Various core/cladding plastic lightguides have been investigated with
respect to their optical properties and suitability for endoscopic
photo-coagulation. Plastic fibres with a diameter of 1.5 mm and a
polystyrene or polymethyl-methacrylate core proved to be best suited to
meet the requirements of high optical-power performance, low optical
attenuation, mechanical robustness, sufficient flexibility and
capability of being integrated in existing endoscopes. No impairment of
endoscopic manipulation could be observed in more than 200 endoscopic
photo-coagulations performed in the canine gastrointestinal tract. The
plastic fibre can easily be introduced into and withdrawn from the
instrumental channel without restricting the flexibility of the
endoscope. The easy sliding of the fibre within the instrumental channel
permits a dynamic variation of the distance between fibre and tissue
during a photocoagulation, thereby varying the spot size and power
density of irradiation continuously. The optical and mechanical
performance of the plastic fibre is far beyond the current requirements
of laser endoscopy. The plastic fibre is thus a most promising and
easy-to-handle optical transmission system for endoscopic
