Restrictive and malabsorptive technique:
This complex technique makes it possible to limit the quantity of food ingested and the assimilation of these foods by the intestine.
The size of the stomach is reduced by gastrectomy and the small intestine divided into two parts and. The stomach is connected to the part serving to transport food to the large intestine. The part, which serves to transport the digestive secretions of the liver and pancreas, is connected to the end of the small intestine. Thus, the food is digested by the digestive juices and assimilated only on a short portion of the small intestine; most of the food passes directly into the large intestine without being absorbed.
