Barrett’s oesophagus
In Barrett’s oesophagus, the lining at the lower end of the food pipe has changed after years of acid reflux. It causes no symptoms of its own. It matters because, in a small number of people, it can slowly progress to cancer of the food pipe. Regular endoscopy finds early changes at a stage when they can be removed through the endoscope.
At a glance
What it is
The normal lining of the lower food pipe is replaced by a lining that resembles the intestine.
Common signs
None of its own. Most people have long-standing heartburn or acid reflux; some have no symptoms at all.
How it is confirmed
Endoscopy shows the changed lining, and biopsies confirm it and look for precancerous change (dysplasia).
How it is treated
Reflux control with an acid-blocker, endoscopy at planned intervals, and removal of the lining through the endoscope if dysplasia appears.
What are the signs of Barrett’s oesophagus?
What you may notice
- Nothing from Barrett’s itself
- Heartburn or sour fluid coming up, often for many years
- In some people, reflux symptoms that have faded with time, because the changed lining is less sensitive to acid
Who is more likely to have it
- Reflux symptoms for five years or more, or every week
- Men, and people over 50
- Tobacco use
- Weight carried around the waist
- A parent, brother or sister with Barrett’s oesophagus or cancer of the food pipe
See a doctor promptly if you have
- Food sticking when you swallow, or pain on swallowing
- Weight loss you cannot explain
- Vomiting blood, or black, tarry stools
- A low blood count (anaemia)
These are not signs of Barrett’s itself. They are reasons for an early endoscopy in anyone, and more so in someone known to have Barrett’s.
What it is
What is happening inside?
The food pipe is lined by flat, skin-like cells. They are not built to withstand acid. When stomach acid and bile wash up into the lower food pipe for years, that lining can be replaced by a different kind, similar to the lining of the intestine. The new lining stands up to acid better. This is why symptoms sometimes ease.
The concern is that these changed cells can, over many years and in a small number of people, pass through stages called low-grade and high-grade dysplasia and then become cancer. Barrett’s oesophagus is the only known forerunner of this type of cancer, called adenocarcinoma. For a person with Barrett’s and no dysplasia, the chance of cancer in any one year is small: well under one in a hundred. Most people with Barrett’s never develop cancer.
Barrett’s is less common in India than in Western countries. I do see it, mostly in men with long-standing reflux.
Who should be checked for Barrett’s?
Not everyone with acidity needs an endoscopy to look for Barrett’s. A single screening endoscopy is suggested for a person who has long-standing reflux symptoms and three or more of the risk factors listed above.
Anyone with warning signs needs an endoscopy for that reason alone. See upper GI endoscopy.
How I find out
Which test answers which question?
Upper GI endoscopy with biopsies
It tells us: Whether the lining has changed, and how long the changed segment is. Biopsies taken at set intervals along the segment show whether there is dysplasia.
When I use it: To make the diagnosis, and then at planned intervals for follow-up.
A second opinion on the biopsy
It tells us: Whether dysplasia is truly present. Reflux inflammation can look like dysplasia under the microscope.
When I use it: Whenever a biopsy reports dysplasia. A second pathologist with a special interest in the gut reviews the slides before treatment is planned.
Repeat endoscopy after healing
It tells us: What the lining looks like once inflammation has settled.
When I use it: When the first endoscopy shows active inflammation from reflux, after a course of acid-blocker.
Treatment
How is Barrett’s oesophagus treated?
Control the reflux
- An acid-blocker taken every day, long term. In Barrett’s this is advised even when symptoms are mild
- The same food and timing changes that help reflux: smaller evening meals, a gap of three hours before lying down, raising the head end of the bed, and weight loss around the waist
- Stopping tobacco
Endoscopy at planned intervals
When biopsies show no dysplasia:
- A changed segment shorter than 3 cm: endoscopy every five years
- A segment 3 cm or longer: endoscopy every three years
The interval is set by the biopsy result, not by how you feel.
If dysplasia is found
After a second pathologist confirms it, the changed lining is removed through the endoscope. Any raised area is lifted off first. The remaining lining is then treated with heat so that normal lining grows back. This is day-care treatment over a few sessions. It is done at centres that perform it regularly, and I arrange it there. Follow-up endoscopy continues afterwards.
When surgery is the right answer
Anti-reflux surgery is an option for reflux that medicines do not control or for a large hiatus hernia. It is not done to prevent cancer in Barrett’s, because it has not been shown to do that. Removal of the food pipe is now needed only when cancer has grown deeper than the endoscope can treat.
Root-cause care
The integrative view: what else I look at
The plan above is the treatment. Alongside it, I look at what keeps reflux going:
- Weight around the waist: it pushes stomach contents upward and is a risk factor for Barrett’s in its own right. A dietitian in my practice works on this with you.
- Evening habits: late, large dinners and lying down soon after eating.
- Tobacco and alcohol: both worsen reflux, and tobacco raises the cancer risk.
- Long-term acid-blocker use: in Barrett’s the benefit is clear, so the medicine continues. I review vitamin B12 and magnesium in people who have taken it for years. See long-term acid-blockers.
No food, supplement or herbal preparation has been shown to make Barrett’s go away or to lower the cancer risk. I do not suggest any for that purpose.
Recovery
What should I expect?
| When | What happens |
|---|---|
| At diagnosis | Endoscopy with biopsies. An acid-blocker is started or continued. |
| 8 to 12 weeks | Repeat endoscopy if the first one showed inflammation, to check the biopsies again once it has healed. |
| Every 3 to 5 years | Follow-up endoscopy with biopsies, for as long as you are fit enough to benefit from treatment. |
| If dysplasia appears | Second opinion on the biopsy, then removal of the lining through the endoscope, and closer follow-up. |
Questions patients ask me about Barrett’s oesophagus
Does Barrett’s oesophagus mean I will get cancer?
No. Most people with Barrett’s never develop cancer. The risk in any one year is small. Follow-up endoscopy exists to find the few who are progressing, at a stage when treatment through the endoscope works well.
Can Barrett’s go away?
The changed lining does not usually return to normal with medicines or diet. An acid-blocker controls reflux and may lower the chance of progression, but it does not remove the changed lining. When dysplasia develops, the lining can be removed through the endoscope and normal lining grows back.
I have had acidity for years. Do I need an endoscopy?
If you have warning signs, yes, soon. If not, a screening endoscopy is suggested when long-standing reflux comes with three or more risk factors: being male, age over 50, tobacco use, weight around the waist, and a close relative with Barrett’s or food pipe cancer.
Why must I take an acid-blocker if I have no heartburn?
In Barrett’s, the changed lining feels acid less, so the absence of symptoms does not mean the absence of reflux. Daily acid-blocker treatment is advised to protect the lining.
Is there a test without an endoscopy?
A swallowed capsule on a string, which collects cells from the food pipe as it is pulled back, is accepted as a screening option in recent guidelines. It is not yet widely available in India. Endoscopy with biopsy remains the standard test.
Should my family be checked?
Barrett’s and food pipe cancer run in some families. A close relative with long-standing reflux should mention your diagnosis to their doctor, because it counts as a risk factor when deciding on an endoscopy.
