Pouchitis Associated With Pelvic Radiation for Prostate Cancer.

Radiation therapy is a viable option in managing potentially life-threatening malignancies including prostate cancer. It is known that pelvic radiation can result in injury of the distal large bowel with the development of radiation proctitis. Despite reports from retrospective studies, there is a lack of direct endoscopic and histologic evidence of external pelvic radiation injury to the ileal pouch-anal anastomosis. We present a case of a 68-year-old male with pouchitis resulting from pelvic radiation for prostate cancer.
