The cells that line the lower part of the oesophagus (gullet)
called ‘squamous epithelium’ are normally pinkish-white; When these
change to become red and arranged in columns like the cells that
line the intestine this is called Barrett’s oesophagus
Barrett’s oesophagus can be caused by reflux of stomach acid and
bile into the oesophagus causing irritation and inflammation.
Normally a valve in the stomach retains the acid but in patients
with Barrett's oesophagus, this valve has been weakened or moved.
Although a weak valve is common, only one in ten people with acid
reflux or heartburn symptoms develop Barrett’s oesophagus.
For many people, Barrett's oesophagus does not
cause any problems. However, in around 10% of patients this can
develop into invasive cancer through a series of steps including
low-grade and high-grade dysplasia. Dysplasia means 'abnormal
growth'.
Reversal of the Barrett's oesophagus cannot
treat all symptoms of acid reflux. Treatment of the Barrett's
oesophagus simply minimises the risk of future cancer
development.
