Virtual Chromoendoscopy for Real-Time Assessment of Colorectal Polyps’ Histology: is There Any Predictor of Diagnostic Performance?

Aims Virtual chromoendoscopy (VC) such as Narrow band imaging (NBI) or Flexible spectral imaging color enhancement (FICE) offer better resolution of the pit pattern and the vascular pattern of colorectal polyps, which allows real-time assessment of these lesions’ histology. The aim of this study was to assess virtual chromoendosctopy’s performance in predicting colorectal polyps’ histology and to determine predictors of diagnostic accuracy.
