[Endoscopic retrograde cholangiopancreatography in the diagnosis of diseases of the organs of the hepato-pancreato-duodenal group].

Experience with using endoscopic retrograde pancreatocholangiography (ERPCG) in 278 patients has shown the method to be the most valuable one in preoperative diagnosis of diseases of bile ducts. It facilitates establishing the presence of calculi in bile ducts, diagnosis of stenosis of the major duodenal papilla and cholangitis. ERPCG allows establishing the localization of a tumor process in bile ducts. ERPCG should be performed first of all in patients with jaundice and in cases when other diagnostic methods have failed to make the correct diagnosis.
