Abstract
IntroductionIleal duplications are encountered infrequently in adults, because symptoms including abdominal pain, intussusception, hemorrhage, and perforation usually present in early childhood. In this report, we present an adult case of ileal duplication that was revealed by double-balloon endoscopy (DBE).Case descriptionA 73-year-old Japanese man presented with anemia and melena. Anal DBE detected the narrow opening of an extra lumen in the ileum about 100 cm proximal to the ileocecal valve. Enteroclysis via DBE showed a 5-cm-long ileal diverticulum-like structure at the mesenteric side of the ileum. No ectopic gastric mucosa was detected by technetium-99m pertechnetate scintigraphy. The final diagnosis was ileal duplication.Discussion and evaluationThis is the first report of tubular ileal duplication diagnosed by using DBE. The small intestinal duplication opening was not detected by using VCE and plane CT in this case, but was found by using DBE.ConclusionsThe present case demonstrates that DBE was useful in the diagnosis of an adult small intestinal duplication that was not visualized by other modalities.

Summary
Enteric duplication is a rare congenital disease It is mainly observed in the small intestine, it can occur anywhere in the gastrointestinal tract. Ileal duplications are encountered infrequently in adults, because symptoms including abdominal pain, intussusception, hemorrhage, and perforation usually present in early childhood (Cheng et al 2014; Furuya et al 2012). We. Case description A 73-year-old Japanese man whose only significant medical history included endoscopic submucosal dissection for early gastric cancer in 2013 and 2014 visited our hospital because of abdominal pain, anemia, and melena in June 2015. Esophagogastroduodenoscopy and colonoscopy revealed no bleeding sources other than the small intestine His symptoms improved without treatment soon after visiting the hospital, he was admitted for further investigation of the cause of anemia and melena in February 2016. We concluded that the abdominal pain, anemia, and melena were caused by the ileal duplication. We will perform surgical excision, including partial resection of the ileum
