Laparoscopic Adjustable Banding
Laparoscopic Adjustable Banding is a surgically placed band that goes around the upper portion of the stomach. The inner balloon is accessed by a port under the skin, on the abdominal wall. At regular intervals sterile water can be injected, increasing restriction, until adequate weight loss is achieved. This creates an hour glass shape out of the upper most portion of the stomach. It is a slower weight loss over 2 - 3 years and requires more frequent follow-up and adjustments in the surgeon's office. There is no malabsorption, but because of decreased volume of intake, vitamin supplementation is still required. The stomach is not divided and the small bowel is unaltered during this procedure.
Gastric banding achieves 40-60% of excess weight loss and may prove to be higher with time. It has the lowest mortality, and the chances of leaking are very slim due to the fact that it does not divide any organs such as the stomach or small bowel.
- Restricts the amount of food consumed at a meal
- Food consumed passes through the digestive tract in the usual order, allowing it to be fully absorbed into the body
- In multiple studies involving over 3,000 patients, excess weight loss ranged from 28-87%, with a minimum of 2 year postoperative follow-up
- Band is adjustable to increase or decrease restriction
- Surgery is reversible
- Band erosion into the stomach wall or tearing in the stomach wall may require additional operation
- Access port leakage or twisting may require additional operation
- May not provide the necessary feeling of satisfaction that one has had enough to eat
- Nausea and vomiting
- Pouch dilatation
- Band migration and slippage, also known as gastric prolapse, may require re-operation
