Laser lithotripsy for postoperative intrahepatic residual stones under choledochoscopy report of 74 cases

目的探讨胆道镜下U-100双频激光碎石术治疗术后残余肝内结石的临床疗效。方法对74例胆道术后肝内胆管残余结石患者接受胆道镜下U-100双频激光碎石治疗患者的临床资料进行回顾性分析。结果63例（85．1％）1次碎石成功，8例（10．8％）碎石2次，3例（4．1％）碎石3次。碎石成功率100％。结论胆道镜下U一100双频激光碎石是治疗术后残余肝内结石的一种安全有效手段。

Objective Explore the clinical effect of U-100 double-frequency laser lithotripsy in postopera- tive residual intrahepatic calculus under eholedochoscopy. Methods Severty-four patients of postoperative in- trahepatic residual stones with U-100 double-frequency laser lithotripsy under eholedochoscopy were analyzed retrospectively. Results Sixty- three （85.1% ） of 74 cases were treated successfully in the first operation, 8 cases （ 10.8% ） obtained satisfactory outcome in the second operation, and 3 cases （4.1%） in the third. All lithotripsies were performed successfully. Conclusions U-100 double-frequency laser lithotripsy in postoper- ative residual intrahepatic calculus under choledochoscopy provides a safe and effective method.
