Objective To inverstigate the effect and safety of refractory intrahepatic and extrahepatic bile duct stones treated by choledochoscope holmium laser combined with electrohydraulic lithotripsy.Methods The cllnical data of 67 cases of postoperative intrahepatic and extrahepatic bile duct stones treated with combined endoscopic holmium laser and electrohydraulic lithotripsy were analysed retrospectively.Results After 1 to 7 times of biliary endoscopic holmium laser electrohydraulic lithotripsy treatment,65 patients had complete removal of all residual stones with the success rate of 97%,and without complications.Conclusions After holmium laser combined with electrohydraulic lithotripsy,the effect of choledochoscopic removal of intrahepatic and extrahepatic bile duct residual stones can be greatly improved It is a safe method for treatment of refractory intra-and extra-hepatic bile duct stones.
