Abstract
Opinion statementElectronic chromoendoscopy (EC) is an equipment-based technology which could be easily activated by push of a button. There are four EC techniques available for use at present: narrow band imaging (NBI), i-Scan, flexible spectral chromoendoscopy and blue laser imaging. Out of the four techniques, NBI has been extensively evaluated for the detection and characterization of dysplasia in colonic polyps and dysplasia associated with inflammatory bowel disease. In this review, we will focus on the new developments and applications of EC.
Highlights
Colorectal cancer (CRC) is one of the commonest causes of significant morbidity and mortality in the western world
Familial CRC and CRC associated with inflammatory bowel disease arise from dysplastic lesions which can be detected at colonoscopy
The second trial performed by Pohl et al involving 764 patients did not demonstrate an improvement in adenoma detection with flexible spectral imaging colour enhancement (FICE) compared to white light endoscopy (WLE) (236 and 271, p = 0.92) [20]
