Intususcepción ileocólica en un adulto causado por divertículo de Meckel invertido

Abstract

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. It is found in 2.00% of the population and is more frequent in children. Invagination is an unusual complication that can cause secondary intestinal intussusception. This event is extremely rare and only a few cases have been reported. We present the case of a 19-year-old male who presented with chronic abdominal pain and weight loss of 23 Kg 6 months prior to hospital admittance. The last episode manifested as intense abdominal pain, nausea, vomiting, and diarrhea with a 6-hour progression. Imaging studies established the diagnosis of bowel obstruction and ileocolic intussusception. Laparotomy with ileocolic resection was performed without reducing the intussusception. The histopathologic study reported inverted Meckel's diverticulum at the base of the ileocolic intussusception. Intestinal intussusception in adults, secondary to inverted Meckel's diverticulum is rare and should be considered in the differential diagnosis of patients presenting with abdominal pain and bowel obstruction.
