✦ Synopsis

Study design/materials and methods:

The aim of this experimental study was to investigate the effect of nd:yag laser on metallic tracheobronchial stents, because nd:yag laser could be used for resection of tumourous tissue growing through stent meshes (strecker-, palmaz-, wallstent).

Study design/materials and methods:

An in vitro worst-case-model was used to investigate the effects of different types of laser application on metallic stents: non-contact application, and contact application with bare fibres and with hemispherical sapphires.

Results:

In the non-contact method and with bare fibres stent destruction occurred at power settings exceeding 10 w, whereas in the contact method with hemispherical sapphires power settings of 20 w were possible without stent damage.
