Complications of liver surgery and what is watched for | CION Cancer Clinics
The main complications after liver surgery are a bile leak, bleeding, infection, fluid in the belly and the remaining liver struggling to cope. Most people have none of these, and most that happen are found early and treated. This page explains what the team checks in hospital, what is normal at home, and the warning signs that mean going to hospital the same day. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
What can go wrong after liver surgery?
The complications the team watches for most closely are a bile leak, bleeding, infection, fluid building up in the belly and, most seriously, the remaining liver struggling to cope. Most people recover without any of these, and most complications that do happen are found early and treated.
Why liver surgery has its own list
The liver makes bile, stores blood and makes the proteins that help blood clot. When part of it is removed, the cut surface can leak bile or ooze blood, and the smaller liver has to do all of its work while it regrows. A liver already scarred by cirrhosis (long-term scarring that hardens the liver) has less reserve, so complications are more likely and are watched for more carefully.
Which surgery this page is about
This page covers liver resection, an operation that removes part of the liver, for cancer that started in the liver or spread to it. The steps of the operation are explained on the liver resection surgery page. Complications after a liver transplant are different and are handled by the transplant centre.
What is watched for
Which complications matter most, and how are they treated?
These are the problems your team is looking for in the days after surgery. Each one has a known way of being found and handled.
Bile leak
Bile can seep from the cut surface of the liver. It often shows as greenish fluid in the surgical drain. Many leaks settle with the drain left in place a little longer. Some need a small procedure to place a tube or a stent. See bile leak after liver surgery for detail.
Bleeding
Bleeding is most likely in the first day or so. It shows as a falling blood count, a fast pulse or blood in the drain. It may need a transfusion, and occasionally a return to theatre.
Liver failure after surgery
The remaining liver may not cope while it regrows. Signs include yellowing of the skin, fluid in the belly, confusion and poor clotting on blood tests. This is the complication surgeons work hardest to prevent. Liver failure after surgery has its own page.
The others
These are common after any major abdominal operation and are checked for routinely.
- A collection of fluid or infection near the liver
- Fluid in the belly, called ascites
- Chest infection from shallow breathing
- Blood clots in the legs or lungs
- Wound infection
Not sure whether this applies to you?
Ask an oncologistWhile you are in hospital
How does the team check for problems after the operation?
Close watching at first
Pulse, blood pressure, breathing and urine output are checked often. Many people spend the first night in a high-dependency or intensive care area. This is routine and is not a sign that something is wrong.
Daily blood tests
Bilirubin (the yellow pigment the liver clears), INR (how well the blood clots) and the blood count show how the remaining liver is coping and whether there is bleeding.
Watching the drain
If a drain was placed, nurses note how much fluid comes out and what it looks like. A change in colour can be the first sign of a leak.
Getting you moving
Sitting up, deep breathing and short walks start early. They lower the risk of chest infection and blood clots.
A scan if something changes
A fever, new pain or a change in the blood tests usually leads to an ultrasound or CT scan to look for a collection or leak.

After you go home: when to go to hospital today
Go to hospital today, and contact your surgical team on the way, if you have a fever or shivering, pain that is getting worse instead of better, yellowing of the skin or eyes, a belly that is quickly getting bigger, new confusion or unusual drowsiness, vomiting blood or black stools, breathlessness or chest pain, or a swollen, painful leg. Do not wait for your next appointment.

Side by side
Is what I am feeling normal recovery or a warning sign?
Usually part of recovery
Tell the team today
Wound pain that eases a little each day
Pain that is getting worse, or new pain in the shoulder or belly
Deep tiredness for some weeks
Drowsiness or confusion that family notice
A poor appetite at first
Vomiting that does not stop, or being unable to drink
A small amount of clear fluid from the wound
Pus, redness that spreads, or green fluid from the wound
Mild swelling of the ankles
A belly swelling quickly, or one painful swollen leg
Commonly believed
What do families often misunderstand about complications?
"A complication means the surgeon made a mistake."
Complications happen even when an operation is done well, because the liver is soft, full of blood vessels and bile ducts, and often already scarred. What matters is that they are found early and handled properly.
"A bile leak means another big operation."
Most bile leaks settle with the drain left in a little longer, or with a tube placed under scan guidance. A second open operation is needed only occasionally.
"Once he is home, the risk is over."
Some problems, such as a collection, a clot or an infection, can appear after discharge. That is why the warning signs above matter and why the first follow-up visit should not be skipped.
"We should not bother the doctors unless it is serious."
Surgical teams would rather hear about a small worry early than a big one late. Calling about a fever or a change in the wound is the right thing to do.
Being straight with you
What this page cannot tell you
It cannot tell you your own risk of a complication. That depends on how much liver is being removed, how healthy the remaining liver is, whether you have cirrhosis or portal hypertension (raised pressure in the main vein into the liver), and your general health. Your surgeon is the right person to explain your risk before you agree to the operation.
Who this does not apply to
If you have had ablation, TACE or radiation rather than an operation, the side effects are different and are covered on those pages. If you have had a liver transplant, your transplant team manages your recovery. Bile duct operations that also remove part of the bowel or bile ducts carry extra risks that are not covered here.
Who to ask
Ask the surgical team before the operation which complications are most likely for you and who to call after discharge. CION's surgical oncologists assess and plan liver operations, and your team will tell you where the operation takes place.
Keep the discharge summary and the team's contact details with you after surgery, so any hospital you go to can see what was done.Questions we are asked
Common questions about complications after liver surgery
How common are complications after liver surgery?
Minor complications, such as a wound infection or a small fluid collection, are fairly common and usually easy to treat. Serious complications are less common. The risk is higher with a larger operation and with cirrhosis. Your surgeon can explain your likely risk based on your scans and blood tests.
How will I know if I have a bile leak?
In hospital, a bile leak usually shows as green or brown fluid in the drain. At home, it can cause fever, pain under the right ribs, a swollen belly or green fluid from the wound. Any of these needs a call to your surgical team the same day.
What is liver failure after surgery?
It means the part of the liver left behind cannot do all its work while it regrows. Signs include jaundice, fluid in the belly, confusion and poor clotting. It is the main reason surgeons measure the remaining liver carefully before operating, and it is treated in hospital with close support.
Why is my skin slightly yellow after the operation?
Mild yellowing can happen for a short time as the remaining liver adjusts. The team watches bilirubin on blood tests to see whether it is settling. If the yellowing appears or deepens after you are home, contact the team that day.
Does cirrhosis make complications more likely?
Yes. A scarred liver has less reserve, bleeds more easily and regrows more slowly. Fluid in the belly and liver failure are more likely. This is one reason surgery is offered more cautiously in cirrhosis, and why other treatments are often weighed first.
Can complications delay further cancer treatment?
Sometimes. If you need treatment after surgery, it usually waits until the wound and liver have recovered. A complication can push that back. Your oncologist will plan around it and explain whether the delay matters for you.
What should the family watch for at home?
Fever or shivering, worsening pain, yellow skin or eyes, a swelling belly, new confusion or sleepiness, vomiting blood, black stools, breathlessness or a swollen leg. Families often notice confusion before the patient does. Any of these means going to hospital today.
Can CION help if I had surgery elsewhere and something feels wrong?
For anything on the warning list, go to the nearest hospital today. For questions about your recovery or what comes next, a CION oncologist can review your discharge summary, scans and pathology report with you. One helpline serves every CION centre.
