Liver Transplant: Life‑Saving Treatment for End‑Stage Liver Failure
Quick Summary
- End‑stage Liver Failure is a life‑threatening condition that often requires a transplant.
- Liver Transplant replaces the diseased organ with a healthy donor liver.
- Two donor pathways exist - living donor and deceased donor - each with distinct risks and waiting times.
- Eligibility hinges on the MELD score, transplant centre assessment, and organ‑allocation rules.
- Post‑surgery survival exceeds 80% at five years when immunosuppression is managed properly.
Understanding End‑Stage Liver Failure
Liver Failure is a condition where the liver can no longer perform its essential metabolic, synthetic and detoxifying functions. Common causes include chronic hepatitis C, alcoholic liver disease, non‑alcoholic steatohepatitis (NASH) and genetic disorders such as Wilson’s disease. In the United Kingdom, roughly 1,600 patients are listed for a liver transplant each year, and mortality without transplantation rises sharply after a MELD (Model for End‑Stage Liver Disease) score of 15.
The liver’s inability to clear toxins leads to jaundice, ascites, hepatic encephalopathy and bleeding tendencies. When medical therapy fails, the only curative option is organ replacement.
What Is a Liver Transplant?
Liver Transplant is a surgical procedure that removes a diseased liver and replaces it with a healthy donor graft. The operation typically lasts 6-10hours and requires a multidisciplinary team: transplant surgeons, hepatologists, anesthesiologists, and transplant coordinators. According to the British Transplant Society, 5‑year survival after a first‑time transplant now exceeds 80% in high‑volume centres.
The graft can come from a living donor - usually a relative who donates a portion of their liver - or from a deceased donor whose organ becomes available through the national allocation system.
Types of Liver Donation
Choosing between a living donor and a deceased donor hinges on medical urgency, donor availability and patient preference. Below is a side‑by‑side comparison.
| Attribute | Living Donor | Deceased Donor |
|---|---|---|
| Source | Living Donor - a healthy relative or friend | Deceased Donor - organ recovered after brain death |
| Waiting Time | Weeks to months (planned) | Variable, often several months to years |
| Graft Survival (5‑yr) | ~90% | ~80% |
| Recipient Risks | Higher early‑post‑op complications due to smaller graft volume | Risk of organ‑cold‑ischemia injury |
| Donor Risks | Major abdominal surgery; 0.1‑0.5% serious complication rate | None (donor is deceased) |
Evaluating Candidates for Transplant
The first step is an objective assessment of disease severity. The MELD Score is a numeric scale (6‑40) that predicts three‑month mortality based on bilirubin, INR and creatinine. A score above 15 typically triggers placement on the national waiting list.
Patients are then referred to a Transplant Center, which conducts a comprehensive evaluation - cardiac work‑up, infection screening, psychosocial assessment and imaging studies. Only centres accredited by NHS Blood and Transplant can list patients for organ allocation.
The organ allocation system prioritises based on MELD, blood type compatibility, donor‑recipient size match, and geographical proximity to minimise cold‑ischemia time. Patients with acute liver failure or hepatocellular carcinoma receive special exception points.
Surgery and Immediate Post‑Operative Care
During the operation, the recipient’s diseased liver is removed and the donor graft is implanted. Vascular anastomoses (hepatic artery, portal vein, hepatic veins) and bile duct reconstruction are the most technically demanding steps.
After surgery, patients enter an intensive‑care unit for close monitoring of graft function, blood flow, and signs of rejection. Immunosuppression therapy, typically a combination of tacrolimus, mycophenolate mofetil and steroids, is started immediately to prevent immune‑mediated graft injury. Blood levels are adjusted daily during the first two weeks, then tapered over months.
Complications can include vascular thrombosis, biliary leaks, infection and acute rejection. Early detection via Doppler ultrasound and liver function tests is crucial.
Long‑Term Outcomes and Quality of Life
When immunosuppression is well‑controlled, most recipients enjoy a dramatic improvement in quality of life. Studies from the European Liver Transplant Registry report a 5‑year Post‑Transplant Survival rate of 82% for adults and 85% for pediatric patients.
Long‑term risks include chronic kidney disease, metabolic syndrome, and malignancies linked to lifelong immunosuppression. Lifestyle modifications-balanced diet, regular exercise, abstaining from alcohol-are strongly advised.
Follow‑up care involves quarterly liver function tests for the first year, then bi‑annual monitoring. Patients remain on low‑dose immunosuppression indefinitely, but many centres are exploring protocol‑driven withdrawal for low‑risk individuals.

Frequently Asked Questions
How long does a liver transplant surgery take?
The operation usually lasts between six and ten hours, depending on whether the graft is from a living or deceased donor and on the recipient’s anatomy.
What is the typical waiting time for a deceased‑donor liver?
Waiting time varies widely but averages 9‑12 months in the UK. Urgency, blood type, and MELD score can shorten or lengthen this period.
Can a living donor donate a portion of their liver safely?
Yes. The donor’s remaining liver regenerates to near‑normal size within 6‑8 weeks. Serious complications occur in less than 0.5% of donors.
What are the main side effects of immunosuppressive drugs?
Common side effects include increased infection risk, high blood pressure, kidney dysfunction, tremor, and weight gain. Regular monitoring helps mitigate these risks.
How is graft function monitored after surgery?
Doctors track liver enzymes (ALT, AST), bilirubin, INR, and imaging studies such as Doppler ultrasound to ensure adequate blood flow and early detection of rejection.
Is a second liver transplant ever needed?
Yes. About 10‑15% of recipients may require retransplantation due to chronic rejection, recurrent disease, or graft failure.
How does alcohol consumption affect post‑transplant outcomes?
Continued heavy drinking dramatically raises the risk of graft loss and mortality. Most centres require a six‑month abstinence period before listing.
What lifestyle changes are recommended after a liver transplant?
Patients should follow a balanced low‑sodium diet, maintain a healthy weight, avoid alcohol, stay up‑to‑date with vaccinations, and attend regular clinic appointments.
