Suppurative granulomatous inflammation in the ileo-anal pouch.

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is commonly performed for medically refractory ulcerative colitis (UC), however with multiple possible complications, most notably pouchitis, cuffitis, Crohn's disease of the pouch and irritable pouch syndrome. We present a unique case of suppurative granulomatous inflammation in the ileal pouch mucosa, most likely infective in nature, that is unrelated to recognised causes of such pathology, especially yersiniosis.
