胆道闭锁Kasai术后胆管炎影响了患儿自体肝的生存状况，尤其是Kasai术后1年内反复发生的胆管炎，更易形成难治性胆管炎，严重影响了胆道闭锁Kasai手术的治疗效果。目前Kasai术后胆管炎病因尚不清楚，多数学者认为并非单一因素所致，与胆汁引流量下降、术后类固醇激素使用、肠道菌群移位、自身免疫损伤等因素密切相关。本文综述了胆道闭锁Kasai术后胆管炎发生的相关因素，为将来胆道闭锁的进一步治疗及Kasai术后胆管炎并发症的防治提供参考。“,”Cholangitis of biliary atresia (BA) after Kasai procedure (KP) affects the survival status of native liver in children.
