Summary

This pilot trial tests a special irrigation solution—made with peppermint oil and other ingredients—to see if it improves visibility during colonoscopy. The solution is sprayed into the colon during the procedure to reduce bubbles, spasms, and improve the view of the lining. The study involves 35 patients aged 45-75 undergoing screening colonoscopy, and doctors will rate how well the solution works. If successful, it could lead to a larger study and potentially more comfortable, effective colonoscopies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A novel irrigation solution made of sterile water mixed with peppermint oil, tween, indigo carmine, and simethicone, used during colonoscopy.
What this could lead to
If it works, this solution could make colonoscopies clearer and more comfortable, potentially improving detection of polyps and reducing procedure time.
What could go wrong
This is a small early-stage pilot, so results may not hold up in larger studies. The solution includes peppermint and blue dye, which could cause allergic reactions in some people.

Patient Inclusion Criteria: 1. Between 45 to 75 years of age 2. Currently receiving gastroenterology or primary care at NYU Langone Hospital 3. Capacity and willingness to provide consent 4. Undergoing a screening colonoscopy Provider Inclusion Criteria: 1. Faculty gastroenterologist at NYU Langone Ambulatory Care Center 2. At least 18 years of age 3.
