NCT ID NCT07261319
First seen Jan 05, 2026 · Last updated Jun 22, 2026 · Updated 33 times
Summary
This study tests whether adding a transparent cap to the tip of a colonoscope helps doctors find more polyps (adenomas) in the lower part of the colon during a second look. About 614 adults aged 45 to 75 will be randomly assigned to get either a standard second exam or one with the cap. The goal is to see if the cap improves detection rates and reduces missed polyps.
