title: Site of duodenal ulcer and its influence on the mode of presentation and prognosis.
abstract: Two hundred and forty-five endoscopically proven or surgically treated duodenal ulcers were retrospectively evaluated to see if the site of ulcer has any influence on the clinical presentation, and healing and relapse rates. Anterior wall ulcer was present in 42%, posterior wall in 33%, lesser curve side of the cap in 12% and greater curve side in 13% cases. Ulcer site showed no correlation to age, sex, duration of illness, analgesic intake or smoking habits. Bleeding (116 cases) and perforation (15 cases) were the major complications encountered; of these perforation was invariably found on the anterior wall, while bleeding was more frequent in ulcers present on the lesser curve side of the cap. Better healing and high relapse rates were seen in ulcers situated on the greater curve, and low healing and relapse rates in lesser curve duodenal ulcers.
