The double contrast barium meals and endoscopic examinations of 246 patients with 264 benign gastric ulcers were reviewed with regard to the location of these ulcers. Seventy-four per cent of ulcers were found in the antral portion of the stomach within 7 cm of the pyloric canal. A similar study in the United Kingdom revealed that the majority of ulcers were in the upper body of the stomach. Since true gastric ulcers almost always arise in a pyloric type of mucosa, or in the zone of transition from pyloric to body type mucosa, perhaps this junction zone lies higher in a United Kingdom population than in North Americans. Possibly the higher transition zone and the documented higher frequency of gastric malignancy in the United Kingdom are related.
