Objective To evaluate the differential diagnostic value of endoscopic narrow band imaging(NBI)in early gastric cancer(EGC)and precancerous lesions.Method A total of 80 patients with suspected EGC and precancerous le-sions were selected.All patients underwent routine endoscopy and endoscopic NBI examinations.The image clarity of routine endoscopy and endoscopic NBI was compared.The pathological diagnosis results were used as the gold standard,the results of routine endoscopy and endoscopic NBI were compared with pathological diagnosis results,and to analyze their differential diagnostic value in EGC and precancerous lesions.Result The image clarity scores of endoscopic NBI were significantly higher than those of routine endoscopy,and the differences were statistically significant(P＜0.01).The accuracy,specificity and sensitivity of endoscopic NBI in the diagnosis of EGC and precancerous lesions were higher than those of routine endoscopy.The consistency between conventional endoscopy and pathological diagnosis was poor,while the consistency between endoscopic NBI and pathological diagnosis was good.Conclusion Endoscopic NBI has high differential diagnostic value in EGC and precancerous lesions,and can provide reliable basis for diagnosis and treat-ment of diseases,so as to improve the prognosis of patients.
