Anastomotic leak after esophagectomy, explained | CION Cancer Clinics
An anastomotic leak means the new join between the stomach tube and the remaining food pipe has not sealed, and fluid is escaping into the chest or neck. It usually shows in the first week as a fever and a fast pulse. Most leaks are treated by resting the join, antibiotics and a drain; some need a stent placed from inside; a few need another operation. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is an anastomotic leak after esophagectomy?
An anastomotic leak means the new join between the stomach tube and the remaining food pipe has not sealed fully, and saliva or swallowed fluid is escaping through the gap. Anastomosis is the surgeon's word for that join. It is the complication the team watches for hardest in the first week, because fluid leaking inside the chest or neck causes infection.
Why this join is harder than most
The stomach has been shaped into a tube and pulled a long way up. Its blood supply now comes from one artery instead of several, and the top of the tube, where the join is made, is the part with the least blood. Tissue with poor blood flow heals slowly. Add the strain of a long operation and the effects of chemoradiation given before it, and the join is more fragile than a join in the bowel would be.
What a leak is not
It is not a sign that the surgeon made a mistake, and it is not the cancer coming back. Leaks happen in every unit in the world that does this operation. What differs between units is how quickly a leak is picked up and how well it is managed once found.
A small leak found early is often managed without another operation. That is why the fever and pulse checks in the first week are so frequent.

Signs that need the team the same day
A new fever, a racing or irregular heartbeat, new chest or upper back pain, breathlessness, or cloudy, foul-smelling fluid from a neck wound or a chest drain. On the ward, call the nurse at once. At home, go to the nearest emergency department and say you have had a food pipe operation. Do not wait to see if it settles overnight.
Not sure whether this applies to you?
Ask an oncologistFinding it
How does the team find out whether the join has leaked?
Suspicion
Usually a fever, a fast pulse and a rise in the infection markers on a blood test, most often between the third and seventh day. A change in what comes out of a drain is another early clue.
A contrast swallow or CT scan
You swallow a liquid that shows on X-ray, or the scan is done with contrast. If the liquid tracks outside the join, the leak is confirmed. Many units do this test as routine before starting you on sips.
A look from inside
A thin camera passed down the throat lets the surgeon see the join directly, judge how large the gap is and check whether the stomach tube itself is healthy. Small leaks can sometimes be treated at the same sitting.
Grading
Leaks are graded by what they need. Some need only antibiotics and time. Some need a drain or an internal stent. A few need another operation. The grade decides the plan, not the word "leak" on its own.
Treating it
What happens once a leak is confirmed?
Treatment is matched to the size of the leak and how unwell you are. It often escalates step by step.
Rest the join
Nothing by mouth, so nothing passes through the gap. Feeding continues through the tube into the small bowel, which is one reason that tube is placed at the operation. Antibiotics are started.
Drain the collection
Fluid that has gathered in the chest or neck is drained, either through the drain already in place, a new drain placed under scan guidance, or by opening a neck wound to let it out.
Seal it from inside
Through the camera, a covered stent can be placed across the gap, or a small sponge with suction can be laid into it. The gap closes over weeks while feeding carries on through the tube.
Ask your centre
- Which of these they use
- Who does them, and when
Return to theatre
Needed when the stomach tube itself has lost its blood supply, or when infection cannot be controlled any other way. The join may be taken down and rebuilt later. This is the least common path.

One field. No form to fill in, and no charge for the call.
Side by side
A join in the neck and a join in the chest, compared
Join in the neck
Join in the chest
Neck join: leaks are somewhat more common
Chest join: leaks are somewhat less common
Neck join: a leak usually drains out through the neck wound
Chest join: a leak drains into the chest, which is more serious
Neck join: more often managed by opening the wound and time
Chest join: more often needs a drain, a stent or surgery
Neck join: hoarse voice is more likely
Chest join: hoarse voice is less likely
Being straight with you
Why do leaks happen, and what lowers the chance?
Most leaks come down to blood supply and tension. If the top of the stomach tube has too little blood flow, or the join is pulled tight, it does not heal. Smoking, diabetes, poor nutrition before surgery and a low protein level all make healing slower. Radiotherapy given to the area beforehand does too, although for most people its benefit against the cancer outweighs that.
What you can change and what you cannot
You cannot change where the join sits or how the tube is made. You can stop smoking, get protein and weight up with the dietitian before surgery, and keep diabetes well controlled. After the operation, doing the breathing exercises and walking early lowers chest infection, which in turn puts less strain on the healing join.
What this page cannot tell you
It cannot tell you your own chance of a leak, or whether a leak that has already happened will settle without surgery. Published leak rates vary widely between units and depend on how a leak is defined. Ask your centre for its own recent leak rate, how it usually manages a leak, and whether the people who do the camera treatments are on site.
If a leak has been found, ask the team which grade it is and what the next step is if the first plan does not work.Commonly believed
Four things families say about a leak, and what is actually true
"A leak means the surgery has failed."
It means one part of the recovery has hit a problem. The cancer has still been removed. Most leaks heal, and most people who have one go on to eat normally, although the stay in hospital is longer and the road is harder.
"He is not eating, so he must be starving."
The feeding tube into the small bowel gives full nutrition while the join rests. Nothing by mouth is the treatment, not a sign of neglect. Bringing food in from home and slipping him a sip can reopen a leak that was closing.
"If they had used keyhole surgery, this would not have happened."
The join is made the same way whichever route the surgeon uses to reach it. Keyhole and open operations have similar leak rates. Blood supply, tension and healing decide it, not the size of the cut.
"Once he is home, the leak risk is over."
Most leaks show in the first week, but a late leak can appear after discharge, sometimes as a fever with pain on swallowing. That is why the red flags on this page matter for several weeks, not only on the ward.
Questions we are asked
Common questions about anastomotic leak
How common is a leak after this operation?
Common enough that every unit plans for it, and uncommon enough that most people never have one. Reported rates differ a great deal between centres and between neck and chest joins. Ask your centre for its own recent figure and how it defines a leak, because definitions differ too.
When does a leak usually show up?
Most often in the first week, typically from the third day onwards, as a fever, a fast pulse or a change in the drain fluid. Some appear later, after you have started eating. A few are found only on the routine swallow test, with no symptoms at all.
Will he need another operation?
Usually not. Many leaks are managed by resting the join, antibiotics and a drain, and more are now treated from inside with a stent or a suction sponge through the camera. Another operation is kept for leaks that cannot be controlled those ways, or when the stomach tube itself is not healthy.
How long will the hospital stay be if there is a leak?
Longer, sometimes by weeks. The join has to be rested until a repeat swallow test shows it has sealed, and feeding through the tube continues meanwhile. Nobody can give you a date at the start. Ask the team what they are waiting to see before the next step.
Can he go home with the feeding tube while the leak heals?
Sometimes, once the infection is controlled and the family has been taught to use the tube. The dietitian sets the feed plan and the team arranges reviews. This is decided case by case, and a leak that is still collecting fluid is not one to manage at home.
Does a leak affect whether the cancer comes back?
The leak is a healing problem, not a cancer problem. Removing the cancer and the lymph nodes was done at the operation and is not undone by a leak. What a leak can do is delay any chemotherapy planned afterwards, which the oncologist will weigh once recovery is back on track.
Will there be a narrowing at the join afterwards?
A join that has leaked is more likely to scar and narrow as it heals, so trouble swallowing solids in the months afterwards is worth reporting early. It is usually treated by stretching the join through the camera, a short procedure that can be repeated if needed.
What should we ask the surgeon before the operation?
Ask where the join will be made and why, what the unit's recent leak rate is, how a leak would be managed and by whom, and whether the camera treatments are available on site. A surgeon used to this operation will welcome these questions rather than avoid them.
