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

  • 摘要: 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。

     

  • 表  1  推荐意见的证据等级和推荐强度等级

    级别 详细说明
    证据质量
      高(A) 进一步研究不可能改变对该疗效评估结果的可信度
      中(B) 进一步研究有可能影响该疗效评估结果的可信度, 且可能改变该评估结果
      低或非常低(C) 进一步研究很有可能影响该疗效评估结果的可信度, 且很可能改变该评估结果
    推荐强度
      强(1) 明确显示干预措施利大于弊或者弊大于利
