Covered vs Uncovered Metal Stents for Palliative Biliary Decompression in Inoperable Malignant Distal Bile Duct Obstruction

March 4, 2022 updated by: Patrick Yachimski, Vanderbilt University Medical Center

Randomized Controlled Trial Comparing Covered Versus Uncovered Metal Stents for Biliary Decompression in Inoperable Malignant Distal Bile Duct Obstruction

The purpose of this study is to compare the rate of long-term stent failure, defined as need for repeat biliary intervention following placement of C-SEMS vs U-SEMS for palliation of inoperable malignant distal bile duct obstruction.
