X线引导经胆道镜U100双频激光治疗术后胆管残留结石

Treatment of biliary calculi with the double-pulse U100 laser through electronic choledochoscope under X-ray guidance

目的介绍X线引导经胆道镜U100双频激光治疗术后胆管残留结石技术,评估其应用价值。方法将术后胆管残留结石患者随机分为3组,每组40例。治疗方法:Ⅰ组胆道镜检+网篮取石术;Ⅱ组胆道镜检+U100双频激光碎石+网篮取石术;Ⅲ组X线引导胆道镜检+U100双频激光碎石+网篮取石术。结果Ⅰ组治愈率(指初次治愈率)为50.00%,平均手术耗时(75±30)min,并发症发生率为5.00%。Ⅱ组治愈率为75.50%,耗时(81±29)min,并发症发生率为0.00%。Ⅲ组治愈率为95.00%,,耗时(62±19)min,并发症发生率为0.00%。结论X线引导胆道镜U100双频激光碎石能有效治疗肝内外胆管残留结石,尤其在难治性结石的治疗上存在优势,可减少操作时间,提高胆管残留结石清除率,并发症少,可在临床推广应用。

[Objective] To introduce and evaluate the technique cholangioscopic double-pulse U100 laser under X-ray guidance for biliary duct residual stone ＇after operation. [ Methods ] The 120 cases with biliary duct residual stone after operation were divided into 3 groups randomly （ Ⅰ -Ⅲ group,n=40）. The patients in the first group were treated by cholangioscopic basket calculus removed technique, at the same time the second group by the technique cholangioscopic double-pulse UIO0 laser ,the third group by the cholangioscopic technique with double-pulse U100 laser under X-ray guide. [Results] The first cure rate was 50.00% in the first group, 75.50% in the second group, 95.00% in the third group. The average operation time consuming was （75 ± 30） rain, （81± 29） min, （62± 19） min differently. The complication incidence was 5.00%, 0.00%, 0.00% differently. [ Conclusion] The treatment method of biliaty Calculi （especial refractoriness stone） with the Double-Pulse U100 Laser through electronic choledochoscope under X-ray guide is effective and safe, which can decrease operation tittle and increase cure rate of biliary calculi.
