90% of colonoscopies are performed with general anesthesia (GA). GA carries risks and requires a prior anesthesia consultation, a dedicated team and technical platform on the day of the examination. These constraints increase the time it takes to organize examinations. This was particularly highlighted during the recent health crisis. The success of colonoscopy without GA varies depending on the patient's experience of the examination. Any measure allowing better tolerance of the exam is therefore likely to increase its success rate and avoid rescheduling the exam under GA. A 2017 meta-analysis showed that the use of virtual reality (VR) reduced pain and anxiety during care for burn victims, in trauma and oncology. In upper digestive endoscopy, retrospective studies have shown good tolerability of the examinations and a reduction in pain compared to patients with only local anesthesia. Thus, if the VR mask improves the success rate of total colonoscopy by improving tolerance and acceptability, more examinations without GA could be considered. It could also have an economic impact.
