Percutaneous Liver Biopsy Definition
a diagnostic procedure for removing a tissue sample from the LIVER. The doctor typically performs percutaneous liver biopsy on an outpatient basis in a hospital setting. Most people prefer to receive a mild sedative before the procedure. After anesthetizing the abdominal SKIN and tissue above the liver, the doctor makes a tiny incision and inserts a special biopsy needle. The needle withdraws a core of liver tissue, which a laboratory then analyzes to determine the nature and structure of cells and other substances it contains.
Percutaneous liver biopsy helps diagnose numerous conditions affecting the liver, including HEPATITIS, CIRRHOSIS, LIVER FAILURE, STEATOHEPATITIS, and LIVER CANCER. Though minimally invasive, percutaneous liver biopsy exposes the liver to several risks including INFECTION, INFLAMMATION, and bleeding. These complications are uncommon though can be serious.
