Recent surgical procedure for the management of adult diabetic patients (type 2). And also, it is indicated in those who have morbid obesity.


What is a SASI ?

This new type of bypass was developed in response to the need to solve problems of conventional gastric bypass. It can be considered an evolution of the mini bypass.

In itself, conventional gastric bypass is very effective for:

  • Lose excess weight, especially in patients with morbid obesity.
  • Correct diseases associated with obesity: diabetes mellitus, hypertension, cholesterol and triglyceride problems.
  • Recover the patient’s quality of life.

However, a high price is paid: the patient is dependent on 5 daily medications for the rest of his life: iron, folic acid, vitamin B12, vitamin D and calcium. If the patient does not consume them, he acquires serious deficiency problems.

How is the procedure carried out?

The first step involves the creation of the gastric sleeve, through which about 75% of the stomach is removed.

Then, the surgeon will perform the gastric minibypass, which consists of joining the lower part of the stomach with the lower part of the small intestine, thus, half of the food that is eaten does not pass through the small intestine, reducing the absorption of fats, sugars and calories. Finally, ‘the new stomach’ is connected to the small intestine.
