Virtual Versus Dye-based Chromoendoscopy in Inflammatory Bowel Disease Surveillance Colonoscopy

"High-Definition Virtual Chromoendoscopy (HD-VCE):~Surveillance colonoscopy using high-definition virtual chromoendoscopy enhances mucosal visualization through advanced imaging filters integrated into the colonoscope. This dye-free technique improves detection of dysplasia by increasing contrast and highlighting subtle mucosal patterns during withdrawal. HD-VCE reduces procedure time and eliminates risks related to dye application, offering a practical alternative to dye-based methods. Its efficacy in IBD surveillance requires further validation."

"High-Definition Dye-Based Chromoendoscopy (HD-DCE):~Surveillance colonoscopy using high-definition dye-based chromoendoscopy involves segmental application of indigo carmine dye via a spray catheter. The dye enhances mucosal surface patterns, aiding dysplasia detection. HD-DCE is currently considered a gold standard in IBD surveillance due to superior dysplasia detection rates."
