Didactic Potential of Videoendoscopy
Electronic videoendoscopy has only recently been introduced into clinical practice. The first endoscopes became available in Europe at the end of 1984, and in our Digestive Endoscopy Unit we were the first in Italy to employ this new equipment for outpatient endoscopy in May 1985. Since then we have performed examinations with all types of electronic systems. We have compared the traditional endoscopic television systems and have found the results with these poorer than those obtained with videoendoscopy; using a television camera reduces brightness and color by 25%. Furthermore, the electronic image can be modified, magnified, and manipulated, none of which is possible with traditional systems. Videoendoscopy is therefore an excellent means for endoscopic training.
