External resection of a giant sigmoid lipoma causing colonic intussusception and prolapse through the anal canal

We depict the case of an 80-year -old female patient who presented to us with a history of protruding mass per anum. Sigmoidoscopy revealed a large globular pedunculated polyp at 22 cm from the anal verge resulting in a sigmoidorectal intussusception. Endoscopic polypectomy was not technically possible due to the lar ge size of the polyp. At the time of prolapse the polyp was tied at its pedicle with thread and resected sur gically . The patient is asymptomatic on follow-up.
