Abstract

Colorectal cancer (CRC) is a major health problem. An improvement in survival has been demonstrated by performing screening colonoscopies and removing their precursor lesions, the polyps. However, colonoscopy is not infallible and multiple strategies have been proposed aimed at improving the quality of it. This review describes the endoscopic systems available to improve the detection and characterization of polyps, the different classifications for histological prediction and the current indications of advanced endoscopic diagnostic techniques.

Resumen

El cáncer colorrectal (CCR) constituye un problema de salud importante. Se ha demostrado una mejoría de la supervivencia mediante la realización de colonoscopias de cribado y la extirpación de sus lesiones precursoras, los pólipos. Sin embargo, la colonoscopia no es infalible y se han propuesto múltiples estrategias dirigidas a mejorar la calidad de la misma. En esta revisión se describen los sistemas endoscópicos de que disponemos para mejorar la detección y caracterización de los pólipos, las diferentes clasificaciones utilizadas para la predicción histológica y las indicaciones actuales de las técnicas de diagnóstico endoscópico avanzado.
