快速球囊扩张导管治疗肝内胆管狭窄56例临床分析

Rapid balloon dilatation catheter in treatment of intrahepatic bile duct stenosis in 56 cases

目的探讨肝内胆管狭窄的有效治疗方法。方法 56例肝内胆管狭窄患者,应用快速胆管球囊扩张导管和压力泵装置,在胆管镜直视或X线监视下,于狭窄胆管置入胆管球囊,并以6-8kPa压力持续扩张5min,观察其治疗效果。结果本组56例79处胆管狭窄,经1次扩张治疗成功72处（91.1%）,7处术后经1-4次再扩张治疗成功,无胆管出血发生;48例术后随访1a,3例发生胆管再狭窄,复发率6.3%。结论应用快速胆管球囊扩张导管和压力泵装置治疗肝内胆管狭窄疗效确切,操作简便、安全。

Objective To explore the treatment of intrahepatic bile duct stenosis. Methods Fifty-six cases of intrahepatic bile duct stenosis were placed biliary balloon by using rapid biliary balloon dilatation catheter and pressure pump under the monitor of choledochoscope or postoperative X-ray.The balloon was continuously dilated at the pressure of 6to 8kPa for 5minutes to observe the therapeutic effect.Results In 56patients（79sites of biliary stenosis）,72 sites of stenosis were once successfully dilated（91.1%）and the other 7sites were successfully treated after twice to 5times dilatation.No biliary duct bleeding occurred.Forty-eight patients were followed up for 1year,in which re-stenosis occurred in 3patients（6.3%）.Conclusion Rapid biliary balloon dilatation catheter and pressure pump system is simple,safe and effective for intrahepatic bile duct stenosis.
