PWE-216 Diagnostic accuracy for detection of dysplasia in Barrett's oesophagus using narrow band imaging with magnification improves after a short training session in those with prior exposure to NBI but not in novices

Abstract

IntroductionNarrow band imaging (NBI) with magnification (NBI-zoom) has been shown to be highly sensitive and specific in identifying dysplasia in Barrett's oeosphagus (BO). These studies have been done using experts...
