【摘要】 目的　应用等离子体冲击波碎石治疗术后胆管残余嵌顿结石。方法　通过胆道镜引入定向微爆破石仪 (PSW G)探头治疗 44例常规胆道镜难以取出的胆道术后残余结石共 10 1块。结果　碎石成功率为 99% (10 0 / 10 1) ,击碎一块结石所需发放冲击波 2～ 5 0 0次 ,平均 6 0次 ,平均每例病人作胆道镜 2 8次 ,无严重不良反应。结论　等离子体冲击波碎石是一种较理想的配合胆道镜碎石的方法 ,值得推广更多还原

【Abstract】 Objective Using plasma shock wave lithotrpsy to treat postoperative residual stones impacted in biliary duct. Methods Altogether 101 residual impacted stones which failed in a basket extraction were broken by plasma shock wave lithotripsy via a choledochoscope and then removed in 44 postoperative patients after biliary operation. Results The success rate was 99%(1/101) without severe complication. Conclusions Plasma shock wave lithotrpsy combined with choledochoscopy is effective in fragmentating and then extracting impacted residual biliary stones.更多还原
