Unsedated colonoscopy utilizing virtual reality distraction: a pilot-controlled study.

Background: Sedation increases colonoscopy risks and prolongs recovery time. We examined whether virtual reality (VR) can substitute for sedation. The primary outcome was the overall satisfaction of patients who underwent colonoscopy with VR headset compared with patients who underwent standard sedation. Pain during the procedure, polyp detection rate (PDR), colonoscopy duration, post-colonoscopy adverse events, post-colonoscopy recovery, time-to-return to daily functions, and turnaround time at the endoscopy unit were secondary outcomes. Methods: The study was approved by Sheba Medical Center's ethics committee IRB number 21-8177-SMC. Sixty patients were sequentially enrolled in a 1:1 ratio to either standard sedated colonoscopy or VR-unsedated procedure, and all patients signed a written informed consent. 28/30 patients successfully completed the colonoscopy using VR headset. Overall satisfaction score was comparable between the groups. Results: There was no difference between VR and controls in colonoscopy duration, or PDR. VR patients had numerically lower rate of post-colonoscopy adverse events than controls. The proportion of VR patients who reported resuming daily activities on the day of the procedure was significantly higher than in the control group. The VR group patients spent significantly less time in the hospital compared to the control group. Conclusions: VR technology can provide adequate substitution for sedation for most patients undergoing colonoscopy and offers comparable patient satisfaction and faster return to daily activities.
