Reduced loop formation using a computer-assisted colonoscope (The NeoGuide System) compared with standard colonoscopy

Aims: Colonoscopy is an uncomfortable procedure for most patients. Discomfort during colonoscopy is largely related to looping of the colonoscope, which displaces the colon from its natural configuration and stretches attachments to the mesentery. The NeoGuide system utilizes a fully articulated, computer-controlled insertion tube that allows proximal segments of the colonoscope to follow the path taken by the tip as it is manually advanced though the colon. We hypothesized that this novel design would decrease the amount of colonic displacement due to loop formation. Methods: Ten gastroenterologists of varying…
