Introducción: Al ser el esófago de Barrett la única lesión precursora conocida para el desarrollo del Adenocarcinoma de esófago, es importante en su diagnóstico establecer si es Neoplásico o No Neoplásico. Objetivo: El objetivo fue evaluar la eficiencia de la Cromoendoscopia Virtual utilizando Blue Laser Imaging (BLI), para el diagnóstico endoscópico de Esófago de Barrett Neoplásico y no Neoplásico. Materiales y Métodos: Estudio observacional prospectivo no probabilístico de tipo intencional, se incluyeron 91 pacientes, los hallazgos endoscópicos a buscar fueron las alteraciones morfológicas endoscópicas que muestran los descriptores predictores de la Clasificación BLINC, usando Cromoendoscopia Virtual basada en BLI, para identificar el Esófago de Barrett Neoplásico o No Neoplásico, con su confirmación histopatológica. Resultados: 91 pacientes, el promedio de edad 57 años (DE = 13.4), 55 (60,44%) mujeres y 35 (39,56%) hombres. Esófago de Barrett Neoplásico: 16 pacientes con diagnóstico endoscópico Sensibilidad: 93.75%, Especificidad: 96%, VPP: 84%, VPN: 89%. Kappa: 0.85, p<0.001. Esófago de Barrett No Neoplásico: 75 pacientes con diagnostico endoscópico Sensibilidad: 95.50%. Especificidad: 93%, VPP: 98%, VPN: 85%. Kappa: 0,86, p<0.001. Conclusión: La alta sensibilidad obtenida es un fuerte indicador del desempeño de la Cromoendoscopia Virtual utilizando BLI, para ser usada eficazmente en el diagnóstico de Esófago de Barrett Neoplásico o No Neoplásico.
