Percutaneous Liver Biopsy
Read this information so you understand the procedure and its risks. Please ask questions about anything that you do not understand.
What is a percutaneous liver biopsy?
The term “percutaneous” means “to go through the skin.” During a percutaneous liver biopsy, a doctor places a needle through the skin of the right upper abdomen into the liver and takes small pieces of tissue to send to a laboratory for analysis.
In most cases we use this procedure to determine why a child has increased liver enzymes. Causes include hepatitis or biliary atresia, which is the underdevelopment of the bile ducts leading to the small intestine.
How is a percutaneous liver biopsy performed?
Using ultrasound for guidance, the doctor inserts the needle into the liver to obtain small pieces of tissue. Then the doctor inserts a substance called Gelfoam® into the liver to minimize bleeding into the tract (where the needle went into the liver). The body absorbs the substance, which is harmless. We will put a bandage over the site of the injection.
Will my child be awake during the procedure?
No. The procedure will be performed with IV sedation or general anesthesia.
Learn more about sedation and general anesthesia.
Will my child be in any pain?
Your child may have some discomfort around the biopsy site for several days that can be treated with over-the-counter pain medication.
How long does the procedure take?
Approximately one hour.
What risks are associated with this procedure?
This procedure is considered low-risk. However, potential complications include:
- bleeding
- infection
- puncture of the lung (pneumothorax or hemothorax)
- puncture of the gallbladder with subsequent bile leak
What happens after the procedure?
Your child may experience some discomfort and will need to lie in bed for four to six hours in the recovery area. You can be with your child during this time.
After four hours, we will take a blood count (a CBC) to tell us whether there is bleeding from the liver into the abdominal cavity. Most children don’t experience bleeding. Outpatients whose blood counts are normal will be able to go home.
When can I remove the bandage?
Leave the bandage on for 48 hours. Then you may remove the gauze and clear bandage; do not remove the Steri-Strips® (white strips). If the Steri-Strips haven’t fallen off after seven days, you may remove them.
When can my child bathe?
Keep the site dry for 48 hours. After 48 hours, your child may shower or have a sponge bath, but must keep the area dry. If showering, your child must face away from the showerhead. Do not submerge the site in water (bath or pool) until the Steri-Strips have fallen off.
Are there any activity restrictions?
Your child should rest after the procedure. The next day, your child may return to light activities, but must avoid strenuous activity or contact sports, including rough playing, for one week.
