The Stretta procedure is a minimally invasive, non-surgical way to treat gastroesophageal reflux disease, or GERD. The procedure is performed using an endoscope (a thin, flexible, lighted tube which is passed down the throat into the esophagus), involves no cutting or sewing, and leaves no skin incisions or scars.

The procedure can be performed as an outpatient. Patients typically return to normal activities the following day.

Here's how it works:

The Stretta device is a thin tube, or catheter, with a balloon at the end. With the patient conscious but under heavy sedation, the catheter is guided through the endoscope which is placed in the esophagus just above the stomach. There the balloon is inflated, exposing four sharp probes on the outside of the balloon. The probes then discharge high-frequency radio waves into the muscle at the top of the stomach which is called the lower esophageal sphincter (LES). After several rounds of this process, the LES -- which is too loose in GERD patients -- becomes much tighter. Tightening the LES keeps stomach acid from splashing up into the esophagus.

How Much Does the Stretta Procedure Improve GERD Symptoms?

At least one study has shown that one year after undergoing the Stretta procedure, nearly two-thirds of the patients were able to stop taking all of their acid-blocking medicines. Overall, the patients reported feeling significantly better six months after treatment -- and even better at the 12-month mark.

Individual results may vary and the long term benefits are uncertain. This procedure is also not without risk; there is potential for serious complications.

Other Options for GERD Treatment

A less invasive option for treating GERD without medication includes endoscopic sutures (stitches). The FDA approved this procedure based on its safety but was unsure of its effectiveness. Other techniques are now in clinical trials.
