Surgical treatment of complicated hepatolithiasis using the ultrasound-guided fiberoptic choledochoscope.
The residual stones of postsurgical intrahepatic calculi have been among the most difficult problems in hepatobiliary surgery. Intraoperative ultrasound can clearly display the morphology of intrahepatic bile ducts and the distribution of calculi as well as the position of the choledochoscope and the calculus extraction instruments. Therefore, intraoperative ultrasound can guide the choledochoscope and its auxiliary equipment for calculus extraction. It is necessary to evaluate the effectiveness and safety of surgeries using an ultrasound-guided fiberoptic choledochoscope for the treatment of complicated hepatolithiasis.
