Experience with the routine use of the pharmacologically aided, double-contrast examination to demonstrate various primary and healing ulcers over a six month period is assessed. Thirteen linear or rod-shaped ulcerations were diagnosed. It appears that gastric relaxation and the demonstration of fine mucosal relief are necessary to detect ulcers of linear or rod form.
The value of the routine pharmacologically-aided double-contrast examination of the upper gastrointestinal tract in demonstrating superficial gastric erosions was assessed. Ten cases of erosive gastritis were diagnosed during a six-month period. It appears that erosive gastritis is more common than generally believed. Diagnosis requires relaxation of the stomach and demonstration of fine mucosal relief by the double-contrast technique.
