Endoscopic Treatment of Colo-Colonic Intussusception in a Patient with Peutz-Jeghers Syndrome.

A 19-year-old man with a history of Peutz-Jeghers syndrome (PJS) and two previous partial small bowel resections because of intussusception presented with lower abdominal pain. Computed tomography (CT) showed concentric multilayer and cord-like structures in the transverse colon. Colo-colonic intussusception was suspected and he was hospitalized. After two therapeutic enemas were unsuccessful, a colonoscopy was performed. The intussusception was reduced and a 40-mm transverse colon polyp with a thick stalk was resected. After the procedure, his abdominal pain was relieved and he was discharged on the sixth hospital day. This case and several previous reports suggest that PJS polyps with tumor diameter exceeding 30 mm and location in the transverse or sigmoid colon can cause intussusception. Endoscopic treatment should be considered for these lesions.
