[Meckel's diverticulum duplication revealed by acute operation of ileus: a case report].

A 29-year-old man was admitted with abdominal pain. Peritonitis symptoms appeared on the day after of hospitalization and emeregency surgery was performed. A Meckel diverticulum adhered to the mesenterium of the sigmoid colon which was strangulated for a length of 30cm. Additionally, a second Meckel diverticulum was present on the oral side of the first one. The length of these were 3cm and 5cm, and the longer one caused the strangulation. The letter diverticulum contained a crab shell about 2cm in size, which was considered to be the cause of adhesion. Our search of the literature revealed only one report of two Meckel diverticula. This type of our case is extremely rare.
