Description
83° and offers an adequate field of view with excellent optical resolution. The external suction channel requires additional tubing, making the instrument more cumbersome while adding to its weight. Since the instrument is new, it is too early to assess resistance of the bundles to irradiation. The instrument available for evaluation, however, had been used for approximately 150 examinations and the bundles were only slightly yellow. The Pentax lecturescope is very good, adapting both clockwise and counterclockwise to avoid interference to the endoscopist and losing little light. The Pentax endoscope can be easily adapted to any manufacturer's light source, again with little light loss. In general, the instrument handled very well and offers an excellent alternative to the other endoscopes.
