Endoscopic radiofrequency ablation for Barrett's oesophagus with low‑grade dysplasia or no dysplasia

The procedure

The aim of this procedure is to use radiofrequency (heat) energy to destroy the abnormal cells and to promote the growth of healthy normal cells. The medical name for this procedure is 'epithelial radiofrequency ablation'. The procedure is done while the patient is conscious but sedated. The doctor passes an endoscope down the patient's oesophagus. A small probe is then guided to the area of abnormal cells. The probe delivers a few seconds of radiofrequency energy at a time (in pulses) to destroy a thin layer of abnormal cells around the inside of the oesophagus. Repeat treatment sessions may be necessary if any abnormal cells are noted at follow‑up.
