Comparison of barium swallow and left gastric angiography in the diagnosis of esophageal varices, with special reference to the management of variceal bleeding

Abstract

Seventy-five patients with portal hypertension and esophageal varices were studied by means of barium swallow and selective left gastric angiography. The relative merits and limitations of these techniques in demonstrating the presence, extent, and severity of the varices are discussed, with reference to the selection of patients for prophylactic transection of the esophagus to prevent bleeding from the varices.
