The importance of laparotomy in the diagnosis and management of intestinal bleeding of obscure origin.
Thirty-seven patients who had had either a colonoscopy or a selective mesenteric angiogram while being investigated for severe or persistent gastrointestinal bleeding of obscure origin were reviewed. Failure to make a prompt diagnosis was partly responsible for the 16% hospital mortality in the series. Colonoscopy was diagnostic on 6 out of 38 examinations but detected 43% of lesions in the colon. Angiography achieved only 3 diagnoses in 17 examinations. Fourteen patients had an exploratory laparotomy which was diagnostic in 9. We believe that early laparotomy still has an important place in the diagnosis and treatment of intestinal bleeding of obscure origin.
