Liver biopsy is an invasive technique in which a small piece of liver tissue is removed under local anesthesia by puncturing the abdominal wall or through ( Trans jugular venous biopsy) right internal jugular vein. Liver biopsy is useful, but it needs a specialist care setting and expertise so unsuitable for screening a large number of people. The technique is generally safe, but complications may arise in 2% of patients such as intra-abdominal hemorrhage, pneumothorax, hemothorax, biliary peritonitis, or liver injury. Complications if any, usually are evident within 3-4 hours after the biopsy specimen is collected. In some cases, it is necessary to perform a liver biopsy as no imaging modality can distinguish between simple fatty liver or hepatitis or accurately quantify the extent of hepatic fibrosis.
