Colonoscopy, Intubation Time, Cap-assisted Colonoscopy
Conditions
Brief summary
This prospective, randomize, controlled trial will compared cap-assisted water exchange with water exchange in patients undergoing sedated colonoscopy. Investigators test the hypothesis that that cap-assisted water exchange is more efficient and causes a shorter insertion time.
Interventions
