| [ Summary ] | Many authors have reported on the usefulness of endoscopic diagnosis for colorectal lesion since the introduction of Narrow Band Imaging (NBI) in 2006, which provides image enhancement observation. On the other hand, various problems such as darkness of images and presence of many NBI classifications were also found. The second generation NBI system, the EVIS LUCERA ELITE by Olympus Medical Systems, Tokyo, Japan was implemented in 2012. This system provides brighter images. It has also provided higher resolution, and wide angle observation when using an endoscope of the 290 series. It was found that we could diagnose with high levels of confidence by using a magnifying endoscope not only for depth diagnosis but also for qualitative diagnosis. Therefore magnifying endoscopes are necessary for NBI diagnosis. Furthermore, JNET colorectal magnifying NBI classification which is a united classification have been proposed. Improvements in NBI diagnosis is expected. | |
