Long-term Weight and Metabolic Effects of Laparoscopic Sleeve Gastrectomy Calibrated with a 50-Fr Bougie

Background Most surgeons calibrate the sleeve with 32-French (Fr) to 40-Fr bougies hypothesizing that smaller bougies are associated with greater weight loss and long-term lower weight regain. The purpose of this study was to assess the weight loss results and resolution of comorbidities 5 years after laparoscopic sleeve gastrectomy (LSG).
