Narrow Band Imaging with Magnification Can Pick Up Esophageal Squamous Cell Carcinoma More Efficiently Than Lugol Chromoendoscopy in Patients after Chemoradiotherapy

<table>Seventy-two lesions biopsied from the Lugol-positive lesions were analyzed. The lesion observed as a well-demarcated brownish area with abnormal changes of intraepithelial papillary capillary loop (IPCL) pattern by NBI with magnification was defined as NBI positive.
