Bariatric surgery is a medical specialty dedicated to the treatment of obesity and its comorbidities through surgical procedures. We present a detailed collection on the history and evolution of laparoscopic sleeve gastrectomy over the course of 20 years. The gastric sleeve induces weight loss by several mechanisms. It significantly reduces gastric chamber size and decreases the secretion of the hormone called ghrelin, thus promoting quicker satiety and decreasing appetite.

Karamankos S.N. found a greater percentage of excess-weight loss with gastric sleeve than with bypass in a 1-year follow-up (69,7% ± 14,6% versus 60,5% ± 10,7%). A 2011 meta-analysis by Padwal R. et al. concluded that there is a greater decrease in body mass index in patients undergoing sleeve gastrectomy than with gastric bypass, -10,1 kg/m2 and -9 kg/m2, respectively.
