Abstract
Background and Purpose of Study: Endoscopic and percutaneous transhepatic stent placements are widely accepted as an effective treatment for palliating malignant biliary obstruction in surgically unfit or unresectable patients. However, it remains unclear which stricture- or stent-related factors influence stent patency. The goal of this study is to evaluate the metal stent patency according to various stent- and stricture-realated parameters and to identify the clinical factors influencing the stent patency before and after the procedure.
