Modified double-guidewire technique using a unique double-lumen sphincterotome for difficult biliary cannulation

摘要

The MagicTome (PIOLAX, Tokyo, Japan) is a novel sphincterotome. It is a double-lumen sphincterotome with independent ports for the pancreatic duct guidewire and bile duct guidewire, both measuring 0.025 inches in diameter. The proximal portion of cutting wire is insulated to avoid mucosal injury during sphincterotomy.
