Biopsy of the biliary tract

Alternative names:

gallbladder biopsy; pancreatic biopsy

What the risks are:

There is some risk of bleeding from the biopsy site. With the needle biopsy, there is a slight chance of infection at the puncture site. Also see the risks for an ERCP if the biopsy is taken through an endoscope.

Special considerations:

This test is performed after a health history, physical examination, or other tests and procedures have indicated abnormal growths or signs of malignancy or disease.
