Ultrasound-guided liver biopsy and drainage
Despite the presence of non-invasive alternatives, liver biopsy remains the indispensable standard for the diagnosis of many liver diseases, and also provides information for prognostic evaluation and clinical therapeutic decision. Ultrasound guidance has become standard practice for percutaneous liver biopsy and also other percutaneous biliary interventions. Ultrasound offers a number of advantages including its real-timed guidance, lack of radiation exposure, inexpensiveness and the ability to perform at the bedside. In this review, I discuss the indications, contraindications, equipment and procedure, possible complications and post-procedural care for the ultrasound-guided hepatic procedures including percutaneous liver biopsy, percutaneous transhepatic biliary drainage, percutaneous cholecystostomy, percutaneous catheter drainage and needle aspiration.
