CompletedPhase 4
Bowel Preparation for Colonoscopy in the Elderly
South Korea230 participantsStarted 2014-11
Plain-language summary
The success of colonoscopy is closely related to the quality of colonic preparation. However, data regarding colonoscopy preparations in the elderly (65 years older) are scarce. Split-dosage cathartic bowel preparation are currently suggested, whereas supporting evidence is lacking in this particular group of patients. Moreover, patient tolerability is a key factor for success of bowel preparation in the aged people.
The purpose of this study is to compare the bowel cleansing efficacy and patient compliance of following bowel preparation methods prior to elective outpatient colonoscopy in the elderly: (1) standard preparation of 4 liters (L) PEG-3350 solution on the night before colonoscopy, (2) split-dose of 4L PEG-3350 solution, and (3) split-dose of reduced volume \[2L\] PEG-3350 containing ascorbic acid solution.

Inclusion Criteria:
* elderly people aged over 65 years

* informed consent
Exclusion Criteria:
* patients who had bowel movements of less than 3 per week during last one month
* patients who have a history of renal dysfunction (abnormal elevation of serum creatinine and electrolyte imbalance)
* patients who have a history of alimentary tract surgery
* patients who have other gastrointestinal diseases that are not suitable for undergoing colonoscopy (gastroparesis, gastric outlet obstruction, ileus, ischemic colitis, megacolon, and toxic colitis)

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Proportion of adequate bowel preparation quality at the time of colonoscopy defined by the Boston bowel preparation scale (BBPS).
