[The role of fibrocholedochoscopy in the complex intraoperative diagnosis of diseases of the bile ducts].

The method of fibrocholedochoscopy was used by the authors in 622 patients with diseases of the bile ducts. Bile duct stones were detected in 91.4% of the patients. Scarry alterations of the common bile duct wall and Vater's papilla were found in 21.1%. Cholangitis of various degrees were diagnosed in 98% of the patients. The authors propose to make fibrocholedochoscopy parallel with other modern methods of the intraoperative diagnostics in patients with a pathology of the bile ducts.
