11 Things to Know About a Liver Biopsy

A liver biopsy may be recommended when blood tests or imaging reveal an abnormality that cannot be fully explained. Understandably, patients may have questions about what the biopsy can detect, whether the procedure is painful, and how long recovery will take.

1. What Is a Liver Biopsy?

A liver biopsy is a procedure in which a doctor removes a small sample of liver tissue for examination under a microscope.

In most cases, the sample is collected using a thin biopsy needle inserted through the skin and into the liver. A pathologist then examines the tissue for abnormal cells, inflammation, infection, fat accumulation, scarring, or other changes.

2. Why Might I Need a Liver Biopsy?

A biopsy may be recommended when an ultrasound, CT scan, or MRI identifies an unexplained liver abnormality.

The results can help determine whether the abnormality is:

๐ Liver cancer

๐ Cancer that has spread to the liver from another organ

๐ A non-cancerous liver tumour

๐ Infection or inflammation

๐ Fatty liver disease

๐ Fibrosis or cirrhosis

For patients who have already been diagnosed with cancer, a biopsy may provide information about the tumour’s type and biological characteristics, which can help guide treatment decisions.

3. What Types of Liver Biopsy Are Available?

The method selected depends on the location of the abnormality, the patient’s health, and the risk of bleeding.

Percutaneous Liver Biopsy

This is the most common method. A needle is passed through the skin into the liver to collect a tissue sample.

Ultrasound or CT imaging is often used to identify the safest and most accurate location for the biopsy.

Transjugular Liver Biopsy

A thin tube is inserted through a vein in the neck and guided through the blood vessels to the liver.

This method may be considered for patients who have:

๐ A high risk of bleeding

๐ Blood-clotting abnormalities

๐ A large amount of abdominal fluid

Laparoscopic or Surgical Biopsy

A tissue sample may occasionally be collected during keyhole surgery or another abdominal operation.

This approach may be used when the doctor needs to examine the liver directly or collect samples from several areas.

4. What Can a Liver Biopsy Detect Besides Cancer?

A liver biopsy may help diagnose or assess several conditions, including:

๐ Liver abscess: A collection of pus caused by infection

๐ Autoimmune liver disease: Such as autoimmune hepatitis

๐ Bile duct inflammation: Including primary sclerosing cholangitis

๐ Fibrosis and cirrhosis: Progressive scarring of liver tissue

๐ Liver cysts: Fluid-filled sacs within the liver

๐ Fatty liver disease: Accumulation of fat within liver cells

๐ Benign liver tumours: Such as focal nodular hyperplasia or hepatic adenoma

๐ Infections: Including certain bacterial, viral, fungal, or parasitic infections

๐ Inflammatory liver conditions

A biopsy may also be used to evaluate liver damage associated with medicines or cancer treatments, including chemotherapy and immunotherapy.

5. How Long Does a Liver Biopsy Take?

The tissue-collection procedure itself commonly takes approximately 20-30 minutes.

The total time may be longer, sometimes around 45-90 minutes, depending on:

๐ The biopsy method

๐ The location of the lesion

๐ The number of samples required

๐ The need for imaging guidance

๐ The patient’s medical condition

Additional time is required for preparation and post-procedure observation.

6. What Are the Risks?

A liver biopsy is generally safe when performed by an experienced medical team, but complications are possible.

Bleeding

Bleeding is the main potential complication. Minor bleeding often stops without treatment, while significant internal bleeding is uncommon but may require urgent medical care.

Pain

Pain or discomfort around the biopsy site is relatively common. Some patients may also feel pain in the right shoulder because of irritation near the diaphragm.

Infection

Infection is uncommon but may occur, particularly if the biopsy involves an infected area.

Other rare complications may include injury to a nearby organ, lung, gallbladder, or blood vessel.

7. Is General Anaesthesia Required?

General anaesthesia is not usually necessary for a standard percutaneous liver biopsy.

Patients commonly receive:

๐ Local anaesthetic to numb the skin and deeper tissues

๐ Intravenous sedation when needed to reduce anxiety and discomfort

The patient may remain awake but relaxed during the procedure. General anaesthesia may be used for selected surgical or laparoscopic biopsies.

8. How Painful Is a Liver Biopsy?

Most patients experience only mild or moderate discomfort because local anaesthetic is used.

Possible sensations include:

๐ Pressure at the biopsy site

๐ A brief sharp pain when the needle enters the liver

๐ Mild soreness afterwards

๐ Temporary pain extending to the right shoulder

Severe or increasing pain after the procedure should be reported immediately because it may indicate bleeding or another complication.

9. Is a Liver Biopsy a Major Procedure?

A liver biopsy involves an important internal organ and must therefore be performed carefully. However, a needle biopsy is considered a minimally invasive procedure rather than major surgery.

The overall complication rate is low when:

๐ The patient is properly assessed beforehand

๐ Blood-clotting tests are reviewed

๐ Appropriate imaging guidance is used

๐ The patient is monitored after the procedure

10. How Long Must I Stay at the Hospital?

Most percutaneous liver biopsies are performed as day procedures, allowing the patient to return home on the same day.

After the biopsy, patients are usually monitored for several hours. During this period, the medical team may check:

๐ Blood pressure

๐ Heart rate

๐ Breathing

๐ Pain level

๐ The biopsy site

๐ Signs of internal bleeding

Patients who receive sedation should arrange for someone to drive them home and stay with them during the initial recovery period.

An overnight hospital stay may be necessary if complications develop or if the patient has significant underlying health conditions.

11. How Long Does Full Recovery Take?

Many patients can return to desk work or other light activities the following day, depending on how they feel and the doctor’s advice.

After the procedure:

๐ Rest for the remainder of the day.

๐ Avoid driving for the period recommended by the medical team, particularly after sedation.

๐ Avoid strenuous exercise.

๐ Avoid heavy lifting for approximately one to two weeks or as instructed by the doctor.

๐ Keep the biopsy site clean and dry.

๐ Take only pain medication approved by the doctor.

Recovery instructions may vary according to the biopsy method and the patient’s risk factors.

Warning Signs After a Liver Biopsy

Seek immediate medical attention if you experience:

๐ Severe or worsening abdominal pain

๐ Persistent right shoulder pain

๐ Dizziness, weakness, or fainting

๐ Shortness of breath

๐ A rapid heartbeat

๐ Fever or chills

๐ Increasing redness, swelling, or discharge from the biopsy site

๐ Heavy or persistent bleeding

๐ Abdominal swelling

These symptoms may indicate bleeding, infection, or injury to a nearby structure.

When Will the Results Be Available?

The tissue sample must be prepared and examined by a pathologist. Results are commonly available within several days, although specialised tests may take longer.

The doctor will explain:

๐ What was found in the tissue

๐ Whether the condition is cancerous or non-cancerous

๐ The severity of inflammation or scarring

๐ Whether additional tests are required

๐ The recommended treatment or follow-up plan

A liver biopsy can provide valuable information that imaging and blood tests alone may not reveal, helping the medical team establish an accurate diagnosis and select the most appropriate treatment.
