Endoscopic sleeve gastroplasty: the identification of the key procedural steps through a modified Delphi method

Endoscopic sleeve gastroplasty (ESG) is an innovative, minimally invasive bariatric procedure with an excellent safety and efficacy profile in adults with obesity. The purpose of the procedure is to shorten and tubularize the stomach along its greater curvature. Nevertheless, there are some heterogeneities in the approach to ESG, which will be important to address as the procedure sees increasingly widespread clinical adoption. Here, an expert consensus on standardized ESG techniques is presented.
