总结运用腹腔镜、胆管镜、十二指肠镜（三镜）联合手术的治疗经验。

回顾性分析1992年3月至2009年3月我院运用三镜术中联合手术对胆总管扩张疑有病变的1594例患者进行治疗的经验及效果。

即时缝合的905例中857例及T管引流的689例中633例治疗获得成功。中转开腹14例，胆漏59例，术后残余结石内镜未能取净11例，其他15例，死亡5例。

只要选择合适的病例，三镜术中联合手术是可行、有效和安全的。

To summarize the experience of the combination operation of laparoscopy, choledochoscopy and duodenoscopy for treatment of extrahepatic bile duct stones and stenosis of terminal choledoch during the course of therapeutic laparoscopy (LCDST).

The clinical data of 1594 patients undergoing LCDST were analyzed retrospectively from March 1992 to March 2009 in our hospital.

The procedure was successful in 857 in 905 cases with primary suture of duct incision and 633 in 689 cases with T tube drainage. Fourteen cases were shifted to open common bile duct exploration. Bile leakage occurred in 59 cases. Residual stones were not removed by endoscopy in 11cases. Fifteen cases were other complications. Five cases died postoperatively.

If patients are suitable, LCDST is a feasible, safe and effective method for skilled endoscopists.
