Ten Versus Fifteen Centimeter Pouch in IPAA Surgery

Ileal Reservoir Length and Functional Outcome in Ileal Pouch-anal Anastomosis

The aim of this randomized controlled trial is to compare outcome after construction of an ileal (J-shaped) reservoir of 10 versus 15 centimeters in primary ileal pouch-anal anastomosis surgery.

The primary aim of this randomized controlled trial is to compare functional outcome in terms of bowel function correlated with quality of life for patients who undergo primary ileal pouch-anal anastomosis surgery with an ileal (J-shaped) reservoir length of either 10 cm or 15 cm.

Secondary aims include health-related quality of life measures and postoperative complications.

Inclusion Criteria:

• Undergoing ileal pouch-anal anastomosis (IPAA) for ulcerative colitis or familial adenomatous polyposis (FAP) (implying a normal sphincter function as judged by history and clinical examination)
• Signed informed consent
• Able to perform both a small (10 cm) and medium-size (15 cm) pouch with adequate reach and no tension as determined subjectively by the surgeon intraoperatively
