Liver Biopsy: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
A liver biopsy is a medical procedure used to obtain a small sample of liver tissue for diagnostic purposes. It is used to assess liver health, diagnose liver diseases and conditions, and monitor disease progression.
Preparation
Patients may need to do the following before undergoing a liver biopsy:
-
Provide detailed information about past medical history, current medications, and underlying health conditions, such as bleeding disorders.
-
The patient should undergo blood tests to assess liver function, blood clotting ability, and overall health before the procedure. These tests help identify any potential risks or complications.
-
Follow your healthcare provider's fasting instructions, which usually require abstaining from food and drink for several hours before the procedure.
Procedure
A liver biopsy typically involves the following steps:
-
In some cases, conscious sedation or general anesthesia may be used to help the patient relax or sleep during the biopsy.
-
Obtaining a small sample of liver tissue involves inserting a thin biopsy needle through the skin and into the liver. A needle can be inserted either directly into the liver (percutaneous biopsy) or through an incision in the abdomen (laparoscopic biopsy).
-
Once the biopsy needle is in position, a small sample of liver tissue is collected and sent to a laboratory for microscopic examination and analysis.
Recovery
Patients can expect the following recovery process after a liver biopsy:
-
Following the procedure, patients are typically observed for a few hours to check for any immediate complications, such as bleeding or infection.
-
A patient may experience mild discomfort or pain at the biopsy site, which can be alleviated with over-the-counter pain medications.
-
In order to minimize the risk of bleeding or injury to the biopsy site, patients should avoid strenuous activities, heavy lifting, and vigorous exercise for a few days following the procedure.
Risks
Generally, liver biopsy is considered safe, but there are risks and complications associated with the procedure, including:
-
The most common complication of liver biopsy is bleeding at the biopsy site. In rare cases, bleeding that is excessive may require medical intervention, such as blood transfusion or surgical intervention.
-
Some patients may experience pain, discomfort, or bruising at the biopsy site following the procedure. This is usually temporary and will disappear within a few days.
-
The biopsy site is at risk for infection, which may manifest as fever, chills, or increased pain. If symptoms of infection occur, seek immediate medical attention.
Aftercare
The following instructions should be followed after a liver biopsy:
-
After the biopsy procedure, rest for the remainder of the day to promote healing and reduce complications.
-
To minimize bleeding or injury to the biopsy site, avoid strenuous activities, heavy lifting, or vigorous exercise for a few days after the procedure.
-
Review biopsy results, assess recovery progress, and address any concerns or complications at all scheduled follow-up appointments with the healthcare provider.
