Resumen
El cáncer gástrico es una de las patologías más frecuentes mundialmente. Ecuador ocupa el quinto lugar de incidencia; en varones alcanza el 22,7/100.000 habitantes; y en mujeres 14,5; con una tasa de mortalidad del 11,6/10.000 habitantes. Avances tecnológicos, como la endoscopía con imágenes de banda angosta (NBI), que logra una alta definición de imágenes gracias a la aplicación de cromatografía electrónica y magnificación de imágenes, han sido desarrollados en búsqueda de diagnósticos oportunos. Su utilidad, frente al procedimiento convencional, es el objetivo de esta investigación de tipo correlacional, y diseño no experimental transversal. En el período comprendido de enero del 2011 a febrero del 2012, en el ION SOLCA “Dr. Juan Tanca Marengo”, se estudiaron un total de 100pacientes; 50 de ellos con NBI y 50 con endoscopia convencional, la edad promedio fue de 55años. Los resultados obtenidos con endoscopía NBI, revelan una clara ventaja en el diagnóstico de metaplasia/displasia: sensibilidad 95,74%, especificidad: 66,67%, VPP: 97,85%, VPN: 50% y un índice de probabilidad diagnóstica del 96%, en comparación al diagnóstico logrado con endoscopía convencional.
The gastric cancer is one of the most frequent pathologies world-wide. Ecuador occupies the fifth place of incidence; in men it reaches the 22.7/100,000 inhabitants; and in women 14, 5; with a rate of mortality of the 11.6/10,000 inhabitants. Technological advances, like endoscopy with images of narrow band (NBI) that obtains a high resolution of images thanks to the application of electronic chromatography and magnification of images have been developed in search of opportune diagnoses. Its utility, as opposed to the conventional procedure, is the objective of this investigation of corelational type, and cross-sectional nonexperimental design. In the included/understood period of January of the 2011 to February of the 2012, in ION SOLCA “Dr. Juan Tanca Marengo”, a total of 100pacientes studied; 50 of them with NBI and 50 with conventional endoscopy, the age average was of 55años. The results obtained with endoscopy NBI, reveal a clear advantage in the diagnosis of metaplasia/dysplasia: sensitivity 95.74%, specificity: 66.67%, VPP: 97.85%, VPN: 50% and a probability index diagnose of 92%, in comparison to the diagnosis obtained with conventional endoscopy l.
