  1. Dr Allister J Grant Consultant Hepatologist University Hospitals Leicester NHS Trust

  2. IVC Portal Vein Hepatic Artery Splenic Vein CBD Gallbladder SMV Anatomy &Physiology

  3. Anatomy &Physiology

  4. Liver Functions Nutrition/Metabolic – stores glycogen (glucose chains) – releases glucose – absorbs fats, fat soluble vitamins – manufactures cholesterol Bile Salts – lipids derived from cholesterol – dissolves dietary fats (detergent) Bilirubin – breakdown product of haemoglobin

  5. Liver Functions Clotting Factors – manufactures most clotting factors Immune function – Kupfer cells engulf antigens (bacteria) Detoxification – drug excretion (sometimes activation) – alcohol breakdown Manufactures Proteins – albumin – binding proteins

  6. Acute Liver Failure <6 weeks duration Jaundice Encephalopathy Cerebral Oedema Acute Renal Failure Acidosis Hypoglycaemia MOF Chronic Liver Disease >6 months Cirrhosis leading to Recurrent decompensation Ascites Portal Hypertension (variceal bleeding) Encephalopathy Low albumin/Malnutrition Hepatorenal syndrome Hyponatraemia Hepatoma Disease Progression

  7. Disease Progression 100% A B Liver function Cirrhosis Liver Failure C D Years

  8. ALT 13000 Alb 35 Bili 40 Cr 160 Urea 24 INR 3.0 PT 33 Glc 3.6 Ph 7.1 PCO23.2 PO2 12.4 BE -6 24♀ 48hours post POD

  9. ALF • Treat the underlying cause • Resuscitate - Central access early • Give N-Ac regardless of cause • Monitor for hypoglycaemia • Monitor coagulopathy • Antibiotic prophylaxis • Stress Ulcers • Early elective ventilation for encephalopathy • Nutrition • Acidosis/ Renal Impairment • Early referral to Hepatology / discuss with Birmingham Liver Unit

  10. Mrs W • 48 year old ♀ admitted from a surgical clinic with jaundice and unwell • Unwell for 6 wks after holiday in Mexico • Hx of xs alcohol 30u/wk • No previous jaundice • USS normal size liver and spleen – biliary tree normal

  11. Jaundice Drowsy Agitated/Irritable Doesn’t obey commands No stigmata of CLD Asterixis OE No spleen No ascites

  12. U&E normal ALP 107 ALT 736 Bili 363 Alb 24 FBC Normal INR 3.7 Mrs W

  13. Drugs Paracetamol (UK) INH Halothane Ecstacy Viral Hepatitis A Hepatitis B Hepatitis E Non-A Non-B Wilsons Disease Autoimmune Hepatitis Reye’s Syndrome Cardiovascular Ischaemic hepatitis Budd Chiari Acute Fatty Liver of Pregnancy Causes of Acute Liver Failure

  14. Encephalopathy • Grade 1 • Constructional apraxia • Poor memory – number connection test • Agitation/ irritability • Reversed sleep pattern • Grade 2 • Lethargy, disorientation • Asterixis • Grade 3 • Drowsy, reduced conscious level • Grade 4 • Coma

  15. Cirrhosis Expanded Portal Tracts (Blue)

  16. Signs of Chronic Liver Disease • None • Asterixis/Flap • Relative hypotension • Oedema • Jaundice/No jaundice • Large/Small liver • Splenomegaly • Gynecomastia • Testicular atrophy-loss of secondary sexual characteristics • Impotence

  17. Decompensation in Cirrhosis Means the development of- Ascites Hepatic Encephalopathy Portal hypertension (variceal haemorrhage)

  18. Decompensation in Cirrhosis Means the development of- Ascites Hepatic Encephalopathy Portal hypertension (variceal haemorrhage)

  19. The Development of Ascites 50% of compensated cirrhotics develop ascites over 10yrs 50% of cirrhotics with ascites will die within 2 yrs (50% 2yr rule for OLTx assessment)

  20. NaCl The Development of Ascites Peripheral arterial dilatation Reduced effective blood volume Activation of renin-angiotensin-aldosterone system Sympathetic nervous system ADH Na retention & Water retention Ascites and Oedema Low urinary Na Dilutional hyponatraemia Plasma volume expansion Ascites Schrier et al Hepatol 1988

  21. General Management Ascites and Oedema • Salt restriction • Diuretics spironolactone frusemide • Water restriction if sodium < 125 mmol • Paracentesis diagnostic (SBP, tumour) therapeutic (20% Alb) • DAILY WEIGHTS!

  22. Decompensation in Cirrhosis Means the development of- Ascites Hepatic Encephalopathy Portal hypertension (variceal haemorrhage)

  23. Causes of Encephalopathy INCREASED AMMONIAGENESIS Increased substrate (protein) for ammoniagenesis • Increased protein intake • Gastrointestinal bleeding • Constipation • Dehydration Increased substrate (urea) for ammoniagenesis • Renal failure Increasedcatabolism of protein • Infection • Hypokalemia • Sepsis

  24. Causes of Encephalopathy DECREASED HEPATOCELLULAR FUNCTION • Worsened intrinsic liver disease • Hypoxia • Anaemia • Development of hepatocellular carcinoma • Dehydration • Hypotension • Sepsis • Drug toxicity • Superimposed viral hepatitis

  25. INCREASED PORTOCAVAL SHUNTING Portal vein thrombosis Transjugular intrahepatic portosystemic shunt formation Surgical shunt formation Spontaneous shunt formation PSYCHOACTIVE DRUG USE Benzodiazepines Ethanol Antiemetics Antihistamines Others Causes of Encephalopathy

  26. General Management Encephalopathy Minimize effects of liver disease Treat precipitants • sepsis • GI bleed • medications (over-diuresis) Avoid sedatives, hypnotics, opiates Lactulose to ensure BO 2x/day Metronidazole/ neomycin

  27. Decompensation in Cirrhosis Means the development of- Ascites Hepatic Encephalopathy Portal hypertension (variceal haemorrhage)

  28. Portal Circulation

  29. Oesophageal varices

  30. Management of Bleeding Varices • Prevention • Prophylactic Antibiotics • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin • Balloon Tamponade • TIPS

  31. Management of Bleeding Varices • Prevention • Prophylactic Antibiotics • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin • Balloon Tamponade • TIPS

  32. Fluid Management • Crystalloid • Colloid • Blood • Platelets • FFP • Vitamin K

  33. Management of Bleeding Varices • Prevention • Prophylactic Antibiotics • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin • Balloon Tamponade • TIPS

  34. Oesophageal varices

  35. Bleeding Gastric Varices

  36. Variceal Bander

  37. Variceal Band Ligation

  38. Management of Bleeding Varices • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin 2mg qds i.v • Balloon Tamponade • TIPS

  39. Management of Bleeding Varices • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin • Balloon Tamponade • TIPS

  40. Sengstaken-Blakemore Tube

  41. Complication of SBT

  42. Management of Bleeding Varices • Resuscitation • Endoscopy - Band Ligation Sclerotherapy • Pharmacotherapy- Terlipressin • Balloon Tamponade • TIPS

  43. The End “All right, let's not panic. I'll make the money by selling one of my livers. I can get by with one “ Doh!
