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.

cholangioscopy with Frimberger duodenoscope system by the company of Karl Storz GmbH
Eligibility Criteria
You may qualify if:
- Choledocholithiasis, not treatable through conventional ERCP with sphincterotomy.
- Stricture of the biliary duct in need of histopathological investigation
You may not qualify if:
- Aggravated or impossible access to papilla
- Inappropriate biliary anatomy, e.g. multiple strictures or diameter of duct \< cholangioscope impairing intubation
- Primary sclerosing cholangitis
- Coagulopathy (quick \< 50%, thrombocytes \< 50/nl)and anticoagulant medication
- Bad patient's condition (ASA IV)
