A Patient-Blinded Randomized, Controlled Trial Comparing Air Insufflation, Water Immersion, and Water Exchange During Minimally Sedated Colonoscopy

Abstract

This head-to-head comparison of AI vs. WI vs. WE confirmed that WE was superior to WI and AI, with a significantly greater proportion of patients reporting painless insertion. The significantly higher ADR in the right colon in the WE group warrants further investigations.
