- Abstract: Objective To analyze the application effect of narrow band imaging(NBI)combined with magnifying endoscopy(ME)in early gastric cancer(EGC)screening.Methods A total of 199 patients who found focal lesions by ordinary white light endoscopy(WLE)were selected from April 2022 to October 2023.NBI combined with ME examination was performed,and histopathological examination of the specimen obtained from the lesion area was conducted.The pathological diagnosis results were recorded,and the endoscopic image qualities of WLE and NBI combined with ME examination were observed.The consistency between WLE,NBI combined with ME and patho-logical diagnosis was analyzed.The diagnostic value of WLE and NBI combined with ME for EGC was evaluated.Results The image qualities of microvascular and glandular duct by NBI combined with ME were better than those by WLE(P<0.05).The consistency between WLE diagnosis and pathological diagnosis was comparatively strong(Kappa=0.687).The consistency between NBI combined with ME and pathological diagnosis was very strong(Kappa=0.947).The consistency between NBI combined with ME and pathological diagnosis was better than that of WLE.The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,and area under the curve(AUC)of NBI combined with ME in diagnosing EGC were higher than those of WLE,with statistically significant differences(P<0.05).The AUC of NBI combined with ME for diagnosing EGC was higher than that of WLE,with statistically significant difference(Z=3.493,P=0.000).Conclusion NBI combined with ME can increase the diagnostic efficiency of EGC,along with good image quality.
