OBJECTIVE: To determine the area under the curve of Thrombocytopenia, the aspartate aminotransferase index/platelet count, and the Child Pugh scale in predicting esophageal varices in cirrhotic patients. MATERIAL AND METHODS: A diagnostic test study was conducted in 113 patients diagnosed with hepatic cirrhosis at the Victor Lazarte Echegaray Hospital during the period January – December 2017. Sensitivity, specificity, predictive values were calculated; as well as the cutting points of such tests. The area was applied under the curve, the Chi -square test and the positive and negative likelihood ratio. RESULTS: Of the 113 patients included in the study, the frequency of esophageal varicose veins in cirrhotic patients was 73 (65%) and those who did not present varicose veins were 40 (35%). The cutoff point of thrombocytopenia as a predictor of esophageal varicose veins in cirrhotic patients was < 150000; With a sensitivity, specificity, positive and negative predictive value of 69.86%, 32.5%, 65.38%, 37.14% respectively, the scale of Child Pugh was also evaluated as a predictor, having as cutting points for B and C ≥ 7; With a sensitivity, specificity, positive and negative predictive value of 46.58%, 80%, 80.95%, 45.07%, respectively. Finally, the aspartate aminotransferase index/Platelet count was found, with a cut-off point ≥ 0039%, with a sensitivity, specificity, positive and negative predictive value of 76.71%, 52.5%, 74.67%, 55.26% respectively. In evaluating the diagnostic tests it was concluded that each one presents statistical significance (p < 0.05), and that within them, the scale of Child Pugh is the most statistically significant (P = 0.003%) CONCLUSION: Thrombocytopenia, the aspartate aminotransferase index/platelet count and the Child Pugh scale have validity as predictors of esophageal varicose veins in cirrhotic patients.
