Chromoendoscopy is inexpensive, safe, and relatively easy to perform, although the method is not standardized for several stains and the staining patterns are subject to observer interpretation. There is a need to build consensus on the staining techniques and terminology of the mucosal patterns for most applications, in addition to proving efficacy and reproducibility in high-quality, randomized, controlled trials before chromoendoscopy can be incorporated into routine clinical practice. The cost-effectiveness of tissue staining for various GI conditions has not been established, and its stance relative to commercially available, competing, and less cumbersome "chromoendoscopy without dye" techniques, such as narrow-band imaging,107 remains to be seen.
