Argon Plasma

The benefits of the bariatric surgery to lose weight are well known, such as remission of obesity associated diseases (like diabetes, hypertension), reduction of death risks, increase of longevity and improvement on the quality of life.

However an important percentage of the patients regain the weight back in some years and this is mainly attributed to the maintenance of the food consumption habits and sedentarism. Such regain of weight is due to the quick emptiness of the food from the new stomach, by dilation of the anastomoses, which causes  more food ingestion.

As far as the anastomoses, gastrointestinal, several techniques for the reduction of its caliper have been attempted, but without considerable results. Based on this concept Dr. Ricardo Fittipaldi from Endogastro Med Service Clinic has been developing a new endoscopic procedure that aims to reduce the exit diameter of the stomach in patients who have already undergone a bariatric surgery and are regaining weight, It is the coagulation with argon plasma.


What is Endoscopic Argon Plasma ?

It is a technique that promotes a thermal coagulation of the mucosa from the gastrointestinal anastomosis and consequently a reduction of its caliper, leading to a delayed gastric emptiness and the food satiety of the patient is extended and lasting.


How does it work?

Three sessions of Argon Plasma application are performed during treatment with intervals of about one and a half month to two between each. Then, a gradual reduction of the anastomosis diameter takes place of about 10 mm. Moreover the patient must be encouraged to do physical activities, with a nutritional and psychological  follow up.


To whom it applies?

The treatment is indicated to:

Patients who have reached their goal (lose > 50% of the weight in excess) and regained 10% or more of the minimum weight after surgery, with anastomosis dilation (>20 mm).

Patients who have not reached their goal and have anastomosis dilation (>20 mm).

Patient who have not regained weight but have already presented anastomosis dilation (>20 mm).


Advantages of the treatment?

The procedure is barely invasive, performed by endoscopy, under sedation, it does not require another surgery.

Basically absent of risks and well tolerated by patients.

Significant weight loss. Studies have shown an average loss of 90% of the weight regained. The purpose of the technique is to be another weapon for treatment on obesity, helping the doctor  fighting the regain of weight after bariatric surgery of gastric by-pass.
