What is a Liver Biopsy?
A liver biopsy is a minimally invasive diagnostic procedure used to assess liver diseases by removing a small tissue sample for examination. This procedure helps in diagnosing liver conditions, monitoring disease progression, and evaluating treatment effectiveness. The biopsy is typically performed using a thin needle inserted through the skin into the liver, guided by imaging techniques.

When is a Liver Biopsy Recommended?

  • Unexplained liver abnormalities seen in blood tests or imaging scans

  • Chronic liver diseases such as hepatitis B, hepatitis C, or fatty liver disease

  • Cirrhosis or fibrosis assessment to determine liver damage severity

  • Liver tumors or abnormal growths needing further evaluation

  • Monitoring response to treatment in liver conditions

  • Unexplained jaundice or liver dysfunction

How is a Liver Biopsy Performed?

  1. Preparation:

    • The patient may need to stop certain medications (like blood thinners) before the procedure.

    • Blood tests are performed to check clotting ability.

    • Fasting for 6–8 hours is required before the procedure.

  2. Needle Insertion Under Imaging Guidance:

    • The patient lies on their back, and the skin over the liver is cleaned and numbed with local anesthesia.

    • Using ultrasound or CT scan guidance, a thin needle is inserted through the skin into the liver to extract a small tissue sample.

  3. Completion & Recovery:

    • The procedure takes about 15–30 minutes.

    • The patient is monitored for a few hours to ensure there is no bleeding or complications.

    • Light activity is advised for 24 hours, and strenuous activities should be avoided for a few days.

Benefits of a Liver Biopsy

  • Accurately diagnoses liver diseases that may not be detected with blood tests or imaging

  • Minimally invasive with a quick recovery

  • Provides detailed information about liver inflammation, fibrosis, or cancer

  • Helps in monitoring treatment response for chronic liver conditions
