Like all bariatric procedures, RYGB is laparoscopically performed. The surgery has two parts. First, a small-volume pouch is created in the part of the stomach connected to the esophagus. This formed pouch occupies a volume of approximately 30-50 ml. Unlike sleeve gastrectomy, the rest of the stomach is not removed. But food does not enter this section.
In the second part of the operation, the small intestine is separated and one end is connected to the newly formed gastric sac. The other end is combined with the new digestive tract, ensuring the continuity of the bile pancreatic digestive enzymes path.
