Results: A simple classification system for in vivo diagnosis of duodenal epithelial tumors by using CLE was developed and validated. The sensitivity, specificity, and accuracy were 90%, 100%, and 97%, respectively. Positive and negative predictive values were calculated as 100% and 96%. The kappa coefficient representing consistency was 1 between observers and within each observer.
