Whipple Procedure Surgeon

The RFA Procedure

The RFA Procedure is performed either percutaneously (through the skin), laparoscopically (through a scope) or with an open incision. In either case, the patient experiences minimal discomfort and most can go home the same day. After the patient is sedated and given a local anesthetic, the physician uses CT or ultrasound to visually guide a needle into the lesion. An array of wires, guided through the needle, spread out into the lesion in a starburst form to infiltrate the lesion. Some of these wires contain a tiny thermometer by which the temperature of the surrounding tissue can be measured. These wires are attached to a generator that produces alternating current in the controllable range of radio waves.
