You may not be able to eat or drink 8-12 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.
