Glucagon-induced small intestinal hypotonia demonstrating bleeding lymphoma.
While a patient was being evaluated for melena, a glucagon-induced hypotonic examination of the small intestine demonstrated a small ulcerated mass in the jejunum. The tubeless hypotonic examination was performed after multiple gastrointestinal series, small intestinal series, barium enemas, and visceral arteriography--including celiac and superior mesenteric arteriograms--failed to identify a bleeding site. Surgical exploration revealed three ulcerated lymphomatous lesions in the jejunum. The lack of side effects, rapidity of onset, and shortness of duration of intravenous glucagon suggest that this type of hypotonic examination of the small intestine may prove useful as an adjunct to the small intestinal series.
