Liver Biopsy

Liver biopsy — diagnosis through a small tissue sample taken from the liver with a fine needle under ultrasound guidance.

Diagnostic procedure in which a small liver tissue sample is taken under ultrasound guidance for definitive diagnosis of liver disease, fibrosis staging and treatment planning.

Indication

  • Unexplained chronic elevation of liver enzymes
  • Chronic viral hepatitis (B or C) — fibrosis staging
  • Autoimmune liver diseases such as autoimmune hepatitis and primary biliary cholangitis
  • Determination of fibrosis grade in fatty liver disease (NAFLD/NASH)
  • Diagnosis of a mass or focal lesion in the liver
  • Rejection assessment after liver transplantation
  • Confirmation of metabolic disorders such as Wilson disease and hemochromatosis

Preparation

  • No food or drink for 6-8 hours before the procedure
  • Blood thinners (aspirin, warfarin, clopidogrel) are stopped 5-7 days in advance with physician guidance
  • Coagulation tests (INR, aPTT, platelet count) are performed; platelet or fresh plasma support is provided if needed
  • An IV line is placed; preparation is made for analgesia and mild sedation
  • Informed consent is obtained; transport home with a companion is planned

How it's performed

  1. The patient is placed supine with the right arm raised over the head
  2. A suitable entry point is identified with ultrasound and the skin is sterilized
  3. Local anesthetic is applied to the skin and subcutaneous tissue
  4. While the patient holds an exhaled breath, a fine (tru-cut) needle is used to obtain a small tissue sample
  5. Usually 1-2 samples are taken; if needed, samples may also be obtained from different areas
  6. A pressure dressing is placed on the entry site and the patient is positioned on the right side

Post-procedure

  • The patient stays under hospital observation for 4-6 hours after the procedure; bleeding and blood pressure are monitored
  • Heavy lifting, exercise and blood thinners such as aspirin are avoided for the first 24 hours
  • Mild right shoulder or flank pain may be felt on the first day and is controlled with simple analgesics
  • The pathology result is usually available within 7-10 days and treatment is planned accordingly
  • If severe pain, weakness or fever develops, the hospital should be contacted immediately

Risks

  • Mild to moderate temporary right upper abdominal or shoulder pain (most common, 20-30%)
  • Small bleeding or hematoma at the entry site
  • Significant bleeding (may require blood transfusion, less than 1%)
  • Bile leakage or cholangitis (rare)
  • Pneumothorax, lung injury (very rare)
  • Anesthesia/sedation reaction

FAQ

Will I feel pain during the procedure?

Local anesthesia numbs the skin and subcutaneous tissue, and with sedation the patient is comfortable. A brief sensation of pressure may occur at the time of needle insertion; right shoulder or flank pain afterwards usually resolves within 24 hours.

Can I be discharged on the same day?

Yes. After 4-6 hours of observation and provided there is no complication, same-day discharge is possible; however, you should remain with a companion for the first 24 hours.

When are the results available?

The pathology report is generally ready within 7-10 working days. If special staining is required, this period may extend to 2-3 weeks.

Are there alternatives to biopsy?

For liver fibrosis, non-invasive tests such as Fibroscan or MR elastography may be used; however, biopsy remains the reference standard in the diagnosis of autoimmune, metabolic and focal diseases.
