Endoscopic Barrett's ablation

Endoscopic ablation of dysplasia (precancerous changes) or early cancer in Barrett’s esophagus involves using techniques to destroy the abnormal tissue through the use of instruments that can be used through an endoscope (a tube passed through the mouth into the esophagus) without the need for surgery. The two most common techniques are the use of photodynamic therapy (PDT) and radiofrequency ablation (trade name is Barrx). Both techniques involve using energy that heats the tissue lining the esophagus causing death to the abnormal cells. The body then replaces the damaged abnormal tissue with healthy normal cells. PDT uses a laser light source to heat up cells in the esophagus that have been made sensitive to light by injecting a medication into the blood stream. Barrx uses radiofrequency energy to heat up the cells lining the esophagus causing them to die.
