[Comparison of push-type endoscopy and barium transit study of the small intestine in digestive bleeding and unexplained iron-deficiency anemia].

Abstract

Push-type enteroscopy was more effective than small bowel follow-through to detect the origin of obscure gastrointestinal bleeding. Push-type enteroscopy revealed a cause of bleeding in 35% of patients, located in the small bowel in only 15% of the patients.
