[A rare cause of iron deficiency anemia: recurrent hemorrhage from a carcinoid of the jejunum--diagnosis and therapy with enteroscopy].

We report a 66-year-old patient with previously diagnosed iron deficiency anemia. He complained of fatigue, but had no further symptoms. Hemoglobin was 9.1 g/dl. Test for occult blood in stool was positive, but gastroduodenoscopy and colonoscopy revealed no bleeding source. The man was referred to our department for push-type enteroscopy. By enteroscopy we diagnosed a pedunculated, large polyp in the upper jejunum. The polyp seemed to be submucosal, but had some ulcerations on its surface as the probable bleeding source. In the lower parts of the small intestine no further polyps were detected. After endoscopic doppler examination we injected adrenaline into the base of the polyp to prevent bleeding and the polyp was removed by snare without complications. The polyp was diagnosed to be a carcinoid and was removed in sano.
