 The future prospects for the development of gastrointestinal diagnosis by employing electronic endoscopy are outlined. Screening examinations are characterized by a trend to focus on the least invasive approach to minimize the pain that patients have to endure. This is heading in the direction of developing wireless capsule endoscopes with the insertion portions reduced in size while maintaining their observation and processing capacities and ultimately even with their inserted sections detached from the operating parts. Electronic endoscopes about 5 mm in external diameter have already been produced. We may expect that oral or transnasal endoscopic diagnoses will be safe and provoke minimum pain, the smaller they are in size. We may also expect diagnostic capacity to improve because resolution during examination will be upgraded and image-analyzing capability will increase by the utilization of endoscopic systems that produce high-resolution imaging, together with the development of diagnostic endoscopes represented by such sophisticated instruments as endoscopic ultrasonography, fluorescent endoscopy, and ultra-high magnifying endoscopy. The age of “Bioendoscopy” will be realized when the pathophysiological state of diseases can be clarified by combining the morphological diagnosis of conventional endoscopy, with diagnosis at the cytological level by utilizing ultra-high magnifying endoscopy and functional diagnosis by fluorescent or infrared fluorescence endoscopies. To illustrate the improved processing and operating capabilities, the current status of the development of multi-bending scopes, colonoscopes with adjustable hardness, endoscope position detecting units, and self-propelled endoscopes was described.
