Laproscopic Adjustable Gastric Band “Lap Band”
There are several types of bariatric sugery, restrictive types of weight loss sugery. In this study we are evaluating Adjustable gastric banding.
Laparoscopic gastric banding surgery is a commonly used surgery for weight loss for patients who are markedly overweight or overweight and have medical problems, such as sleep apnea.
Briefly, it involves placing a silicone band around the upper stomach to restrict food intake. This creates a small pouch and a narrow passage to the lower stomach. This small passage delays the emptying of food from the pouch and causes a feeling of fullness. The band is then attached to a port that is placed underneath the skin, and allows for the surgeon to adjust the band size by adjusting the volume of fluid in the band. By controlling the band size in this fashion, the band reduces the amount of food that can be eaten and leads to feeling of fullness and weight loss.
The surgery is done laparoscopically, which means 5-6 small skin incisions are made and the surgery performed through these. The operation typically takes about one hour, and involved an overnight hospital stay.
Average weight loss at 2 years following surgery, is 40-45% of excess body weight.
