title: Mesocolon laceration following colonoscopy.
abstract: Colonoscopic examination is a safe procedure, however, unexpected complications can sometimes occur. Bleeding and perforation of the colon have been reported as the most common complications. Hemoperitoneum after colonoscopy is an unusual complication, but it may be catastrophic. We report on a 20-year-old man who experienced left low quadrant pain after undergoing colonoscopy. Hemoperitoneum was diagnosed using abdominal CT. A laparoscopic exploration was urgently performed, revealing a lacerated mesocolon of the descending colon. Bleeding of the injured site was controlled without complication. The patient recovered fully without signs of recurrent bleeding. This report implies that if the patient has persistent abdominal pain after undergoing colonoscopy, we should consider hemoperitoneum as one of the causes. To the best of our knowledge, no case of isolated laceration of the mesocolon of the descending colon after colonoscopy has been reported.
