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.

Condition or Disease Intervention/Treatment Phase
  • Drug: High volume PEG split-dose
  • Drug: Low volume PEG split-dose
  • Drug: High volume PEG non split, day before
  • Drug: Low volume PEG non split, same day
  • Other: Clear liquid diet
  • Other: Low residue diet
  • Other: Early colonoscopy (stratified)
  • Other: Later colonoscopy (stratified)
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.
