How Is The Adjustable Gastric Band Inflated?
The silastic band is inflated and adjusted by introducing isotonic solution or saline via a special needle through a small access port positioned under the skin. As the fluid reaches the gastric band, the band swells, increasing the pressure around the outside of the stomach. This decreases the size of the passage between the upper and lower pouches and further restricts the movement of food. Conversely, by removing fluid from the gastric band, pressure is decreased, permitting faster gastric emptying and a greater food intake. Usually, the stomach band is not inflated or “filled” during the actual operation. Most Lap Band surgeons choose to introduce only a small amount of fluid into the band at the time of placement. This is because the stomach tends to expand immediately after surgery.
