Common bile duct stones in cholecystectomized patients (chapt. 28) in Biliary lithiasis Basic science, current diagnostic and therapeutic approaches di C. Cordiano e G. Borzellino

Abstract

The incidence of retained or primary stones is approximately 2-5% after LC and 5-15% after common bile duct exploration: in principle, these patients are in need of further intervention. Residual common bile stones are called secondary when they originate in gallbladder and later pass down through the cystic duct into the common bile duct.
