A new videoendoscope system (Welch-Allyn VideoEndoscope system) has been recent-ly developed. The image detected by the CCD chip which attached to the distal tip of the endoscope is passed in the form of an electronic signal through the endoscope to the video processor for display by the television monitor. Since the image of the videoendoscope is produced electronically, computer enhancement of the image and/or computer analysis on the mucosal changes of the GI tract become gotten in our pocket. We tried endoscopic examinations of the upper GI tract with Videogastroscope in 37 patients, and by the computer enhancement and computer analysis of the image minute morphological changes on the surface of the gastric mucosa were clarified. There is still some problems with this system, however, this system is likely to be useful and effective for more detailed diagnosis of the gastric disorders.
