[Endoscopy by color television--a new technique? (author's transl)].
The routine endoscopic examination by color television is possible be new technical developments. For routine color television - endoscopy an efficient three-tube-camera should be used, directly attached to the endoscope. For demonstration purposes or to control technical proceedings in the field of operative endoscopy the one-tube-color television camera can be sufficient, even if there are difficulties also for the experienced examiner to read findings from the television screen. This difficulty do not exist with the three-tube-camera. The resolution power of the endoscope in comparison to the television picture of the endoscopic color television picture is not different. The resolution power is limited by the endoscopes. An enlargement of the endoscopic picture by changing the focus of the objective gives no improvement. We have excellent experiences with the routine color television-endoscopy during colonoscopy. With a three-tube-camera the total examination can be controlled while the one-tube-camera is only valid to insert the coloscope. The color television endoscopy enables to produce a large archive of endoscopic findings for teaching purposes without secondary cost and with a description during the active examination. Our experiences with routine endoscopy with color television proves that this technique is an improvement.
