Gastric banding

In Europe and Australia, gastric band surgery was long the most frequently performed operation. Meanwhile, this type of surgery is also performed in the USA with increasing frequency, as the band has been approved there since 2001. This type of surgery does not alter any organs.

Surgical technique

The operation is performed laparoscopically, by means of four small 5 mm incisions and a larger 30 mm incision. In gastric banding, a silicone band is placed around the stomach, just below the inlet of the stomach, thus forming a stoma (or small pouch). This considerably reduces the filling volume of the stomach. The band features an interior chamber that can be filled with fluid. This chamber is connected to a reservoir (port) under the skin via a thin tube. The gastric band can be individually adjusted (inflated) via the port. Approximately 4-6 weeks after surgery the band is adjusted for the first time.

How does the gastric band work?


The small pouch considerably reduces food intake as a feeling of satiety is induced at an early stage. The width of the band can be adjusted or inflated significantly via the port by filling the band with fluid. The greater the inflation of the band, the slower the food can pass from the pouch. This results in a longer feeling of satiety. A reduction of approx. 50-60% of the excess weight is to be expected. Gastric band surgery does not alter the affected person’s anatomy. If the band is removed, the stomach returns to normal.
