Barrett’s oesophagus refers to a change to the tissue lining of the oesophagus (or gullet) as a response to reflux of fluid from your stomach. About 50% of people with persistent reflux symptoms have Barrett’s change. Overall it is estimated that Barrett’s change occurs in about 10% of the population, but can only be diagnosed by a gastroscopy http://www.waitemataendoscopy.co.nz/endoscopies/ with tissue biopsy.
Why do we worry about Barrett’s oesophagus?
The reason it is important is because, in certain circumstances where there is associated dysplasia of the tissues, it can lead to Oesophageal Cancer.
If there is NO dysplasia on biopsy then the risk of developing cancer is around 0.5% per year, but when High Grade Dysplasia is found on biopsy the cancer risk maybe up to 5% per year.
What can be done about Barrett’s change?
The first treatment is to reduce reflux. Medicines such as omeprazole and other proton pump inhibitors are very effective at this. However this has not been shown to reduce the cancer risk.
If your Barrett’s is of a worrying type your doctor will recommend regular gastroscopy to look for any indication you might develop cancer. This is called surveillance gastroscopy, but it does not remove the Barrett’s tissue.
At Waitematā Endoscopy we now have very effective endoscopic therapy available for those patients with Barrett’s Oesophagus. This is called RadioFrequency Ablation (RFA or HALO TM http://www.waitemataendoscopy.co.nz/endoscopies/ ).
Together with endoscopic removal of any irregular areas RFA has been shown to get rid of over 90% of high risk Barrett’s change and reduce the cancer risk to around 0.2% per year in the very high risk groups.
