|Liver Transplantation
🩺 Liver transplantation is the definitive treatment for acute or chronic liver failure.
🚧 The main limiting factor is the shortage of donor organs. Living donors (usually family members) are increasingly used.
📖 About
- ✅ Highly successful and effective treatment for liver failure.
- 🔄 Can be done acutely (fulminant failure) or electively (chronic disease).
- 👵 Usually offered to patients <65 years.
- 📊 MELD (Model for End-Stage Liver Disease) score helps prioritise patients on the waiting list.
🫀 Source of Transplant
- 💀 Deceased donor (orthotopic): Liver from a recently deceased individual, transplanted into recipient.
- 🫂 Living donor: A segment of liver from a healthy donor (often a family member). Both segments regenerate within weeks.
- 🔑 Factors: ABO blood type compatibility, donor <60 yrs, appropriate size match.
🔪 The Procedure
- “Mercedes-Benz” incision used (rooftop + vertical extension).
- ⏱️ Surgery takes 6–12 hours.
- Non-functioning liver is removed → replaced with donor liver.
🚨 Acute Need for Transplant
- 💊 Paracetamol overdose.
- 🦠 Fulminant viral hepatitis.
📏 King’s College Criteria
Paracetamol-induced liver failure
- Arterial pH <7.3 after 24h OR
- PT >100 sec, Creatinine >300 μmol/L, and Grade III–IV encephalopathy.
Non-paracetamol induced
- PT >100 sec OR
- 3 of: Age <10 or >40, >1 week from jaundice → encephalopathy, PT >50 sec, Bilirubin >300 μmol/L, drug-induced cause.
📌 Indications (Chronic/Advanced Disease)
- Primary biliary cholangitis (PBC).
- Recurrent variceal haemorrhage.
- Intractable ascites or SBP.
- Refractory encephalopathy.
- Severe jaundice or synthetic dysfunction (low albumin, ↑INR).
- Fulminant hepatic failure (any cause).
🧾 Pre-Operative Work-up
- 🧪 Bloods: FBC, LFTs, coagulation, U&E, glucose.
- 📉 Crossmatch at least 10 units RBC.
- 📈 ECG & CXR to check fitness.
- 🖼️ Abdominal USS (if not done in last 4 months).
🛑 Contraindications
- ❌ Extra-hepatic malignancy.
- ❌ Active uncontrolled sepsis (e.g. SBP).
- ❌ Widespread liver metastases.
⚠️ Complications
- 💀 Death, 💉 haemorrhage, 🦠 sepsis.
- ⛔ Acute rejection (immune-mediated).
- Chronic rejection → graft loss.
💊 Prevention of Rejection
- Calcineurin inhibitors: Ciclosporin, Tacrolimus.
- Immunosuppressants: Azathioprine.
- Adjunct: Steroids.
📊 Risk of Rejection
- ⬆️ High risk: previous rejection, younger patients, females, autoimmune disease (AIH, PBC).
- ⬇️ Lower risk: malnourished patients, renal failure.
📚 Exam tip for OSCEs: Always mention King’s College Criteria in fulminant hepatic failure stations.
Discuss both indications (e.g. variceal bleeds, refractory ascites) and contraindications (malignancy, sepsis).
Cases — Liver Transplantation
- Case 1 — Acute liver failure ⚡: A 28-year-old woman presents with jaundice, confusion, and coagulopathy 3 days after a paracetamol overdose. Bloods: INR 5.2, bilirubin 300 µmol/L, ALT 4500. She develops encephalopathy (grade 3). King’s College criteria met. Diagnosis: acute fulminant liver failure requiring urgent transplantation. Managed with ICU care and immediate transplant listing.
- Case 2 — Decompensated cirrhosis 🍺: A 55-year-old man with alcoholic cirrhosis presents with recurrent ascites, variceal bleeding, and hepatic encephalopathy despite maximal therapy. MELD score: 24. Ultrasound: cirrhotic liver, no HCC. Diagnosis: end-stage cirrhosis requiring elective liver transplantation. Managed with transplant listing and abstinence support.
- Case 3 — Hepatocellular carcinoma (HCC) 🎗️: A 63-year-old woman with hepatitis C cirrhosis is found to have a 2.5 cm liver lesion on screening ultrasound. MRI confirms HCC within Milan criteria (single lesion <5 cm, no extrahepatic spread). Diagnosis: HCC in cirrhotic liver — transplant candidate. Managed with listing for transplantation and bridging therapy (radiofrequency ablation).
Teaching Point 🩺: Indications for liver transplantation include acute liver failure, decompensated cirrhosis, and HCC (within Milan criteria). Prognostic tools such as MELD and Child-Pugh scores guide timing. Contraindications include active alcohol misuse, uncontrolled infection, and extrahepatic malignancy.
