Water Exchange Improves Detection of Advanced Colorectal Neoplasia: Pooled Analysis of Four Randomized Trials.

Key Points

• This research aims to evaluate the effectiveness of water exchange colonoscopy in detecting advanced colorectal neoplasia compared to standard air insufflation.
• Conducted a pooled analysis of four randomized controlled trials (RCTs)
• Compared outcomes from water exchange colonoscopy and air insufflation
• Focused on detection rates of advanced colorectal neoplasia, particularly in the proximal colon.
• Water exchange colonoscopy significantly improves detection of advanced colorectal neoplasia overall
• Increased detection rates were noted particularly in the proximal colon compared to air insufflation
• Further studies are needed to explore the implications for interval colorectal cancer risk.
