医源性胆管损伤修复后再狭窄原因及治疗

胆管损伤（BDI）是胆囊切除术后常见的严重并发症。BDI首次手术修复后胆道再狭窄的原因是多方面的，影响因素主要包括：BDI的类型、手术修复的时机、手术修复的方法、合并肝动脉损伤和术者经验。BDI首次手术后胆道再狭窄的治疗十分棘手，手术难度大。术前详细的影像学特别是胆道树的直接影像检查评估对手术方案的选择十分重要。具体的治疗措施视病人的全身状况、肝功能及其储备功能、胆管狭窄的部位和有无合并肝内胆管结石、胆汁性肝硬化等因素而定。胆道金属支架植入术只适用于高龄、不能耐受手术或预测生存期不超过2年的病人。狭窄段胆管切除、肝门部胆管空肠Roux-en-Y吻合术是最常用的手术方式，效果良好。对左、右肝管或以上胆管狭窄合并肝内胆管结石或肝叶萎缩，健侧肝无肝硬化、肝功能良好的病人，应行肝切除术。
