It's new. And this should significantly improve patient comfort. A technique to treat microwave cancerous tumors located in the liver, kidneys, lungs or bones is applied for five months by the hospital in Pau.It completes a very interesting method used for ten years radio frequency.
This process involves placing an electrode into a tumor, which was destroyed by causing tissue heating. But it has a drawback. Because it does not treat tumors larger than three centimeters, or those located near blood vessels.
Moreover, because of where they are placed, some tumors can not be surgically removed from. Which usually means resorting to chemical processes.
A needle and a screen
The new technique developed in Italy, and authorized in France since 2010, has overcome these difficulties, "said Christophe Gautier, head of the hospital. It involves introducing into the tumor a special needle of 1.5 mm thick. The radiologist who performs this procedure has to do a screen which allows ultrasound to check the smooth running of things.
The needle is connected to a generator. The microwaves that distributes its end can destroy the tumor necrosis by heat. No burning occurs provided at the patient's skin. The result of ablation, which can last about ten minutes, the scanner is controlled.
The process can be performed on a person under general anesthesia or in part. It has several advantages.
It not only necrosis of the tumor more rapidly and more important. But it is also less "invasive," said Olivier Bonnefoy, the interventional radiologist who is responsible for the implementation of this new technique in Pau.
If no complications arise, a patient treated in this way can in fact leave his home the next day, having a simple patch affixed to the location of the skin where the needle was inserted. This is not the case for surgery, which usually requires several days of hospitalization. Moreover, it says in the hospital, the complication rate remains low.
