What Is Radiofrequency Treatment?


Updated May 21, 2008

Question: What Is Radiofrequency Treatment?
A minimally invasive procedure using an endoscope that is done on an outpatient basis. It is used to treat gastroesophageal reflux disease (GERD).

Using a endoscope, a physician will use radiofrequency waves to create heat lesions in the lower esophageal sphincter (LES) and the uppermost part of the stomach. This will help the tissue in this area constrict and will improve the function of the LES. The result will be a reduction of acid reflux because the LES doesn't relax when it shouldn't.

Current studies of this procedure shows that, when used by a trained physician, the radiofrequency procedure is generally as safe as a routine endoscopy procedure.

Benefits of this procedures are that it is less invasive than laparoscopic surgery, and has fewer side effects. Side effects can include a sore throat and minor chest pain right after the procedure. It also takes time for the function of the LES to improve. Therefore, a patient may still need to take anti-reflux medication for symptoms until the LES function improves.
