La cromoendoscopia virtual i-Scan y su aplicación en la detección y caracterización de los pólipos de colon

Henry Royero Gutiérrez

Resumen


La limitación de la colonoscopia con luz blanca respecto a la omisión de neoplasias avanzadas en un 6%, y de adenomas hasta un 25%, ha motivado el desarrollo de técnicas como la cromoendoscopia virtual, entre ellas el sistema i-Scan, para detectar un mayor número de pólipos, como estrategia de prevención del cáncer de colon. Con esta revisión se resume la aplicación actual de este método en la detección de adenomas y su caracterización. Se ha encontrado que este nuevo sistema es una alternativa posible en nuestro medio a las ya existentes y mejor conocidas, como el NBI y FICE.
