Gastric Band Surgery (Weight Loss Surgery)
Gastric banding (sometimes called lap banding), is a procedure which involves placing an adjustable silicone band around the upper part of your stomach. It works by restricting the capacity of your stomach, so that you eat less and, over time, lose weight.
Your surgeon will confirm your BMI score and carry out a detailed assessment before deciding if surgery is suitable for you
The operation is performed under general anaesthetic and takes between one and two hours.
A gastric band is usually fitted using keyhole surgery. Keyhole surgery is carried out by making several small cuts on your abdomen. Your surgeon will use small instruments, guided by a laparoscope (a long, thin telescope with a light and camera lens at the tip), to place the band around the top part of your stomach. The band is then connected by a piece of fine latex tubing to the injection port, which is placed just under your skin.
The band is locked in place so that it can’t come undone. Afterwards, your surgeon will close the cuts with two or three stitches or small metal clips.
The gastric band contains a circular balloon which is filled with saline. Your surgeon can add or remove saline from the band after your operation through the injection port. This controls the size of the opening from your stomach and therefore how quickly the pouch empties. You’re likely to have the volume of fluid in your band adjusted two or three times in the first few months after your operation.
What are the risks?
As with any surgery there can be complications such as:
• Blood clots
Specific complications might include:
• An infection around your gastric band, the port or in one of your wounds.
• Injury to your stomach or other organs in your abdomen such as your spleen during the operation.
• The gastric band may slip out of place, leak and deflate.
• Around one in 10 people with a gastric band may need to have it replaced in the future.
Ask your consultant to explain how any risks might apply to you.
