What is sleeve gastrectomy?

Also referred to as gastric sleeve surgery, sleeve gastrectomy uses a surgical stapler to remove a large portion of your stomach – up to 85%. The remaining sleeve-shaped portion becomes your “new” stomach, and because it is smaller, you will feel full much more quickly and you will not be able to consume as many calories. Gastric sleeve surgery is a simpler procedure than the gastric bypass procedure since it does not alter the small intestine, and it is also associated with better long-term weight loss than the gastric band, or “lap band.” Gastric sleeve surgery may also be performed prior to a subsequent gastric bypass surgery, enabling very obese patients to lose weight so the bypass portion of their surgery is easier to perform and less risky.

How is the sleeve gastrectomy procedure performed?

Sleeve gastrectomy is performed under general anesthesia using a minimally-invasive approach called laparoscopy, a technique that uses small incisions and is therefore associated with fewer risks and faster recovery. During the procedure, the lower portion of the stomach is carefully removed, leaving the banana-shaped “sleeve” portion in place. Once the new stomach portion has been created, the incision sites are closed and bandages are placed over them. Most sleeve gastrectomy procedures take no more than 90 minutes to perform.

What risks are associated with gastric banding?

Like some other types of weight-loss surgery, sleeve gastrectomy reduces the number of nutrients your body is able to absorb through food; therefore, you will need to take supplements and follow specific dietary guidelines to ensure your body gets the nutrients it needs to stay healthy. However, the nutritional impact of the sleeve procedure is less compared to gastric bypass which also eliminates a portion of your small intestine. The smaller stomach size can also increase the advent of heartburn or nausea, but these issues usually develop after eating too much at one meal.
