chromoendoscopy

chromoendoscopy

The topical application of stains or dyes during endoscopy as a means of enhancing mucosal changes and to provide a better “target” for diagnostic biopsies.

chromoendoscopy

(kro?mo-en-dos'ko-pe) [ chromo- + endoscopy]
The use of tissue-staining dyes, such as methylene blue, to aid in the identification of abnormal or precancerous lesions seen inside the body during endoscopy.
Synonym: chromoscopy

The development of chromoendoscopy has added another dimension to the evolving market of endoscopy.
With the advent of chromoendoscopy and other newer endoscopic technology, better and more efficient ways for screening dysplasia are on the horizon.
Endoscopic evaluation with or without chromoendoscopy and random biopsies can diagnose a subset of patients in the early stages of ESCC, but the invasiveness of these diagnostic procedures and the potential for sampling error with random endoscopic biopsy limit their effectiveness.
With numerous color clinical photographs and other illustrations, they describe the settings and staff, including disinfection and the role of the pediatric endoscopy nurse, equipment, including image resolution and troubleshooting, patient preparation, including pediatric-monitored sedation and anesthesia, postsedation care and specific sedation techniques, diagnostic upper endoscopy techniques including push endoscopy and jejunoscopy, therapeutic upper gastrointestinal endoscopy, pediatric colonoscopy, polypectomy, chromoendoscopy, and wireless capsule endoscopy for children, including information on pacemaker safety and bowel preparations.
cap-assisted colonoscopy, wide-angle colonoscopy, and bioendoscopic techniques such as chromoendoscopy.
The new HD+ technology in combination with virtual chromoendoscopy therefore considerably enhances our diagnostic and therapeutic endoscopic options"
Chromoendoscopy uses only magnification of reflected light from surfaces, with the methylene blue or cresyl violet staining helping to disclose surface changes characteristic of neoplasia.
We're beginning to move toward chromoendoscopy, where we spray the colon with a contrast material that picks up dysplasia a little bit better," he added.
In particular, the updated recommendations reflect a shift to using chromoendoscopy for patients with IBD during screening and surveillance in order to better visualize the tissue.
Glandular dysplasia is often undetectable by conventional endoscopic visualization, thereby necessitating the use of random 4-quadrant mucosal biopsies in surveillance protocols or enhancing techniques (eg, acetic acid-guided biopsies, magnification chromoendoscopy with indigo carmine staining, high-resolution magnification with narrow-band imaging).
The study he reported tested two other new methods for improving endoscopy sensitivity: indigo carmine chromoendoscopy (ICC), and narrow-band imaging (NBI).
Endoscopic identification of early lesions has greatly improved with the introduction of new endoscopic techniques such as chromoendoscopy, confocal endomicroscopy, and narrow-band imaging.
