Endoscopic resection for early oesophageal cancer | CION Cancer Clinics
Early cancer or abnormal cells in the lining of the food pipe, including in Barrett's oesophagus, can often be removed through a scope by EMR or ESD. That avoids removing the food pipe, one of the largest operations in cancer surgery. This page explains the Barrett's pathway, how the two cancer types differ, who scope treatment does not suit, and what comes afterwards. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Can early oesophageal cancer be treated through a scope?
Often, yes, if it is found very early. A raised area of abnormal cells or early cancer in the food pipe lining, including one arising in Barrett's oesophagus, can usually be removed by EMR or ESD through a scope passed down the mouth. The food pipe stays in place, which avoids one of the largest operations in cancer surgery.
What Barrett's oesophagus has to do with it
Barrett's oesophagus is a change in the lining at the lower end of the food pipe, caused by long-term acid reflux. It is not cancer. In a small number of people it slowly develops abnormal cells, called dysplasia, and then early cancer. Regular scopes aim to catch that change while it can still be removed without an operation.
Why removing the food pipe is avoided if possible
Removing the food pipe, called oesophagectomy, is a major operation with a long recovery and lasting changes to eating. When a cancer is confined to the lining, the chance of spread to lymph glands is low, and a scope removal followed by close follow-up may be offered instead.
What makes it different in India
Barrett's-related cancer is less common here than in Western countries. The more common type is squamous cell cancer, which grows in the middle of the food pipe and is found early far less often.
The pathway
What usually happens from a Barrett's diagnosis to treatment?
-
Barrett's is found on a scope
Often during a scope for long-standing heartburn. Biopsies are taken from several levels. Acid-lowering tablets are usually started or continued.
-
Regular check scopes
If no abnormal cells are seen, the team plans check scopes at intervals. Their purpose is to find any change early.
-
Abnormal cells or a raised area
If biopsies show high-grade dysplasia, or a raised area appears, a second pathologist often confirms the finding. Any raised area is usually removed with EMR, so the laboratory can examine it whole.
-
Treating the remaining Barrett's
The flat Barrett's lining left behind can still turn abnormal. It is often treated with ablation, which uses heat or cold to destroy the abnormal lining so normal lining grows back.
-
Long-term follow-up
Check scopes continue for years, along with acid-lowering tablets, to catch any return early.
Not sure whether this applies to you?
Ask an oncologistTwo kinds of cancer
Does the type of oesophageal cancer change the approach?
Yes. The two main types start in different cells, in different parts of the food pipe, for different reasons.
Adenocarcinoma
Grows at the lower end, near the stomach, usually from Barrett's lining. Linked to long-term reflux and excess weight. Early raised areas are often removed by EMR, followed by ablation of the remaining Barrett's.
Usual scope approach
- EMR of the raised area
- Ablation of flat Barrett's
Squamous cell cancer
Grows in the flat lining cells, most often in the middle of the food pipe. Strongly linked to tobacco, alcohol and very hot drinks. It is the more common type in India. When found early, ESD is often used to remove it in one piece.
Usual scope approach
- ESD for one-piece removal
- Iodine dye spray to map the edges
Side by side
How do EMR, ESD and ablation differ in the food pipe?
What it is
Used for
EMR: growth lifted and snared off
Raised areas in Barrett's, smaller early growths
ESD: growth cut free underneath in one piece
Early squamous cancers, larger growths
Ablation: abnormal lining destroyed by heat or cold
Flat Barrett's with abnormal cells, after any raised area is removed
Oesophagectomy: the food pipe is removed by an operation
Cancer that has gone deeper or reached lymph glands

Commonly believed
What do people often believe about Barrett's and early cancer?
"Barrett's means I have cancer."
Barrett's is a change in the lining, not cancer. Most people with it never develop cancer. Check scopes exist to catch the few changes that do happen, early enough to treat through a scope.
"Now the heartburn has stopped, I can skip the check scope."
Acid-lowering tablets relieve symptoms but do not remove Barrett's. Abnormal cells cause no symptoms of their own. The scope is the only way to find them.
"Trouble swallowing is just acidity."
Food sticking in the chest, especially if it is getting worse, needs a scope soon. By the time a cancer causes trouble swallowing, it is usually past the stage a scope can remove.
"After EMR, the Barrett's is gone."
EMR removes the raised area only. The rest of the Barrett's lining stays and is usually treated with ablation, then watched with check scopes.
On your report
What do the words on the report mean?
- Intestinal metaplasia
- The lining change that defines Barrett's. It is not cancer.
- Low-grade dysplasia
- Mildly abnormal cells. Often confirmed by a second pathologist, then watched closely or treated.
- High-grade dysplasia
- Markedly abnormal cells, one step before cancer. Usually treated through a scope.
- Nodule
- A raised area seen on the scope. It is usually removed by EMR so it can be examined whole.
- Stricture
- A narrowing of the food pipe. It can follow a wide removal and is usually stretched through a scope.
Being straight with you
Who is it not suitable for, and what can this page not tell you?
Scope treatment is not suitable for a food pipe cancer that has grown deep into the wall, spread to lymph glands, or already causes trouble swallowing or weight loss. Those cancers are usually treated with chemotherapy, radiotherapy, an operation or a combination.
The narrowing that can follow
When a large part of the food pipe's circumference is removed, the healing scar can narrow it. You may notice food sticking again weeks later. Tell your team, because it is usually treated by stretching the narrowing through a scope, sometimes more than once.
When general health changes the picture
For someone frail or with serious heart or lung disease, removing the food pipe carries more risk. A team may then weigh scope treatment differently. That is a judgement for the treating team with the patient and family.
What this page cannot tell you
It cannot tell you whether your growth can be removed, which technique you need, or how often you will need scopes. Those depend on your biopsies, scope pictures and scans, reviewed by your treating team.

Common questions about early oesophageal cancer and EMR
Will I be able to swallow normally after EMR?
Most people return to normal eating once the raw area heals, starting with liquids and soft food. After a wide removal, a narrowing can form while it heals. If food starts sticking again, tell your team. It is usually treated by stretching through a scope.
Do I still need acid-lowering tablets afterwards?
Usually, yes. They help the raw area heal and reduce the acid damage that caused Barrett's in the first place. Your doctor will tell you which tablet to take and for how long. Do not stop taking it on your own, even when you feel well.
What is ablation, and does it hurt?
Ablation destroys the flat Barrett's lining with heat or cold through a scope, so normal lining grows back. It is done under sedation. Afterwards, chest discomfort and pain on swallowing for a few days are common. Your team will give medicines to ease this.
I have squamous cell cancer. Is EMR used for that too?
For early squamous cell cancer, ESD is more often used, so the growth comes out in one piece for the laboratory. Whether your cancer is early enough depends on its depth and whether glands look involved. Many squamous cancers in India are found later, when an operation or other treatment is needed.
My father smokes and drinks. Should he have a scope?
If he has trouble swallowing, food sticking, weight loss or a hoarse voice, he should see a doctor soon. Tobacco and alcohol raise the risk of cancers in the mouth, throat and food pipe. Whether a scope is needed without symptoms is a question for his doctor.
What happens if the report shows deeper cancer?
If the laboratory finds the cancer went deeper than expected, or is inside tiny vessels, the team will discuss further treatment. That may be an operation, chemotherapy, radiotherapy or a combination. Your general health and wishes are part of that discussion.
How often will I need scopes afterwards?
Check scopes usually start a few months after treatment and continue for years, with gaps that lengthen if all is well. The schedule depends on what was found and whether ablation was needed. Missed scopes are the main way a return goes unnoticed.
Is EMR for Barrett's covered by Aarogyasri or insurance?
Coverage depends on the scheme and the diagnosis on your biopsy report. Aarogyasri, CGHS, ECHS and EHS may apply, and many cashless insurers cover scope procedures. Call the helpline with your reports and card details so your cover can be checked before you plan the date.
