[Intraoperative cholangioscopy].

Intraoperative fibrocholangioscopy (FCS) was used in 446 patients with cholelithic disease and acute cholecystitis. 399 (89.5%) of the patients were hospitalized urgently. The use of FCS in patients with choledocholithiasis, obturative jaundice, cholangitis and pancreatitis is analysed. The safety and diagnostic accuracy of the method are proved. The use of FCS has provided significant improvement of the immediate and long-term results of the biliary tract surgery.
