EXPERIENCE IN MASS SURVEY WITH A NEW FORWARD VIEWING PANENDOSCOPE TYPE FG-28A, ASAHI.

Abstract

At present, the succesf ullness of mass survey endoscopic examination depends on easiness of introduction, observation and recording capacity of the endoscope. We used a forward-viewing panendoscope, typeFG-28A (ASAHI Optical Co, Ltd) in 205 mass survey examination and 86 routine examination. This new fiberscope was proved to introduce, but as well as the other similar scope (GIF-P2) the enough observation of posterior wall of lower body was very difficult. Otherwise, observation of the whole upper G. I. tract was possible. The quality of the photograph was taken well. The difficulty of enough visualization of the lower body and aiming biopsy should be improved. Generally speaking, the scope was usef ullness for upper G. I. tract.
