The Efficacy of Plastic Stent Anchoring to Reduce Migration of Metal Stent

연구 개요

The aim of this study is to demonstrate that the group with an additional plastic stent to anchor the fully covered self expandable metal stent (FCSEMS) in patients with malignant biliary stricture has less stent migration than the group with FCSEMS only. The primary outcome is stent migration for 6 months. The secondary outcomes are stent related adverse events, stent patency, and overall survival.
