ASMBS literature review & clinical guidelines on prevention, diagnosis, and treatment of Wernicke's encephalopathy and Wernicke-Korsakoff syndrome.

The American Society for Metabolic and Bariatric Surgery (ASMBS) Wernicke's Task Force issues the following guidelines to enhance the quality of care in patients undergoing bariatric surgery and for other populations at risk of thiamine deficiency and Wernicke's encephalopathy (WE). This paper examines the current literature regarding the prevention, diagnosis, and treatment of WE. These guidelines intend to provide an objective summary of current peer-reviewed literature and provide clinical practice recommendations based on this literature and expert opinions. The goal is to enhance awareness and reduce the incidence of WE and the Wernicke-Korsakoff syndrome (WKS). This statement is not intended to establish a local, regional, or national standard of care and may be revised in the future as additional evidence becomes available.
