摘要: 原发性胆汁性胆管炎(PBC)是一种伴有胆汁淤积的慢性自身免疫性肝脏疾病,其组织学特征为非化脓性胆管炎。本文简述了传统的PBC病理分期系统如Rubin分期、Scheuer分期以及Ludwig分期和最新的Nakanuma分期各自的优点和局限性,其中Nakanuma分期细化了组织学分级分期标准,减少因采样误差而漏诊的机会,从而为临床提供更充分的诊断及预后信息。新旧分期系统结合应用更有利于指导PBC的诊治和相关研究。Abstract: Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease accompanied by cholestasis, with the histological feature of non-purulent cholangitis. This article briefly describes the advantages and limitations of the traditional pathological staging systems such as Rubin stage, Scheuer stage, and Ludwig stage and the latest Nakanuma stage. Among them, Nakanuma stage refines the histological grading and staging standards to reduce the chance of missed diagnosis due to sampling errors, thus providing more adequate diagnostic and prognostic information for the clinic. A combination of new and traditional staging systems can provide guidance to the diagnosis, treatment, and research of PBC.
