Official Title: Prospective Multicenter Evaluation of a New Short-access-cholangioscope for Biliary Duct Strictures and Gall Stones
Brief Summary: Karl Storz GmbH (Gesellschaft mit beschränkter Haftung) company developed a cholangioscopic device, which is designed to give a better flexibility to the cholangioscopy tip in order to enable optimal diagnostic and therapeutic precondition. Other than the conventional mother-baby technique, the insertion of the cholangioscope (baby part) is done by a port at the side of a specially developed duodenoscope (mother part) which is prepositioned distally to the control unit, near to the patient's mouth. Better manoeuverability of the device tip will lead to both a better accuracy in taking biopsies as well as a better flexibility in lithotripsy manoeuvres. This study is designed to test the efficiency of the device in relation to this assumption.
