What are the endoscopic grading criteria for esophageal varices and the recommended management for each grade?

Endoscopic Grading and Management of Esophageal Varices

All newly diagnosed cirrhotic patients should undergo screening upper endoscopy to grade esophageal varices, with management stratified by size: small varices (grade 1) receive nonselective beta-blockers, while medium/large varices (grades 2-3) receive either nonselective beta-blockers or endoscopic band ligation (EBL). 1, 2

Endoscopic Grading Systems

The most widely used classification divides esophageal varices into three grades based on size:

• Grade 1 (Small): Varices that flatten with insufflation, minimally elevated above the esophageal mucosa
• Grade 2 (Medium): Tortuous varices occupying less than one-third of the esophageal lumen, do not flatten with insufflation
• Grade 3 (Large): Large coil-shaped varices occupying more than one-third of the esophageal lumen

Additional high-risk stigmata include red wale marks (longitudinal dilated venules), cherry red spots, and diffuse erythema on the varix surface 3, 4. These endoscopic features predict higher bleeding risk independent of varix size.

Primary Prophylaxis (Prevention of First Bleed)

For Patients WITHOUT Varices or Small Varices (Grade 1)

• Nonselective beta-blockers (NSBBs) are NOT recommended for preventing varix development 1
• Repeat surveillance endoscopy every 2-3 years to monitor for progression 3

For Patients WITH Medium/Large Varices (Grades 2-3)

Choose ONE of the following options 1, 2:

1. Nonselective beta-blockers (preferred initial approach):

   • Carvedilol (preferred agent) or propranolol/nadolol
   • Titrate to maximum tolerated dose (target heart rate 55-60 bpm or 25% reduction from baseline)
   • Continue indefinitely

2. Endoscopic band ligation (EBL):

   • Reserved for patients with contraindications or intolerance to NSBBs
   • Repeat sessions every 2-4 weeks until variceal eradication (typically 2-4 sessions)
   • First surveillance endoscopy 1-3 months after eradication, then every 6-12 months 1
   • Do NOT combine EBL with sclerotherapy - no benefit and higher complication rates 1

Acute Variceal Hemorrhage Management

Immediate Resuscitation

• Maintain hemoglobin at 7-8 g/dL (restrictive transfusion strategy) 2
• Initiate vasoactive therapy IMMEDIATELY upon suspicion (before endoscopy):
  • Octreotide, somatostatin, or terlipressin
  • Continue for 3-5 days 1, 2

Antibiotic Prophylaxis (MANDATORY)

• Ceftriaxone 1g IV daily for up to 7 days (preferred in advanced cirrhosis or quinolone-resistant areas) 2
• Alternative: Norfloxacin 400mg PO BID or ciprofloxacin IV 1

Pre-Endoscopy Preparation

• Erythromycin 250mg IV given 30-120 minutes before endoscopy to improve visualization 2

Endoscopic Therapy (Within 12 Hours)

• EBL is the endoscopic treatment of choice for acute esophageal variceal bleeding 1, 2
• Sclerotherapy only if EBL unavailable or technically impossible
• For gastric varices (GOV2, IGV1): Cyanoacrylate injection is superior to EBL 1, 2

Salvage Therapy for Treatment Failure

• Pre-emptive TIPS within 72 hours (preferably 24 hours) for high-risk patients:
  • Child-Pugh C ≤13 OR
  • Child-Pugh B >7 with active bleeding at endoscopy despite vasoactive agents OR
  • HVPG >20 mmHg 2
• Balloon tamponade as bridge (maximum 24 hours) if uncontrolled bleeding 1

Secondary Prophylaxis (Prevention of Rebleeding)

Combination therapy is superior to monotherapy 1:

1. Nonselective beta-blockers (carvedilol or propranolol):

   • Titrate to maximum tolerated dose
   • Continue indefinitely

2. PLUS Endoscopic band ligation:

   • Repeat every 1-2 weeks until variceal obliteration
   • First surveillance at 1-3 months post-obliteration, then every 6-12 months 1, 2

For Refractory Cases

• TIPS indicated for recurrent bleeding despite combined pharmacological and endoscopic therapy 1
• Consider surgical shunt in Child-Pugh A patients at experienced centers 1

Critical Pitfalls to Avoid

• Never use sclerotherapy for secondary prophylaxis - inferior to EBL with more complications 1
• Never combine EBL with sclerotherapy - increases stricture risk without benefit 1
• Do not over-transfuse - target hemoglobin 7-8 g/dL, not higher 2
• Do not delay antibiotic prophylaxis - start immediately in any cirrhotic with GI bleeding 1, 2
• Proton pump inhibitors (pantoprazole 40mg daily) reduce post-EBL ulcer size and may prevent post-procedure bleeding 1
