In 2012, an expert panel composed of presidents of each of the societies, the European Chapter of the International Federation for the Surgery of Obesity (IFSO-EC), and of the European Association for the Study of Obesity (EASO), as well as of the chair of EASO Obesity Management Task Force (EASO OMTF) and other key representatives from IFSO-EC and EASO, devoted the joint Medico-Surgical Workshop of both institutions to the topic of metabolic surgery in advance of the 2013 European Congress on Obesity held in Liverpool. This meeting was prompted by the extraordinary advancement made in the field of metabolic and bariatric surgery during the past decade. It was agreed to revise and update the 2008 Interdisciplinary European Guidelines on Surgery of Severe Obesity produced by focusing in particular on the evidence gathered in relation to the effects on diabetes and the changes in the recommendations of patient eligibility criteria. The expert panel allowed the coverage of key disciplines in the comprehensive management of obesity and obesity-associated diseases, aimed specifically at updating the clinical guidelines to reflect current knowledge, expertise and evidence-based data on metabolic and bariatric surgery.

Conflict of interest

The authors have no conflict of interest.


The consensus material in this document is a clinical guideline. It is therefore intended to promote and guide good clinical practice. It should not be construed as a substitute for or as taking precedence over the duty of a clinician to conscientiously apply his/her knowledge and clinical skill to the best interests of a given patient. [235, 236].

It may thus be fully correct to offer or agree treatment out with this guidance. Clinicians may wish to document that they appraised patients clearly when proposing such treatment.

In applying this guidance, clinicians are advised in each case to consider the strength of evidence for any given part of it.

IFSO-EC and EASO are committed to promoting reliance on operationalized and controlled data.
