Liver transplantation is a life-saving surgical procedure that replaces a failing or diseased liver with a healthy one from a donor. This treatment offers people with end-stage liver disease or acute liver failure a chance at restored health, improved quality of life, and extended survival, often adding 15 years or more to their lifespan.

When Replacing the Liver Becomes Necessary

Liver transplantation represents the ultimate treatment option when all other medical approaches have failed to control severe liver damage. The liver is the body’s largest internal organ, performing critical functions that keep us alive. It filters toxins from the blood, processes nutrients and medications, produces proteins that help blood clot, makes bile for digesting fats, and supports the immune system. When the liver stops working properly, these essential tasks cannot be performed, and without intervention, life cannot continue.^[1]

The procedure is typically reserved for people experiencing significant complications from end-stage chronic liver disease, a condition where the liver has been damaged over time to the point where it can no longer function adequately. Transplantation may also be considered in rare cases of acute liver failure, where a previously healthy liver suddenly stops working, often within days or weeks. This can happen from overdosing on medications like acetaminophen, reactions to prescription or illegal drugs, exposure to toxins, or viral infections.^[3]

In the United States, the most common reasons adults need liver transplants include alcoholic liver disease, liver cancers that develop alongside cirrhosis, fatty liver disease, and cirrhosis caused by chronic hepatitis C infection. For children, the leading cause is a condition called biliary atresia, where bile ducts are blocked or absent from birth.^[3]

Doctors may also consider transplantation for rare inherited disorders such as urea cycle disorders, familial hypercholesterolemia, and certain metabolic diseases where the liver cannot perform specific chemical processes needed for survival. Additionally, people with certain types of liver cancer that have not spread beyond the liver, particularly hepatocellular carcinoma within specific size limits, may be eligible for transplantation.^[4]

Standard Treatment Approach: Managing End-Stage Liver Disease Before Transplant

Before a liver transplant can take place, patients often spend months or even years managing the complications of their failing liver with various medical treatments. This period requires close monitoring by liver specialists called hepatologists and frequent hospital or clinic visits. The goal of these treatments is to control symptoms, prevent life-threatening complications, and keep patients as healthy as possible while they wait for a donor organ to become available.^[14]

One of the most troublesome problems people with end-stage liver disease face is ascites, which is the buildup of fluid in the abdomen. This happens because the damaged liver cannot maintain proper fluid balance in the body. Initial treatment typically involves restricting salt in the diet, though this works in fewer than 20 percent of patients. The main medical approach involves diuretic medications such as spironolactone, furosemide, and hydrochlorothiazide. These medicines help the kidneys remove excess fluid from the body. However, they must be carefully adjusted because they can cause electrolyte imbalances or worsen kidney function. If diuretics stop working or cause too many side effects, doctors may need to drain the fluid directly from the abdomen using a needle in a procedure called paracentesis. Some patients require this uncomfortable procedure once or twice every week.^[14]

Another serious complication is spontaneous bacterial peritonitis, an infection of the fluid in the abdomen that can be deadly if not treated promptly. Patients with severe ascites or previous episodes of infection often take preventive antibiotics such as rifaximin, sometimes combined with quinolone antibiotics, to reduce the risk of these infections developing. When infection does occur, doctors start antibiotic treatment immediately, targeting the bacteria most commonly responsible, which are usually gram-negative organisms from the intestines.^[14]

Hepatic encephalopathy is a condition where toxins that the damaged liver can no longer filter build up in the bloodstream and affect the brain. This causes confusion, personality changes, forgetfulness, difficulty thinking clearly, trembling hands, slurred speech, and in severe cases, patients may not know where they are or who people around them are. Some people experience reversed sleep patterns, staying awake at night and sleeping during the day. The main medication used to treat this condition is lactulose, a liquid that increases bowel movements to help remove toxins from the body. While effective, lactulose often causes severe diarrhea and stomach cramping, making it difficult for some people to tolerate. Another medication called Xifaxin (rifaximin) may also be prescribed to reduce ammonia-producing bacteria in the gut.^[17]

Patients may also develop enlarged veins in the throat or esophagus called varices, which can rupture and cause life-threatening bleeding. To prevent this, doctors may perform a procedure called variceal banding, where they place small rubber bands around these swollen veins to seal them off. In some cases, a surgical procedure called TIPS (transjugular intrahepatic portosystemic shunt) may be performed. This involves placing a small tube called a stent inside the liver to redirect blood flow and reduce pressure in the veins. However, TIPS carries risks of worsening liver function and increasing the severity of hepatic encephalopathy, especially in patients with very advanced liver disease.^[14]

When patients with advanced cirrhosis also develop kidney problems, a dangerous condition called hepatorenal syndrome may occur. This happens when blood flow to the kidneys decreases dramatically due to the failing liver. It is defined by rising creatinine levels above 1.5 milligrams per deciliter, very low urine output (less than 500 milliliters per day), and very low sodium levels in the urine (less than 10 milliequivalents per liter). This condition is difficult to treat and often requires hospitalization to manage fluid and electrolyte balance carefully.^[14]

For patients with liver cancer, particularly hepatocellular carcinoma, a procedure called transarterial chemoembolization (TACE) may be used as a bridge therapy while waiting for transplant. This involves injecting chemotherapy drugs directly into the blood vessels feeding the tumor and then blocking those vessels to trap the medication in the tumor and cut off its blood supply. This can help control cancer growth and keep patients within the eligibility criteria for transplantation.^[17]

Throughout the waiting period, patients must maintain complete abstinence from alcohol and drugs, regardless of whether alcohol was the cause of their liver disease. Transplant centers conduct random drug and alcohol tests to ensure compliance, as substance use can disqualify someone from receiving a transplant. Patients often work with specialized addiction nurses or psychiatrists to address substance use disorders and demonstrate their commitment to staying sober after transplant.^[17]

The Transplant Evaluation and Waiting List Process

Before being accepted for transplantation, patients undergo an extensive evaluation by a multidisciplinary team at a transplant center. This team includes transplant surgeons, hepatologists, nurse coordinators, social workers, psychiatrists or psychologists, pharmacists, dietitians, and financial coordinators. The evaluation involves many appointments over several days or weeks, during which doctors assess not only the liver disease but also the patient’s overall physical and mental health.^[6]

The medical evaluation includes numerous blood tests to check liver and kidney function, screen for infections including viral hepatitis and HIV, determine blood type, and assess clotting ability. Patients undergo heart evaluations with electrocardiograms and stress tests to ensure the heart is strong enough for surgery. Imaging studies such as CT scans, ultrasounds, and sometimes MRI scans examine the liver and look for cancer or other abnormalities. Lung function tests, dental examinations, and cancer screenings are also performed. In some cases, liver biopsies may be needed to determine the extent of damage.^[11]

The transplant team carefully evaluates whether patients can survive the operation and recovery, whether they will take all required medications as prescribed, and whether they have adequate support from family or caregivers. Patients must identify a primary caregiver who can be with them at appointments, help after surgery, and provide ongoing support. The team also assesses whether patients have health insurance coverage for the expensive procedure and medications, and social workers help connect patients with financial resources if needed.^[6]

If accepted as a candidate, patients are placed on a national waiting list managed by the United Network for Organ Sharing (UNOS). The waiting list ranks patients based on medical urgency using a scoring system called the Model for End-Stage Liver Disease (MELD). This mathematical formula calculates a score from 6 to 40 based on blood test results that measure how poorly the liver and kidneys are functioning. Higher scores indicate greater illness and risk of death within three months, and patients with higher MELD scores are prioritized to receive transplants sooner. Updated versions of this system, including MELD-sodium and MELD 3.0, incorporate additional factors to improve accuracy in predicting who needs transplant most urgently.^[5]

Patients with acute liver failure, who become critically ill very rapidly, are placed at the top of the waiting list regardless of MELD score because they may die within days without a transplant. Some patients with liver cancer receive MELD exception points because their cancer risk increases over time even if their liver function scores are not as high as others waiting.^[8]

The demand for donor livers far exceeds the supply. In 2018, about 8,200 liver transplants were performed in the United States, but at the same time, approximately 12,800 people were registered on the waiting list. Each week, between 200 and 300 more people join the list. Unfortunately, about 16 percent of people who meet medical criteria for transplant become too sick to undergo surgery or die before a suitable donor liver becomes available.^[1][4]

Types of Donor Livers and Surgical Options

Most liver transplants in the United States—approximately 94 percent—use whole livers from deceased donors, people who have recently died and whose families have agreed to organ donation. When a deceased donor liver becomes available, it is matched to a recipient based on blood type compatibility, organ size, geographic location, and MELD score. The transplant team calls the patient to come to the hospital immediately, and surgery is performed within hours.^[8]

The human liver has a remarkable ability to regenerate, which makes living donor transplantation possible. A healthy person, often a family member or close friend, can donate a portion of their liver to the patient. The donated section is removed surgically, and both the donor’s remaining liver and the transplanted portion in the recipient grow back to nearly normal size within several weeks or months. Living donor transplants account for about 5 to 6 percent of liver transplants. They offer the advantage of not having to wait for a deceased donor, can be scheduled at a time when the patient is healthiest, and generally have better outcomes because the organ is transplanted quickly without prolonged cold storage time.^[1][4]

In some cases, surgeons may split a deceased donor liver into two parts—a larger right lobe and a smaller left lobe. The larger portion typically goes to an adult, while the smaller portion may be transplanted into a child or smaller adult. This technique helps maximize the use of available donor organs, allowing two patients to benefit from one donor.^[3]

A less common approach called domino liver transplantation or sequential transplantation may be used in specific situations. This occurs when a patient with a metabolic disease such as familial amyloid polyneuropathy needs a transplant. Although their liver does not function normally for their disease, it can work adequately in another person. That liver can then be transplanted into a second patient, usually someone with cancer or another condition where time is critical and waiting for a standard donor is not possible.^[9]

The Transplant Surgery

Liver transplant surgery is a major operation that typically takes between 4 and 8 hours, though it can be longer in complicated cases. When a donor liver becomes available, the transplant coordinator contacts the patient, who must travel to the hospital as quickly and safely as possible. Upon arrival, the patient undergoes final preparations including blood tests, sometimes additional imaging, and placement of intravenous lines.^[6]

During the procedure, the surgeon makes a large incision across the upper abdomen called a chevron incision. This starts on the right side just below the ribs, extends across to the left edge of the abdomen, with a short vertical incision from the breastbone meeting the horizontal cut. This extensive incision is necessary to access the liver and the major blood vessels connected to it. The surgeon carefully removes the diseased liver while preserving important structures, then implants the donor liver and reconnects all the blood vessels and bile ducts. The operation requires exceptional surgical skill because the liver has complex connections to major veins and arteries that carry blood to and from the heart and intestines.^[19]

After surgery, patients are taken to the surgical intensive care unit (SICU) where they remain for several days to a week. During this critical time, the medical team monitors the new liver’s function closely through frequent blood tests, watches for signs of bleeding or blood clots, manages pain, and begins giving immunosuppressive medications to prevent rejection. Patients are usually connected to breathing machines initially and have multiple tubes and drains in place. As they stabilize, they are gradually transitioned off life support and moved to a specialized transplant nursing unit.^[6]

The total hospital stay typically lasts 2 to 3 weeks, though it can be shorter for uncomplicated cases or longer if problems arise. Before discharge, patients and caregivers receive extensive education about medications, signs of complications to watch for, wound care, diet, activity restrictions, and when to call the transplant team.^[6]

Life After Transplant: Long-term Management

Living with a transplanted liver requires a lifelong commitment to medical care and lifestyle adjustments. The most critical aspect of post-transplant care is taking immunosuppressive medications (also called anti-rejection drugs) every day without fail. These medications prevent the body’s immune system from recognizing the transplanted liver as foreign and attacking it. Patients typically take two or more different immunosuppressants, and the types and doses may be adjusted over time. Commonly used immunosuppressants include tacrolimus, cyclosporine, mycophenolate, sirolimus, and prednisone.^[15]

These powerful drugs have significant side effects that patients must manage. Because they suppress the immune system, patients become more vulnerable to infections from bacteria, viruses, and fungi. Even common infections can become serious. Other side effects include brittle bones (osteoporosis), diabetes, high blood pressure, high cholesterol and triglyceride levels, kidney damage, and weight gain. Long-term use increases the risk of developing certain cancers, particularly skin cancers and lymphomas. Patients must have regular skin examinations and avoid excessive sun exposure.^[15]

Organ rejection is the most feared complication after transplant. The highest risk occurs in the first 3 to 6 months, but rejection can happen at any time if immunosuppressive medications are not taken correctly. Often, rejection does not cause symptoms that patients notice—abnormal blood test results may be the first sign. When symptoms do occur, they can include fatigue, pain or tenderness in the abdomen where the liver is located, fever, yellowing of the skin and eyes (jaundice), dark-colored urine, and light-colored stools. If rejection is suspected, doctors perform a liver biopsy to examine tissue under a microscope and confirm the diagnosis. Treatment usually involves increasing or changing immunosuppressive medications.^[15]

After transplant, patients have very frequent medical appointments. For the first 2 to 3 months, they typically visit the transplant clinic weekly and have blood tests drawn twice weekly to monitor liver function, kidney function, medication levels, and signs of rejection or infection. As recovery progresses, visits become less frequent—moving to monthly, then every few months, and eventually once or twice yearly for stable patients. However, patients remain connected to the transplant team for life.^[21]

The recovery timeline varies considerably. Most patients need 6 to 12 months before feeling like themselves again and returning to normal activities, though this depends on how healthy they were before transplant. During the first several weeks at home, patients have significant restrictions. They cannot drive while taking pain medications, cannot lift anything heavy, must avoid crowded places where they might be exposed to infections, and need help with daily activities. Physical and occupational therapists often work with patients to rebuild strength and endurance.^[16]

Most patients can return to work within 3 to 6 months after transplant. Playing sports, exercising, traveling, and socializing all become possible again, though some precautions remain necessary. Patients should avoid alcohol completely, as it can damage the new liver. They must be vigilant about food safety to prevent foodborne infections—avoiding raw or undercooked meats, unpasteurized dairy products, raw eggs, and unwashed fruits and vegetables. Good hand hygiene and avoiding people who are sick are important infection-prevention measures.^[18]

Diet plays an important role in post-transplant health. Patients often need high-protein diets to rebuild muscle mass lost during illness. However, many immunosuppressive medications cause weight gain and metabolic changes, so working with a dietitian to maintain healthy weight and control blood sugar, cholesterol, and blood pressure is important. Regular exercise helps manage these issues and improves overall well-being.^[21]

Transplant Outcomes and Long-term Survival

Liver transplantation can have excellent outcomes when patients are carefully selected and receive proper post-transplant care. According to national data, one-year survival rates are approximately 87 to 88 percent for patients receiving deceased donor livers and about 92 percent for those receiving living donor transplants. Five-year survival rates are approximately 76 percent for deceased donor recipients and 81 percent for living donor recipients. Some transplant recipients have lived more than 30 years with their transplanted livers, leading essentially normal lives.^[19]

These statistics represent averages across all patients, including very young children and elderly adults, those who were critically ill at transplant and those with less severe disease. Individual outcomes depend on many factors including age, overall health at the time of transplant, the underlying liver disease, how well the patient follows medical instructions, and whether complications occur.^[5]

The single most important factor in transplant success is taking immunosuppressive medications exactly as prescribed. Failure to comply with the medication regimen is the leading cause of transplant failure and loss of the donated liver. Patients who stop or skip doses risk rejection that may not be reversible, potentially requiring another transplant or resulting in death.^[19]

Quality of life after transplant is generally very good. Most patients report feeling dramatically better than they did with end-stage liver disease. They can work, travel, participate in family activities, and pursue hobbies and interests. However, the need for lifelong medication, frequent medical monitoring, and ongoing risk of complications means transplant recipients must remain actively engaged in their health care. Support groups, either in person or online, can help patients and families cope with the challenges of living with a transplant.^[22]
