Some of these surgical procedures work by reducing the volume of the stomach, thus restricting food intake. Other procedures work by re-routing the intestines and reducing the absorption of nutrients from the digestive tract.Laparoscopic adjustable gastric banding involves the placement of a silicone band around the upper part of the stomach that restricts the amount of food consumed. Surgeons can adjust the constriction of the band by injecting saline into a port implanted under the skin. Laparoscopic sleeve gastrectomy involves removing up to 80% of the stomach: the sac-shaped stomach is resized and reshaped into a narrow tube with the use of surgical staplers. This technique does not require the implantation of a port.The third technique, a laparoscopic Roux-en-Y gastric bypass the use of surgical staplers to divide the small intestine distal to the duodenum; this allows a 'Roux' limb of intestine to be joined to a small gastric pouch The food stream then bypasses the majority of the stomach and enters directly into the small intestine.
