title: Sigmoid perforation and bucket-handle tear of the mesocolon after bicycle handlebar injury: a case report and review of the literature.
abstract: We describe an unusual case of sigmoid colon perforation secondary to a bicycle handlebar injury. Because the patient presented 2 days after the initial injury, we suspected that the colon perforation was not the immediate result of the bicycle accident but, rather, was secondary to devascularization. At operation, we found a bucket-handle tear of the colonic mesentery, which was the patient's primary injury and cause of the perforated colon.
