Key points
- There are three main types — intrahepatic (inside the liver), hilar or Klatskin (where the ducts join below the liver) and distal (near the pancreas) — and each needs a different operation.
- Painless jaundice with itching, pale stools and dark urine is the commonest first sign of hilar and distal tumours.
- Only a minority of patients are suitable for surgery when first diagnosed; a specialist HPB review of good-quality scans decides this.
- Hilar tumours usually need a liver resection with bile duct excision; distal tumours need a Whipple operation.
- Chemotherapy is usually recommended after surgery and is the main treatment when the cancer cannot be removed.
Where the cancer starts changes everything
| Type | Location | How it usually shows up | Main operation |
|---|---|---|---|
| Intrahepatic | Small bile ducts inside the liver | A mass on a scan, vague pain, weight loss; jaundice is late | Liver resection (hepatectomy) |
| Hilar (Klatskin tumour) | Where the right and left hepatic ducts meet, just below the liver | Painless jaundice, itching, pale stools | Extended liver resection with removal of the bile duct and lymph nodes |
| Distal | Lower bile duct, running behind the pancreas | Painless jaundice, sometimes a palpable gallbladder | Whipple operation (pancreaticoduodenectomy) |
Hilar tumours are the commonest type. They sit next to the main blood vessels of the liver — the portal vein and hepatic artery — which is why deciding whether they can be removed takes careful study of the scans.
Symptoms and who is at risk
- Yellow eyes and skin that deepens steadily, usually without pain — see jaundice in adults.
- Intense itching, pale or clay-coloured stools and dark tea-coloured urine.
- Loss of appetite and weight; tiredness.
- Fever with shivering if the blocked bile becomes infected (cholangitis).
Most patients have no identifiable risk factor. Known associations include primary sclerosing cholangitis, choledochal cysts, long-standing bile duct stones, liver fluke infection (important in parts of South-East Asia) and chronic liver disease from hepatitis B or C.
The scans that decide whether surgery is possible
- 1
Triple-phase contrast CT of the abdomen and chest
Shows the tumour, its relation to the portal vein and hepatic artery, lymph nodes, and any spread to the liver, lungs or lining of the abdomen.
- 2
MRI with MRCP
Maps how far the cancer runs up the bile ducts into the liver. For hilar tumours this determines which side of the liver can be kept.
- 3
Blood tests
Liver function, clotting and CA 19-9. CA 19-9 supports the diagnosis but is raised by jaundice alone, so it is interpreted after drainage.
- 4
PET-CT or staging laparoscopy in selected cases
Used to look for small deposits of spread that CT can miss, before committing to a major operation.
Scans before stents
Where possible, the imaging should be done before a stent is placed in the bile duct. Stents cause inflammation that blurs the tumour's edges on CT and MRI, making it harder to judge how far it extends.
A tissue diagnosis is not always required before surgery. Biopsies of bile duct tumours are often inconclusive, and when the scans strongly suggest a resectable cancer, waiting for repeated biopsies can cost valuable time.
Can the tumour be removed?
A tumour is resectable when the surgeon can remove it with clear margins and leave behind enough healthy liver, with its own blood supply and bile drainage, for the patient to recover. Surgery is usually not recommended when the cancer has spread to distant organs or distant lymph nodes, when it has grown into the blood vessels of both halves of the liver, or when it extends too far into the ducts on both sides.
Borderline decisions are common with hilar tumours. This is where review by an HPB surgeon experienced in major liver surgery, alongside radiologists and oncologists, matters most — a tumour called inoperable in one assessment is sometimes removable with a more extensive liver resection and vessel reconstruction.
Getting ready for a major liver operation
Pre-operative biliary drainage
A jaundiced liver recovers less well after resection. When a large part of the liver is to be removed, the part that will remain is usually drained first — by ERCP stent or a tube placed through the skin (PTBD) — until bilirubin falls. Cholangitis is treated before surgery.
Portal vein embolisation (PVE)
If the liver that will remain is too small, a radiologist blocks the portal vein branch to the side being removed. Over several weeks the other side grows, making the operation safer. See liver resection for how the future liver remnant is measured.
Nutrition and fitness
Correcting weight loss, controlling diabetes, walking daily and stopping smoking and alcohol all improve recovery from a long operation.
The operations
For a hilar cholangiocarcinoma, the standard operation removes the bile duct where the tumour sits, the right or left half of the liver (often including the caudate lobe, which lies against the tumour), the gallbladder and the surrounding lymph nodes. The remaining bile ducts are then joined to a loop of small intestine (a Roux-en-Y hepaticojejunostomy). Sometimes a segment of portal vein must be removed and rejoined.
For a distal cholangiocarcinoma, the operation is a Whipple procedure, because the lower bile duct runs through the head of the pancreas. For an intrahepatic tumour, a liver resection with lymph node removal is performed, sized to the tumour.
These are long operations, typically followed by a period in intensive care and a hospital stay of around two weeks, longer if complications occur. Complications after hilar resection are more frequent than after most abdominal operations and include bile leak, infection and post-hepatectomy liver failure; the risks for an individual patient are discussed in detail before consent.
Chemotherapy and honest expectations
After surgery, chemotherapy is commonly advised to lower the chance of recurrence. When the cancer cannot be removed, chemotherapy (often combined with immunotherapy) and stenting to relieve jaundice are the main treatments; they control the disease and symptoms for a period but are not curative. Radiotherapy has a role in selected cases.
Outcomes depend heavily on the stage, the margins achieved and whether lymph nodes are involved. Published series from large centres report that roughly a quarter to a third or more of patients who have a complete resection are alive at five years, with better figures for small, node-negative tumours. Recurrence is common, which is why follow-up scans continue for several years.
Liver transplantation is used for a very small, carefully selected group with early unresectable hilar cancer under specific protocols at some centres worldwide; it is not a routine option and is discussed only when strict criteria are met.

Frequently asked questions
Is bile duct cancer curable?
It can be cured when it is found early enough to be removed completely with clear margins, though recurrence is still possible. When it cannot be removed, treatment aims to control the disease and relieve symptoms rather than cure it.
What is a Klatskin tumour?
A Klatskin tumour is a hilar cholangiocarcinoma — a bile duct cancer at the point where the right and left bile ducts join, just below the liver. It usually needs removal of part of the liver along with the bile duct.
Should a stent be put in before seeing the surgeon?
If the patient is stable, it is better for the surgeon to review the CT and MRI first. A stent is sometimes needed urgently for cholangitis, but where there is time, planning the drainage around the intended operation avoids problems later.
How long is the hospital stay after cholangiocarcinoma surgery?
Usually around two weeks for a major liver and bile duct resection, including a few days in intensive care. Full recovery to normal activity generally takes two to three months.
Why is my CA 19-9 so high?
CA 19-9 rises in bile duct cancer but also rises with any blocked bile duct or infection. It should be interpreted after the jaundice has been relieved, and a normal value does not rule out cancer.
Can a liver transplant treat bile duct cancer?
Only in a very small, highly selected group with early hilar cancer that cannot be removed, under strict protocols. For most patients, resection or chemotherapy is the appropriate treatment.
