A 55-year-old man with cirrhosis presents with hematemesis. Endoscopy reveals bleeding esophageal varices. Which feature best distinguishes variceal bleeding from peptic ulcer disease as the source of upper GI hemorrhage?

## Distinguishing Variceal from Peptic Ulcer Bleeding ### Key Clinical Discriminator **High-Yield:** Variceal bleeding typically presents with **abrupt onset of massive hemorrhage** with rapid hemodynamic compromise, whereas peptic ulcer bleeding is usually more gradual and often preceded by dyspepsia. ### Comparative Features | Feature | Variceal Bleeding | Peptic Ulcer Bleeding | |---------|-------------------|----------------------| | **Onset** | Sudden, massive | Gradual, often preceded by pain | | **Hemodynamic impact** | Rapid shock, severe anemia | Variable, may be slow | | **Prodromal symptoms** | None (unless known varices) | Chronic epigastric pain | | **Endoscopic finding** | Varix with or without clot | Ulcer base with visible vessel/clot | | **Recurrence rate** | High (60% without treatment) | Lower (5–10% with PPI) | | **Mortality** | 30–50% per bleed | <5% with modern therapy | ### Why This Discriminator Works **Key Point:** Variceal rupture causes **uncontrolled, rapid blood loss** because the varices lack the protective fibrin-platelet plug that forms in ulcer bases. The sudden massive bleed with hemodynamic collapse is pathognomonic for variceal hemorrhage. **Clinical Pearl:** A patient with known cirrhosis who suddenly becomes hypotensive and tachycardic with hematemesis should be assumed to have variceal bleeding until proven otherwise — this warrants immediate resuscitation, blood products, and variceal-specific therapy (octreotide, band ligation). ### Why Other Options Are Incorrect - **Melena + hematemesis:** Both variceal and ulcer bleeding can present this way; not discriminatory. - **Chronic epigastric pain history:** This is a feature of peptic ulcer disease, not a discriminator *between* the two. - **Visible vessel/clot at base:** This is an endoscopic finding in peptic ulcers; varices do not have an ulcer base, so this finding excludes variceal bleeding but does not distinguish it as the primary discriminator in the clinical presentation.
