High resolution chromo-endoscopy: An affordable and accurate non-biopsy technique for predicting histology of colorectal polyps

Characterization of colonic polyps at conventional (nonmagnifying) colonoscopy after spraying with 0.2 % indigo carmine dye

“…The correct identification of non−neoplastic polyps at endoscopy saves time, reduces cost, and minimizes the risk of complications associated with polypectomy. Dye spraying with magnification colonoscopy has been proposed as the best way to identify neo− plastic lesions at colonoscopy [9,13,15,22,23]. However, magni− fying colonoscopes are more delicate, more expensive, and more cumbersome to use [9].…”

Optical diagnosis of colorectal neoplasia: A Western perspective

“…Methylene blue and crystal violet, however, are absorptive dyes that preferentially stain the mucosal surface, and highlight the unique pit pattern of mucosal lesions . There are only a few Western studies that have examined the use of chromocolonoscopy for the purpose of differentiating between neoplastic and non‐neoplastic polyps . In the West, chromocolonoscopy has not been routinely adopted during colonoscopy because of perceptions that this technique is cumbersome, time‐consuming, difficult to learn and impractical .…”

“…[9][10][11][12] There are only a few Western studies that have examined the use of chromocolonoscopy for the purpose of differentiating between neoplastic and non-neoplastic polyps. [13][14][15][16][17] In the West, chromocolonoscopy has not been routinely adopted during colonoscopy because of perceptions that this technique is cumbersome, time-consuming, difficult to learn and impractical. 18 However, Western gastrointestinal societies have endorsed the use of chromocolonoscopy for inflammatory bowel disease surveillance, Lynch syndrome and serrated polyposis syndrome.…”
