Core Tip

Core Tip: This single-center, retrospective study investigated eighteen patients with unresectable malignant hilar biliary obstructions treated with a novel uncovered biliary metallic stent [Moving Cell Stent (MCS); BCM Co., Ltd., Gyeonggi-do, South Korea], specifically designed for hilar reconstruction, using stent-in-stent technique via percutaneous approach. Primary endpoints were clinical and technical success. The study results indicate that percutaneous MCS placement using stent-in-stent technique is feasible and safe. Comparison with other stents demonstrated superiority in both stent patency and technical success.
