RESUMEN
An intussusception in adulthood is an unusual cause of bowel obstruction. It accounts for up to 5% of all intussusception. Approximately 90% of cases are secondary to a definite lesion such as malignancy or lipoma. Most patients are asymptomatic and the lesion is often detected incidentally at colonoscopy, operation and autopsy. Strangulated intussuscetion is a rare case and also requires emergency operation. A 32-year-old woman visited our emergency room because of severe epigastric pain. Abdominal CT revealed a low density mass in bowel loop and distended small bowel loops filled with fluid. Colonoscopic finding showed huge purple-colored coil-spring lesion in the ascending colon. From this findings, we diagnosed a strangulated intussusception. Surgically removed specimen revealed a small intestinal lipoma.
