Adjustable Gastric Band

The procedure is performed through laparoscopy. It involves placing a silicone adjustable gastric band around the upper part of the stomach, reducing its functional size and emptying time; leaving a reservoir of about 20 to 30 ml as a new stomach.

The band has three parts: the adjustable band itself, a port or reservoir, and a flexible tube that connects both.

The band has a soft, inflatable balloon on the inside that can be filled with saline solution to tighten or loosen its grip. The port or reservoir is placed on the left side of the patient´s body, under the skin, so adjustments can be made by injecting or removing fluid, in order to open or close the band and allow or restrict the passage of food from the pouch to the stomach. A tube connects the port to the band so that liquid can flow. Adjustments are made every two to three months depending on weight loss and patients' satiety effects.

The purpose of the adjustable gastric banding procedure is to induce early satiety, allowing feelings of fullness after eating small portions of food.  The total amount of ingested calories will be diminished and the patient will gradually lose weight, leading to a healthier life, and diminishing the risks of obesity related health conditions.

The placement of the adjustable gastric band is framed in the context of a comprehensive treatment for obesity, since it does not lead to progressive and permanent weight loss by itself. This means that the patient will be asked to follow a diet plan and exercise program in order to obtain the best results from the treatment.

This technique is fully reversible since no anatomical alteration of the stomach is performed, allowing for the band to be removed if necessary.
