The Sleeve Gastrectomy (LSG), also called a vertical sleeve gastrectomy, involves removing approximately 80% of the stomach and leaving a smaller, tube shaped pouch, resembling a banana.


The stomach is 'mobilised' and around 80% is removed from the outer 'stretchier' side. This results in a small volume and firmer, less distensible stomach. It also removes the part of the stomach that produces ghrelin, the hunger hormone. This means that patients don't feel as hungry and can't eat as much without feeling full. The remaining smaller stomach's sides are closed up using a stapling device.
