Laparoscopic gastric banding is a surgery to help with weight loss. The surgeon places a band around the upper part of your stomach to create a small pouch to hold food. The band limits the amount of food you can eat by making you feel full after eating small amounts of food.
After surgery, your doctor can adjust the band to make food pass more slowly or quickly through your stomach.
Laparoscopic adjustable gastric banding (LAGB) is a surgical procedure that involves the placement of an adjustable belt around the upper portion of the stomach using a laparascope. The band is made of silicone and can be tightened by adding saline to fill the band. The band is connected to a port that is placed under the skin of the abdomen. This port is used to introduce or remove saline into the band.
LAGB restricts the size of the stomach and the amount of food it can hold. It slows the passage of food to the intestine. By doing so, signals to the brain from the gut allow for a sensation of fullness and satiety with the consumption of less food. This signal is sent from a small pouch created by the band in the upper stomach. When the pouch fills, the same signal is sent to the brain that occurred previously when the entire stomach filled.
