  • Look Inside

 It goes without saying that the panendoscope is extremely essential for endoscopic examination of the upper gastrointestinal tract because one can observe them as serial organs through it. But there are some problems in the observational capacity of the forward-viewing type panendoscope from the viwpoint of close endoscopic examination in the stomach. First, it is difficult to seen en face lesions on the lesser curvature and posterior wall of the gastric body. Second, although the panendoscope is indeed advantageous in getting a wide view of an area by the aid of the wide-angle lens, when compared with the narrow viewing angle, it is less effective in the magnification of the lesions in the same distance between the lens and lesions. Thus, it does not enable detailed observations. Therefore, when one conducts panendoscopy, this disadvantage must be kept in mind so as not to overlook tiny lesions. Moreover, authors maintained that the side-viewing type fiberscope with relatively narrow viewing angle should be put into full use according to the regions that the lesions are located.
