Identification of hemorrhagic site of the intestine by RI-angiography.

A 36-year-old man was transferred to our department because of massive malena followed by shock. Gastroduodenal endoscopy revealed no bleeding source in the stomach or the duodenum. RI-angiogram performed immediately after admission revealed a bleeding area at the jejunum and laparotomy was done. The bleeding lesion was detected by exploratory jejunotomy and a jejunectomy was successfully performed over 15 cm, including the lesion. RI-angiogram is useful as selective angiography in the diagnosis of intestinal bleeding and is less invasive.
