Brief Summary

In ERCP guidewires are used for the insertion of endoprostheses and the cannulation of stenosis. This leads to two essential requirements for the wire systems: The use of a (highly) flexible, hydrophilic wire to achieve successful and rapid passage of the narrow passage; for additional intervention, modern wires are equipped with a stable shaft with which e.g. bougies, dilatation catheters, or stents can be introduced. Guidewires are available with angled or straight tips whose use differ regionally. Guidewires with angled tips are used predominantly in Japan, whereas in the Western world incl. Germany straight wires are commonly used. In a recently published study examining the intubation of the native papilla, successful intubation of the papilla was faster with guidewires with angled tips than with guidewires with straight tips. However, this did not result in an effect upon the time-independent rate of the successful papilla intubation.

The investigators test the hypothesis that 1) a higher success rate of the ERCP can be achieved with the use of an angled guidewire than with a straight guidewire and 2) a higher success rate of the ERCP can be achieved with the use of a type 1 guidewire than with a type 2 guidewire
