Abstract
FGI-FO, the experimental model of forward oblique viewing panendoscope, made by Machida-Seisakusho, Japan, was used in routine endoscopy on 80 patients / 83 times of examination and in emergency endoscopy on 8 patients / 8 times of examination. FGI-FO has a spherical distal end. A lens for observation, light suppling system, a small hole for air or water supply are arranged on the forward face. Thirty cm of distal end is more flexible than that of GIF-K (Olympus). For these distinctive feature, observation, with FGI-FO, of cardia (with reversal viewing), angulus and 2nd portion of duodenum was done more easily than with GFI-K. In emergency endoscopy, using FGI-FO, lens-cleaning and sucking of gastric juice and blood were done well and in routine endoscopy of postgastrectomy patients, obser-vation of remnant stomach and insertion to afferent and efferent limb were done easily. So we made a conclusion that FGI-FO is one of the useful panendoscopes for routine examination and emergen-cy endoscopy.
