Abstract
The forward-viewing upper gastrointestinal fiberscope (Olympus GIF-Q10) developed on the basis of a new Olympus Endoscopy System was applied to 1, 380 cases of upper gastrointestinal endoscopy and its facility in manipulation, observation and others were evaluated. Owing to the improvement of image guide, increased ocular magnifying power, an extra wide visual field and stronger upward f lection of the tip (210°), manipulation, observation and recording ability were improved and there were no blind areas for observation. And it is easy to observe in detail because of increased ocular magnifying power. Moreover, a forcep's channel is set at the lower end of the manipulation part of this scope for protection of facial contamination by gush of dirt. It can be operated by a left hand only because of a shutter lever incorporated in the camera (SC-16) for a progress in manipulation. Otherwise, from the aspect of protection against infection of hepatitis virus and others, this scope is improved to be waterproof and can be immersed all of the scope in water, including the manipulation part to the universal cord parts, and this scope, therefore, tolerates enough against some chemicals (such as Hibitane gluconate, Sterihide). After all, this scope is evaluated clinically to be a more excellent upper gastrointestinal endoscope than former fiberscopes.
