Summary

This trial compares three different bowel-cleansing regimens for adults who need a repeat colonoscopy because their first prep didn't work well enough. Participants are randomly assigned to take one of three laxative combinations before their second colonoscopy. The study measures how clean the bowel gets and how satisfied patients are with the process.

What this could lead to

If successful, this study could identify the most effective rescue bowel preparation, making repeat colonoscopies easier and more reliable for patients who had a failed prep.

What could go wrong

This is a small, single-center trial (220 participants) comparing existing drugs, not a new breakthrough. Results may not apply to all patients or settings.
