[Guidelines on the diagnosis and management of primary sclerosing cholangitis (2021)].

In 2015, the first Chinese consensus on the diagnosis and management of primary sclerosing cholangitis was issued. In the past years, more data have emerged from the literature. Herein, the Autoimmune Liver Disease Group of the Chinese Society of Hepatology organized an expert group to review the evidence and updated the recommendations to formulate the guidelines. There are 21 recommendations on PSC clinical practice. To facilitate the differentiation between PSC and IgG4-related sclerosing cholangitis, 10 recommendations on IgG4-SC are also attached. These guidelines aim to provide a working reference for the management of PSC and IgG4-SC.2015年我国第一个原发性硬化性胆管炎（PSC）的专家共识颁布。近年来PSC的临床研究提供了PSC新的研究数据和资料。为此，中华医学会肝病学分会自身免疫性肝病学组组织专家组对近年来的文献证据进行了评估，制定了本指南。本指南共有PSC推荐意见21条。为了利于鉴别PSC和IgG4相关硬化性胆管炎（IgG4-SC），也附有IgG4-SC的10条推荐意见。本指南的目的是为临床PSC和IgG4-SC的诊治提供参考和指导。.
