EVendo_Score_for_Esophageal_Varices v.1
EVendo Score for Esophageal Varices predicts presence and size of esophageal varices before screening endoscopy.
To predict presence and size of esophageal varices before screening endoscopy.
Use in patients >18 years of age with known or suspected cirrhosis. Formula EVendo Score: A = (8.5 x INR) + (AST, U/L / 35) B = (Platelet count, x 10³/µL / 150) + (BUN, mg/dL / 20) + (Hemoglobin, g/dL / 15) EVendo Score = (A / B) + 1 (if ascites present) Interpretation: EVendo Score Probability of finding varices* Recommendation ≤3.90 <5%** Expectant management >3.90 ≥5% Endoscopy
Do not use in patients with overt GI bleeding or with history of acute variceal hemorrhage.
