What Is Laparoscopic Roux en Y Gastric Bypass?
This gastric bypass surgery procedure is also done via the laparoscopic or keyhole technique. A small pouch of upper stomach is created and separated from the rest of the stomach using specially designed surgical staplers. This allows the patient to eat a small amount.
Food is then directed further down the path of the small intestine. The length of intestines left to absorb calories is shorter causing a certain degree of malabsorption and reducing the amount of calories and nutrients absorbed.
