Plain-language summary
Colonoscopy is the most useful exam used to evaluate colorectal diseases, like colorectal polyps and cancer. The appropriate bowel preparation is indispensable for colonoscopy procedures. Polyethylene glycol solution (PEG) is the most frequent laxative medication. However, the taste is poor, and patients need to drink a lot of liquids to obtain adequate visualization of the mucosal surface. In fact, no laxative has all the characteristics of an ideal medication. Lactulose is an osmotic laxative which widely used in cirrhosis and constipation patients, and could inhibit bacterial in the colon to increase colon cleanliness and prolong the effect time of PEG. Previous study demonstrate PEG combined with lactulose has a significant improvement in the quality of bowel preparation compared with PEG alone. The present study aim to assess the efficacy of lactulose with or without PEG in bowel preparation to improve mucosal visualization, reduced volume of fluid consumed, and preparation intolerance.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
