Core Tip
Core tip: Several studies examined the feasibility of optical diagnosis of colorectal polyps using chromoendoscopy, either dye-based or digital techniques, while only a few studies examined the performances using the high-definition (HD) i-scan technology. In addition, experience on prediction of polyp histology using HD i-scan has been reported in an expert setting only, was based on various classification criteria, and paid only a limited attention to the impact of training. In the current study, at our university hospital, we investigated the effect of training on the diagnostic performances of endoscopists with varying levels of experience. We found that, after a short didactic training session, all endoscopists, trainees as well as gastroenterologists, can predict polyp histology with a mean accuracy of 84%.
