Perioperative Factors During Ileal Pouch-Anal Anastomosis Predict Pouchitis

Abstract

Patients with symptomatic, biopsy-confirmed pouchitis have worse long-term outcomes than those without pouchitis. This complication is associated with specific pre- and intraoperative factors. Histological pouchitis incidentally found on surveillance biopsy in asymptomatic patients is of no clinical relevance and does not influence outcome. Identification of these preoperative factors associated with the subsequent development of pouchitis will strengthen patient counseling and may facilitate risk stratification.
