Adjustable gastric band, or Lap-Band, surgery is a “restrictive” operation, meaning that it limits food intake and does not interfere with the normal digestive process. In this procedure, a silicone band is wrapped around the upper part of the stomach, creating a small stomach pouch. The lower, larger part of the stomach sits below the band. The two parts of the stomach remain connected through a narrowing created by the band. The band thus restricts the amount of food you can consume at a single meal. Food can still pass from the upper to the lower stomach regions, however, it moves through the new opening slowly, so that you feel full longer. The procedure is performed laparoscopically, using 5 small skin
An important aspect of the Lap-Band (offered by Clarity Bariatrics) is that it can be easily adjusted after surgery. This is accomplished by using a fine needle to gain access to a small reservoir that is positioned well  under the skin and fat of the abdomen at the time of surgery.
