HOW A SLEEVE GASTRECTOMY WORKS
The sleeve gastrectomy procedure can be the first step before other surgical procedures (e.g., gastric bypass) or it may be employed as a single procedure for weight loss.
- The surgeon creates a small stomach "sleeve” using a stapling device; the rest of the stomach is removed.
- This procedure induces weight loss in part by restricting the amount of food (and therefore calories) that can be eaten without bypassing the intestines and therefore absorbed.
- Weight loss and improvement in parameters of metabolic syndrome are connected with the resection of the stomach and subsequent neurohormonal changes.
- If the sleeve gastrectomy is used as the first step before gastric bypass, in the second step the surgeon attaches a section of the small intestine directly to the stomach pouch, which allows food to bypass a portion of the small intestine.
Sleeve gastrectomy procedure
The majority of weight loss sleeve gastrectomies performed today use a minimally invasive laparoscopic technique. The entire procedure is done through a small incision in your abdomen. Most surgeons prefer this method because it results in shorter hospital stays, faster recoveries, smaller scars, and less pain than open surgical procedures.
