Endoscopic application of Gianturco-Rösch biliary Z-stent.

Ginaturco-Rösch Z-stent is a new self-expanding stainless steel stent for drainage of the obstructed biliary system. It has been used only with a percutaneous transhepatic technique. We describe a new method for endoscopic retrograde placement of a Gianturco-Rösch biliary Z-stent. This report describes our experience for endoscopic application of a Gianturco-Rösch biliary Z-stent in a patient with a benign stricture and multiple common bile duct stones.
