The novel basket catheter for retrieval of a migrated biliary inside stent

Abstract

Many techniques have been reported for endoscopic retrieval of migrated biliary stents [1][2][3][4]. However, available devices such as forceps and snares are not suitable to grasp the migrated nylon thread attached to the biliary inside stent. The novel basket catheter (RASEN;

Rescue technique for basket impaction with a plastic stent, a rare complication of biliary inside stenting

“…The nylon thread attached to the IS was not found on the endoscopic image. Therefore, we inserted a rotatable 8‐wire basket (RASEN; Kaneka Medical, Osaka, Japan) to retrieve the migrated IS 1 . The IS's distal flange was easily caught by the basket, and we intended to remove it.…”

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

“…Recently, a dedicated inside plastic stent with removal of threads emerged for malignant hilar obstruction, with a longer patency period and easier removal 2 3 . However, the multiple inside plastic stent method harbors the risk of preceding stent migration owing to shear stress caused by the succeeding stents 4 . This article describes tips for preventing preceding stent migration using micro-alligator forceps through the two-devices-in-one-channel method 5 .…”

“…2 b, ▶ Video 1). The multiple inside plastic stent method for malignant hilar obstruction harbors issues caused by succeeding plastic stents, not only owing to the inward migration of the first stent [4] but also the difficulty in adjusting the first stent positioning. The two-devices-in-onechannel method [5] with microforceps can solve this problem.…”
