Abstract：Objective:To explore the value of narrow-band imaging magnifying endoscopy(NBI-ME)in the di-agnosis of gastric intestinal metaplasia(GIM).Methods:A total of 251 patients who underwent NBI-ME gastroscopy in traditional chinese medicine hospital of wuhu from January 1,2023 to March 10,2024 were selected.The examination sequence was white light endoscopy first,and then NBI-ME was performed.Under NBI-ME,the light blue crest(LBC)of gastric antrum biggish curvature,gastric antrum minor curvature,gastric angle,gastric body biggish curvature and gastric body minor curvature were recorded respectively,and compared with pathological examination results.Re-sults:The sensitivity of LBC under NBI-ME for diagnosing GIM was 85.29％,the specificity was 86.58％,the posi-tive predictive value was 81.31％,the negative predictive value was 89.58％,the Youden index was 71.87％.The ken-dall's tau-b analysis showed a significant positive correlation between operative link on gastritis assessment based on intestinal metaplasia(OLGIM)stage and LBC endoscopic grading,with a correlation coefficient of 0.729.Conclusion:NBI-ME shows high consistency with pathological histology.NBI-ME can immediately make enterization classifica-tion and make monitoring recommendations.Whether it can completely replace biopsy needs further research.
