Open surgery for the liver: when it is the right choice | CION Cancer Clinics
Open liver surgery is usually chosen when a tumour is large, deep or close to major blood vessels, or when a big part of the liver must be removed. It is not a second-best option. This page explains why a surgeon chooses an open operation over keyhole surgery, how the choice is made, and who should not have liver surgery at all. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
When is open liver surgery the right choice?
Open surgery is usually chosen when the tumour is large, sits close to the main blood vessels, or needs a big piece of liver taken out. It is also chosen when the surgeon needs to feel the liver directly or control bleeding quickly. Being offered open surgery does not mean you were given a lesser option.
What open surgery means
The surgeon reaches the liver through one longer cut across the upper abdomen, instead of through several small keyhole cuts. The aim inside is the same: remove the part of the liver holding the cancer and leave enough healthy liver behind. This is called a liver resection.
Which cancer this page is about
This page is mainly about cancer that started in the liver, hepatocellular carcinoma (HCC), and bile duct cancer inside the liver. If the cancer spread to the liver from the bowel, the planning is different. Read about surgery for colorectal liver metastases instead.
The choice between open and keyhole is made after the choice to operate at all. It is the second decision, not the first.What tips the decision
Why would my surgeon choose an open operation?
Surgeons look at the tumour, the liver around it and you. Any one of these can make the open route the safer one.
The tumour
A large tumour, or several tumours spread across the liver, is often easier to remove safely with an open view.
- Close to the main veins or the portal vein
- Deep in the back of the liver
- Growing into a nearby organ or the diaphragm
The size of the operation
Removing a whole half of the liver or more, rebuilding a bile duct, or repairing a blood vessel usually needs the room an open cut gives. It also lets the surgeon stop bleeding quickly if it starts.
The liver itself
A liver scarred by cirrhosis is firmer and bleeds more easily. Some surgeons prefer the direct hand control of open surgery here, though keyhole surgery can suit a small tumour in a well-working liver.
Your history
Earlier operations leave scar tissue inside the abdomen. A repeat resection after the cancer has come back is often done open for this reason.
Open is not old-fashioned. It is the right tool for certain jobs.Not sure whether this applies to you?
Ask an oncologistHow the choice is made
Who decides between open and keyhole surgery, and how?
Scans that map the liver
A triple-phase CT or MRI shows where each tumour sits and how close it is to the blood vessels. CION arranges these scans through diagnostic partners.
A check of liver function
Blood tests such as bilirubin, albumin and INR, and sometimes a Child-Pugh score, show how well the liver works. Read more on who is suitable for liver surgery.
The tumour board
Surgeons, oncologists and radiologists review the scans together. They first ask whether surgery is the right treatment, then which approach is safest.
A conversation with you
Your surgeon explains the plan and why. Your team will tell you where the operation takes place. Sometimes a keyhole operation is changed to open partway through, and you should agree to that possibility in advance.
Side by side
How does open surgery compare with keyhole surgery?
Open surgery
Keyhole (laparoscopic or robotic)
One longer cut under the ribs
Several small cuts and a camera
Suits large, deep or multiple tumours
Suits smaller tumours near the liver surface
Surgeon can feel the liver directly
Surgeon works through instruments and a screen
More wound pain and a slower start to walking
Usually less pain and a shorter stay
Aims to remove the whole tumour with a healthy rim
The same goal, and the same standard of removal

Who this does not suit
When is no kind of liver surgery the right answer?
Open surgery is a way of doing a liver resection. It does not make surgery possible for someone who is not suitable for resection in the first place. A bigger cut does not make up for a weak liver.
When the liver cannot spare a piece
With advanced cirrhosis, high pressure in the portal vein, fluid in the abdomen (ascites) or swollen veins in the food pipe (varices), the liver left behind may fail after surgery. This is why a small tumour sometimes still cannot be removed. Our page on why a small tumour sometimes cannot be removed explains this in full.
What may be offered instead
Depending on the tumour and the liver, the team may suggest ablation, TACE, radiation, a liver transplant or tablets and infusions. CION coordinates ablation, TACE and radiation through accredited partner hospitals. Transplant happens only at licensed transplant centres.
If you have been told surgery is not possible, a second opinion is reasonable. It may confirm the advice, and that is useful too.Being straight with you
What this page cannot tell you
It cannot tell you whether your own operation should be open or keyhole. That depends on details only visible on your scans and blood tests, and on the experience of the surgeon looking at them. Two surgeons can reasonably prefer different approaches for the same tumour.
It cannot predict your recovery
How long you stay in hospital and how quickly you return to work depend on the size of the operation, the state of your liver and your general health. Ask your surgeon for an honest estimate for you, and plan for a family member to stay close by during the first part of recovery, especially if you are travelling from a district.
It does not explain the operation step by step
For how the operation itself is done, see what a liver resection involves. Bring your scan reports and blood tests to the consultation. Questions written down beforehand get better answers.
Questions we are asked
Common questions about open liver surgery
Is open surgery worse than keyhole surgery for the cancer?
No. Both aim to remove the tumour completely with a rim of healthy liver around it. What matters most for the cancer is whether it is fully removed. Keyhole surgery mainly helps with recovery, and only when the tumour suits it.
How big is the cut in open liver surgery?
The cut usually runs under the right ribs and sometimes across to the left or up the middle. Its size depends on how much liver is being removed. Your surgeon can show you where it will be before the day, so the scar is not a surprise.
Can a keyhole operation turn into an open one?
Yes. If bleeding, scar tissue or the position of the tumour makes keyhole surgery unsafe, the surgeon will switch to open during the operation. This is a safety decision, not a failure. You will be asked to agree to it beforehand.
Is open surgery more painful?
It usually hurts more in the first days because the wound is longer. Pain is controlled with an epidural, a pain pump or regular medicines. Getting up and walking early, with help, is part of recovery and is easier when pain is well controlled.
Can I have open surgery if I have cirrhosis?
Some people with mild, well-compensated cirrhosis can have a liver resection, open or keyhole. People with ascites, jaundice or significant portal hypertension usually cannot. Your liver function, not the type of cut, decides whether surgery is safe.
Will I need a blood transfusion?
Many people do not, but the team prepares for it before any liver operation. Larger open operations and livers with cirrhosis carry more risk of bleeding. See our page on blood loss and transfusion for what is done to reduce it.
How long will I stay in hospital?
Usually longer than after keyhole surgery, and longer again after a large resection. The exact stay depends on how your liver recovers. Your surgeon will give you an expected range for your own operation, and our page on hospital stay explains what affects it.
Can CION help me decide?
Yes. CION's surgical oncologists assess and plan liver operations, and the tumour board reviews your scans. Bring your CT or MRI and recent blood tests. Call the helpline if you would like a consultation or a second opinion on a plan you have already been given.
