The most common operation performed to treat ulcerative colitis is ileal pouch/anal anastomosis (IPAA). In this multistage procedure, a diverting ileostomy is performed and an ileal pouch is created and anastomosed directly to the anus, with complete removal of the rectal mucosa. After the ileoanal anastomosis is healed, the ileostomy is taken down, and flow through the anus is reestablished.
