IPAA
Pronunciation: EYE-pah
Also written as: IPAA — ileal pouch-anal anastomosis
Surgical procedure creating a pouch from the ileum and connecting it to the anus after colectomy.
Full Definition
Ileal pouch-anal anastomosis (IPAA) is a reconstructive surgical procedure performed after total colectomy or proctocolectomy. The surgeon creates a reservoir or 'pouch' from the terminal ileum, which is then connected directly to the anus. This procedure allows patients to maintain continence and defecate through the natural route rather than requiring a permanent ostomy. IPAA is commonly performed in pediatric patients with ulcerative colitis or familial adenomatous polyposis. The procedure typically requires multiple stages and is associated with complications such as pouchitis, stricture formation, and functional issues.
