Gastric Bypass

Sleeve Gastrectomy

Sleeve Gastrectomy

This newer minimally invasive surgery is gaining popularity among doctors but was first introduced in 1981. This procedure generates weight loss by removing a portion of the stomach, decreasing its size by 70 to 80 percent. The remaining stomach takes on a tube or sleeve-like shape. This non-reversible surgery limits the stomach's capacity to about 3-7 ounces, which significantly decreases the amount of food that can be eaten.

Even though the procedure significantly reduces the size of the stomach, it still allows your stomach to function normally. Most food items can be consumed but in smaller amounts. Research has shown that because stomach tissue is removed, Ghrelin, a hunger-inducing hormone secreted by the stomach, is decreased for about six months after surgery, leading to decreased appetite.¹  For these reasons, many surgeons and patients feel this surgery is superior.

The weight loss from this procedure is similar to gastric bypass and much greater than gastric banding systems.

This surgery is performed under general anesthesia and takes about one to two hours. Since this surgery is laparoscopic, the surgeon will make small incisions in your abdomen instead of one big incision and insert a special camera and the surgical instruments that will remove part of your stomach. Once a portion of your stomach is removed, the remaining "sleeve" is closed.

Advantages of Sleeve Gastrectomy

  • Less invasive than gastric bypass.
  • No rerouting of the intestines.
  • Stomach empties normally into the small intestine.
  • Does not require an implanted device.
  • Better for patients with prior surgery or medical conditions.
  • Fewer complications and malabsorption issues.
  • Little risk of "dumping syndrome," a condition where ingested foods bypass the stomach too rapidly and enter the small intestine largely undigested.
  • Nutritional supplementation is not as great as with gastric bypass.
  • Rapid weight loss within a year.
  • Weight loss greater than with gastric banding.
  • Can be converted later to gastric bypass if desired.

Risks associated with Sleeve Gastrectomy

  • Leakage of the sleeve (stomach) leading to infection.
  • The stomach can stretch and weight may be regained over time.
  • Need for additional weight loss surgery.
  • Malabsorption.
  • Bleeding.
  • Blood clots in legs or clots to lung.
  • Anesthesia complications.
  • Death
