How is Gastric Banding Performed?

The gastric banding procedure is a less invasive procedure consisting of several steps. With the first step, the surgeon makes several small incisions along the abdomen. A small medical camera will be inserted through one of the small incisions into the abdominal cavity. This gives the surgeon a good view of the stomach. A small silicone band is placed upon the upper portion of the stomach, creating a small stomach pouch. The small stomach pouch will restrict the amount of food that can be consumed. The recipient of the band will eat less.


The silicone band is then attached to a tube and the tube is connected to a port. This port helps adjust the silicone band and is adjusted on a regular basis by the surgeon often in the outpatient setting. Saline or some other type of fluid is injected or extracted through the port, which enables constriction or release of the band along the upper portion of the stomach.


The silicone band can be adjusted by the surgeon on a regular basis, depending on the needs of the gastric band recipient. The new stomach pouch can hold anywhere from ¼ of a cup of food up to 1 full cup. The procedure is reversible.


Someone undergoing the procedure can expect to lose 20% to 50% of excess weight loss within the time span of 1 to 2 years.
