The procedure is done under general anesthesia. It lasts between 30 minutes and 1 hour and may require 3 days of hospitalization in a clinic.
The technique of the gastric band consists in the division of the stomach into two small pockets: an upper pocket (with a diameter of 15 to 25 cm) and a lower pocket.
Gastric banding in Tunisia is done in the upper part of the stomach, using a silicone ring. Thus, when food is swallowed and chewed well, it is in the upper pouch that it lands. The gastric band is easily adjustable and can be tightened or loosened with a small case. Located under the skin (usually in the abdomen), this box is connected to the band by a small silicone tube.
