without design-based stratification. ^5,6 - Cesarean is often preferred after IPAA to reduce anal sphincter and perianal injury, independent of pouch type. ^7,8

What is unknown / caveats

- No retrieved study compares obstetric outcomes by J vs W pouch design - Pregnancy series are small, older, and pool pouch types - Whether the larger-capacity W pouch offers any pregnancy-specific advantage is untested in the retrieved evidence.
