title: Endoscopic treatment of a large colonic polyp as a cause of colocolonic intussusception in a child.
abstract: Colocolonic intussusception is an uncommon cause of intestinal obstruction in children. The most common type is idiopathic ileocolic intussusception. However, pathologic lead points occur approximately in 5% of cases. In pediatric patients, Meckel's diverticulum is the most common lead point, followed by polyps and duplication. We present a case of recurrent colocolonic intussusception which caused colonic obstruction in a 10-year-old boy. A barium enema revealed a large polypoid mass at the transverse colon. Colonoscopy showed a colonic polyp, 3.5 centimeters in diameter, which was successfully removed by endoscopic polypectomy.
