 The development of magnifying endoscopy has advanced against the basic background of stereomicroscopy research. In 1967, a gastrointestinal endoscope was used to produce the first magnifying fiberscope for the purpose of magnified observation in vivo, and the development continued thereafter until 1977, with the stomach as the subject. The first magnifying colonic fiberscope was reported in 1975. In addition to the widespread adoption of electronic endoscopes in the1990s, magnified clinical observation of the colorectal mucosa began to attract attention as a result of the diagnosis and treatment of many micro-cancers and flat and depressed-type early cancers. Magnified observation of the stomach, on the other hand, has also become relatively easy as a result of various advances in recent years. Since 2000, there has been development and general use of magnifying endoscopes that have the same size and maneuverability as general-purpose endoscopes for the upper gastrointestinal tract and that have adequate resolution and observation depth at their maximum magnification. Dramatic advances have been made in magnified observation of the esophagus and pharyngeal region, especially as a result of combined use with narrow-band imaging(NBI).
