Laparoscopic adjustable gastric banding involves placing an adjustable silicone ring around the junction of the oesophagus and stomach. The Lap Band™ is the best known example of an adjustable gastric band, but is only one of a number of similar products currently available.

How it Works

Adjustable gastric bands work by slowing the entry of food into the stomach, sending satisfaction signals to the brain after eating a smaller amount of food. In order to achieve this, the band needs to be sequentially adjusted with injection of saline (salty water) through a port that is placed underneath the skin of the abdomen. This process often takes between three and six adjustments, in monthly intervals.

Weight Loss

Average weight loss outcomes for adjustable gastric bands in well designed studies are significantly less than that of the gastric bypass or sleeve gastrectomy (average of 10-15% of starting body weight). Weight loss outcomes are also less predicable after adjustable gastric banding; although some people lose as much weight as they would from a gastric bypass or sleeve, up to one third of people struggle to lose any significant weight.

Details and Risks

Although laparoscopic adjustable gastric banding is a safe initial operation, there is growing concern over people needing late reoperations. Two studies have now shown that up to four out of every ten patients with adjustable gastric bands require further surgery for complications in the first ten years. Many of these operations involve removing the band, and in this situation people usually regain all their lost weight.

Due to the lower initial weight loss and concerns about long term complications, we no longer offer this procedure at Aspiring Bariatrics.  We are happy to provide a band adjustment service for patients who have had a band placed elsewhere, and to manage any band related complications.  Please note that patients who have not previously been seen at Aspiring Bariatrics will need to obtain an operation report from their original surgeon and a barium swallow examination.  We can request a barium swallow on your behalf through Pacific Radiology in either Dunedin or Clyde, please click the links for further information about this procedure.
