BACKGROUNDIleal duplication is a rare congenital abnormality that can present in any portion of the GI tract and it is observed in one out of 25000 deliveries. Most of the adult intestinal duplications are asymptomatic and remain undiagnosed for years until onset of complications. It is rarely associated with volvulus. Ileal duplication can be classified according to the shape as cystic (noted in more than 80%) or tubular. Intestinal duplications may have an acute presentation or chronic complaints. In our case report, the patient presented with pain in abdomen with vomiting and melena. CT scan showed midgut volvulus secondary to malrotation. Intraoperatively, it shows ileal loops adhered to each other close to terminal ileum and hence proceeded with right hemicolectomy. Histopathologically, it was confirmed to be ileal duplication with gastric heterotopia.
