Adverse Event

In patients with ulcerative or indeterminate colitis who undergo ileal pouch anal anastomosis and diverting loop ileostomy (IPAA) surgery* a short interval to loop ileostomy reversal will result in differences in complications and quality of life compared to a long interval to loop ileostomy reversal.

Aim #1: To compare the Comprehensive Complication Index (CCI), the incidence of postoperative complications, including total number of complications per patient, percent of patients with complications, and total number of ostomy-related complications per patient among IPAA patients who have their ileostomy reversed after a short interval compared to a long interval.

Aim #2: To compare the short vs. long interval groups on measures of health-related quality of life (PROMIS) and IPAA functional outcomes
