Magnifying chromoendoscopy or image enhanced endoscopy with magnification?

Abstract

This Editorial refers to the article by H. Ikematsu et al., p 265–273 of the issue DEN 34:2.

Precision endoscopy in colorectal polyps' characterization and planning of endoscopic therapy

“…Currently, magnification after crystal violet staining is considered the most accurate evaluation method. 79 However, crystal violet staining is burdened by some limitations. First, the longer procedural time represents a significant disadvantage.…”

“…Second, preparing the crystal violet is time-consuming. 79 Third, the technique involves applying a mucolytic agent on the polyp surface to facilitate absorption of the dye and pronase, the mucolytic agent used in Japan, is not available in Western countries. Finally, crystal violet has been found to have potential carcinogenic properties.…”

“…Finally, crystal violet has been found to have potential carcinogenic properties. 79 In recent years the importance of magnification chromoendoscopy, which can be more easily performed, has increased. As mentioned above, NBI is the most widely used IEE enriched with magnification.…”
