Results of surgical treatment of duodenal ulcer, complicated by hemorrhage, in patients, who were exposed to the small doses of radiation influence, are unsatisfactory. General, local immunity were studied up, pH-metry of gastroduodenal zone was conducted, activity of Helicobacter pylori (HP) urease was determined in patients with duodenal ulcer, complicated by hemorrhage, who have been exposed for a long time to the small doses of radiation influence and who were not. In patients, who have been exposed to radiation influence, reduction of secretory immunoglobulin A (sIgA) in duodenal mucus was revealed. Conduction of the local immunity changes correction, performing organpreserving surgical intervention and using immunocorrecting therapy after the operation, are recommended for improvement of the surgical treatment results.
