There was no significant difference of positive cultures when comparing the duodenoscopes undergoing DHLD (8 positive cultures, 1.8%) with duodenoscopes undergoing LCS (9 positive cultures, 2.1%; P= .8). Both groups had 2 cultures that grew high-concern organisms (.5% vs .5%, P=1.0). No multidrug-resistant organisms, including carbapenem-resistant enterobacteriaceae, were detected. DHLD and LCS both resulted in a low rate of positive cultures, for all organisms and for high-concern organisms. However, neither process completely eliminated positive cultures from duodenoscopes reprocessed with 2 different supplemental reprocessing strategies.

Artificial intelligence (AI)-assisted polyp detection systems for colonoscopic use are currently attracting attention because they may reduce the possibility of missed adenomas. However, few systems have the necessary regulatory approval for use in clinical practice. We aimed to develop an AI-assisted polyp detection system and to validate its performance using a large colonoscopy video database designed to be publicly accessible. To develop the deep learning-based AI system, 56,668 independent colonoscopy images were obtained from 5 centers for use as training images. To validate the trained AI system, consecutive colonoscopy videos taken at a university hospital between October 2018 and January 2019 were searched to construct a database containing polyps with unbiased variance. All images were annotated by endoscopists according to the presence or absence of polyps and the polyps' locations with bounding boxes. A total of 1405 videos acquired during the study period we
