In this procedure an adjustable silicon "band" is place around the beginning of the stomach so as to create a small pouch (typically 30-50 ml) hence providing an early feeling of fullness. It is gradually released into the rest of the intestine. This is a purely restrictive procedure. It provides moderate amount of weight loss (50% of excess weight loss) and is reversible. The band needs to be adjusted in the initial days after surgery. Some people will begin to regain some of the lost weight after a few years. The advantage is that it can be reversed by removing the band by another surgery.
