Studies on factors affecting healing of gastric ulcer. A prospective, cooperative study in Japan

Abstract

To assess factors influencing the healing of gastric ulcer, a prospective and cooperative study was carried out in Osaka, Japan. Four hundred nineteen patients with single gastric ulcer were followed from May, 1971 to June, 1973. These patients were divided into two groups, "healing" and "delayed healing", on the basis of the criteria by the distribution analysis. By the multivariate analysis of 11 factors picked up, site, size of the ulcer and age were related to healing of gastric ulcer with the larger weight. These results suggest that ulcers of smaller lesions, ulcers of the gastric body, ulcers of the anterior wall or younger patients show faster healing in general.
