This technique consists of the laparoscopic placement of an adjustable silicon band around the uppermost part of the stomach. This technique allows the creation of a small proximal pouch (10 to 15 cc). The dilation of the pouch through small food intakes is perceived by our brain as a total dilation of the stomach and therefore induces an early feeling of fullness.
The device is equipped with a small reservoir that allows adjustments of the band opening.
In this operation, in order to induce an early feeling of fullness, a large part of the stomach is removed and the remaining part takes the shape of a tube. This procedure can be performed laparoscopically.
With this technique, a pouch is created by removing a large part of the stomach. The pouch is then connected to the final segment of the small intestine, thus bypassing almost the whole intestine. Ingested food is therefore barely digested.
With this technique, the stomach is cut vertically in order to create a small proximal pouch (restriction). This pouch is directly connected to the jejunum, thereby causing food to bypass a large part of the stomach, the duodenum and proximal jejunum. The functional part of the intestine is thus reduced to 40-50 cm. This causes malabsorption resulting in weight loss.
