Sleeve Gastrectomy

Normal Normal View of gastrointestinal tract Lap-Band Sleeve Gastrectomy Procedure

The Sleeve Gastrectomy, or Gastric Sleeve, is a minimally invasive laparoscopic procedure that promotes weight loss by permanently removing two–thirds of the stomach (the new stomach looks like a "sleeve," or tube), while preserving the pylorus. The pylorus is the valve that regulates the emptying of the stomach. Retaining the pylorus allows food to trickle slowly out and causes patients to feel full with a small amount of food.

Once the large portion of the stomach is surgically removed following the greater curvature of the stomach, the open edges are attached with staples to form a "sleeve" or tube – permanently reducing the size of the stomach. The stomach is reduced by 85 percent, holding approximately two to five ounces of food and lowering daily caloric intake. Since there is no modification to the bowel, Dumping Syndrome is not as common and there is less nutrient malabsorption after surgery. The elimination of the majority of the stomach also results in the reduction of hunger-causing hormones produced within the stomach. Performed under local anesthesia, the Sleeve Gastrectomy entails approximately five small incisions and takes about an hour to perform. There is no nasogastric tube or drain, allowing patients to return to work and daily activities in about two weeks following the surgery.

Who Is A Good Candidate For The Sleeve Gastrectomy?

The minimally invasive laproscopic Sleeve Gastrectomy is a good weight loss option for patients with less weight to lose. It may also be performed to initiate weight loss and help less stable morbidly obese patients achieve a healthier state before a more extensive procedure can safely be performed.
