Liver Transplantation

Liver transplantation is a life-saving surgical procedure that replaces a diseased liver with a healthy donor liver. It is recommended when liver function deteriorates to the point that medical therapy can no longer maintain survival or quality of life.

It is most commonly performed for:

• End-stage cirrhosis (from hepatitis B, hepatitis C, alcohol-related liver disease, or metabolic dysfunction–associated steatotic liver disease)
• Acute liver failure
• Certain inherited metabolic disorders
• Selected cases of early-stage hepatocellular carcinoma (under defined clinical criteria)

The liver performs essential functions including detoxification, protein synthesis, bile production, and regulation of metabolism. When these functions fail, complications such as ascites, variceal bleeding, hepatic encephalopathy, and coagulopathy may develop. Transplantation restores these critical physiological processes.

Comprehensive Transplant Evaluation

Before listing, patients undergo a multidisciplinary assessment involving hepatologists, transplant surgeons, cardiologists, anesthesiologists, and infectious disease specialists.

Evaluation typically includes:

• Liver imaging (contrast-enhanced CT or MRI)
• Cardiac assessment (echocardiogram, stress testing)
• Pulmonary function testing
• Laboratory analysis (coagulation profile, kidney function, viral serology)
• Cancer screening
• Nutritional evaluation
  
  
  

Listing and Organ Allocation

Patients are placed on a transplant waiting list once approved. Allocation is commonly based on disease severity using scoring systems such as MELD (Model for End-Stage Liver Disease), which predicts short-term mortality risk.

While waiting, patients must:

• Attend regular follow-up visits
• Maintain abstinence from alcohol
• Control infections and complications
• Remain reachable at all times for potential organ offers

When an Organ Becomes Available

Once a donor liver is matched, patients are urgently admitted to the hospital. Final cross-matching tests are performed, and surgery proceeds under general anesthesia.

During Surgery

The procedure typically lasts 6 to 12 hours.

Key surgical steps include:

• Removal of the diseased liver.
• Implantation of the donor liver.

Reconstruction of:

• The hepatic artery
• Portal vein
• Inferior vena cava (or modified technique preserving it)
• Bile duct connection
  
  

Meticulous vascular reconstruction is essential to ensure proper blood flow to the transplanted organ.

Immediate Postoperative Care

After surgery:

• Patients are transferred to the ICU.
• Mechanical ventilation is commonly required initially.
• Continuous monitoring of blood pressure, liver function tests, clotting factors, and urine output is performed.
• Immunosuppressive therapy is started early to prevent rejection.
  
  

The average hospital stay ranges from 2 to 3 weeks, depending on recovery and complications.

Early Recovery Phase

Patients gradually transition from intensive monitoring to rehabilitation, focusing on:

• Early mobilization
• Nutritional support
• Infection prevention
• Medication education

Early (Short-Term) Risks

• Bleeding requiring transfusion
• Primary graft non-function
• Hepatic artery thrombosis
• Bile leak or bile duct stricture
• Acute cellular rejection
• Severe infection

Long-Term Risks

• Chronic rejection
• Recurrent liver disease (e.g., viral hepatitis)
• Renal dysfunction due to immunosuppressive medications
• Hypertension, diabetes, hyperlipidemia
• Increased risk of certain malignancies due to long-term immunosuppression
  
  

Although these risks are significant, outcomes have improved markedly with modern surgical techniques and immunosuppressive regimens.

Survival rates after liver transplantation continue to improve globally. Many recipients achieve long-term survival and return to normal daily activities.

Long-term follow-up includes:

• Frequent laboratory testing (especially during the first year)
• Drug level monitoring
• Imaging as needed
• Cancer surveillance
• Vaccination and infection prevention strategies
  
  

Strict adherence to immunosuppressive therapy is critical. Missing doses significantly increases the risk of organ rejection.

Lifestyle recommendations include:

• Balanced nutrition
• Avoidance of alcohol
• Regular physical activity
• Cardiovascular risk management
