A vertical sleeve gastrectomy, or gastric sleeve, is a procedure that decreases your stomach size by removing approximately 2/3 of the stomach. The remaining stomach is a tubular pouch or “sleeve” that resembles a banana. The smaller stomach significantly limits the amount of food that can be eaten at one time, which helps you to feel fuller sooner.
A gastric sleeve can be also be used as a first step for individuals who may not yet be eligible for gastric bypass surgery. The vertical sleeve gastrectomy procedure is an option to help you start losing weight. After a few years, most people lose enough weight to complete the second step of the process.
The procedure is usually performed laparoscopically using minimally invasive surgical techniques.
