Abstract
Objective To compare the morphology and histology about the chronic atrophic gastritis (CAG) narrow-band imaging (NBI),in order to improve the rate of final diagnosis.Methods The clinical data of 100 CAG patients who diagnosed by NBI from September 2011 to December 2012 were analyzed retrospectively.The morphological diagnosis by NBI and histodiagnosis by endoscopy were compared.Results In 100 patients,94 patients were diagnosed by histodiagnosis among whom 28 patients were with mild dysplasia,8 patients were with moderate dysplasia,7 patients were with severe dysplasia.In the NBI mode,gastric pits were divided into 6 kinds of types,dysplasia mainly expressed for Ⅳ and Ⅴ 1 type.In 7 severe dysplasia patients,2 patients of microvascular morphology were regular,the others were anomalism,and found neovascularization.Conclusions Endoscopic NBI technology has the advantage of simple operation,and can clearly observe the gastric pit and microvascular morphology after amplification.It can help to improve the accuracy rate of CAG and dysplasia targeted biopsy. Key words: Gastritis, atrophic; Histology; Morphology; Narrow-band imaging
