THE CLINICAL EVALUATION OF THE UPPER G-I ENDOSCOPY WITH SMALL CALIBER FIBERSCOPE FGI-X₁ (MACHIDA)

-Through the 2nd screening of gastric mass-servey-

Abstract

Recently, the various type of pan-endoscope are made for several purposes. About pan-endos-cope which can observe from the esophagus to the bulbous portion, small caliber type seems to be sufficient. particularly for the routine examination and the 2nd screening examination of gastric mass-servey.In 100 cases that was required the 2nd screening of upper G-I tract in mass-servey, the endoscopy using the small caliber fiberscope FGI-X₁ (Machida) was done easily and less pain-fully as well as using the small caliber f iberscope GIF-P₂ (Olympus). As a conclusion, this FGI-X₁ type pan-endoscope was very sufficient for the 2nd screening of gastric mass-servey. Specifications of this f iberscope are as follows: forward field view, out diameter 9.5mm, angle of view field 75°, working length 1.045mm, bending angle up to 180° down to 90°, right and left 120°.
