Curative endoscopic treatment of intussusception due to a giant colonic lipoma using a wedged balloon and ligation with detachable snares

Abstract

A 67-year-old woman presented with symptoms of bowel obstruction. Radiographic and ultrasonographic findings suggested colo-colonic intussusception caused by a colonic lipoma. Colonoscopy with an endoscope tip balloon was performed for reduction. The intussusception was partially reduced by injecting dilute contrast media with a wedged inflated balloon at the endoscope tip. For definitive treatment of the polyp, ischemia was induced using a detachable snare. The abdominal pain well improved after endoscopic treatment. However, ultrasonography suggested a residual lesion. Another detachable snare was applied to the stalk on day 6. A large amount of dark-red necrotic tissue was passed per anus the following day. One month later, complete scarring of the site was confirmed colonoscopically. This is the first report of curative endoscopic treatment of an intussusception due to a giant colonic lipoma with detachable snares after the reduction with a wedged balloon of colonoscope tip.
