Radiofrequency Ablation (RFA) Therapy in Salem & Marion, KY

Radiofrequency ablation (RFA) therapy has been shown to be safe and effective for treating Barrett’s esophagus. Radiofrequency energy (radio waves) is delivered via a catheter to the esophagus to remove diseased tissue while minimizing injury to healthy esophagus tissue. This is called ablation, which means the removal or destruction of abnormal tissue.

While you are sedated, a device is inserted through the mouth into the esophagus and used to deliver a controlled level of energy and power to remove a thin layer of diseased tissue. Less than one second of energy removes tissue to a depth of about one millimeter. The ability to provide a controlled amount of heat to diseased tissue is one mechanism by which this therapy has a lower rate of complications than other forms of ablation therapy.

Larger areas of Barrett’s tissue are treated with the balloon-mounted catheter. Smaller areas are treated with the endoscope-mounted catheter. Both are introduced during an upper endoscopy procedure, which is a thin, flexible tube inserted through a patient’s mouth.

Radiofrequency ablation for Barrett’s esophagus has been used in more than 60,000 cases and the devices are cleared by the U.S. Food and Drug Administration. The balloon-based catheter has been available commercially since January 2005, the endoscope-mounted catheter since January 2007.

A clinical trial by Fleischer, et al. showed that 98.4% of people were free of Barrett’s at a follow-up exam 30 months after two or three RFA treatments. Studies show that when the Barrett’s tissue is removed, it is typically replaced by normal, healthy tissue within three to four weeks. Recent five year follow-up of longer term trials shows that the effects of radiofrequency ablation are durable.

After RFA Therapy Procedure

It is very important that you follow the discharge instructions provided by your doctor or the nursing staff. There are steps you must take to ensure a favorable outcome and to manage your acid reflux. Your doctor will help you:

  • understand possible symptoms that may arise as a result of your treatment and how to treat those symptoms;
  • evaluate your response to the therapy;
  • monitor results over time.

Symptoms after treatment

You may experience chest discomfort, pain, and difficulty swallowing for several days after the procedure. These symptoms can all be managed with medications and will usually go away within three or four days.

Your doctor will prescribe antacid medications to help the healing of the esophagus. For most people, healthy tissue replaces the diseased tissue within three or four weeks.

If you seek care for a digestive issue from any other healthcare provider in the six months following the procedure, the doctor who did the RFA procedure should be consulted.

Contact your physician immediately if you experience any of the following:

  • Significant chest pain
  • Difficulty swallowing
  • Fever
  • Bleeding
  • Abdominal pain
  • Difficulty breathing
  • Vomiting
  • Other warning signs provided by the treating physician

RFA Therapy follow-up

After your RFA treatment, your doctor will schedule a follow-up appointment within two to three months to evaluate your progress. If any remaining Barrett’s tissue is found, additional therapy may be recommended. Clinical studies have demonstrated that Barrett’s tissue can be eliminated with RFA in more than 98% of patients.

Monitoring yourself after RFA Therapy

Regular monitoring of people diagnosed with Barrett’s esophagus is recommended even after RFA therapy. This includes having an upper endoscopy with biopsies on a regular basis for the rest of your life. Your doctor will determine how often you should be evaluated based on the kind of Barrett’s esophagus you had.

Acid reflux treatment

Successful elimination of the Barrett’s esophagus tissue does not cure the acid reflux or GERD that caused Barrett’s. Your doctor will determine how to best manage your long-term acid reflux therapy.
