  • 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.
