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).

Methods: A prospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy calibrated with a 50-Fr bougie between October 2007 and February 2010 was performed.

Effect of preoperative eating patterns and preoperative weight loss on the short- and mid-term weight loss results of sleeve gastrectomy.

Introduction: Weight loss depends directly on the adhesion to the postoperative diet in patients undergoing a sleeve gastrectomy. The aim of this study is to evaluate the effect of different preoperative feeding patterns and the adhesion to a preoperative diet on short and mid- term postoperative weight loss.

Material And Methods: A prospective study of all morbidly obese patients undergoing a laparoscopic sleeve gastrectomy as a bariatric procedure between 2008 and 2012 was performed.

[Pre and postoperative adherence to Mediterranean-like diet and its effect on weight loss and cardiovascular risk factors after sleeve gastrectomy].

Purpose: Even in the Mediterranean countries, the adherence to the Mediterranean diet is every day smaller. The aim of this study was to evaluate the adherence to Mediterranean diet of morbidly obese patients before and after undergoing a sleeve gastrectomy.

Materials And Methods: A prospective observational study of all the patients undergoing Laparoscopic Sleeve Gastrectomy (LSG) as bariatric technique between October 2010 and May 2012 was performed.
