Abstract:
Objective To explore the feasibility and value of ultrasonography during choledocholithotomy with fibroptic choledochoscope. Methods Fifty-one cases of intrahepatic bile duct stones after cholecystomsy as diagnosed by pre-operative examination with ultrasound, CT, magnetic resonance imaging from Jan. 2007 to Dec. 2008, underwent conventional lithotomy through fibroptic choledochoscope first, and then high-frequency probing with ultrasonography was done directly over the surface of liver to detect the existence of any residual stone in the bile duct. The position of residual stone, if there was any, was then accurately determined and removed through fibroptic choledochoscope under the guidance of ultrasonography. Results Of 51 patients who had undergone lithotomy through fibroptic choledochoscope, 12 patients were found to have residual stones in their bile ducts after operation. The rate of complete calculus removal was 76.5%, and of residual stones was 23.5%. Of the 12 patients with residual stones, 7 patients were found to have residual stones in their intrahepatic bile ducts complicated with deformed bile duct, 5 patients were found to have residual stones in their intrahepatic bile ducts complicated with stricture of bile duct. All residual stones in intrahepatic bile ducts of 12 patients were accurately located and then completely removed under the guidance of operative ultrasonography through fibroptic choedochoscope without any complications. Conclusions The difficulties of residual stones after lithotomy may be overcome by localization with ultrasonography and removal under the guidance of atfrasonography, so the technique is of practical value in clinical application.
