What should you know about extrahepatic cholangiocarcinoma?

Doctors may assess jaundice, dark urine, pale stools, itching, abdominal discomfort, or unexplained weight loss, although symptoms vary. Blood tests can show changes in bile flow, while ultrasound, CT, or MRI can map the ducts and nearby structures. A biopsy may help confirm the tumour type. The location, size, spread, and general health all influence the plan.

A specialist team may first relieve blocked bile flow with a drain or stent if this is needed. If the tumour can be removed, an operation may involve taking out the affected duct and nearby tissue; see Tumour Removal Surgery for an overview. When surgery is not suitable or cannot remove all disease, treatment may include Chemotherapy or Targeted Therapy, depending on tumour findings. Ask how tissue testing affects the options.

Contact a clinician promptly for yellowing of the eyes or skin, worsening itching with dark urine, pale stools, fever, chills, or increasing abdominal pain. A blocked bile duct can become infected, particularly when fever and chills occur together. Seek urgent help for confusion, severe weakness, fainting, or difficulty keeping fluids down.

Which part of the extrahepatic duct is involved? Has imaging shown spread or a blocked drainage pathway? Is surgery technically possible, and what would it involve? Should the tumour be tested for changes that could guide targeted treatment? How will jaundice, itching, nutrition, and pain be managed?
