Colonoscopy Procedure

The goal of this clinical trial is to learn if patient administered propofol sedation results in superior patient satisfaction compared to nurse administered propofol sedation in diagnostic colonoscopies. • Does self administration of the sedative propofol increase patient satisfaction? Researchers will compare patient administered propofol sedation (where the patient administers propofol by pushing a button) with nurse administered propofol sedation (where a nurse gives the patient bolus doses of propofol as deemed necessary) Participants will: * Be randomized to either sedation route. * Answer a preendoscopy questioneere and a postendoscopy questioneere 1 hour after the examination as well as one week after the examination.

This pilot study will evaluate the usability and safety of software GI Genius™ XR in the Apple Vision Pro™ virtual reality headset when used in conjunction with the GI Genius™ system during routine screening and surveillance colonoscopy procedures. GI Genius™ XR enables colonoscopists to view the standard live endoscopic video feed within a virtual reality environment as an alternative to the conventional endoscopy tower display. The system provides a virtual screen that mirrors the tower video output without any image analysis or interpretation, allowing users to adjust screen size and position for optimal visualization and situational awareness.
