The future of endoscopy.

Extraordinary developments have occurred in the field of endoscopy over the past 40 years. The era that began with the fiberoptic endoscope (fiberscope) has now moved to the videoscope and, more recently, to the capsule endoscope. Videoendoscopy will remain the major form of endoscopy for the next 5-10 years but, thereafter, diagnostic procedures including colonoscopy will increasingly be performed by capsule endoscopy. This change will be largely driven by patient preference rather than superior results from capsule studies. Image analysis of capsule studies will be accelerated by software that highlights abnormal areas and, by 2025, capsule studies will be 'read' by computer. For the next decade, more complex therapeutic procedures will be performed by a new group of therapeutic endoscopists using advanced videoscopes. Several new therapeutic procedures will emerge but natural orifice transluminal approaches will need to compete with advances in laparoscopic techniques. It is also likely that health administrators faced with escalating medical costs will demand that new and more expensive procedures not only facilitate patient care but result in superior health outcomes.
