Nerve blocks and other procedures for liver cancer pain | CION Cancer Clinics
A nerve block, most often a coeliac plexus block, can reduce deep abdominal pain from liver cancer and lower the amount of morphine needed. It helps some people a great deal and others very little, because liver pain travels along more than one set of nerves. This page explains the procedures, what happens, who they do not suit and the warning signs afterwards. At CION Cancer Clinics, our team supports patients and families through symptoms, follow-up and life during and after treatment.

The short answer
Can a nerve block help liver cancer pain?
Sometimes. A coeliac plexus block, an injection that numbs or switches off the bundle of nerves carrying pain from the upper abdomen, can reduce deep abdominal pain and the amount of morphine a person needs. It tends to help less with pain from the liver itself than with pain from the pancreas, so it is one option among several and never a sure thing.
Why liver pain is different
Much liver cancer pain comes from the tumour stretching the thin outer covering of the liver, called the capsule. That pain travels partly along other nerves, including those that run to the right shoulder. A coeliac block does not reach all of them, which is why results vary from person to person. Where liver cancer pain comes from explains this in more detail.
Who the page is for
It applies whether the cancer started in the liver or spread there from another organ. It is most relevant when pain is still hard to control despite regular painkillers, or when those painkillers cause too much drowsiness or constipation.
A nerve block is added to good pain medicine. It rarely replaces it entirely.The procedures
Which procedures are used for liver cancer pain?
The pain team chooses based on where the pain is, what is causing it and how fit the person is for a procedure.
Coeliac plexus block
A needle is guided by a scan or an endoscope to the nerve bundle deep in the upper abdomen. A local anaesthetic numbs it for a while. Adding alcohol or a similar agent can switch the nerves off for longer. This is called neurolysis.
Splanchnic nerve block
A close relative of the coeliac block that targets the nerves a little higher up, near the spine. Some pain specialists prefer it when a large tumour or swollen glands make the usual route hard to reach.
Blocks for rib and side pain
When pain sits along the lower ribs or the right side, numbing the nerves that run under the ribs, or a block placed near the spine, can help.
Often considered when
- Pain is sharp and in one place
- The tumour has reached the rib cage
- Breathing in makes the pain worse
Treating the cause instead
A short course of palliative radiation to a painful tumour, draining tense fluid from the abdomen, or a procedure such as TACE can ease pain by shrinking or relieving what causes it.
Not sure whether this applies to you?
Ask an oncologistHow it usually goes
What happens if a coeliac plexus block is planned?
A review of pain and scans
The oncologist and pain specialist look at where the pain is and at recent scans, to check the nerve area can be reached safely.
Blood tests for bleeding
Liver disease affects clotting, so the INR and platelet count are checked. Blood thinners may need to be paused, but only on a doctor's advice.
The procedure
It is done under sedation, guided by CT or by an endoscope passed through the mouth. Many people go home the same day or the next.
Watching the effect
Painkillers are reduced slowly over the following days if pain settles. Stopping them all at once can cause withdrawal and rebound pain.
!
After a block, go to hospital today if you see this
Mild dizziness when standing and loose stools for a few days are common after a coeliac block. Go to the nearest emergency department today if there is new weakness or numbness in the legs, fainting, severe new pain in the abdomen or back, fever, or vomiting blood. Tell the staff the person has liver disease and had a nerve block, and bring the discharge papers.
Side by side
How does a nerve block compare with stronger tablets?
Nerve block
Increasing the painkillers
A single procedure, sometimes repeated
Daily medicine, adjusted over time

Possible for almost everyone
Can reduce drowsiness and constipation by cutting the opioid needed
Drowsiness and constipation rise with the dose
Works better for deep, central pain
Works for most kinds of pain to some degree
Effect can fade as the illness changes
Dose can be changed within days

Commonly believed
What families often think about nerve blocks, and what is true
"A nerve block will take the pain away completely."
Some people get large relief, others get a little, and a few get none. Most still need some painkiller afterwards, usually at a lower dose. Going in with honest expectations avoids disappointment.
"It is only for the last few days of life."
Blocks often work better when done earlier, while the person is fit enough for the procedure and before the tumour has grown around the nerves. Asking about it early is reasonable.
"Cutting a nerve will leave him paralysed."
The coeliac nerves carry pain and gut signals, not movement. Weakness in the legs is a rare complication and is one of the warning signs to act on, not an expected result.
"If the block works, the cancer must be shrinking."
A block changes the pain signal, not the tumour. Pain relief after a block says nothing about whether the cancer has changed. Scans and the treating team answer that question.
Being straight with you
Who a nerve block does not suit, and what this page cannot tell you
A block is usually not suitable when clotting is badly affected and cannot be corrected, when there is a large amount of fluid in the abdomen, when there is an active infection, or when the person is too unwell to lie still for the procedure. It also suits pain that sits mainly in the right shoulder or along the skin less well.
The evidence is thinner than for pancreatic cancer
Most research on coeliac blocks comes from pancreatic cancer. For liver cancer the studies are smaller, so specialists rely partly on experience. Ask how often the procedure has helped people with pain like yours.
Where it happens and who decides
Nerve blocks are done by pain specialists or interventional radiologists. CION's medical oncologists and supportive care team assess the pain, continue the painkiller plan, and coordinate the block through accredited partner hospitals. Your team will tell you where it takes place. This page cannot say whether a block suits you. That needs someone who has examined you and seen your scans and blood tests.
Questions we are asked
Common questions about nerve blocks for liver pain
Is a coeliac plexus block painful?
It is done with sedation and local anaesthetic, so most people feel pressure and some discomfort rather than sharp pain. Some have a short flare of aching in the back or abdomen afterwards, which settles. Tell the team how the procedure felt so the painkiller plan can be adjusted.
How long does the relief last?
It varies widely. A block with local anaesthetic alone wears off fairly soon. One that switches the nerves off can last much longer, though pain may return as the tumour changes. The specialist can say what to expect for the type of block planned.
Can the block be repeated?
Often, yes, if it helped the first time and the person is still well enough. A repeat usually works less well than the first. If it did not help at all, repeating the same block is rarely worthwhile, and other options are discussed instead.
Why is he having diarrhoea after the block?
The coeliac nerves also slow the gut. When they are switched off, the bowel can move faster for a while. It usually settles on its own. Drink plenty of fluids and call the team if it is severe, bloody or comes with dizziness or fever.
Is it safe with cirrhosis and a low platelet count?
It depends on how low the count is and whether clotting can be improved before the procedure. Fluid in the abdomen and enlarged veins also add risk. The specialist weighs these against the likely benefit. Read more about bleeding risk in liver disease.
Should we try radiation or a block first?
It depends on the cause. If one tumour is stretching the liver's covering, radiation aimed at it may help more. If pain is deep and central from tumour or glands near the nerves, a block may suit better. The tumour board can look at the scans and advise.
Does it affect cancer treatment?
Usually not. Most people can continue or start immunotherapy, targeted therapy or other treatment after a short recovery. The oncologist will plan the timing so that the procedure and treatment do not clash.
How do we ask about a nerve block?
Tell the treating oncologist that pain is not controlled or that painkillers cause too much drowsiness. Bring the latest scans and blood reports. You can also call the CION helpline, and a review with the medical oncology and supportive care team can be arranged.
