目的：探讨研究腹腔镜联合胆道镜手术治疗肝外胆管结石的临床效果。方法：将46例肝外胆管结石患者随机分为联合组和对照组，联合组采用腹腔镜联合胆道镜进行手术，对照组采取传统的开腹手术，观察两组手术时间、腹腔流量、术中出血量、住院时间、术后排气时间、白蛋白等肝功能状况及术后并发症等。结果：两组术中出血量、术后排气时间、腹腔流量、住院时间等差异有统计学意义(P＞0.05)，治疗后两组肝功能差异不具有统计学意义。联合组手术切口小，未出现胆漏、胆道损伤、胆道出血等并发症。结论：腹腔镜联合胆道镜手术治疗肝外胆管结石对机体创伤小，安全有效，并发症少，值得推广应用。“,”Objective:To explore and study the clinical effect of laparoscopy combined with choledochoscopy in the treatment of extrahepatic bile duct calculi.Methods:46 patients with extrahepatic bile duct calculi were randomly divided into the combined group and the control group.The combined group were treated with laparoscopy combined with choledochoscopy operation.The control group were treated with traditional open operation.The operation time,abdominal cavity flow,intraoperatve blood soss, hospitalization time,postoperative exhaust time,albumin and other liver function status,postoperative complications of two groups were observed.Results:The differences of the intraoperatve blood soss,postoperative exhaust time,abdominal cavity flow, hospitalization time between two groups were statistically significant(P<0.05).The liver functions of two groups after treatment had no significant difference.In the combined group,the operative incision was small,and it had no bile leakage,bile duct injury, biliary tract bleeding and other complications.Conclusion:The laparoscopy combined with choledochoscopy in the treatment of extrahepatic bile duct calculi has small trauma for engine body.It is safe and effective,and has less complications.It is worthy of popularization and application.
