The leadership of the World Surgical Infection Society (WSIS), in response to a gap in the surgical and infectious diseases literature, formed a working group specifically to address surgical and technical aspects of obtaining source control in
intra-abdominal infections. The guideline will provide recommendations for good practice that are based on the best available evidence of clinical and cost effectiveness from a global perspective.


This guideline is intended to be complementary to the diagnosis and antibiotic-focused treatment guidelines currently in existence. The guidelines will refer to those previously published by the World Society of Emergency Surgery (WSES), ‘The management of intra-abdominal infections from a global perspective: 2017 WSES guidelines for management of intra-abdominal infections [1],’ the Surgical Infection Society (SIS), ‘The Surgical Infection Society Revised Guidelines on the Management of
Intra-Abdominal Infection [2],’ and the SIS and the Infectious Diseases Society of America (IDSA), ‘Diagnosis and Management
of Complicated Intra-abdominal Infection in Adults and Children: Guidelines by the Surgical Infection Society and the Infectious Diseases Society of America.


WSIS clinical guidelines support the role of healthcare professionals in providing care in partnership with patients, taking account of their individual needs and preferences, and ensuring that patients (and their careers and families, where appropriate) can make informed decisions about their care and treatment.
