It is a new treatment for patients who have had a bariatric surgery and regained weight. Through a sedation endoscopy we apply an argon laser in the anastomosis (new communication performed in the bypass surgery between the small stomach and the small intestine).

How does this laser work in the regain of weight?

The application of the argon by endoscopy burns the region of the anastomosis that results after the healing, in a partial closing of the communication canal between the small gastric chamber and the intestine in the by-pass surgery, which takes to an earlier satiety and weight loss.

Can this endoscopic treatment with laser be performed several times?

Some studies have demonstrated that usually 3 argon sessions are necessary in the anastomosis depending on its caliber to get to the caliber close to the ideal that would slow the passage of the food from the stomach to the intestine, providing early satiation and weight loss.

Does this argon laser treatment present any risks?

Every procedure presents risks. There have been cases of bleeding, anemia, intense pain after the surgery and stenosis (excessive closing of the anastomosis) after this procedure. However, many patients contact us to have this procedure due to the chance of having a significant weight loss with a low risk procedure avoiding a more complex surgery.

What result can I expect from this argon laser treatment?

Because it is a complex problem, in patients who have already been operated on, with different causes of weight regaining, the results are unpredicable. In average, the patients lose 3 to 5% of total weight loss per session, what results in an average of 12 to 20% of total weight loss. The work of the multidisciplinary team is very important to reorientate the diet, provide psychological/psychiatric treatment of the anxiety and indication of regular physical activity for the patient to get the best possible result.
