EBM Oesophagogastric Varices

Epidemiology

  • 5-12% upper G1 bleeds.
  • 50% cirrhosis patients have varices, up to 85% in Child-Pugh C patients.
  • 25-35% of patients with chronic liver disease will have a variceal bleed, which accounts for 50-90% of bleeding episodes in those patients.
  • Mortality of a first bleed 15-30%, with rebleeding in 30-60% after banding / sclerotherapy (highest risk in first 10 days), and a 32-80% 1-year mortality.

Management

Endoscopic:

  • Banding ligation.  Lower rebleeding, mortality and complication rate than sclerotherapy.
  • Sclerotherapy.  Rebleed in 20-50%; higher complication rate.  May be followed by propranolol.
  • Tissue adhesive eg. cyanoacrylate or bucrylate especially for gastric varices; intravariceal thrombin.

Vasoactive drugs:

  • In absence of or awaiting (ie. during transfer); or as adjunct to (ie. octreotide) endoscopy.
    • Octreotide 50 μg, then 25-50 μg/hr IV. Long-acting somatostatin analogue. 80% success with decrease in bleeding, borderline mortality benefit. Continue for 24-48 hours.
    • Somatostatin.  More expensive, shorter half-life.
    • Terlipressin (Glypressin) 2 mg 6-hrly or vasopressin +/- GTN, to reduce portal pressure and deal with coronary ischaemia.
    • [Beta blocker (propanolol /nadolol) +/- isosorbide. Used for primary and secondary prophylaxis of bleeding, but not in acute bleeding].

Antibiotics:

  • Norfloxacin 400 mg orally bd or ciprofloxacin IV at same dose, preferably before endoscopy, in any cirrhotic patient with an upper GI bleed. Ceftriaxone 1 g IV an alternative.

Balloon tamponade (Sengstaken-Blakemore tube):

  • Temporising procedure only. Up to 25% complications including death from aspiration, migration and or perforation, 50% rebleed. Need airway protection by endotracheal intubation.

Variceal decompression:

  • Transjugular intrahepatic portosystemic shunt (TIPS). May be preferred to surgery in refractory or rebleed patients, possibly preceded by transjugular variceal embolisation. Also when liver transplantation being considered.
  • Surgery. Emergency direct portacaval shunt (EPCS) or oesophageal transection.
  • Either technique reduces re-bleed risk and mortality, with little increase in hepatic encephalopathy risk. However, 30-day mortality up to 80%.
