Abstract

Background: Gaps exist in our understanding of the clinical course of pouch-related disorders.

Methods: We evaluated baseline disease activity and longitudinal treatment patterns among patients with inflammatory conditions of the pouch.

Results: Among 468 patients with an ileal pouch-anal anastomosis (IPAA), 94 (20%) had acute pouchitis, 96 (21%) had chronic pouchitis, and 192 (41%) had Crohn disease of the pouch. Following an IPAA, 38% of patients were treated with a biologic and 11% underwent inflammatory bowel disease- or bowel-related surgery.

Conclusions: Treatment patterns after IPAA indicate that pouch-related disorders have a significant impact on individual patients and the healthcare system.
