Noninvasive scores for the prediction of esophageal varices and risk stratification in patients with cirrhosis

Figure 1 Proposed algorithm for noninvasive esophageal variceal assessment to risk stratify patients using the EVendo score¹. Patients with known (biopsy-proven) or suspected cirrhosis. Excluded from the original study were patients who: (1) Had a prior upper endoscopy (EGD) for esophageal variceal screening, surveillance, or treatment; (2) Had a prior EGD that incidentally revealed esophageal varices; (3) Had noncirrhotic etiologies for portal hypertension; (4) Were on dialysis; or (5) Were on anticoagulants that would affect international normalized ratio. Online calculator and additional guidelines available here: https://www.mdcalc.com/evendo-score-esophageal-varices. ¹Other noninvasive scores exist and may be used, as shown in Tables 1 and 2; EVendo score selected and shown here based on it having the highest sensitivity, negative predictive value, and EGDs saved, though it has not yet been validated outside of the United States. EGD: Endoscopy; EV: Esophageal varices.
