Complete rectosigmoid prolapse in a patient with familial adenomatous polyposis.

摘要

Colonoscopy in a 23-year-old woman to evaluate her for familial adenomatous polyposis syndrome revealed thousands of colonic adenomas. A few hours after the procedure, the patient had a bowel movement followed by a massive, full-thickness, rectosigmoid prolapse (A). The prolapsed segment of the colon showed no signs of ischemia. The patient was placed in the left lateral position and was sedated with 4 mg midazolam given intravenously. The prolapsed colon was manually reduced with gentle maneuvers. The patient had no recurrence of the prolapse over the following days.
