Colonoscopy is regarded as a relatively safe procedure and is widely performed. However, complications such as bleeding, perforation, and coagulation syndromes can occur during colonoscopy. Although bowel perforation is as rare as 0.4-1.9% of cases, it is the most serious and awful adverse event which can lead to a death. Colon perforation may occur as either intraperitoneal or extraperitoneal, or in combination. Right subdiaphragmatic free air suggests intraperitoneal perforation while pneumoretroperitoneum, pneumomediastinum, pneumopericardium, and subcutaneous emphysema suggest extraperitoneal perforation. Combined intraperitoneal and extraperitoneal perforation is very rare. Herein, we present a case of combined intraperitoneal and extraperitoneal colon perforation which manifested as pneumoretroperitoneum, pneumomediastinum, pneumopericardium, and subcutaneous emphysema. The lesion was closed with endoscopic clipping.

Colon perforation is an uncommon but serious complication of colonoscopy. It may occur as either intraperitoneal or extraperitoneal perforation or in combination. The majority of colonic perforations are intraperitoneal, causing air and intracolonic contents to leak into the peritoneal space. Rarely, colonic perforation can be extraperitoneal, leading to the passage of air into the retroperitoneal space causing pneumoretroperitoneum, pneumomediastinum, pneumopericardium, pneumothorax, and subcutaneous emphysema. A literature review revealed that 31 cases of extraperitoneal perforation exist, out of which 20 cases also reported concomitant intraperitoneal perforation. We report the case of a young female with a history of ulcerative colitis who developed combined intraperitoneal and extraperitoneal perforation after colonoscopy. We also report the duration of onset of symptoms, clinical features, imaging findings, site of leak, and treatment administered in previously reported cases of extraperitoneal colonic perforation.
