We read the commentary from Deng et al1 pertaining to our study of narrow-band imaging (NBI) for nonerosive reflux disease (NERD).2 We thank the authors for their interest in our study findings and the use of NBI for the workup of NERD. In our study, we recognized and noted subtle and distinct features in the distal esophagus using NBI in the near-focus magnification mode.2 As the authors acknowledge, several of these features (such as intrapapillary capillary loops) can be ascertained by the use of dual mode (normal and near focus) of currently available high-definition gastroscopes with second-generation NBI technology (ie, Olympus GIF-HQ-190) that were used in this study.
