Gastric Banding

What is Laparoscopic Gastric Band (LAGB) surgery?

A laparoscopic adjustable gastric band commonly called a lap-band or LAGB is an inflatable silicone device placed around the top portion of the stomach. The smaller stomach then creates a rapid feeling of ‘fullness’ or satiety when you eat, and the Band at the top of the stomach helps maintain a level of adjustable ‘restriction’ when you eat. If people rely on the feeling of restriction or fullness too much, however, they end up stretching their oesophagus and stomach, which will lead to reflux and band removal.

How does a Gastric Band work?

The LAGB is a device manufactured in many different forms, but all have a similar underlying design. The Band is a silicone ring with a balloon similar to a tyre tube running around the inside of it. This inflatable area is connected by hollow tubing to a port (a disc a little larger than a 10-cent piece) which sits under the skin of your abdomen. When fluid is put into the port, it inflates the balloon, reducing the space for food to pass into your stomach.

How the Gastric Band causes weight loss

The Band will slow you down when you eat (so it may take 20 minutes to have half a sandwich) and will suppress your appetite so you can stop eating after a small amount of food. The Band itself does not make you lose weight – meal planning and conscious portion reduction needed. The Band doesn’t force you to stop eating, and a common mistake is for people to eat even when they are no longer hungry.

When you eat, food moves slowly into the stomach and food sitting above the Band stretches some of the nerves that help reduce your hunger. The amount of stomach above the Band is about the size of a thumbnail. You will be consuming about 600-800 calories per day when losing weight and 1000-1200 calories per day when keeping your weight stable.

Gastric Band benefits

  • The Band is probably the safest effective procedure developed to allow long-term weight loss. Other operations, although also performed by keyhole surgery, are larger and therefore riskier.
  • The Band will cause scarring around your upper stomach but otherwise does not change the way your insides are put together.
  • The Band is easier to remove than prosthetics used in other operations. However, removal of the Band invariably leads to weight regain.
  • The hospital stay and time off work is less than for other weight reduction operations.

Gastric Band combined with an imbrication/plication of the stomach

After placing a Gastric Band, it is possible to place extra sutures in the stomach to reduce its volume from over 1.2 litres to about 350-400 cc. This is a larger and riskier operation than a normal Gastric Band, however it creates a procedure that sits halfway between Sleeve and a Band. The Band does not need to be as tight, as the stomach below it is small rather than normal-sized.

Gastric Band drawbacks

  • The Band requires quite significant long-term compliance to achieve and maintain weight loss. This requires a degree of retraining, and if you are not able to retrain you will not lose weight. About 10-20% of people find that they are not able to use the Band effectively early on, and by 10 years 30-50% have required band removal or revision.
  • There will be some foods you will not be able to eat after the operation. These vary from person to person but typically include white bread, chicken, many red meats, and fibrous fruit and vegetables.
  • The Band is a mechanical device, and like all mechanical devices it can ‘break’. Although the majority of mechanical problems can be fixed, this does mean having another operation. If the band problem is not fixed, about 95% of people will put their weight back on.

Why does the weight return when the Band is removed?

Your weight problem is a lifelong illness. If you stop taking treatment (the Band), the illness will return. This is similar to other lifelong diseases, such as asthma or high blood pressure, in that the treatments only work while they are being taken.

Suitable candidates for a gastric band

In general, weight loss surgery is a good option for people who:

  • are very overweight
  • have medical or other problems caused by their weight
  • have tried for several years to lose weight with other methods
  • are prepared to go ahead with the follow-up after surgery.

Essentially, the risks of the surgery need to be balanced against the risks of not having surgery. As you are aware, there are many different surgical options available, and it would be silly to suggest that one solution will suit everyone. It is essential to know about the other options as well to help you make a more balanced decision. Please read the General Information booklet for further details.

Dieting first

You do need to try dieting before undergoing LAGB surgery. This is to help you get an understanding of the energy content of foods and the importance of exercise.

Robotic Surgery

Robot Assisted Bariatric Surgery

Robotic surgery is a more modern form of keyhole surgery. It improves a surgeon’s dexterity and movement precision, reduces tremor and fatigue and allows access into cramped areas of the abdomen. Robot assisted surgery is particularly beneficial for bariatric patients. At Upper GI Surgery we offer the option of robotic bariatric surgery for our patients.
