Covered versus uncovered self-conformable metal stent for palliation of primary malignant extrahepatic biliary strictures: a randomized multicenter study

Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstruction. We aimed to compare stent patency, adverse events rate and overall survival of covered (Niti-S Biliary ComVi) versus uncovered (Niti-s D type) self-conformable metal stents in patients with primary malignant extrahepatic biliary stricture, not eligible for surgery.
