[Interpretation of acute abdomen in the immunocompromised patients: WSES/SIS-E/WSIS/AAST/GAIS guideline].

World Society of Emergency Surgery (WSES), in conjunction with Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) developed guideline about the management of acute abdomen in immunocompromised patients, which was published in the World Journal of Emergency Surgery (WJES) on August 9, 2021. The guidelines elaborate on the definition, classification, diagnosis and treatment of immunocompromised patients. In addition, based on evidence-based medicine, it provides guidance and suggestion on the management of specific acute abdominal infections in immunocompromised patients, common acute abdominal infections in transplanted patients, patients with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS), as well as perioperative steroid management. An interpretation of the guideline was performed to accomplish a better understanding the current status and recommendations for the management of acute abdominal conditions in immunocompromised patients, and to make forward suggestions on its limitations.
