Feasibility and Accuracy of Confocal Endomicroscopy in Comparison With Narrow-Band Imaging and Chromoendoscopy for the Differentiation of Colorectal Lesions

Abstract

Video acquisition with pCLE could not be achieved in a small number of lesions. The majority of pCLE videos demonstrated insufficient quality in more than half of the time recorded. Moreover, post-hoc accuracy of pCLE was significantly lower in comparison with real-time accuracy of CE and NBI. Future research should assess whether further increase in experience could improve pCLE video acquisition and determine the real-time accuracy of pCLE for differentiating colorectal lesions.
