ORIGINAL RESEARCH Magnified Endoscopy Combined with Narrow Band Imaging of Minimal Superficial Esophageal Neoplasia—Indicators to Differentiate Intraepithelial Neoplasias

# The Author(s) 2012. This article is published with open access at Springerlink.com Purpose Clinical application of narrow band imaging facil-itates diagnosis of esophageal neoplasia. However, no pre-vious investigation has been conducted on magnifying endoscopy combined with narrow band imaging in detec-tion of minimal superficial esophageal neoplasia, which is defined as neoplasia <10 mm in diameter. The aim of this retrospective study was to evaluate the usefulness of this combined technique in the differential diagnosis of minimal superficial esophageal neoplasia
