[Confocal laser endo-microscopy and confirming endoscopic procedures in the diagnosis of Barrett's esophagus].

Barrett's esophagus is known to be a premalignant condition being one of the most dangerous complications of gastroesophageal reflux disease. Well-timed revealing of intestinal metaplasia and dysplasia gives the opportunity of adequate treatment and as a result prophylaxis of esophageal adenocarcinoma. The endoscopic method is leading in diagnostics of Barrett's esophagus. This article presents the comparative analyses of chromoendoscopy, narrow-band imaging and confocal laser endomicroscopy in diagnosis of the type of metaplasia in Barrett's esophagus.
