Sleeve gastrectomy consists of vertical resection of more than 2/3 of the stomach. Recent interest in this operation lies in the fact that the removal of a major part of the stomach, in addition to its restrictive nature, eliminates a quantity of gastric cells (called "parietal cells") which secrete a hormone: the ghrelin; It stimulates the appetite by acting on the level of the central nervous system.
The procedure is performed classically by laparoscopy. It is technically relatively easy to achieve but is characterized by its irreversible side. The risks of immediate postoperative fistulas or abscesses exist but are rare. but the results obtained in the medium term seem excellent.
