Extensive Disease and Exposure to Multiple Biologics Precolectomy Is Associated with Endoscopic Cuffitis Post-Ileal Pouch-Anal Anastomosis in Patients With Ulcerative Colitis.

Introduction: To better inform the risk of cuffitis in patients with ulcerative colitis (UC), we aimed to identify its occurrence and associated precolectomy factors in a large multicenter cohort of patients who underwent restorative proctocolectomy (RPC) with stapled ileal pouch-anal anastomosis (IPAA).
Methods: This study was a retrospective cohort analysis of individuals diagnosed with UC or indeterminate colitis who underwent RPC with IPAA for refractory disease or dysplasia at Mount Sinai Hospital or the University of Chicago followed by at least 1 pouchoscopy with report of the pouch-anal anastomosis. The primary outcome was cuffitis defined as ulceration of the cuff as reported in each pouchoscopy report.
Results: The pouch-anal anastomosis was mentioned in the pouchoscopy reports of 674 patients, of whom 525 (77.9%) had a stapled anastomosis. Among these, cuffitis occurred in 313 (59.6%) patients a median of 1.51 (interquartile range 0.59-4.17) years after final surgical stage. On multivariable analysis, older age (hazard ratio [HR], 1.01; 95% confidence interval [CI], 1.01-1.02), extensive disease (HR, 1.34; 95% CI, 1.01-1.78), exposure to biologics before colectomy (HR, 2.51; 95% CI, 1.93-3.27), and exposure to at least 2 or more biologics before colectomy (HR, 2.18; 95% CI, 1.40-3.39) were significantly associated with subsequent cuffitis.
Conclusions: In this multicenter study of patients who underwent RPC with stapled IPAA and at least 1 follow-up pouchoscopy, cuffitis occurred in approximately 60% and was significantly associated with extensive disease and exposure to multiple biologics precolectomy.
