Biopsy - biliary tract

Cytology analysis - biliary tract; Biliary tract biopsy

A biliary tract biopsy is the removal of small amounts of cells and fluids from the duodenum, bile ducts, pancreas, or pancreatic duct. The sample is examined under a microscope.

How the Test is Performed

A sample for a biliary tract biopsy can be obtained in different ways.

A needle biopsy can be done if you have a well-defined tumor.

  • The biopsy site is cleaned.
  • A thin needle is inserted into the area to be tested, and a sample of cells and fluid are removed.
  • The needle is then removed.
  • Pressure is put on the area to stop any bleeding. The site will be covered with a bandage.

If you have a narrowing or blockage of the bile or pancreatic ducts, a sample can be taken during procedures such as:

How to Prepare for the Test

You may not be able to eat or drink 8 to 12 hours or more before the test. Your health care provider will tell you ahead of time what you need to do.

Make sure you have someone to drive you home.

How the Test will Feel

How the test will feel depends on the type of procedure used to remove the biopsy sample. With a needle biopsy, you may feel a sting as the needle is inserted. Some people feel a cramping or pinching feeling during the procedure.

Medicines that stop pain and help you relax are commonly used for other biliary tract biopsy methods.

Why the Test is Performed

A biliary tract biopsy can determine if a tumor started in the liver or spread from another location. It also can determine if the tumor is cancerous.

This test may be done:

  • After a physical exam, x-ray, MRI, CT scan, or ultrasound shows abnormal growths in your biliary tract
  • To test for diseases or infection

Normal Results

A normal result means there are no signs of cancer, disease, or infection in the biopsy sample.

What Abnormal Results Mean

Abnormal results may be due to:

Risks

Risks depend on how the biopsy sample was taken.

Risks may include:

  • Bleeding at the biopsy site
  • Infection

  • Gallbladder endoscopy

    Gallbladder endoscopy - illustration

    An endoscope, a flexible fiberoptic scope with a light, is inserted through the mouth into the duodenum. A catheter is advanced through the endoscope and inserted into the pancreatic or biliary ducts. A contrast agent is injected into these ducts and X-rays are taken to evaluate their caliber, length and course. Endoscopic retrograde cholangiopancreatography (ERCP) is performed to identify any narrowing, stones, or tumors in the pancreatic or biliary ducts.

  • Bile culture

    Bile culture - illustration

    A bile culture test is performed to see if there is infection in the biliary tract. A specimen of bile is placed in culture media and observed for growth of microorganisms. If there is no growth in the culture, then there is no infection. If there is growth in the culture media, the growth is then isolated and identified to determine the appropriate method of treatment.
