The new scopes--broadening the colonoscopy marketplace.
Colonoscopy has been established as a screening tool for colorectal cancer and precursors in some countries. Efforts to improve instrument performance as well as patient comfort, safety and compliance have led to modifications of existing endoscopes as well as to the development of new scopes with different working mechanisms, including the colon capsule. While the former have not substantially changed performance, the true value of new scopes - partially single use and/or self propelling - can not be fully assessed, since they are either still under development and/or tested only in animals and in small groups of patients or volunteers. The colon capsule holds promise but has a too complicated preparatory regimen and too low a sensitivity at the moment. Future developments and further studies will show which of these techniques may complement or even replace traditional screening colonoscopy.
