As with most surgeries, adjustable gastric banding is performed under general anesthesia with a ventilator to assist with breathing. Barring any exceptional circumstances, adjustable gastric banding is performed laparoscopically. What this means...
is that several small incisions are made at various locations around the abdomen so that the surgeon can gain access to the abdominal cavity. Each incision is rather small and permits the placement of a trocar at each site. A trocar is a special tube, of sorts, that permits surgical instruments and devices to move into the abdominal space.

The upper portion of the stomach is visualized by a camera attached to a long, thin tube. The adjustable gastric banding device (LAPBAND and REALIZE are leading devices) is placed completely around the upper portion of the stomach and fastened. Saline (salt water) is used to inflate the cuff that is around a small portion of the stomach. When the band is inflated, it creates a pouch the acts as a “pre-stomach” As food is swallowed, instead of emptying into the large opening of the stomach, it is temporarily caught in this “virtual pouch.” This leads to a feeling of being full with very small amounts of food.
The end of the device that is anchored to the inside of the stomach wall ends just beneath the skin. As the cuff needs adjustment, a needle can be inserted into this area and saline can either be added or removed to tighten or loosen the cuff. Depending on the patient’s individual anatomy, the cuff or adjustable gastric band is only partially tightened. As the patient adapts to the cuff and the larger remaining portion of the stomach becomes smaller, the physician can tighten the cuff without performing an additional surgery. Adjustments may need to be made as many as six times each year to achieve the best effect.

Other Information
Adjustable gastric banding is a surgical operation intended for weight loss in obese people with a body mass index of at least 35 (obesity starts at BMI 30).
It is best done laparoscopically under general anesthesia. Usually, it takes about one hour. It consists in inserting a hollow plastic band around the stomach. This band is connected by a tubulure to a small box implanted in the abdominal wall. You can constrict the band by filling the box with physiologic serum. Band constriction has a restrictive effect on gastric filling capacity and forces the patient to lower his food intake and it can be modulated by emptying or filling the box with a percutaneous needle. This operation is practised only if the patient is highly motivated for changing his/her eating habits and after a psychiatric assessment.
