Gastric band to bypass conversion is a surgical procedure that combines the removal of a gastric band with the creation of a gastric bypass.
Gastric bands are adjustable devices that are placed around the stomach to restrict food intake. Gastric bypasses are more restrictive procedures that involve creating a smaller stomach pouch and bypassing part of the small intestine. They tend to be associated with higher levels of weight loss and used for the most overweight or obese patients.
Who is gastric band to bypass conversion for?
There are a few reasons why you might want to have a gastric band to bypass conversion:
- Disappointing results: If you are not losing weight or are gaining weight with the band in place, it may be time to have it removed and replaced with a more restrictive procedure.
- Complications: If you are experiencing issues such as erosion, infection, or ulcers caused by the gastric band, then you may need to have it removed. The bypass is an alternative weight loss procedure which does not involve having a ‘device’ inserted.
- More permanent weight loss solution: Gastric bands are not permanent devices. If you are looking for a more permanent weight loss solution, you may want to consider having a gastric bypass to reduce the size of your stomach permanently.
Gastric band to bypass procedure
Gastric band to bypass conversion is a more complex procedure than either gastric banding or gastric bypass alone. It is usually performed laparoscopically, but it may require open surgery in some cases. The procedure typically takes 2-3 hours to perform.
The steps involved are:
- Gastric Band Removal: The first step is the removal of the gastric band. This is typically done using minimally invasive techniques, such as laparoscopy, where small incisions are made in the abdomen for surgical instruments.
- Revision of the Stomach: Once the band is removed, the surgeon modifies the stomach to create a smaller pouch. This pouch restricts the amount of food that can be consumed, leading to decreased calorie intake.
- Bypassing the Intestine: In this step, the surgeon reroutes a section of the small intestine, connecting it to the newly created stomach pouch. This allows food to bypass a portion of the small intestine, limiting nutrient absorption and further promoting weight loss.
Potential risks/complications
The risks of gastric band to bypass conversion are similar to the risks of gastric band insertion and gastric bypass. These risks include bleeding, infection, and complications related to anaesthetic. The potential complications will be fully explained at consultation, prior to surgery.
If you are considering having a gastric band to bypass conversion, it is important to fully understand the potential risks as well as the possible benefits of the procedure.
Gastric band to bypass advice
Remember, you will need to make lifestyle changes after gastric band to bypass conversion. Even though the band will be removed and the bypass will be created, you will still need to eat a healthy diet and exercise regularly in order to maintain your weight loss.
Gastric band to bypass conversion is a serious surgery, but it can be a good option for people who are experiencing complications with their gastric band or who have decided that they want a more permanent weight loss solution.
