- W2377057721 abstract "Objective To evaluate the value of narrow-band imaging (NBI) in the diagnosis of early esophageal cancer and precancerous lesion. Methods Ninety patients were diagnosed as early esophageal can-cer or precancerous lesions (138 lesions). The esophagus was examined with ordinary endoscopy and NBI en-doscopy respectively, pit pattern and blood capillary form were examined with routine magnifying endoscopy and NBI endoscopy. Finally, 1.2% Lugoul's iodine solution was used to stain the esophageal mucosal surface, biopsy was taken at the sites which NBI or iodine staining positive, all lesions were confirmed by pathologic diagnosis as the gold standard, NBI and iodine staining scale was compared with pathologic diagnosis. Results One hundred and four (75.4%) lesions were detected with ordinary endoscopy, 120 (87.0%) lesions were de-tected with NBI endoscopy, 138 (100.0%) lesions were detected with iodine staining. The lesion detecting rate of NBI was lower than that of iodine staining (P 0.01), however, there was no significant difference between NBI and iodine staining for the diagnosis of high grade intraepithelial neoplasia(P 0.05), the main difference was that the detecting rate of NBI was lower than that of iodine staining for the diagnosis of low grade intraep-ithelial neoplasia (P 0.01). Conclusions Pit pattern and blood capillary form of early esophageal cancer and precancerous lesion could be clearly demonstrated with NBI than with ordinary endoscopy. The combination of NBI and iodine staining could raise the diagnostic rate of early esophageal cancer and precancerous lesion." @default.
