Pelvic pouch cancers associated with inflammatory bowel disease

Abstract

Patients with inflammatory bowel disease who undergo ileal pouch-anal anastomosis are at finite risk of developing neoplasia of various parts of the pouch. In this review article, we will describe different forms of pelvic pouch-related cancers, with a focus on diagnosis and management of small bowel adenocarcinomas of the pouch body, rectal neoplasia of the rectal cuff and anal transition zone, small intestinal lymphoma of the pouch, and anal dysplasia and squamous cell cancer of the anal canal.
