 The aim of this study is to assess the feasibility and the safety of the Novel Motorized Spiral Endoscope to examine the colon. The study is conceived as proof of concept trial with the primary aim to achieve a cecal intubation rate of at least 90 according to quality guidelines recommendations. All other clinically relevant quality parameters of standard colonoscopy will be evaluated as secondary aims comparable to our recent trial. This study represents the first clinical evaluation of using a motorized spiral assisted endoscope for examination of the colon with potential advantages for patients in terms of effectiveness and convenience of colonoscopy.
