Sleeve gastrectomy was first performed as a component of biliopancreatic diversion with duodenal switch (BPD-DS) and subsequently used as the initial stage of a two-staged approach for super-morbidly obese patients. It is now a stand-alone bariatric procedure due to its demonstrated effectiveness in achieving weight loss and resolution of obesity comorbid conditions.

 

It is a restrictive procedure which involves the resection of two-thirds of the stomach to provide increased satiety and decreased appetite. Through restriction in the stomach size, the intragastric volume is less able to accommodate a large volume of food leading to decreased food consumption.
The resection of the gastric fundus determines a decrease in levels of ghrelin, the “hunger hormone” that regulates appetite. This factor, together with the reduced volume of the stomach, can provide a decrease in the caloric assumption, thus leading to weight loss.

 

This procedure is particularly indicated in diabetics and super obese patients and its outcomes are comparable to gastric bypass at 3 year follow-up.
Sleeve Gastrectomy is the most performed procedure in our center, also as revision surgery after failed Gastric Banding.
