Cholangiocarcinoma of the biliary tract

The biliary tract carries bile from the liver toward the small intestine and includes bile ducts inside and outside the liver, together with the gallbladder. Cholangiocarcinoma starts in a bile duct. Doctors describe it as intrahepatic when it begins within the liver, perihilar when it is at the main duct junction, or distal when it starts farther down the extrahepatic duct.

Tumour location influences how disease presents. Cancers narrowing a major duct can present with jaundice, dark urine, pale stools and itching. A tumour within the liver may first cause upper abdominal discomfort, tiredness, reduced appetite or weight loss. These symptoms are not specific to cancer and require clinical evaluation.

Evaluation commonly brings together imaging of the liver, bile ducts and other body areas, blood tests, and tissue examination when appropriate. Specialists define the starting site, extent, relationship to blood vessels, effect on bile drainage and liver function. This information helps determine whether tumour removal can be considered.

Other care may include chemotherapy, treatment directed at a suitable molecular tumour change, radiotherapy, or procedures that restore bile flow. Support for itching, pain, digestion and nutrition can be provided alongside cancer treatment. Bring medication details and symptom changes to appointments so the plan can account for day-to-day needs.

Arrange timely medical assessment for new yellowing of the eyes or skin, dark urine or pale stools. Fever, chills and increasing abdominal pain with jaundice need urgent care because blocked bile can become infected. Emergency help is appropriate for collapse, confusion, severe breathlessness, uncontrolled bleeding, or vomiting that prevents hydration.

Ask where in the biliary tract the cancer began and what stage or extent the scans show. Discuss whether bile flow is blocked, whether surgery is technically possible, what tissue and molecular testing found, the intended goal of each treatment, and which symptoms should trigger an urgent call.
