Chromoendoscopy in Madrid – dysplasia screening and digestive cancer prevention
Real-world precision to detect subtle lesions in Barrett’s, stomach and colon—especially in high-risk surveillance.
What is chromoendoscopy—and why does it matter?
Digestive chromoendoscopy is an endoscopic technique that uses dyes (e.g., indigo carmine or methylene blue) to enhance mucosal visualisation and improve detection of neoplastic lesions—especially in inflammatory bowel disease (IBD) surveillance and high-risk colonoscopy. [Source](https://pubmed.ncbi.nlm.nih.gov/38038351/)
Plain and simple: when a lesion is flat, subtle, or “hiding in plain sight”, contrast matters. A high-quality examination—proper cleaning, systematic inspection, and targeted dye application when appropriate—reduces uncertainty.
Chromoendoscopy focused on what truly matters
Four scenarios where chromoendoscopy adds clinical value: Barrett’s, stomach, colon, and IBD. Less “let’s see what we find”—more strategy.
Dysplasia screening in Barrett’s esophagus
The goal is early detection—before progression to cancer. The ACG 2022 guideline updates recommendations for diagnosis, surveillance, and management, highlighting the importance of a high-quality endoscopic examination.

The AGA also provides a dedicated surveillance guideline (2025) reinforcing structured, high-quality imaging strategies. [Source](https://www.gastrojournal.org/article/S0016-5085(25)06013-5/fulltext)

In the stomach, dye application can help highlight mucosal patterns and define suspicious areas in patients with risk factors or prior findings. It’s the difference between “looks normal” and “there’s a subtle area worth targeted biopsies.”

Chromoendoscopy: clear answers
Common questions, answered with one rule: useful, clear, no fluff.
It is an endoscopic technique that applies dyes (e.g., indigo carmine or methylene blue) to enhance mucosal visualisation and improve detection of subtle lesions—particularly in high-risk surveillance such as IBD. [Source](https://pubmed.ncbi.nlm.nih.gov/38038351/)
It refers to dye application during gastroscopy to highlight mucosal patterns and guide detection of subtle lesions or targeted biopsies in patients with risk factors or prior relevant findings.
It is the use of dyes during colonoscopy to increase contrast and improve detection of adenomas and flat lesions. Evidence supports improvements in colorectal neoplasia detection and quality metrics. [Source](https://pubmed.ncbi.nlm.nih.gov/35588768/)
The Cochrane review also supports improved neoplasia detection versus conventional endoscopy. [Source](https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD006439.pub4/full)
