Before your biopsy:
If local anesthesia is used, then only the area that is being operated on is numbed. It is given as an injection and may also be given with a sedative.
There are different techniques used to do a liver biopsy, including:
You will lie on your back with your right hand behind your head. An
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.
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.
A tiny flexible tube will be threaded into a vein in your neck or groin. This tube will be threaded all the way into the veins in your liver. A biopsy needle will be passed through the tube to get a biopsy sample.
You will lie on your right side for at least 2 hours.
About 15-20 minutes
You will have mild pain or cramping at the biopsy site. You may also have pain in the right shoulder. The pain should last for less than 30 minutes.

The biopsy results will take 1-4 weeks. You and your doctor will discuss the results.
