前方斜視型ファイバースコープFGI-FOの使用経験

抄録

Recetly, urgent endoscopic examination has been undergoing for upper gastrointestinal hemorrhage. And, various types of panendoscope which can observe from the esophagus to the bulbular portion are made. Forward oblipue viewing endoscopy (FGI-FO) is newly developed by MACHIDA Co. also for this purpose. The most characteristic point of FGI-FO is angles of view directed obliquely 30 degrees from the longitudinal axis of the instrument. We have used this fiberscope on 102 cases and following results are obtained. The esophagus was satisfactorily observed as well as forward viewing instruments. The stomach was entirely observed, and in about half cases the gastric angle was easily observed in front. The duodenal bulb was easily orientated for observations.
