Gastric Sleeve surgery, or laparoscopic sleeve gastrectomy, is a type of bariatric surgery in which the size of the stomach is reduced by about 75% to restrict food intake. After the procedure, the stomach is about a quarter of its previous size and can hold much less food. This technique is commonly used and has a high success rate for patients.
Gastric Sleeve surgery involves removing the lateral three-quarters of the stomach with a stapling device. The procedure is done using keyhole or laparoscopic surgery leaving the remaining stomach is more like a tube or ‘sleeve’ than a sac. It is estimated that the remaining stomach has about a 100 to 200ml capacity which works by making you feel full sooner, resulting in you eating less.
