Can a liver biopsy harm the human body?

Liver biopsy is a method in which a puncture needle is used to puncture the liver to extract biopsy tissue and then perform histopathological examination. At present, semi-automatic biopsy needles are mostly used. Before the operation, the doctor will use 0.5% lidocaine around the positioning puncture point to perform local anesthesia from the skin to the liver capsule, and the patients generally do not have pain.

Liver biopsy is generally safe for patients with normal coagulation and no hepatic hemangioma.

Liver biopsy is performed under the guidance of color Doppler ultrasound. The location and depth of the puncture can be very accurate, avoiding large blood vessels and causing no bleeding. Fine needle aspiration biopsy only removes 2-3 pieces of liver tissue less than 1 mm thick and 20 mm long, so the damage to the liver is minimal.
