The aim of this study is to evaluate the usefulness of a newly developed multibending ultra-slim upper endoscope for the successful direct peroral cholangioscopy (POC) without assisting accessory in comparison with conventional ultra-slim endoscope. The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.
