Liver Transplant: Who Needs It, How It Works and What to Expect

What Is a Liver Transplant?

A liver transplant is an operation in which a severely diseased or damaged liver is removed and replaced with a healthy liver, or part of a liver, from a donor.

It is usually considered when the liver can no longer perform its essential functions and other treatments are no longer sufficient. For appropriately selected patients with advanced liver failure, transplantation can be life-saving.

Who May Need a Liver Transplant?

Liver transplantation may be considered for patients with conditions such as:

Advanced liver cirrhosis

Acute liver failure

Certain liver cancers

Advanced fatty liver disease

Chronic viral or autoimmune liver disease

Some inherited or metabolic liver disorders

Certain diseases affecting the bile ducts

Having serious liver disease does not automatically mean that a transplant is required. Doctors consider the severity of liver damage, the patient's overall health and whether transplantation is expected to provide a meaningful long-term benefit.

How Is a Patient Evaluated?

Before transplantation, patients undergo a detailed assessment at a transplant center.

This may include blood tests, liver imaging, heart and lung evaluation, kidney function tests, infection screening and cancer assessment when appropriate.

The transplant team also evaluates the patient's general health, nutritional condition and ability to follow the long-term treatment plan required after surgery.

The final decision is made by a multidisciplinary transplant team.

Living Donor and Deceased Donor Transplantation

A liver for transplantation can come from a deceased donor or a living donor.

Deceased Donor

A suitable liver from a deceased donor can be transplanted into an approved recipient. Allocation and waiting-list procedures depend on the country's transplant system and the urgency of the patient's condition.

Living Donor

A healthy person may donate part of their liver to a suitable recipient.

Both the donor and recipient undergo extensive medical evaluation before surgery. Living-donor transplantation can provide an important option for suitable patients, but donor safety must always be a central part of the decision.

What Happens During Liver Transplant Surgery?

During surgery, the damaged liver is removed and the donor liver is placed in the patient's body.

Surgeons connect the transplanted liver to the major blood vessels and bile ducts so that it can begin functioning.

Liver transplantation is a complex procedure that can take many hours. After surgery, the patient is usually monitored closely in an intensive care unit.

Recovery After a Liver Transplant

During the first days after surgery, doctors monitor how well the transplanted liver is working and watch for complications.

Blood tests are performed frequently, and the patient's heart, lungs, kidneys and circulation are also monitored.

Many patients can leave the hospital around two weeks after transplantation, although recovery time varies considerably depending on the individual.

Regular follow-up continues after discharge.

Rejection and Immunosuppressive Medication

The immune system can recognize the transplanted liver as foreign and attempt to attack it. This is called rejection.

Patients therefore need immunosuppressive medicines to reduce the risk of rejection. These medications are generally required long term and must be taken exactly as prescribed.

Because immunosuppressive medicines reduce immune activity, they can also increase the risk of infection and cause other side effects.

What Are the Main Risks?

Possible complications of liver transplantation include:

Bleeding

Infection

Blood clots

Bile duct problems

Organ rejection

Problems with the transplanted liver

Side effects from immunosuppressive medicines

Risks vary between patients, which is why careful evaluation before transplantation is essential.

Life After Liver Transplantation

Many patients are able to gradually return to work, physical activity and everyday life after recovery.

Long-term success depends on regular medical follow-up, taking medication correctly, maintaining a healthy lifestyle and reporting new symptoms promptly.

A liver transplant should be viewed as a long-term treatment process rather than a single operation. Patients with advanced liver disease should be evaluated by an experienced transplant team to determine whether transplantation is appropriate and which donor option may be suitable.
