Chromoendoscopy in Barrett's oesophagus: is cresyl violet the magic bullet?

2006

The endoscopic detection of Barrett’s epithelium remains challenging even for modern endoscopy. This is mainly due to the fact that Barrett’s epithelium is often patchy and can easily be overlooked by conventional endoscopy with random biopsies. Thus, chromoendoscopy and magnifying endoscopy were introduced to facilitate diagnosis of Barrett’s epithelium and Barrett’s associated neoplasias. Methylene blue-aided chromoendoscopy was firstly introduced by Canto et al. [1]. The authors could show that methylene blue selectively stains specialised columnar epithelium, which is pathognomonic for Barrett’s epithelium. In contrast, dysplastic areas revealed no or weaker staining due to changes in t…
