Obscure bleeding in the gastrointestinal tract originating in the small intestine.
In the past 12 years, we operated upon 49 patients with bleeding lesions of the small intestine. After endoscopic examination and barium studies of the upper and lower gastrointestinal tract excluded esophagogastroduodenal and lesions of the colon and rectum, preoperative examinations consisted of technetium-99m pertechnetate scan, technetium-99m labeled erythrocyte scan, barium studies of the small intestine and selective visceral angiogram. In one patient, diagnostic laparotomy had to be done before any procedure because of severe bleeding and angiosarcoma of the ileum. The results of gross examination at operation revealed bleeding lesions in 40 patients. Special intraoperative localization procedures consisting of methylene blue injection through superselectively prepositioned angiographic catheter was done on eight patients, and intraoperative enteroscopy was done on 17 patients. These two procedures were complementary, having their own indications and limitations. Our regimen of preoperative and intraoperative localization procedures was effective in the management of bleeding small intestinal lesions.
