Laparoscopic adjustable banding is the most common surgery for obesity in Australia and Europe. It has been in use in these countries since 1993. The United States FDA granted approval of the LAP-BAND in 2001.
Recent studies show that patients lose 30-40% of their excess weight (average weight loss) in the first two years after surgery. Weight loss slowly progresses to 50% of excess weight being lost at three years after surgery.
Most people maintain this weight loss over five years. However, up to 20% of patients with LAP-BAND surgery fail long-term weight loss.
