Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Hilar biliary obstruction usually involves the bifurcation of the biliary tract. Some researchers recommended unilateral stenting for malignant hilar biliary obstruction because drainage of 25% of entire liver can achieve the clinical success of biliary drainage. However, some researchers recommended bilateral stenting for malignant hilar biliary obstruction because some researches demonstrated that bilateral stenting can achieve a longer stent patency.In addition, there was no significant difference in post stenting survival between patients who were treated by unilateral or bilateral stenting. Therefore, it remains under debate whether unilateral or bilateral stenting is better in the treatment of malignant hilar biliary obstruction.
The purpose of this study is to compare the clinical effectiveness and long-term outcomes between patients with malignant hilar biliary obstruction who are treated by unilateral or bilateral stenting.
