Like all bariatric interventions, Mini Gastric Bypass surgery is laparoscopically performed. The surgery has two parts. First, a long and thin pouch is created in the part of the stomach that is connected to the esophagus. Unlike sleeve gastrectomy, the rest of the stomach is not removed. But food does not enter this section.
In the second part of the surgery, the small intestine is connected to the newly formed gastric sac without being separated.
