First seen Jan 05, 2026 · Last updated Apr 25, 2026 · Updated 20 times

Summary

This study tests whether using a transparent cap on the colonoscope during a second look at the lower part of the colon helps doctors find more polyps (adenomas). About 614 adults aged 45 to 75 will be randomly assigned to either a standard second exam or one with the cap. The goal is to see if the cap improves detection rates without changing the usual procedure.
