Post-hepatectomy liver failure: signs, prevention and care | CION Cancer Clinics
Liver failure after surgery means the liver left behind cannot yet do the whole liver's work. The signs are deepening jaundice, slow clotting, fluid in the belly and new confusion or drowsiness. It is uncommon, and the operation is planned to prevent it. This page explains why it happens, how teams measure the risk beforehand, and which signs at home mean going to hospital today. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
What is liver failure after liver surgery?
Post-hepatectomy liver failure means the part of the liver left behind after an operation cannot yet do the whole liver's work. The signs are yellowing of the eyes that keeps deepening, fluid building up in the belly, blood that clots slowly, and new confusion or drowsiness. It is uncommon, and surgeons plan the whole operation around preventing it.
Why it happens at all
The liver can regrow after part of it is removed. In the first days, though, the remaining piece has to clean the blood, make clotting proteins and clear bile on its own while it is still recovering from the operation. If that piece is too small, or was already scarred by cirrhosis or fatty liver, it can fall behind. This page is about surgery for a cancer that started in the liver, or that spread there. The planning is the same in both.
Why most people never meet it
Before any operation, the team measures how much healthy liver will remain and how well it works. If the answer is not enough, they change the plan rather than take the risk. That calculation is explained on our page on the future liver remnant.
Liver failure after surgery is something the team watches for daily. It is not a sign that the operation went wrong.What to look for
What are the signs of liver failure after surgery?
Most of these are picked up on blood tests in the ward before anyone can see them. Families still notice them first sometimes, so it helps to know them.
Jaundice that keeps rising
A little yellowing is common after liver surgery and fades. What matters is jaundice that deepens day after day instead of settling. The blood test behind it is bilirubin, the yellow waste the liver normally clears.
Slow clotting
The liver makes the proteins that help blood clot. When it is struggling, a blood test called the INR goes up. You may also see oozing from drain sites or bruising that spreads easily.
Fluid in the belly
Called ascites. The belly swells, the drain keeps producing a lot of fluid, or the legs swell. It can also come from other causes after surgery, so it is checked rather than assumed.
Confusion or sleepiness
Called hepatic encephalopathy, meaning the brain is affected by toxins the liver has not cleared. It can look like muddled speech, sleeping through the day or behaving unlike themselves.
Also checked
- Low urine output
- Low blood sugar
- Fever, which can mean infection

After discharge, these mean hospital today
If someone who has had liver surgery becomes confused or unusually drowsy, turns more yellow, has a swelling belly with fever or pain, vomits blood or passes black stools, go to hospital today. Go to the hospital that did the operation if you can, or the nearest emergency department if you cannot. Take the discharge summary with you. Do not wait for the next clinic visit.
Prevention and care
How do surgeons prevent it, and what happens if it starts?
Measuring the liver before surgery
Blood tests, a Child-Pugh assessment of liver function and a CT or MRI scan show how much liver will remain and how healthy it is. The tumour board reviews this before anyone books a date. Our page on how much liver can be removed explains the thinking.
Growing the remnant first, if needed
If the remaining piece would be too small, a procedure called portal vein embolisation can make it grow before the operation. Sometimes a smaller operation, or a different treatment, is chosen instead.
Daily blood tests in the first week
Bilirubin, INR and other markers are checked every day. The trend matters more than any one result. A high reading that is falling is reassuring. A reading that keeps climbing is acted on.
Supportive care while the liver recovers
There is no single drug that switches the liver back on. Care means treating infection quickly, correcting clotting and blood sugar, managing fluid and nutrition, and supporting the kidneys. Many people recover as the liver regrows. Severe cases need intensive care, and in rare cases a transplant team is consulted.

On the ward chart
What do the words on the blood reports mean?
- Bilirubin
- The yellow pigment the liver clears into bile. A rising level after surgery is one of the first signs the remnant is struggling.
- INR
- A measure of how quickly blood clots. A higher number means slower clotting, which can mean the liver is making fewer clotting proteins.
- Albumin
- A protein made by the liver. Low levels can come with swelling and fluid in the belly.
- Future liver remnant
- The share of liver that will be left after the operation. Surgeons calculate it in advance because it predicts the risk of liver failure.
- Grade of liver failure
- Teams grade it by how much treatment it needs: watching only, extra care on the ward, or intensive care. Ask which grade applies if you hear the word.
Commonly believed
What do families often get wrong about it?
"Any yellowing after liver surgery means the liver has failed."
Mild jaundice in the first days is common and usually settles. Doctors look at the direction of the results over several days and at the other signs together, not one reading.
"He needs less protein so the liver is not overloaded."
Cutting protein is an old belief that slows healing. A recovering liver and a healing wound both need good nutrition. Follow the ward dietitian, not advice from relatives.
"A herbal liver tonic will help it regrow faster."
No tonic has been shown to help, and some herbs can damage a liver that is already working hard. Tell the team about anything you plan to give, without fear of being judged.
"If the surgeon removed more tumour, it was a better operation."
The aim is to remove the tumour completely while leaving enough healthy liver to live on. Removing more than is safe is exactly what causes liver failure.
Being straight with you
What can this page not tell you?
It cannot tell you your own risk. That depends on how much liver is being removed, whether there is cirrhosis or fatty liver, earlier treatment, and your general health. Only the surgical team who has seen your scans and blood tests can put those together, so ask them directly what your risk looks like and what they will do to lower it.
Who this mostly does not apply to
People having a small resection from an otherwise healthy liver rarely meet this problem. The risk sits mainly with large resections, cirrhotic livers and people who have had a lot of chemotherapy before surgery. If you are worried about other problems, our page on complications of liver surgery covers bleeding, bile leaks and infection.
How CION fits in
CION's surgical oncologists assess and plan liver operations, and the tumour board reviews each case. Your team will tell you where the operation takes place. Interventional procedures and intensive care are provided through accredited partner hospitals.
Questions we are asked
Common questions about liver failure after surgery
How common is liver failure after liver surgery?
It is uncommon after a planned resection, and rarer still when the remaining liver is large and healthy. The risk is higher after very large resections and in livers with cirrhosis. Your surgeon can tell you how your own situation compares, based on your scans and blood tests.
When does it usually show up?
It usually shows itself in the first several days after surgery, while the patient is still in hospital, which is why blood tests are done daily. Later problems after discharge are more often infection or fluid, but any new confusion or deepening jaundice at home needs hospital the same day.
Can the liver recover from it?
Often, yes. Milder forms usually improve as the remaining liver regrows over the following weeks, with supportive care meanwhile. Severe forms are serious and need intensive care. Your team will be honest with you about which situation you are in and how it is changing.
Is there a medicine that treats it?
No single medicine reverses it. Treatment supports the body while the liver catches up: treating infection, correcting clotting and blood sugar, controlling fluid, feeding well and protecting the kidneys. Medicines like lactulose may be used for confusion. Doses are decided by the ward team only.
Does cirrhosis mean I cannot have surgery at all?
Not always. Some people with well-preserved cirrhosis can have a smaller resection safely. Others are better served by ablation, TACE or transplant. Our page on why a small tumour sometimes cannot be removed explains how teams decide.
Does chemotherapy before surgery raise the risk?
Some chemotherapy drugs can injure healthy liver tissue, especially after many courses. This is mostly an issue for cancer that spread to the liver from the bowel. Surgeons take the number of treatments into account and sometimes allow a gap before operating.
What should the family watch for after discharge?
Watch for confusion or unusual sleepiness, eyes or skin turning more yellow, a swelling belly, fever, vomiting blood or black stools. Any of these means going to hospital today. Keep the discharge summary and the surgical team's contact details where everyone in the house can find them.
Can CION review my surgical plan before I decide?
Yes. A CION surgical oncologist can review your scans and blood reports, and the tumour board can discuss whether resection, a smaller operation or another treatment fits your liver. Call the helpline and a care coordinator will tell you what to bring.
