Objective:To compare the diagnostic accuracy of white light endoscopy (WLE) and magnifying endoscopy combined with narrow-band imaging(ME-NBI) for intestinal-type gastric adenoma in benign lesions. Methods:Data of patients with suspected early gastric neoplastic lesions diagnosed with WLE were collected from the Shanghai Ren Ji Hospital from January 2016 to December 2017. Patients with suspected early gastric neoplastic lesions by WLE were examined with WLE,ME-NBI and targeted biopsy again within 2 weeks. The results of WLI,ME-NBI and biopsy were recorded. Using pathological diagnosis as the golden standard, diagnostic efficacy of WLE and ME-NBI for intestinal-type gastric adenoma and other non-adenoma lesions was evaluated.Results:A total of 232 patients (232lesions) were included, i.e. , 124 intestinal-type gastric adenoma and 108 other non-adenoma lesions such as atrophy, ulcers, hyperplasia, low-grade intraepithelial neoplasia, etc.). The sensitivity, negative predictive value and accuracy of ME-NBI in intestinal-type gastric adenoma were higher than those of WLE(92.7%VS71.8%, 91.6%VS73.7%，91.8%VS80.6%，all p<0.01), The specificity was consistent（both 90.7%），There was no significant difference in the positive predictive value between WLE and ME-NBI(92.0%VS89.9%, p>0.05). Conclusions:Diagnostic accuracy of ME-NBI in intestinal-type gastric adenoma from other non-adenoma lesions was significantly higher than that of WLE.
