Esophagofiberscopic examinations (Olympus' E.F.S.) have been carried out in 510 cases in our clinic for past two and half years. During the interval a remarkable improvement of the instrument has been noted. Some important points are explained briefly as follows.
The air-flush, water-flush for cleaning the lens and the inspisated secretion of the esophagus can be done by pushing each button. Thus these actions are possible in one-hund (left hund).
The top of the instrument can be bent to 90° up and down directions. The end of the esophagus, the anastomotic portion between the esophagus and the stomach or the jejunum, and areas of anastomosis after gastrectomy are more easily observable.
When photographing, the camera can be attached to the eye-lens of the instrument more easily; and in using the T.T.L. system, the pictures are taken in the same condition.
