Double-balloon enteroscopy for diagnosis of Meckel's diverticulum in a patient with gastrointestinal bleeding.
چکیده
A 27−year−old woman presented with a history of gastrointestinal bleeding. Her medical history was otherwise unremark− able. Esophagogastroduodenoscopy and colonoscopy of the terminal ileum were carried out after an episode of gastroin− testinal bleeding, but the source of the bleeding remained unidentified. Double− balloon endoscopy of the small intestine [1] was then conducted via the anal approach. Examination of the distal ileum disclosed a diverticulum with an ulcera− tion at about 50 cm proximal to the ileo− cecal valve (Figure 1). Radiography showed a diverticulum 6 cm long in the ileum (Figure 2). Biopsy specimens from the diverticulum revealed gastric mucosa (Figure 3). The ulcer was thought to be caused by ectopic gastric mucosa.
