There are different techniques used to do a liver biopsy, including:
Conventional Liver Biopsy
You will lie on your back with your right hand behind your head. An ultrasound or CT scan may be used to help guide the placement of the needle. The skin will be cleaned. Next, medication will be injected to numb the area. A small incision will be made. You will need to exhale and hold your breath while the needle is inserted. Sometimes, the needle will need to be inserted several times. After the procedure, the area will be bandaged.
Laparoscopic Liver Biopsy
Your doctor will make a tiny incision. A long tool with a camera on the end will be passed into your abdomen in the area of the liver. It will send images of the liver to a TV screen. Additional incisions will be made to pass other tools. These tools will be used to remove samples of the liver.
