Two-devices-in-one-channel method for preventing the preceding stent migration in case of multiple indwelling biliary inside plastic stents

Securing threads with a novel clip to prevent preceding stent migration in multiple biliary inside plastic stents

“…However, proximal dislocation of the first stent during second stent insertion can occur owing to interference between the stents. Although the two‐devices‐in‐one‐channel method with micro forceps may help prevent stent migration, 3 it may restrict scope maneuverability. Here we describe a novel technique for preventing the first stent migration in a patient with unresectable malignant hilar obstruction.…”
