As its image sensor, the electronic endoscope incorporates the so‐called charge‐coupled device (CCD) at its tip. The device was developed by the high technology of microelectronics, and it has a quite new construction, different from fibre‐optics. Two years after the electronic endoscope was produced first by Welch‐Allyn from the USA, the first Japanese electronic endoscope model was developed in 1985, and now an upper gastrointestinal model, a duodenoscope model, and a colonoscope model are available commercially from four companies worldwide.
