CLINICAL ASSESSMENT OF GF-10 AS A PANENDOSCOPE

Abstract

The GF-10 (Olympus)-side-viewing type endoscope- was used as a panendoscope for 108 cases and compared ability of observation for several parts of upper G.I. tract with that of GIF-P₂, P₃-forward-viewing type endoscope for 211 cases. All cases did not have remarkable deformity and organic lesion in upper G. I. tract. In middle esophagus, EC junction, greater curvature of gastric body, prepylorus of the stomach and duodenal bulb, where it seemed difficult to observe with side-viewing type endoscope, ability of observation with GF-10 was almost same as forward-viewing type endoscopes. On the contrary, GF-10 was superior to forward-viewing type endoscopes in duodenal 2nd portion. For 644 cases who did not have remarkable lesion in the esophagus, GF-10 was inserted easily to duodenal bulb in 95.3% cases, and to duodenal 2nd portion in 85.7% cases. Then we examined 393 cases with GF-10 and 419 cases with a thin forward-viewing type endoscope who were recommended to take close examination after mass screening of upper G. I. series. In gastric body, more gastric ulcer scar cases were found with GF-10 than with a thin forward-viewing type endoscope. No significant difference was found between these endoscopes in ability to detect ulceration and polyps in other portions, though more polyps were found with GF-10. These results suggest that GF-10 is available as a panendoscope, and may detect more cases of minute lesion than thin forward-viewing type endoscopes.
