Open versus laparoscopic (assisted) ileo pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis.

Restorative proctocolectomy with ileo pouch anal anastomosis (IPAA) is the main surgical treatment for patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). With the advancements of minimal-invasive surgery this demanding operation is increasingly being performed laparoscopically. Therefore, the presumed benefits of the laparoscopic approach need to be systematically evaluated.
