The purpose of this study was to compare the difference in the stent patency duration between side-by-side fully covered self-expanding metal stents (SEMS) and side-by-side plastic stents in patients with malignant hilar biliary obstruction.
In the case of distal common bile duct obstruction, the SEMS was reported to be clinically superior to the plastic stent in previous studies. However, there are few studies comparing the two methods in patients with malignant hilar biliary obstruction. In contrast to the distal common bile duct obstruction, the advantage of plastic stents over SEMSs exists, and plastic stents are used commonly in real clinical practice.
