Barr X (Radiofrequency Ablation) for Barrett’s Oesophagus.
Radiofrequency Ablation (RFA) is an established endoscopic treatment in which the Barretts tissue is exposed to a defined heat energy to destroy the abnormal tissue.
RFA was first used to treat Barretts oesophagus without dysplasia in 2005 and then subsequently used to treat both low and high grade dysplasia. More than 50 worldwide clinical studies, including several form the national UK RFA database, have demonstrated the safety and long term effectiveness of RFA for complete removal of Barretts as well as reducing progression to oesophageal cancer.
How does Radiofrequency Ablation Work?
RFA for Barretts oesophagus is performed in the endoscopy unit on a day case basis under sedation by an experienced gastroenterologist.
An electrode mounted on a balloon catheter (HALO 360) or an electrode placed directly onto the endoscope is placed into the oesophagus and used to deliver heat energy directly to the Barretts lining of the oesophagus. The choice of HALO device is determined by the amount (length) of Barretts that requires treatment. The procedure typically takes 30 to 30 minutes and leads to ablation of the tissue. The treated tissue in the oesophagus sloughs off over the next 3-5 days following the procedure and over a period of 6-10 weeks this is replaced by normal (squamous) lining of the oesophagus.
What our patients say
We were very pleased to receive first class reassurance, advice, treatment, and aftercare. We would definitely recommend Dr. Campbell to anyone in need of an excellent Doctor. His secretary Sarah was also very helpful and most competent.
Combining superb expert knowledge , outstanding technical skills (colonoscopic endoscopic mucosal resection), extremely good listening and communication skills with a down to earth practical approach to any difficulties, Dr Willert made me fully very safe and confident in his care. I am very pleased to have been referred to him with my problem.
