obstruction who were treated with a covered SEMS (21 patients) or a plastic stent (10 Fr, 23 …

Abstract Background and Study Aims: Metal biliary stents have been shown to be superior to
plastic stents with regard to patency and the risk of dislocation. However, tumor ingrowth …

Background Self-expandable metal stents (SEMS) are used for palliation of distal malignant
biliary strictures, but the role of covered SEMS is less clear. We performed an up-to-date …
