| Popis: | Aim: Most screening examinations in Japanese general hospitals are carried out by high-definition television-incompatible (non-HD) scopes and non-magnifying endoscopes. We evaluated the narrow-band imaging (NBI) real-time diagnostic yield of esophageal neoplasia in high-risk patients at a general hospital. Methods: In a single-center, prospective, non-randomized controlled trial, 117 consecutive screening patients with high risk for esophageal cancer received primary white-light imaging (WLI) followed by NBI and iodine-staining endoscopy (59 by HDTV-compatible [HD] endoscopy and 58 by non-HD endoscopy). The primary aim was to evaluate the diagnostic yield of non-magnified images in diagnosing esophageal neoplasia. The secondary aim was to compare HD endoscopy and non-HD endoscopy in terms of diagnostic performance. Results: Overall, the sensitivity of NBI for screening of esophageal neoplasia was superior to WLI, and equivalent to iodine staining (92% vs 42%; P |
