 The diagnostic criteria for NBI magnification of SNADETs(superficial nonampullary duodenal epithelial tumors)have not yet been established. We previously proposed a new NBI classification for SNADETs and validated this classification in the present study. A total of 52 SNADETs treated using endoscopic resection were enrolled and divided into two groups(monotype and mixed type)based on NBI magnification. When the mixed-type group was considered as a diagnostic criterion for high-grade adenoma or adenocarcinoma, diagnostic accuracy, sensitivity, and specificity were 78.8%, 87.8%, and 45.5%, respectively. This result suggests that NBI magnification may be useful for endoscopic diagnosis of SNADETs.
