Guidewire passage through metal stent mesh using a novel sphincterotome during the stent-in-stent technique Video 1 Use of a novel sphincterotome to facilitate guidewire passage through the metal stent mesh during the stent-in-stent technique. Fig. 1 The novel sphincterotome (ENGETSU; Kaneka Corp., Osaka, Japan) has two cutting functions.a Normal configuration.b Pull config- uration.c Push configuration. Fig. 2 The novel sphincterotome also demonstrates superior rotational performance, enabling stepwise 180-degree rotation in both clockwise and counterclockwise directions.
