[Combined bronchopulmonary and gastroduodenal diseases]

Combined changes in the mucous membrane of the esophagus, stomach, and duodenum were studied in 110 patients with acute and chronic diseases of the lungs on the basis of the endoscopic method, taking into account the immunological mechanisms and analysis of data of 1,000 autopsy records. Combined changes in the lungs and organs of the upper digestive tract were found in 90.9% of patients, erosive-ulcerative lesions of the mucous membrane in 39.3%, and gastrointestinal hemorrhages in 1.7% of patients. Ulcers of the cardiac part of the stomach were encountered most frequently in this category of patients, but hemorrhage occurred mostly as a complication of ulcers of the body of the stomach.
