    Yun Nah Lee et al. Direct peroral cholangioscopy for diagnosis of bile duct lesions using an I-SCAN ultraslim endoscope: a pilot study

    This study evaluates the usefulness of direct peroral cholangioscopy using I-SCAN digital contrast compared with conventional white-light imaging (WLI) in 20 patients with bile duct lesions. Although the quality of endoscopic visualization with I-SCAN was significantly higher than that of WLI, the diagnostic accuracy of visual diagnosis was not different between the two modalities
