THE OBSERVATION OF THE ESOPHAGUS AND THE GASTRIC CARDIA BY THE ESOPHAGOFIB-ERSCOPE WITH THE STRONGLY BENDING MECHANISM

Abstract

The newly modified esphagoscope with its top movable up to 2000, has been used for the observation of the esophagus and the gastric cardia. The length of the bending portion was 5.8cm. It was longer than that of the usual type of EF, but shorter than that of GIF-D. Manipulation of the instrument was same as the usual EF-B. II. There was no blind portion in the whole esophagus. The gastric cardia was seen from oral side for the first time, then inserting fiberscope into the stomach, observed from the stomach with 200° angle mechanism. The esophagogastric junctional area and the fornix was seen in the nearer distance and in the front of view. The examination was carried out in 88 cases of cardiac tumor, ulcer, achalasia and varices. The damage of the image glass fiber of the fiberscope was not increased in this mechanism.
