The ileal pouch anal anastomosis (IPAA) surgery is the most common pelvic pouch (see also, S, W, Kock pouch) surgery performed and most typically used to treat those with ulcerative colitis and inherited conditions such as familial adenomatous polyposis (FAP).

When successful the stoma is reversed and patients return to expelling waste through the anus.
