Abstract

We described the usefulness of peroral videocholangioscopy for diagnosis of early bile duct cancer. In addition, we introduce the observation of the lesion using narrow band imaging in combination with a conventional white light imaging.

Supplementary material

Video clip 1. White light imaging by peroral videocholangioscpy detected slightly reddish papillary lesions in the middle bile duct. Narrow band imaging showed fine surface mucosal structure and mucosal capillary microvessel of the papillary lesion compared to white light imaging. Supplementary material 1 (MPEG 10,635 kb)
