内镜治疗胆总管结石术后复发的危险因素分析

The Risk Factors for Recurrence after Endoscopic Sphincterotomy in Treatment of Choledocholithiasis

目的分析内镜治疗胆总管结石术后复发的危险因素。方法回顾分析187例行经内镜乳头括约肌切开术(EST)治疗胆总管结石患者的临床资料。结果 6例(3.21%)出现近期并发症,28例(14.97%)出现远期并发症,其中胆总管结石复发26例(13.90%);体重指数高、胆管炎史、胆总管直径增大及血清胆固醇含量升高是结石复发的危险因素(P<0.05);乳头切口小(约1.0cm)是结石复发的保护因素(P<0.05)。结论体重指数、胆管炎史、胆总管直径、乳头切口大小及血清胆固醇含量与EST术后结石复发相关。

Objective To analyse the risk factors for recurrence after endoscopic sphincterotomy in treatment of choledocholithiasis. Methods Reviewed the clinical data of 187 cases of choledocholithiasis were treated by EST. Results Six cases （3.21%）had short-term complication, and 28cases （ 14.97% ）had long-term complication, 26 cases （ 13.90% ）were recurrence therein. The high BMI, cholangitis history, common bile duct diameter increased and serum cholesterol increased were the risk factors for recurrence of choledocholithiasis （ P 〈 0.05 ）. The small duodenal papilla cut diameter （ about lcm ） was the protective factors for recurrence of choledocholithiasis （P 〈 0.05 ） .Conclusion The BMI, cholangitis history, common bile duct diameter, serum cholesterol and duodenal papilla cut diameter are related to recurrence of choledocholithiasis.
