Additional effect of magnifying narrow‐band imaging on estimating the invasion depth of superficial esophageal cancer

摘要

To investigate whether assessment by magnifying narrow‐band imaging (M‐NBI) based on the classification of the Japan Esophageal Society provides additional value to the estimation of the invasion depth of superficial esophageal squamous cell carcinoma (SCC) compared with assessment by white light endoscopy (WLE) alone.
