abstract: The results of treatment of 13,246 patients with acute surgical disease of the abdominal organs have been analysed. In 48 patients, bleeding from a stress ulcer occurred. The symptoms of bleeding were studied. The variants of the clinical course of postoperative acute erosion and ulcer, such as the lightning-like, double-phase, single-phase ones, have been distinguished. Their predictive value is shown. In 89.6% of the patients, a postoperative stress ulcer developed in diseases of the hepatopancreatobiliary zone organs.
