Su principal complicación fue la hipertensión portal, manifestada por várices esofágicas (VE) que afectan a 30% de los pacientes.  OBJETIVO: utilizar la correlación del índice plaqueta/bazo (IPB) con el grado de várices esofágicas como método diagnóstico no invasivo y de decisión terapéutica.  MATERIAL Y MÉTODO: estudio observacional, analítico, transversal y retrospectivo, en el que se recolectaron datos de pacientes con diagnóstico de insuficiencia hepática, atendidos en el servicio de Medicina Interna del Hospital Central Norte de Petróleos Mexicanos, entre enero de 2010 y abril de 2016; se calcularon puntos de corte para conocer el grado de asociación del IPB con el grado de várices esofágicas; el patrón de referencia fue la endoscopia digestiva alta.  RESULTADOS: se encontró un nivel de significación con valor p de 0.005 y Rho de Spearman de -0.425 que traduce una correlación estadísticamente significativa entre las variables en correlación con la escala de Dagradi y nivel de significación con valor p de 0.001 y Rho de Spearman de -0.492 en correlación con la escala de Baveno. Asimismo, para la escala de Baveno un IPB mayor a 0.700 se correlacionó con várices esofágicas pequeñas, en tanto que un IPB menor a 0.700 se correlacionó con várices esofágicas grandes.  CONCLUSIONES: esta correlación puede ser un método no invasivo útil que permite establecer prioridad en cuanto al abordaje diagnóstico y discernir entre iniciar tratamiento farmacológico o realizar un procedimiento endoscópico.]]></p></abstract>

Its main complication was portal hypertension, manifested by esophageal varices (EV) occurring in 30% of patients.  OBJECTIVE: To use the correlation of platelet/spleen index (PSI) with the degree of EV as a noninvasive diagnostic method and therapeutic decision.  MATERIAL AND METHOD: An observational, analytical, cross-sectional and retrospective study was done in which data were collected from patients with chronic liver failure assisted at the Department of Internal Medicine of North Central Hospital Pemex, Mexico City, from January 2010 to April 2016. Cutpoints were calculated to determine the degree of association between PSI with the degree of EV; using the upper gastrointestinal endoscopy as the gold standard.  RESULTS: We found a significance level with p-value of 0.005 and -0.425 Spearman Rho, defaming a statistically significant correlation between the variables in correlation to Dagradi Scale and a level of significance with p-value of 0.001 and -0.492 Spearman Rho in correlation to Baveno Scale. For Baveno scale it was observed that a PSI higher than 0.700 correlated with small EV, while a PSI lesser than 0.700 PSI correlated with large EV.  CONCLUSIONS: This correlation can be a non-invasive useful method which allows to set priority in regard to diagnostic approach and to dis cern between starting drug treatment or doing endoscopic procedure.]]></p></abstract>
