Perforation of a Long-standing Ileocolonic Anastomosis During Colonoscopy

Colonoscopy is a valuable diagnostic and therapeutic procedure. Colonic perforation is a serious complication of colonoscopy that must be promptly recognized to limit morbidity and mortality. We present a 69-year-old woman who, during colonoscopy, had a perforation secondary to barotrauma of a long-standing ileocolonic anastomosis proximal to the point of colonoscopic intubation. To our knowledge, this is the first case report of a perforation of a well-established anastomosis proximal to the point of endoscope intubation during colonoscopy.
