Title: Sa1943 COECAL INTUBATION TIME WITH THE 3D NAVIGATION SYSTEM SCOPEPILOT VERSUS STANDARD COLONOSCOPY
Abstract: The successful intubation of the coecum is one of the main challenges in colonoscopy. Looping of the endoscope could hinder reaching the coecum or even makes it impossible. The 3D navigation system SCOPEPILOT by Pentax allows a real time position monitoring of the endoscope during colonoscopy useing MRI-technology and should facilitate the intubation of the coecum. The aim of this study was to compare the coecal intubation time with SCOPEPILOT versus standard endoscopy. From January 2017 200 patients with an indication for a colonoscopy were recruited for this study and randomized to either colonscopy with SCOPEPILOT or standard colonoscopy. Five endoscopists (two learner and three experienced endoscopists) performed the examinations. The time until intubation of the coecum was measured, the quality of the bowel preparation rated (range 1-6) and the subjective benefit for the endoscopist during the examination registerd. In case of looping of the endoscope the form of loop was documented. The average age in both groups was 61 years. The quality of bowel preparation was similiar as well (2.49 vs 2.76). The coecum was reached in all examinations. The time until sucessful intubation of the coecum was in the standard group 8.99 min (± 4.9) whereas with the SCOPEPILOT the coecum was reached in 6.33 min ( (± 3.86), which was significant faster (p < 0.005). Especially the two less experienced endoscopists reported an earlier recognition and easier characterization of looping. Thus especialy the number of examinations with a coecum intubation time greater than 10 min were significantly reduced. The sigma-N-loop was the most common loop followed by an alpha-loop. With the 3D navigation system SCOPEPILOT a significant faster intubation of the coecum is possible. An earlier recognition and characterization of looping which results in a more effective solving of the loop seems to be the reason. Especially for beginners and in technical difficult colonoscopys the SCOPEPILOT can be an useful tool and should be considered.
