The laparoscopic adjustable gastric band (Lap-Band) is used to assist people in losing weight. It requires a surgical procedure in which an inflatable band is used to create a smaller stomach pouch to limit food intake and reduce appetite.

LABG is also commonly referred to as the LAP-BAND. This is performed for patients that desire and are working toward weight loss and have found diet and exercise alone to be ineffective. With the use of the LAP-BAND patients can lose an average of 30-50% of their excess body weight. This surgery usually involve a one day stay in the hospital and back to work within 2 weeks.
Laparoscopic adjustable gastric banding is surgery to make the stomach smaller. It is done to help people lose weight. The surgery limits the amount of food the stomach can hold. This helps you eat less and feel full sooner.
Adjustable gastric banding is done through several small cuts, called incisions, in the belly. The doctor will place small surgical tools and a camera through the incisions. The doctor will then wrap a device around the upper part of your stomach to form a ring. Attached to the ring is a thin tube leading to an access port that is left under the skin. The access port is the place where the doctor puts in a needle to add or take away saline. Adding saline tightens the band and makes the stomach smaller. The doctor can take away saline if the ring is too tight.
During surgery, the band is not inflated. You will need to recover from surgery before the band is adjusted for weight loss. This is usually 4 to 6 weeks after surgery.
Another name for this surgery is gastric banding. Sometimes people refer to it by brand names, for example the Lap-Band System or the Realize Band.

Laparoscopic adjustable gastric banding is a procedure in which a silicone inflatable band is placed around the top portion of the stomach, creating a small gastric pouch above the device itself. This newly created pouch holds approximately 1/2 to one cup of food at a time and helps restrict the amount of food that is eaten. The mechanism by which the band works is to decrease food intake and thereby calorie intake. The stomach is not cut and the anatomy is not altered during this process.

LAGB can improve diabetes in morbidly obese patients. Although remission of diabetes after this operation is less common than with gastric bypass surgery and the efficacy is more strictly linked with the weight loss effect of the procedure, gastric banding may be a valuable alternative option in selected patients.
Gastric banding involves encircling the upper part of the stomach with a band-like, saline-filled tube just distal to the gastroesophageal junction. The amount of restriction may be adjusted by injecting or withdrawing saline solution from the hollow core of the band through a subcutaneous port.
