Summary

This study tests whether a non-invasive device that stimulates nerves in the ear can improve bowel cleansing before a colonoscopy. About 270 adults scheduled for colonoscopy will receive either the real device or a sham version. The goal is to see if this approach leads to better bowel prep quality, higher polyp detection, and fewer side effects.
