Suprapapillary trisectoral deployment of slim fully covered metal stents with ultra-stiff high-sliding guidewires for malignant hilar biliary obstruction

Fig. 2 Fluoroscopic images.a Three novel, ultra-stiff, high-sliding guidewires were placed into the right posterior, right anterior, and left hepatic ducts, respectively.b The delivery system of the first slim, fully covered metal stent was introduced over the left guidewire and deployed across the stricture and above the papilla.c The second metal stent was then inserted over the posterior guidewire.d The second stent was deployed alongside the left metal stent.e Finally, the third metal stent was inserted over the anterior guidewire.f The third stent was deployed in a stent-by-stent configuration.
