The forward viewing f iberscope GIF type D has been widely used as an indispensable tool for the examination of the upper G. I. tract, since it was developed in 1971 by Olympus Optical Co. Recently the fore-oblique viewing f iberscope GIF type K has been introduced, representing further modifications of the GIF type D. Compared with the GIF-D, two main improvements are seen in the GIF-K: 1) The objective lens is placed 30° obliquely against the longitudinal direction of the (iberscope, 2) The distal end of this new f iberscope is metaltipped. We have used the new fiberscope on 93 cases between June and December 1974, whose classifica-tion is: 2 cases of esophagitis, 4 cases of esophageal cancer, 2 cases of esophageal varices, 22 cases of gastritis, 22 cases of gastric ulcer, 7 cases of gastric cancer, 2 cases of gastric submucosal tumor, 8 cases of gastric polyp, 5 cases of operated stomach, 11 cases of duodenal ulcer and 11 normal cases. From observations of the above cases examined with GIF-K, the following two points should be considered as advantages of this new type of the instrument: 1) It makes easier for us to pass the tip of the f iberscope through the esophageal entrance. 2) We can easily observe the side of the lesser carvature at the gastric angle and the pyroric antrum which are regarded as relatively blind spots using forward-viewing type endoscopes.
