Percutaneous liver biopsy

A percutaneous liver biopsy involves the needle aspiration of a core of liver tissue for histologic analysis. It’s done under local or general anesthesia. This biopsy can detect hepatic disorders and can confirm cancer if ultrasonography, computed tomography (CT) scans, and radionuclide studies have proved inconclusive.

In a liver biopsy, a Menghini needle attached to a 5-ml syringe containing normal saline solution is introduced through the chest wall and intercostal space. Negative pressure is created in the syringe. The needle is then pushed rapidly into the liver and pulled out of the body entirely to obtain a tissue specimen.
