A CASE OF AN ADULT INTUSSUSCEPTION CAUSED BY A SIGMOID COLON POLYP THAT WAS SUCCESSFULLY RESECTED BY ENDOSCOPY : A CASE REPORT AND LITERATURE REVIEW

Abstract

A 22-year-old female patient was admitted to our hospital with complaints of lower abdominal pain and hematochezia. A mass measuring 3 cm in diameter was detected outside of the anus. The mass was manually reducted into the rectum, which resulted in rapid relief of abdominal pain. Sigmoidoscopy revealed a polyp with a nodulous head in the sigmoid colon. An intussusception caused by the sigmoid colon polyp was strongly suspected. Polypectomy was performed, and the patient's postoperative course was uneventful during a 1-month follow-up period. An adult intussusception caused by a sigmoid colon polyp that is successfully resected with endoscopy is extremely rare. Here, we describe one such case and review the literature.
