B-CLEAN: The Bowel CLEAnsing: A National Initiative
Study Details
Study Description
Brief Summary
The purpose of this study is to compare diet, type of bowel preparation and time of colonoscopy to determine if one method is better than the other and, if they are the same, identify the one which is the most convenient for the patients.

Phase 4 |
Detailed Description
The objective of the current proposed trial is thus to compare the cleanliness achieved with PEG high-volume (2L+2L) split-dose versus PEG (1L+1L)+Bisacodyl low-volume split-dose, or PEG high volume (4L) non-split day before versus PEG low volume (2L) non-split same day preparation, according to time of endoscopy (early or later), as well as assess the role of diet (low residue or clear liquid diet) according to these different Canadian outpatient preparation regimens.

Active Comparator: 1) Early colonoscopy; 2) High-dose, split-dose; 3)Clear liquid
|
Drug: High volume PEG split-dose
Colyte® or PegLyte® will be provided to the subject who will be asked to drink 2L of the preparation starting at 7:00 PM the day before the procedure at a rate of 240 mL every 10 minutes until completed. The second dose of 2L of preparation will be taken the morning of the colonoscopy starting 4-5 hours prior to the planned procedural time at a rate of 240 mL every 10 minutes until completed.

Bi-PegLyte® will be provided to the subject who will be asked to ingest 3 tabs of Bisacodyl 5 mg (total 15 mg) at 2:00 PM the day before the procedure. After the first bowel movement, or if there is no bowel movement within 6 hours of taking the Bisacodyl tablets, the subject will be asked to drink 1L of the solution at a rate of 240 mL every 10 minutes until the solution is completed. The second dose of 1L of preparation will be taken the morning of the colonoscopy starting 4-5 hours prior to the procedure at a rate of 240 mL every 10 minutes. Use of antacids will not be permitted within one hour of taking bisacodyl.
