Introduction To Gastric Banding

One of the most common of Bariatric Surgeries, performed to reduce the volume of the stomach in obese or overweight patients is Gastric banding. This involves putting a silicon band , strapped around the upper portion of the stomach. The system helps the patient eat less by limiting the amount of food that can be eaten at one time and increasing the time it takes for food to be digested.

Procedure For Gastric Banding

During the gastric banding Surgery, a new and a smaller stomach is created with a line of staples, and is connected to the loop of small bowel. A small silicone band is placed around the upper stomach. This creates a small reservoir and a relatively restricted passage to the lower stomach. The opening between the pouch and the lower part of the stomach can be adjusted in size by inflating or deflating the hollow band. Inflating the band makes the opening smaller, causing food to pass more slowly. Deflating the band makes it wider, causes food to pass more quickly.

How Does Gastric Band Surgery Work ?

The gastric band is a hollow tube in the shape of a ring. Your surgeon can inject a saline solution into the band which then causes it to expand and so tighten around the stomach. If this band needs tightening then more solution is added. If it needs loosening then he/she will remove some of the solution. This is often referred to as adjustments and fills.

How Is The Gastric Band Adjusted ?

The surgeon will have a small handheld device, similar to a remote control. He/she will also place a small transmitter onto the patient’s chest – where the receiver is located. He/she will press a button on the handheld device which causes a signal to be sent to the transmitter and the receiver. The receiver then sends that signal to the tiny microchip inside the ring. This tells the ring to expand or contract.

What is especially useful is that the surgeon can receive feedback about the current state of the ring and can make any necessary changes.

The placement of the band that is the Gastric Lap Band creates a small pouch at the top of the stomach which holds approximately 50mls. This pouch 'fills' with food quickly and the passage of food from the top to the bottom of the stomach is slowed. As the upper part of the stomach believes it is 'full' the message to the brain is that the stomach is full and this sensation helps the person to eat smaller portions, eat less and therefore lose weight over time.

During gastric banding, a silicone band is placed around the upper stomach creating a small reservoir and a restricted passage to the lower stomach. The average length of surgery is about 2 hours.
