Liver Biopsy 肝切片檢查(英文)
A liver biopsy is a procedure to remove a small piece of liver tissue by using a biopsy needle, and the pathologist can examine this tissue by using a microscope and check if there are any signs of damage or disease. Apart from the anesthesia period, the time for the biopsy takes only about 5 seconds, but the tumor biopsy must spend for more than 30 seconds. The patient will also need to lie on his or her right side to compress the puncture wound with sandbag after the procedure to prevent internal bleeding. The patient who will undergo a tumor biopsy must be admitted because he or she has a relatively high risk of bleeding after this examination.
