What is laparoscopic adjustable gastric banding (LAGB)?

UCLA Health

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 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.
