Light blue crest (blue fringe): endoscopic diagnosis of pathology

Abstract

I have been greatly interested in the meaningful data from Tahara et al. presented in response to our reported finding using magnifying narrow band imaging (NBI). The authors suggested that a finding of the light blue crest by magnifying NBI, especially in the gastric corpus, could be a good indicator of high risk for the development of gastric cancer. I think their data highlight two important points about endoscopic diagnosis of intestinal metaplasia in the stomach.
