Details and patient eligibility

About

This prospective, randomize, controlled trial will compared maximal to half-maximal suction pressure applied during water exchange in patients undergoing minimally sedated colonoscopy. We test the hypothesis that maximal suction pressure is more efficient and causes shorter insertion time.
