LAP-BAND (Adjustable Gastric Banding System)
LAP-BAND is the most common form of weight loss surgery in Europe and Australia . Approved by the FDA, it is performed laparoscopically. It is one of the least invasive approaches, because neither the stomach nor the intestine is cut.
The LAP-BAND System involves the laparoscopic placement of a removable hollow silastic band around the upper part of the stomach. This band divides the stomach into a small upper pouch above the band and a larger pouch below the band. This small gastric pouch limits the amount of food that a patient can eat at any one time, and will result in a feeling of fullness after eating a small amount of food.
Estimated weight loss is approximately 40–60% of one's excess weight to be achieved over 2 years.
Advantages: operations are easier to perform and are generally safer than malabsorptive operations. LAGB is usually done via laparoscopy, which uses smaller incisions, creates less tissue damage, and involves shorter operating time and hospital stays than open procedures.
Disadvantages: Patients who undergo gastric banding generally lose less weight than patients who have bypass surgery, and are less likely to maintain weight loss over the long term.
Patients generally lose about half of their excess body weight in the first year after gastric band surgery.
However, in the first 3 to 5 years after LAGB patients may regain some of the weight they lost. By 10 years, as few as 20 percent of patients have kept the weight off.
Some patients regain weight by eating high-calorie soft foods that easily pass through the opening to the stomach. Others are unable to change their eating habits and do not lose much weight to begin with. Successful results depend on the patient’s willingness to adopt a long-term plan of healthy eating and regular physical activity.
