肝移植术后肝内胆管狭窄的球囊扩张治疗

目的：成球囊扩张肝移植术后肝内胆管狭窄的疗效进行初步的探索和总结。方法：100例接受肝移植的病人，对其中16例存在肝内胆管狭窄者均采用经T管球囊扩张治疗，并对治疗前后肝功能检查，T管造影检查，T管引流量的检查，临床表现进行对比观察。结果：16例病人中14例球囊扩张成功，2例扩张无交,未发生与球囊扩张相关的并发症；随访期间6例保持通畅，4例分别于扩张1，2，4个月后出现再狭窄，均再次行球囊扩张治疗，5例病人死于肝动脉狭窄引起的肝功能衰竭。结论：球囊扩张治疗对于肝移植后肝内胆管狭窄是一种有效而且相对安全治疗方法，对于再狭窄者，再次进行球囊扩张仍可取得很好的效果。

Balloon dilatation of intrahepatic biliary strictures in liver transplantation

Objective To evaluate the efficacy of balloon dilatation in the treatment of intrahepatic biliary strictures in patients with liver transplantation. Methods Of the 100 patients with liver transplantation, 16 patients had intrahepatic biliary strictures and received balloon dilatation treatment. Results Initial technical balloon dilatation was successful in 14 cases but failed in 2 cases. There were no procedure-related complications. 4 restenosis occurred and they were treated with repeated balloon dilatation treatment. Conclusion Balloon dilatation represented an effective and relatively safe treatment for biliary stricture in liver transplant recipients. For restenosis, balloon dilatation was also an effective treatment.
