2、,其中因肝动脉狭窄或栓塞引起的胆漏、胆道狭窄和肝内局限性坏死7例(5例经溶栓及内支架介入治疗后恢复、2例因肝功能衰竭并感染死亡);胆道狭窄8例(6例经再次手术和ERCP及PTCD胆道内、外支撑等介入治疗恢复、2例胆管消融并发胆管炎死亡);胆漏7例(6例经再次手术或超声引导下穿刺置管引流治愈、1例保守治愈);胆道铸型2例(均经再次手术治愈)。结论 供肝的质量和完整的动脉采集及胆道黏膜的保护,精细的动脉和胆管吻合是预防肝移植术后胆道并发症的关键。肝动脉溶栓、ERCP及PTCD胆道内支撑等是治疗胆道并发症的有效手段。 【关键词】 肝脏移植; 胆道并发症

9、ansplantation; Biliary complication 肝脏移植目前已成为治疗终末期肝胆疾病的有效手段。但肝移植术后胆道并发症是导致肝移植失败的主要原因之1,其发生率高达15%34%1。因此,预防和治疗胆道并发症对提高肝移植疗效和改善患者生活质量有重要的临床意义。本文结合我院2002年6月至2006年9月160例肝移植患者临床资料,探讨肝移植术后胆道并发症的防治方法。 1 资料和方法 1.1 1般资料
10、 本组160例,男142例,女18例;其中成人159例,儿童1例;年龄870岁,中位年龄46.5岁。成人均为尸体供肝移植,热缺血时间412 min,冷缺血时间416 h。儿童为亲体肝移植,供肝为受者母亲的左半肝,供肝热缺血时间为0,冷缺血时间为140 min。供受者间ABO血型相符160例。供肝冷灌注和保存用4 肾保存液3000 ml、UW液2000 ml。患者原发病:慢性乙型重症肝炎29例,终末期肝硬化27例,肝硬化合并肝癌81例, 暴发性肝功能衰竭11例,遗传代谢性疾病3例,酒精性肝硬化4例,不能手术切除的巨大肝肿瘤5例。 1.2 手术方式&
11、nbsp; 经典原位肝移植4例,背驮式肝移植156例,所有病例均未作体外静脉转流。修整供肝时继续以4 UW液和生理盐水行肝动脉、门静脉和胆道的灌洗,供肝动脉如有变异,均以80 Prolene线进行整形至理想吻合口径(图1)。病肝切除后,供肝植入重建顺序:肝脏流出道、门静脉、肝动脉和胆道。肝静脉流出道采用腔静脉以40 Prolene线侧侧吻合;门静脉以50 Prolene线端端吻合;肝动脉以70、80 Prolene线端端连续吻合;胆道重建方式:供肝胆管尽量剪至肝门血运丰富处,以40整形线或50/60 PDS线连续缝合。全组行胆管空肠RouxenY吻合术10例;胆管胆管端
