Features of the diagnostics and treatment of a rare source of small bowel bleeding — venous malformations of the small bowel with Blue rubber bleb nevus syndrome (Bean’s syndrome)

The aim of the study is to demonstrate the possibilities of enteroscopy in diagnostics of rare source of small bowel bleeding in patient with blue rubber blue nevus syndrome. A 31-years old patient with severe anemia from the early age applied to our Hospital to diagnose the source of gastrointestinal bleeding. Previously performed EGD and colonoscopy didn’t reveal any sources of bleeding. Scintigraphy detected the signs of ongoing intestinal bleeding. Endoscopic methods (videocapsule and balloon-assisted enteroscopy) revealed multiple venous malformations of small bowel, as the source of gastrointestinal bleeding of «unknown source». The patient was performed surgery — resection of segments of small bowel with malformations. The diagnosis was verified morphologically. Postoperative period was without complications. For the first time in several years the patient had a fully restored level of hemoglobin.
