- It is performed under general anesthesia and with a minimally invasive laparoscopic approach (4-5 small incisions from 3 mm to 10 mm)
- The intervention consists initially of a restrictive surgical procedure aimed at creating a small vertical gastric pocket, with a volume of about 60 ml, designed to accommodate the food and no longer communicating with the rest of the stomach, which however is left in place.
- The second half of the operation, involves the union (anastomosis) between the gastric pocket and the small intestine, “jumping” (by-passing), however, a stretch of about 180 cm measured from the duodenum.
- The intervention is characterized by the possibility of total reversibility to the original anatomical conditions.
- The mini gastric by-pass has two differences compared to the classic bypass: the creation of a long gastric tank and the packaging of a single anastomosis between the sectioned stomach and the intestine.
- Like the gastric by-pass, the stomach and duodenum are also completely excluded from the transit of food in the gastric mini-pass.
- The mini gastric by-pass causes a drop in body weight with the mechanism of reducing the quantity of food introduced.
The passage of food that has just been chewed, but not digested, in a section of the intestine that was not used to receiving it in this form, determines a stimulation that generates a sense of early satiety of varying degrees.
