Objective To investigate the effect of improved biliary tract wash fluid on the complications following biliary endoscopic micro-blasting lithotripsy. Methods From Oct. 2008 to Feb. 2012, 45 cases of residual refractory biliary passage stone were divided into control group (group A given normal saline in 20 cases) and experimental group (group B given the improved biliary tract wash fluid in 25 cases). Depletion achievement ratio of stone, colony counts in bile, abdominal pain during operation and postoperative abdominal pain, fever, diarrhea were observed in two groups. Results The rate of depletion in two groups was 100%. The bile colony counts in the experimental group were significantly less than in the control group(P<0. 05). The incidence rate of intraoperative abdominal pain, and postoperative fever and abdominal pain was significantly lower in the experimental group than in the control group(P<0. 05). Conclusion The improved biliary tract wash fluid can make the rinse liquid to become an effective adjunct to fiber biliary endoscopic micro-blasting lithotripsy, can reduce the colony counts in the bile and the occurrence of intraoperative and postoperative complications.%目的 探讨改良胆道冲洗液对纤维胆道镜下微爆破碎石并发症的影响.方法 2008年10月至2012年2月间45例难取性胆道残余结石行微爆破碎石取石术患者,分为两组,对照组(A组)20例,胆道冲洗液使用生理盐水,实验组(B组)25例,胆道冲洗液使用改良胆道冲洗液,观察两组结石取尽率,胆汁菌落计数,术中腹痛,术后腹痛、发热、腹泻等并发症的发生率.结果 两组结石取尽率均为100％,实验组取石后胆汁中菌落计数明显低于对照组(P＜0.05),术中腹痛发生率及术后发热、腹痛的发生率明显低于对照组(P＜0.05).结论 改良胆道冲洗液可成为纤维胆道镜下微爆破碎石取石的一种有效辅助手段,可减少胆汁中的菌落计数,减少取石术中、术后并发症的发生.
