Re-examining the entire colon enhances polyp detection rates.

A randomized controlled trial involving 406 patients demonstrated that re-examination of the entire colon significantly improves the detection of concealed polyps and adenomas compared to standard colonoscopic methods. While polyp detection rates were generally similar between the study and control groups, the second withdrawal significantly increased the number of detected polyps and adenomas. These findings suggest that a comprehensive re-examination strategy can effectively mitigate the risk of interval cancers in patients.
