Abstract：
In recent years, both international and domestic societies have published several guidelines on diagnosis and management of intra-abdominal infection. Due to the different evidence and the different methods adopted in the actual formulation of the guidelines, the recommendations of each version of the guidelines are different. Three international guidelines with great impacts were reviewed, including Diagnosis and management of complicated intra-abdominal infection: guidelines by the Surgical Infection Society and the Infectious Diseases Society of America published in 2010, The Surgical Infection Society revised guidelines on the management of intra-abdominal infection published in 2017, and The management of intra-abdominal infections from a global perspective by the World Society of Emergent Surgery. The above guidelines were used to compare with the Chinese guidelines on the diagnosis and management of intra-abdominal infection (2019) which was published in early 2020. Recommendations on the disease severity classification, source control, and antimicrobial therapy are further explained in order to provide guidelines for clinicians.
近年来，国内外学会先后发布了若干版本的腹腔感染诊治指南。由于各版指南依据的循证医学证据不同，指南实际制定采取的方法亦不同，造成了各版指南中推荐意见的差异。本文仅选取2010年由美国感染病学会（IDSA）与北美外科感染学会（SIS）联合发布的《复杂腹腔感染诊治指南》、由SIS牵头更新形成的2017版《腹腔感染诊治指南》和2017年由世界急诊外科学会发布的《基于全球视野的IAI诊治指南》这三部国际影响力较大的指南，以及2020年初我国发表的首部《中国腹腔感染诊治指南（2019版）》，旨在就各版指南在疾病严重度分级、感染源控制以及抗感染治疗等方面的推荐意见进行解读，希望能够为临床上更好地应用指南提供参考。.
