The study is based on a home made questionnaires completed by the operator and the patient before and after the colonoscopy.
Colonoscopy is an exam which can be responsible for pain and discomfort for the patient.~Therefore colonoscopy is performed most of the time under general anaesthesia. Moreover, drug-induced sedation comes with adverse effects especially among fragile patients.~Besides, monitoring patients during and after sedation is both logistically demanding and costly.~Virtual reality offers immersive and three dimensional experiences that distract the attention and might improve patients comfort.~The aim of the study is to investigate the use of virtual reality during colonoscopy versus general anaesthesia.
