Abstract:
Colonoscopy is generally a safe and effective means to detect, diagnose, and treat colonic abnormalities. Although the overall complication rate is low, the morbidity and mortality following perforation approach 50%. Here we present a case of a 49-year-old woman undergoing routine colonoscopy when she suffered bowel perforation and tension pneumoperitoneum. This is a seldom occurrence and may result following bowel perforation with the rapid accumulation of free air into the peritoneal cavity. It is a life-threatening complication and a surgical emergency.
