A liver biopsy is a medical procedure that removes a small sample of liver tissue for laboratory examination to diagnose, stage (e.g., fibrosis/cirrhosis), and monitor liver diseases. Common methods include percutaneous (needle through the skin), transvenous (via the neck vein), or surgical techniques, usually performed under local anesthesia and ultrasound guidance.
Key Information About Liver Biopsy
- Why It’s Done: Used to diagnose hepatitis, cirrhosis, cancer, fatty liver disease, and to evaluate unexplained liver abnormalities found in blood tests or imaging.
- Procedure Types:
- Percutaneous (Most Common): A thin needle is inserted through the right upper abdomen.
- Transvenous (Transjugular): A catheter is threaded through the jugular vein in the neck to the liver, ideal for patients with bleeding risks.
- Laparoscopic/Surgical: Done during surgery to obtain larger, targeted samples.
- Preparation: Patients usually need to fast for 8–12 hours before the procedure and may need to stop taking blood-thinning medications.
- Recovery and Risks:
- Recovery: Patients are monitored for 1–4 hours afterward and must avoid strenuous activity for 48 hours.
- Risks: Generally safe, though complications can include pain at the site (or right shoulder), bleeding, or infection.
- Results: Tissue is examined under a microscope for damage, infection, or cancer, with results usually available in 7–10 days.
This procedure remains a “gold standard” for assessing liver tissue, helping doctors make informed treatment decisions.
