Complications of Liver Biopsy: Benefits and Risks

A liver biopsy is a procedure that involves taking away a tiny portion of liver tissue and investigating it under a microscope for indications of damage or disease. If blood tests or scans indicate that you may have a liver problem, your doctor might suggest a liver biopsy. A liver biopsy is also used to figure out the stage of someone's liver disease. This information supports in making treatment decisions.

Risks of Liver Biopsy

A liver biopsy provides an accurate diagnosis of liver conditions such as fatty liver disease, hepatitis, and cirrhosis. It helps determine the severity of liver damage, assess treatment effectiveness, and guide further medical decisions.While a liver biopsy is a safe procedure when performed by skilled healthcare providers, potential risks include:

Pain: The most common complication, usually mild and temporary.
Bleeding: Rare but may require hospitalization or a blood transfusion if excessive.
Infection: In rare cases, bacteria can enter the bloodstream or abdominal cavity.
Unintentional organ injury: The biopsy needle may accidentally puncture nearby organs, such as the gallbladder or lung.

In a transjugular liver biopsy, a narrow tube is inserted through a neck vein to access the liver. Rare risks include:

Blood accumulation (hematoma): May cause pain and swelling at the catheter site.
Temporary facial nerve problems: Can cause eyelid drooping or eye issues.
Vocal changes: Hoarseness, weak voice, or temporary loss of voice.
Lung puncture (pneumothorax): Accidental puncture may lead to a collapsed lung.

Post-procedure, patients are monitored for a few hours before being discharged. Resting for 24 hours is recommended, along with avoiding strenuous activities for a week. Any severe pain, bleeding, or breathing difficulties should be reported to a doctor immediately.
