Linked color imaging and blue laser imaging for the diagnosis of superficial non-ampullary duodenal epithelial tumors

This study aimed to evaluate endoscopic findings using linked color imaging (LCI) and blue laser imaging (BLI) and to determine a diagnostic predictor for duodenal adenocarcinomas. Methods: All consecutive patients who underwent endoscopic resection for superficial non-ampullary duodenal epithelial tumors (SNADETs) between October 2012 and June 2019 were enrolled in this study. Two highly experienced endoscopists investigated six morphological findings using both white light imaging (WLI) and LCI and three magnifying endoscopic findings using magnifying BLI (M-BLI). Results: A total of 90 patients with 110 SNADETs, including 87 adenocarcinomas and 23 adenomas, were analyzed in this study. Among the non-magnifying endoscopic findings, the presence of reddish color sign, orange color on LCI (orange color sign), lobulation, depression, and marginally white opaque substance (WOS) were found significantly more frequently in adenocarcinomas than in adenomas (P=0.015, P
