Endoscopists with lowest sedation rates detect more colorectal adenomas in colonoscopy than those most frequently using sedation

Background: The use of sedation in colonoscopy varies strongly and has been discussed with much controversy over the past few years. Endoscopists using sedation less frequently might do so in order to derive a benefit from a cooperating patient when performing position changes during colonoscopy, consequently improving adenoma detection rate (ADR). Methods: This study compared screening colonoscopy outcomes, in particular ADR, among 222 endoscopists with regard to respective examiners sedation rates (SR). An overall of 156,431 colonoscopies performed between 2007 and 2014 were linked to endoscopists who were the…
