Laparoscopic Sleeve Gastrectomy is a restrictive bariatric surgery procedure, in which approximately 85% of the stomach is removed, leaving a cylindrical, or sleeve-shaped stomach. Unlike other forms of bariatric surgery, the outlet valve and the nerves to the stomach remain intact and, while the stomach is drastically reduced in size, its function is preserved. The sleeve gastrectomy is not reversible.
With the sleeve gastrectomy, the new sleeve-shaped stomach is larger than the stomach pouch created during the Roux-En-Y Gastric Bypass, and is about the size of a banana. Weight loss occurs because the reduced stomach volume only allows for the ingestion of a small amount of food, which increases the feeling of fullness. Also, the production of Ghrelin, the “hunger hormone,” is drastically reduced, therefore enabling patients to control hunger and cravings and enhancing weight loss.
