What are the different types of weight loss surgery?
There are a number of different types of weight loss surgery. Some work on the basis of restricting the amount of food a person can eat and others on the amount of fat that is absorbed by the body from food. Some work on a combination of the two.
For many people, weight loss surgery (or bariatric surgery as it is also known) is a safe and effective last-resort to help people with obesity issues lose weight. For some however complications do arise, which may result in a compensation claim for negligent weight loss surgery being paid.
It’s vital that the correct type of weight loss surgery is chosen for you
Below you can see the different types of weight loss surgery that our team of expert bariatric solicitors have experience in bringing compensation claims for.
Biliopancreatic Diversion (BPD surgery)
In BPD surgery, the lower 2/3rds of the stomach are removed and the stomach is reattached lower down the small intestine. This has the dual combination of restricting intake by reducing the size of the stomach and also reduction absorption, by bypassing some of the small bowel (where nutrients, including fats are absorbed).
Duodenal switch (DS) bypass
The duodenal switch is basically a combination of the sleeve gastrectomy, so most of the stomach is removed, and then a modified BPD. More of the small bowel is bypassed than in a Roux-en-Y bypass.
An intra-gastric balloon is a small balloon that is placed endoscopically down the gullet and into the stomach. It is then inflated to occupy a large amount of the stomach and again physically restrict the amount of food in the stomach at any one time. Usually the balloons are removed (again endoscopically) after 1 year.
Adjustable gastric band
The gastric band is a silicone ring that is placed around the upper portion of the stomach. The ring is connected to a tube that in turn leads to a small port that is positioned just under the skin beneath the rib cage. The band is tightened and loosened by injecting or withdrawing saline (by inserting a needle and syringe into the port). The idea is that the band is tightened to create a small pouch above the band and that physically restricts the amount of food that can be eaten at any one time. When this smaller pouch is full the stomach is “tricked” into thinking it is full.
The Roux-en-Y works by stapling off about ¾ of the stomach to create a smaller gastric pouch and then splitting the small bowel and connecting one end to this smaller pouch and the other to lower down the small bowel but not usually bypassing as much as with the BPD. Unlike a gastric band and the balloon procedure, a bypass is irreversible.
A sleeve gastrectomy is a procedure whereby approximately 2/3 of the stomach is removed and therefore again this restricts the amount of food physically in the stomach at any one time. The small bowel is not affected though unlike the bypass procedures detailed above.
