N2 - Recent reports suggest that magnifying endoscopy with narrow band imaging (ME-NBI) is useful for the differential diagnosis of superficial gastric lesions. However, interpretation of the image is sometimes difficult even for experts, so it is unknown whether ME-NBI is useful also to endoscopists without expertise in ME-NBI. The aim of this study was to investigate the usefulness of ME-NBI for the novices to distinguish benign from malignant lesions of the stomach. Twenty-four participants, none of whom had expertise in ME-NBI, diagnosed the white light endoscopy (WLE) images of 50 superficial gastric lesions (17 cancers, 33 benign lesions). After presentation of 10 ME-NBI examples (5 cancers, 5 benign lesions), the participants again diagnosed the same 50 lesions with WLE as well as corresponding ME-NBI images. Adding ME-NBI to conventional WLE images significantly improved the diagnostic accuracy of superficial gastric lesions, from 62.8% with WLE to 72.8% with WLE plus ME-NBI (P<0.001). In conclusion, ME-NBI is useful to distinguish superficial lesions of the stomach even for observers without ME-NBI expertise.
