Why treat Barrett's esophagus
Barrett's esophagus raises the risk of esophageal cancer, especially when biopsies show dysplasia (precancerous cells). RFA can remove that tissue before it progresses.
How RFA works
During an upper endoscopy under sedation, a device delivers controlled heat energy to the abnormal lining. More than one session is often needed, spaced a few months apart, with follow-up endoscopies to confirm the results.
Recovery
Chest discomfort and trouble swallowing are common for several days. You'll follow a soft or liquid diet for a short time and take acid-reducing medication to help the esophagus heal.
