Resumen breve

Chromoendoscopy (indigo carmine or acetic acid) and Narrow Band Imaging (NBI) could make accurate evaluation in predicting of invasive depth of colorectal neoplasia. NBI could be the first choice.

Descripción detallada

To compare the diagnostic accuracy of chromoendoscopy indigo carmine or acetic acid and NBI for differentiating neoplastic from non-neoplastic colorectal lesions, differentiating adenomas from carcinomas, and differentiating early carcinomas from invasive ones.

Included colorectal lesions consecutively distribute in a 1:1 ratio to 2 groups.
