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

摘要

PurposeClinical application of narrow band imaging facilitates diagnosis of esophageal neoplasia. However, no previous investigation has been conducted on magnifying endoscopy combined with narrow band imaging in detection 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.
