Improving Outcomes for Patients Requiring Oral Bowel Preparation for Colonoscopy

Improving Outcomes for Patients Requiring Oral Bowel Preparation for Colonoscopy

Study hypothesis The overall aim of this study is to compare two bowel preparations that are used prior to a colonoscopy procedure.

The principal research questions are:

1. Does the use of a low residue diet increase patient concordance to the bowel preparation instructions?
2. Does the use of a low residue diet decrease the adequacy of assessment of the mucosa?
3. Does the use of a low residue diet increase the willingness of patients to undertake repeated examination as is required for disease follow-up?
4. Does body weight affect perceived tolerability of either group?
