The Liver
▪ The largest single organ in the human
body.
▪ In an adult, it weighs about 1.5 Kg and is
roughly the size of a football.
▪ Located in the upper right-hand part of the
abdomen, behind the lower ribs.
What does the liver do?
Multi-function, blood-processing “factory”
• Temporary nutrient storage (glucose-glycogen)
• Remove toxins from blood
• Remove old/damaged RBC’s
• Regulate nutrient or metabolite levels in blood—keep constant
supply of sugars, fats, amino acids, nucleotides (including
cholesterol)
• Secrete bile via bile ducts and gall bladder into small intestines.
What is liver Transplantation
▪ Liver Transplantation is the replacement of a diseased liver with a healthy
liver allograft.
▪ Used technique is orthotropic transplantation, in which the native liver is
removed and replaced by the donor organ in the same anatomic location as
the original liver.
Brief History
▪ Liver replacement in more than 150 dog experiments
between 1958-61
▪ Between March 1 and October 4, 1963, Starzl attempted
5 human liver replacements. The first patient bled to
death during the operation. The other 4 died after 6.5 to
23 days with functioning grafts
▪ Julie Rodriguez, the child sitting on the knee of the
Swedish surgeon, Carl Groth (Figure), became the first
human liver recipient with survival exceeding one year.
▪ Despite the development of viable surgical techniques,
liver transplantation remained experimental through the
1970s, with one year patient survival in the vicinity of
25%.
Why Liver Transplant ???
Reasons of Liver transplant
LIVER FUNCTION TESTS
▪ LFT (Liver Function Test)
▪ ALT (Alanine Transaminase enzyme)
▪ AST (SGOT) (Aspartate Aminotransferase Test)
▪ ALKALINE PHOSPHATASE
▪ BILIRUBIN
▪ PROTHROMBIN TIME/INR (measures how long it takes blood to clot)
▪ ALBUMIN
Acute Liver Disease
▪ Infections
▪ Viral Hepatitis A, B, C, D, E, EBV, CMV, HSV,
▪ Others – Leptospirosis, Toxoplasma,
▪ Drugs – MANY – HERBALS/OTC
▪ Alcohol
▪ Toxins
▪ Vascular obstruction (eg. Budd-Chiari)
(Blockage of a blood vessel)
Chronic Liver Disease
▪ Alcohol
▪ Viral hepatitis: B & C
▪ Autoimmune – autoimmmune hepatitis, PBC (Primary Biliary cirrhosis), PSC
(Primary Sclerosing Cholangitis)
▪ Non-alcoholic fatty liver disease (NAFLD)
▪ Drugs (MTX, amiodarone)
▪ Haemochromatosis
▪ Cystic fibrosis, a1antitryptin deficiency, Wilsons disease,
▪ Vascular problems (Portal hypertension + liver disease)
▪ Cryptogenic (Disease whose cause is unkown)
▪ Others: sarcoidosis, amyloid, schistosomiasis

When Liver Transplantation
Issues
▪ Whether patient needs LT?
▪ When to refer or consider for LT?
▪ Is patient suitable for LT?
Scoring systems
CHILD-TURCOTTE - PUGH SCORE
Measure 1 point 2 points 3 points
Total Bilirubin (mg/dl) < 2 2-3 >3
Serum albumin (g/dl) >3.5 2.8-3.5 <2.8
INR <1.7 1.71-2.3 > 2.3
Ascites None Slight/Suppressed with
medication
Moderate despite
diuretics/Refractory
Hepatic encephalopathy None Grade I-II Grade III-IV
CTP score:
- Disease severity for pts with ESLD
- Used to predict peri-operative mortality in patients with liver disease.
Model for End-Stage Liver Disease (MELD)
▪ MELD score = 0.957 x Loge (creatinine mg/dl) + 0.378 x Loge (bilirubin mg/dl) + 1.12
x Loge (INR) + 0.643
Multiply the score by 10 and round to the nearest whole number
▪ Established in Feb 2002
▪ Numerical scale, from 6 (less ill) to 40 (gravely ill)
▪ This ‘score’ tells us how urgently LT is required within next 3 months
▪ Most patients on LT waiting list have MELD score between 11 and 20
Living related liver transplant
: Donor requirements
▪ Unsolicited volunteer
▪ Family member (not necessarily blood relative)
▪ No clear medical contra-indications
▪ Size appropriate
▪ ABO matched (Blood group system)
▪ Age <50
▪ Normal liver, HIV negative (Human immuno deficiency virus)
Donor problems
▪ Biliary complications (Liver Blood vessels) 6%
▪ Re-operation 5%
▪ Death <0.3%
▪ Mean ICU Stay 0.5 days
▪ Hospital Stay 6.4 days

Recipient Issues
▪ Re-transplant rate 2.5%
▪ Acute liver Failure (Complete dead) 2%
▪ Biliary complications 23%
▪ Arterial complications 8%

Shortcomings of CTP scores
• Subjective nature of the assessment of ascites & encephalopathy
• Limited discrimination into only three disease severity categories
Infection post Transplant
▪ Week 1
▪ Hepatic Artery thrombosis
▪ Portal Vein thrombosis
▪ Infections (Bacterial/Viral/Fungal)
▪ Drug toxicity
▪ Renal Impairment
▪ Acute cellular rejection
▪ Month 1
▪ Nosocomial infection (Hospital acquired infections)
▪ Bacteria and fungi
▪ 19-28% of patients have bacteremia Staph, Enterococcus (50-60%)
