 Three lesions(case 1, reddish 0−IIa lesion ; case 2, whitish esophageal intraepithelial neoplasia ; and case 3, inflammatory changes)detected using an endoscopic AI diagnostic support system(computer-aided detection[CADe])are presented. The sensitivity and specificity of CADe's blue laser imaging(BLI)and linked color imaging are 96−97% and 92−93%, respectively ; CADe is anticipated to improve the detection sensitivity of endoscopists who have little experience in narrow-band diagnosis. Conversely, in the esophageal region, where reddish 0−IIc lesions frequently occur, AI focuses on detecting changes that appear as brownish areas on BLI, and inflammation and epithelial atrophy, which are recognized as similar color changes, should be differentiated on the basis of magnification findings and biopsy results. Furthermore, of note, diagnosing the extent of the lesions is challenging, lesions with little color changes may be unrecognizable, and observation without blind spots is crucial because diagnosis solely relies on the displayed images.
