Liver Transplant

What is a liver transplant?

A liver transplant is surgery to replace a diseased liver with a healthy liver from another person. A whole liver may be transplanted, or just part of one.  

In most cases the healthy liver will come from an organ donor who has just died (a deceased donor).

Sometimes a healthy living person will donate part of their liver. A living donor may be a family member. Or it may be someone who is not related to you but whose blood type is a good match.

People who donate part of their liver can have healthy lives with the liver that is left.

The liver is the only organ in the body that can replace lost or injured tissue (regenerate). The donor’s liver will soon grow back to normal size after surgery. The part that you receive as a new liver will also grow to normal size in a few weeks.

Why might I need a liver transplant?

You
can’t live without a working liver. If your liver stops working correctly, you may need
a transplant.

A
liver transplant may be advised if you have end-stage liver disease (chronic liver
failure). This is a serious, life-threatening liver disease. It can be caused by several
liver conditions.

Cirrhosis is a common cause of end-stage liver disease. It is a chronic liver disease.
It happens when healthy liver tissue is replaced with scar tissue. This stops the liver
from working correctly.

Other diseases that may lead to end-stage liver disease include:

  • Acute
    hepatic necrosis.
    This is when tissue in the liver dies. Possible reasons
    include acute infections and reactions to medicine, illegal drugs, or toxins.
  • Biliary
    atresia.
    A rare disease of the liver and bile ducts that occurs in
    newborns.
  • Viral
    hepatitis.
    Hepatitis B or C are common causes.
  • NAFLD (nonalcoholic fatty liver disease) or
    NASH (nonalcoholic steatohepatitis).
    With NAFLD, too much fat builds up in
    the liver and damages it. This is not caused by alcohol use. NASH is a form of NAFLD
    that includes fat buildup, hepatitis, and liver cell damage.
  • Metabolic
    diseases.
    Disorders that change the chemical activity in cells affected by
    the liver.
  • Primary
    liver cancers.
    These are cancer tumors that start in the liver.
  • Autoimmune
    hepatitis.
    A redness or swelling (inflammation) of the liver. It happens when
    your body’s disease-fighting system (immune system) attacks your liver.

The transplant evaluation process

If your provider thinks you may be a good candidate for a liver transplant, he or
she will refer you to a transplant center for evaluation. Transplant centers are
located in certain hospitals all over the U.S.

You will have a variety of tests done by the transplant center team. They will
decide if your name should be placed on a national transplant waiting list. The
transplant center team will include:

  • A transplant surgeon
  • A transplant provider specializing in treating the liver (a hepatologist)
  • Transplant nurses
  • A social worker
  • A psychiatrist or psychologist
  • Other team members such as a dietitian, a chaplain, or an anesthesiologist

The transplant evaluation process includes:

  • Psychological and social evaluation. Many different issues are assessed.
    They include stress, financial concerns, and if you will have support from family
    or friends after your surgery.
  • Blood
    tests
    . These tests are done to help find a good donor match and assess
    your priority on the waiting list. They can also help improve the chances that
    your body won’t reject the donor liver.
  • Diagnostic tests. Tests may be done to check your liver and your general
    health. These tests may include X-rays, ultrasounds, a liver biopsy, heart and
    lung tests, colonoscopy, and dental exams. Women may also have a Pap test,
    gynecology exam, and a mammogram.

The transplant center team will review all of your information. Each transplant center has rules about who can have a liver transplant.

You may not be able to have a transplant if you:

  • Have a current or chronic infection that can’t be treated
  • Have
    metastatic cancer (cancer that has spread from its main location to 1 or more
    other parts of the body)
  • Have severe heart problems or other health problems
  • Have a serious condition besides liver disease that would not get better after a transplant
  • Are not able to follow a treatment plan
  • Drink too much alcohol

Getting on the waiting list

If you are accepted as a transplant candidate, your name will be placed on a national transplant waiting list. People who most urgently need a new liver are put at the top of the list. Many people have to wait a long time for a new liver.

You will be notified when an organ is available because a donor has died. You will have to go to the hospital right away to get ready for surgery.

If a living person is donating a part of their liver to you, the surgery will be planned in advance. You and your donor will have surgery at the same time. The donor must be in good health and have a blood type that is a good match with yours. The donor will also take a psychological test. This is to be sure he or she is comfortable with this decision.

What are the risks of a liver transplant?

All
procedures have risks. Some complications from liver surgery may include:

  • Bleeding
  • Infection
  • Blocked blood vessels to the new liver
  • Leakage of bile or blocked bile ducts
  • The new liver not working for a short time right after surgery

Your
new liver may also be rejected by your body’s immune system. Rejection is the body’s
normal reaction to a foreign object or tissue. When a new liver is transplanted into
your body, your immune system thinks it is a threat and attacks it.

To
help the new liver survive in your body, you must take anti-rejection medicines
(immunosuppressive medicines). These medicines weaken your immune system’s response. You
must take these medicines for the rest of your life. Some liver diseases can come back
after a transplant. To help the transplant be more successful, you may be started on
hepatitis B or C medicines ahead of time, if you have these diseases.

How do I get ready for a liver transplant?

  • Your healthcare provider will explain the procedure to you. Ask him or her any questions you have about the surgery.
  • You may be asked to sign a consent form that gives permission to do the surgery. Read the form carefully and ask questions if anything is not clear.
  • For a
    planned living transplant, follow any directions you are given for not eating or
    drinking before the surgery. If your liver is from a donor who has just died, you
    should not eat or drink once you are told a liver is available.
  • You may be given medicine to help you relax (a sedative) before the surgery.

Your
healthcare provider may have other instructions for you based on your health
condition.

What happens during a liver transplant?

Liver transplant surgery requires a hospital stay. Procedures may vary depending on your condition and your provider’s practices.

Generally, a liver transplant follows this process:

  1. You will be asked to remove your clothing and given a gown to wear.
  2. An IV
    (intravenous) line will be started in your arm or hand. Other tubes (catheters) will
    be put in your neck and wrist. Or they may be put under your collarbone or in the
    area between your belly and your thigh (the groin). These are used to check your
    heart and blood pressure, and to get blood samples.
  3. You will be placed on your back on the operating table.
  4. If there is too much hair at the surgical site, it may be clipped off.
  5. A catheter will be put into your bladder to drain urine.
  6. After
    you are sedated, the anesthesiologist will put a tube into your lungs. This is so
    that your breathing can be helped with a machine (a ventilator). The anesthesiologist
    will keep checking your heart rate, blood pressure, breathing, and blood oxygen level
    during the surgery.
  7. The skin over the surgical site will be cleaned with a sterile (antiseptic) solution.
  8. The doctor will make a cut (incision) just under the ribs on both sides of your belly. The incision will extend straight up for a short distance over the breast bone.
  9. The doctor will carefully separate the diseased liver from the nearby organs and structures.
  10. The attached arteries and veins will be clamped to stop blood flow into the diseased liver.
  11. Different surgery methods may be used to remove the diseased liver and implant the donor liver. The method used will depend on your specific case.
  12. The diseased liver will be removed after it has been cut off from the blood vessels.
  13. Your surgeon will check the donor liver before implanting it in your body.
  14. The donor liver will be attached to your blood vessels. Blood flow to your new liver will be started. The surgeon will check for any bleeding where you have stitches.
  15. The new liver will be attached to your bile ducts.
  16. The incision will be closed with stitches or surgical staples.
  17. A drain may be placed in the incision site to reduce swelling.
  18. A sterile bandage or dressing will be applied.
