However, whether it results in a favorable effect on colonoscopy outcomes and performance compared to standard sedation with benzodiazepines/opiates remains unclear.Objectives: To determine the effect of propofol-mediated sedation on colonoscopy-quality measures compared to traditional sedation.Methods: A large cohort of 44,794 patients who had undergone sedated colonoscopies were included. Colonoscopy-quality indicators were examined in benzodiazepine/opiate-sedated patients and compared with a propofol-mediated sedation group. Adjustment for potential confounders, such as age, sex, quality of bowel preparation, procedural setting, and indication was performed.Results: Patients who received propofol-mediated sedation were more likely, and in a dose-dependent manner, to have an enhanced polyp-detection rate (22.8% vs 20.9%, P<0.001), cecal intubation rate (90.4% vs 87.3%, P<0.001), and terminal ileum-intubation rate (6.4% vs 1.6%, P<0.001). On multivariate analysis, these findings were maintained, as propofol-mediated sedation use was significantly associated with improved colonoscopy indicators.Conclusion: Propofol-mediated sedation during colonoscopy is associated with better examination performance and improved outcomes. Further prospective or randomized trials to support these findings are warranted. Keywords: cecal intubation rate, colonoscopy, polyp-detection rate, propofol-mediated sedation, quality indicators
