It is the most commonly performed type of gastric bypass surgery. It is performed laparoscopically.
In roux-en-y gastric bypass, a small pouch of stomach is created which is separate from the rest of the stomach. This pouch is then attached to a part of the small intestine. The food passes directly from the stomach pouch to middle part of small intestine, bypassing the rest of the stomach and first section of the small intestine. It works by reducing the amount of food eaten by an individual per meal. It also has a malabsorbtive effect along with the restrictive element.
