Comparing the ADR With Air Insufflation, Water Immersion and Water Exchange During Two-endoscopist Colonoscopy

Adenoma Clinical Trial

Official title:
A Randomized, Controlled Trial Comparing the Adenoma Detection Rate With Air Insufflation, Water Immersion and Water Exchange During Two-endoscopist Colonoscopy

Clinical Trial Summary

Interval (missed) cancers and lower than expected mortality reduction of proximal colon cancers in the United States and elsewhere after screening colonoscopy drew attention to quality indicators. Missed adenomas which are more likely to be in the proximal colon may be contributing factors. An independent predictor of the risk of interval cancers is adenoma detection rate. In pilot observations, the investigators showed that water exchange enhanced adenoma detection in the right colon (cecum to hepatic flexure). This prospective, randomized controlled trial will compare water exchange with water immersion and traditional air insufflation in patients undergoing colonoscopy. The investigators test the hypothesis that compared with air insufflation and water immersion, water exchange produces a significantly higher adenoma detection rate in the right colon
