[Pathologic changes of major duodenal papilla in biliopancreatic diseases].

The condition of the major duodenal papilla and the periampullary region was studied in 1,113 patients with diseases of the biliary tract and pancreas. In 88.6% of cases complex examination revealed various pathological changes which were considered to be important etiological factors of the development of the diseases. These changes were found to be particularly significant in patients with the postcholecystectomy syndrome. The authors present the modern methods for correction of pathology of the major duodenal papilla, among which endoscopic interventions are most valuable.
