Abstract:
Background:Currently,chronic atrophic gastritis( CAG)is diagnosed by endoscopy combined with pathological examination. Narrow-band imaging magnifying endoscopy( NBI-ME)has been widely applied to diagnose CAG. However, it is a issue how to optimize the examination technology. Aims:To investigate the clinical value of NBI-ME in diagnosis of CAG,intestinal metaplasia and intraepithelial neoplasia. Methods:One hundred CAG patients reexamined gastroscopy were enrolled,sequential examination was performd,i. e. the extent of disease was observed under convention white light endoscopy( C-WLI ) followed by NBI-ME mode to observe locally,morphological changes of gastric mucosa pit was analyzed,endoscopic findings and histological results was compared. Results:Sensitivity of sequential examination for the diagnosis of CAG was 89. 7%,specificity was 63. 3%;sensitivity and specificity for the diagnosis of intestinal metaplasia were 89. 4%,89. 3%,respectively,for intraepithelial neoplasia were 84. 2%,95. 9%,respectively. Conclusions:Sequential examination can significantly improve the diagnostic accuracies of CAG,intestinal metaplasia and intraepithelial neoplasia,and effectively guide targeted biopsy,and easily to operate.
