More than 100 years ago (1829) Cruveilhier4 made the observation that chronic gastric ulcers are usually situated at the lesser curvature. This has been confirmed by many writers, but no valid explanation for this peculiar localization has come forward.
There is strong evidence (Bolton2 and Konjetzny9) that chronic gastric ulcers arise from acute ulcers. Thus two problems present themselves: first, the cause of acute ulcers, and, second, the factors which lead to the persistence or nonhealing of ulcers.
