Procedure
Liver biopsy is considered minor surgery, so it is done at the hospital. For the biopsy, you will lie on a hospital bed on your back with your right hand above your head. After marking the outline of your liver and injecting a local anesthetic to numb the area, the physician will make a small incision in your right side near your rib cage, then insert the biopsy needle and retrieve a sample of liver tissue. In some cases, the physician may use an ultrasound image of the liver to help guide the needle to a specific spot.
You will need to hold very still so that the physician does not nick the lung or gallbladder, which are close to the liver. The physician will ask you to hold your breath for 5 to 10 seconds while he or she puts the needle in your liver. You may feel pressure and a dull pain. The entire procedure takes about 20 minutes.
Two other methods of liver biopsy are also available. For a laparoscopic biopsy, the physician inserts a special tube called a laparoscope through an incision in the abdomen. The laparoscope sends images of the liver to a monitor. The physician watches the monitor and uses instruments in the laparoscope to remove tissue samples from one or more parts of the liver. Physicians use this type of biopsy when they need tissue samples from specific parts of the liver.
Transvenous biopsy involves inserting a tube called a catheter into a vein in the neck and guiding it to the liver. The physician puts a biopsy needle into the catheter and then into the liver. Physicians use this procedure when patients have blood-clotting problems or fluid in the abdomen.
Recovery
After the biopsy, the physician will put a bandage over the incision and have you lie on your right side, pressed against a towel, for 1 to 2 hours. The nurse will monitor your vital signs and level of pain.
You will need to arrange for someone to take you home from the hospital since you will not be allowed to drive after having the sedative. You must go directly home and remain in bed (except to use the bathroom) for 8 to 12 hours, depending on your physician's instructions. Also, avoid exertion for the next week so that the incision and liver can heal. You can expect a little soreness at the incision site and possibly some pain in your right shoulder. This pain is caused by irritation of the diaphragm muscle (the pain usually radiates to the shoulder) and should disappear within a few hours or days. Your physician may recommend that you take Tylenol for pain, but you must not take aspirin or ibuprofen for the first week after surgery. These medicines decrease blood clotting, which is crucial for healing.
Like any surgery, liver biopsy does have some risks, such as puncture of the lung or gallbladder, infection, bleeding, and pain, but these complications are rare.
