Introduction: Up to 10% of bile duct stones are deemed 'difficult' because they cannot be extracted using standard endoscopic techniques. In these situations, cholangioscopy allows for stone fragmentation under direct visual control.

Intrahepatic biliary stone disease is a difficult condition to treat, due to anatomical complexity of biliary tract, association with colestasis, and high recurrence rates, with potential short- and long-term complications, such as cholangitis and secondary biliary cirrhosis. Removal of biliary stones via intraductal access can be achieved endoscopically or percutaneously, with preference for cholangioscopy-guided laser lithotripsy in complex cases. The surgical approach, despite its prolonged results, is a more invasive and risky procedure.

Methods: Eighty patients with intractable hepatolithiasis who received treatment in the Second Hospital Affiliated to Zhejiang University School of Medicine from December 2020 to December 2022 were grouped according to the surgical methods. Forty-two patients who received hepatectomy were divided into the control group, 38 patients who received new fiber-optic choledochoscope-guided PTCSL combined with dual-frequency laser lithotripsy were divided into the observation group, and the treatment results of the two groups were compared.

: While studies have demonstrated the efficacy of cholangioscopy-guided Holmium-Yttrium aluminum garnet (Ho:YAG) laser lithotripsy for the treatment of refractory bile duct stones, data regarding the safety of the operating parameters for laser lithotripsy are lacking. The aim of this study was to determine safe, yet effective, energy settings for Ho:YAG laser in the ex-vivo model. : This ex vivo experimental study utilized the Ho:YAG laser on porcine bile duct epithelium and human gallstones.
