目的 探讨经内镜十二指肠乳头括约肌切开术后胆总管结石复发的危险因素.方法 采用回顾性方法对320例因胆管结石行经内镜十二指肠乳头括约肌切开术患者的临床资料进行分析.结果 298例患者经内镜十二指肠乳头括约肌切开术后获得随访.有36例患者发生术后胆总管结石复发,发生率为12.08%.多因素Logistic回归分析显示:年龄≥65岁、高脂血症、壶腹周围憩室、胆总管直径≥15 mm、胆道积气、胆总管结石数量较多是经内镜十二指肠乳头括约肌切开术后胆总管结石复发的危险因素.结论 经内镜十二指肠乳头括约肌切开术后胆总管结石复发的危险因素较多,针对各项危险因素应引起重视,降低胆总管结石术后复发率.%Objective To explore the risk factors for the recurrent choledocholithiasis after endoscopic sphincterotomy.Methods The clinical data of 320 consecutive patients who underwent EST for bile duct stones were analyzed retrospectively.Results Follow up were definited in 298 patients after EST,there were 36 patients postoperative recurrence of common bile duct calculi with rate of 12.08%.Logistic regression analysis showed that ≥65 year old,hyperlipidemia,periampullary diverticula,bile duct diameter≥15 mm,biliary pneumatosis,bravery manager number were the risk factors of recurrent choledocholithiasis.Conclusion Recurrent choledocholithiasis in endoscopic sphincterotomy patients are associated with many factors,and the intervention measures should be taken to reduce the incidence of recurrent choledocholithiasis.
