Sleeve Gastrectomy

This surgery can be done by making a large incision in the abdomen (an open procedure) or by making several small incisions and using small instruments and a camera to guide the surgery (laparoscopic approach).

Restrictive operations like gastric sleeve surgery make the stomach smaller and help people lose weight. With a smaller stomach, you will feel full a lot quicker than you are used to. This means that you will need to make big lifelong changes in how you eat-including smaller portion sizes and different foods-in order to lose weight. The sensation of hunger has been linked to grehlin production from the stomach. After sleeve gastrectomy grehlin levels fall causing many patients to lose their hunger sensations and the desire to eat.

More than half of your stomach is removed, leaving a thin vertical sleeve, or tube, that is about the size of a banana. Surgical staples keep your new stomach closed. Because part of your stomach has been removed, this is not reversible.

Non reversible, moderately invasive laparoscopic procedure, removing a 75% of the stomach. Long term results are unknown. The sleeve can leak, become too narrow or stretch with time.
