Objectives
Narrative objectives1
Many have reported the utility of endoscopic treatment using self-expanded metallic stent (SEMS) for lower or middle biliary stricture caused by malignancies.
There are two types in SEMS, Braded and Laser-cut type, and they have each different feature. In the present study, we will prospectively compare and estimate the clinical outcomes between the two types of SEMS.
