SECONDARY outcome

Timeframe: During colonoscopy procedure

Comparison of the insertion time, overall withdrawal time, inspection time, and total procedure time between the AmplifEYE colonoscopy and the Endocuff Vision colonoscopy. Insertion time: time it takes from the colonoscope first being inserted to when the cecum is reached Withdrawal time: time calculated from when withdrawing is started in the cecum until the colonoscope is removed. This includes time spent washing, suctioning, inspecting the colon, and removing polyps. Inspection time: time spent actually examining the colon and does not include time spent for washing the colon, suctioning, and removing polyps. Total procedure time: time from the initial insertion of the colonoscope through the complete withdrawal of the colonoscope.
