In this new blog post we want to focus on the main benefits of gastric sleeve. It is also known as a gastric tube, as a vertical or tubular gastrectomy or as a gastric sleeve. Different ways of referring to the same thing – one of the most common techniques in the field of bariatric surgery.

We are talking about a restrictive type technique. Why? Because what is done is to reduce the size of the stomach to, consequently, reduce food intake. The stomach is divided into two parts vertically using staples. The next step is for the bariatric surgeon to remove the residual part of the stomach, the greater curvature. This represents between 80% and 90% of the gastric cavity.

It is as we say a restrictive and not malabsorptive technique. By removing approximately 85% of the stomach there is a marked reduction in the production of ghrelin, the hunger hormone. In other words, we reduce appetite and encourage weight loss.

The gastric sleeve technique requires general anesthesia and lasts about an hour. Afterwards, the patient will have to be admitted for 2 or 3 days. The intervention is done with laparoscopy. What the Laparoscopic Surgery specialist does is make small incisions in the abdomen to insert a camera and the surgical material necessary for the intervention. We insist that it is a minimally invasive technique, almost painless and with a quick recovery.

The postoperative period of the gastric sleeve is divided into phases. In the first you can eat only liquid food. Physical activity will have to be introduced gradually.

In summary, its advantages are:

  • Minimally invasive technique.
  • You lose weight very fast.
  • The patient is satisfied faster with small amounts of food.
  • The production of ghrelin, the hunger hormone, is reduced.
  • It does not affect the absorption of nutrients.
