Barrett's Oesophagus

What is Barrett’s Oesophagus?

Barrett’s Oesophagus is a long-term complication due to chronic inflammation in a small proportion of people (10%) with GORD. 


Barrett’s Oesophagus is characterised by tissue resembling the intestinal lining replacing the usually present esophageal tissue.


Impact of Barrett’s Oesophagus on Anatomy and Health

Barrett’s oesophagus can increase the risk of developing esophageal cancer, so diagnosing and treating reflux early is crucial.


Risk Factors for Barrett’s Oesophagus Affect?

Barrett’s Oesophagus is nearly two-three times more common in men than women. 


The mean age of affected older people is an age of 55 or above. It is rarely found in children.


The criteria for people who should be screened for Barrett’s Oesophagus include the following:

  • white men over the age of 50, 
  • with a history of smoking, and
  • a family history of either Barrett’s Oesophagus or esophageal cancer. 


Causes of Barrett’s Oesophagus

Barrett’s oesophagus is caused by long-term exposure to acid reflux, leading to changes in the cells lining the oesophagus. The exact cause of this condition is not known. Still, it is believed that chronic inflammation caused by acid reflux can damage the esophageal lining, leading to the development of abnormal cells.


How Does Barrett’s Oesophagus Occur?

GORD is associated with gastric acid and stomach contents washing back into the oesophagus.


The acid damages the esophageal lining and triggers tissue changes resulting in Barrett’s oesophagus. 


Symptoms of Barrett’s Oesophagus

Barrett’s Oesophagus itself usually does not cause specific symptoms. Most symptoms experienced by patients are related to underlying gastro-oesophageal reflux disease.


Common symptoms include:

  • Persistent heartburn
  • Acid regurgitation (acid coming back into the throat)
  • Chest discomfort or burning sensation
  • Difficulty swallowing (dysphagia)
  • Chronic cough
  • Hoarseness or sore throat


In some cases, Barrett’s Oesophagus is discovered incidentally during an endoscopy performed for reflux symptoms.


Preventing Barrett’s Oesophagus

Preventing Barrett’s Oesophagus mainly involves controlling acid reflux early and effectively.


Helpful prevention strategies include:

  • Managing reflux symptoms promptly with medical advice and treatment.
  • Maintaining a healthy weight to reduce abdominal pressure.
  • Avoiding smoking and excessive alcohol consumption.
  • Reducing foods that trigger reflux, such as fatty foods, caffeine, chocolate, and spicy meals.
  • Eating smaller meals and avoiding late-night eating.
  • Elevating the head of the bed to reduce nighttime reflux.
  • Seeking medical evaluation for persistent heartburn lasting longer than several weeks.


Early management of reflux can significantly reduce long-term oesophageal damage.


Stages of Barrett’s Oesophagus

Barrett’s oesophagus is classified according to the degree of change in the esophageal tissue. This includes:

  • No dysplasia – Tissue change is present, but there are precancerous transformations.
  • Low-grade dysplasia – Tissue change is present, with a few signs of precancerous changes
  • High-grade dysplasia – The tissue transformation exhibits many pre-cancerous changes, and esophageal cancer will likely occur next.


Diagnosis of Barrett’s Oesophagus

Barrett’s oesophagus is diagnosed through an endoscopy, where a gastroenterologist examines the oesophagus with a tiny camera attached to a flexible tube. During the endoscopy, a biopsy may be taken to determine if abnormal cells are present.


Treatment for Barrett’s Oesophagus

Your gastroenterologist decides the best approach on a case-by-case basis and the severity of the symptoms. 


The treatment plan always includes medication to control stomach acid and treatment of GORD. 


Lifestyle changes such as 

  • cessation of smoking, 
  • exercise and 
  • removing food responsible for heartburn, such as coffee or chocolate, also controls GORD.


In the case of:

  • No dysplasia – GORD is treated, and routine endoscopy is scheduled to monitor the condition of the oesophagus.
  • Low-grade dysplasia – Your doctor will treat GORD and may recommend removing damaged esophageal cells by endoscopic resection or radiofrequency ablation. He will also recommend a follow-up endoscopy after a few months.
  • High-grade dysplasia – The chances of esophageal cancer are very high at this stage. Your doctor will treat GORD and perform an endoscopic resection of the damaged cells or radiofrequency ablation. In extreme cases, surgery may be needed to remove the damaged segment of the oesophagus.


What If Barrett’s Oesophagus Is Untreated?

If Barrett's oesophagus is left untreated, the abnormal cells in the oesophagus may continue to change and develop into cancerous cells, leading to esophageal cancer. This severe condition can be life-threatening if not diagnosed and treated early. Therefore, diagnosing and treating Barrett's oesophagus as soon as possible is crucial to prevent cancer development.
