The complications associated with a liver biopsy are usually minor; most will occur in the first two hours following the procedure, and greater than 95% in the first 24 hours. The most significant risk is prolonged internal bleeding. Other complications...
from percutaneous liver biopsies include the leakage of bile or the introduction of air into the chest cavity (pneumothorax). There is also a small chance that an infection may occur. The risk that an internal organ such as the lung, gallbladder, or kidney might be punctured is decreased when using the ultrasound- or CT-guided procedure.

Definition
A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. Liver biopsies are sometimes called percutaneous liver biopsies, because the tissue sample is obtained by going through the patient's skin.
Purpose
A liver biopsy is usually done to diagnose a tumor, or to evaluate the extent of damage that has occurred to the liver because of chronic disease. Biopsies are often performed to identify abnormalities in liver tissues after imaging studies have failed to yield clear results.
