ABSTRACT

Objective To compare the detect abilities of obscure gastrointestinal bleeding by capsule endoscopies and conventional intestinal examinations.Methods To analyze the results of gastrointestinal barium meal examination, arteriography of superior mesenteric artery, push enteroscopy, capsule endoscopy, and enteroscopy during exploratory laparotomy in 67 patients with obscure gastrointestinal bleeding.Results Detectable rates of gastrointestinal barium meal examination, arteriography of superior mesenteric artery, push enteroscopy, capsule endoscopy, and enteroscopy during exploratory laparotomy are 17 6%, 13 4%, 32 0%, 80 6%, and 83 3% respectively, and their diagnostic rates are 13 8%, 13 4%, 32 0%, 67 7%, and 83 3% respectively. Conclusion Capsule endoscopy is superior to conventional methods of intestinal examinations having high detectable and diagnostic rates in obscure gastrointestinal bleeding; it should be the first choice in diagnosing obscure gastrointestinal bleeding.
