RESUMEN
La cromoendoscopia virtual computarizada es la técnica de estimación espectral basada en el procesamiento aritmética de imágenes capturadas por el video endoscopio. Este estudio incluye 247 pacientes a quienes se le realizó Colonoscopia en el período comprendido entre Abril 2007 y Mayo 2009 (83/33,5 % hombres, 164/66,5 % mujeres). La comparación fue realizada entre la visualización endoscópica con FICE, las imágenes grabadas y el diagnóstico histológico final realizado mediante biopsias, polipectomia o mucosectomia evaluados por dos patólogos expertas en patología gastrointestinal. La aplicación de esta nueva técnica combinada con magnificación constituye un área prometedora en la descripción de cambios patológicos mínimos de la mucosa y microvasculares. Permite incrementar la correlación entre las imágenes endoscópicas y los resultados histopatologicos.
ABSTRACT
The computed virtual chromoendoscopy imaging technique is based on narrowing the bandwidth of the conventional endoscopic image arithmetically, using spectral estimation technology. This study includes 247 consecutive patients (83/33.5% males, 164/66.5% females) who had a colonoscopy performed between April 2007 and May 2009. A comparison was made between direct visualization with FICE and recorded images and the fi nal diagnosis made by biopsy, polipectomy or endoscopic mucosal resection. The sampling was evaluated by two experts GI pathologist. The application of this new technology combined with high resolution endoscopy has promising areas of development in the description of pathologic mucosal changes and microvessels. This advanced technology allows an increased correlation between the images processed and the histological results.
