Abstract
Background and objectives: recently, Olympus developed a new prototype (XCF-Q180AY2L) with responsive insertion tech- nology (RIT), which besides the still known variable stiffness tech- nology, included a passive bending section and a new high force insertion tube. Our objective was to investigate whether the use of this prototype could ease colonoscope insertion, increasing the cecal intubation rate, and/or shortening the cecal intubation time.

Material and methods: the study was designed as a prospective observational study in 305 consecutive patients from a colorectal cancer screening program. We compared colonoscopies performed with conventional colonoscopes (CFH180AL/CFQ160L) with those performed with the prototype XCF-Q180AY2L. End points were mean cecal and terminal ileal intubation times, cecum intubation rate, and need for specific maneuvers. All colonoscopies were per- formed under sedation with intravenous propofol. Finally, 288 patients were included.

Results: no complications were observed. Complete cecal intu- bation rate was 100 % in both groups. The ileum could be reached in 98.95 % of cases. Mean time required to reach the cecum was shorter in the prototype endoscope group (4.31 min, SD 2.63 min) than in the conventional endoscope group (4.66 min, SD 2.52 min) (p < 0.05). Compared with the standard colonoscope group, we observed in the prototype group less subjective sensation of difficulty in the passage of the sigma (p < 0.01), fewer maneuvers when it proved necessary to straighten the scope (p < 0.01), and less frequent need to modify the stiffness of the endoscope (p < 0.05).

Conclusion: we concluded that the prototype endoscope (XCF- Q180AY2L) facilitated colonoscope insertion, requiring slightly less time to reach the cecum than a standard colonoscope.
