Clinically Indicated Colonoscopy Clinical Trial
Official title:
A Randomized Controlled Trial Comparing Breakfast Versus no Breakfast
In addition to bowel cleansing agents, the current practice of bowel preparation for
colonoscopy involves a low residue diet 48 hours prior to and a clear fluid diet the day
before the procedure. This study aims to test whether patients who consume a low residue
breakfast the day prior to colonoscopy have a difference in the quality of their bowel
preparation. Patients requiring outpatient colonoscopies will be asked to participate. They
will be randomized to either breakfast or no breakfast the day before the procedure. Colon
cleanliness, patient hunger, and tolerance will be assessed.
The investigators hypothesize that there will be no difference in bowel preparation scores
and will be better tolerated
Colon cleansing prior to colonoscopy is essential for an adequate examination. Research has
shown that preparation prior to colonoscopy remains one of the biggest deterrents for
patients considering colon screening (1).
In addition to the bowel cleansing agents another important aspect of the preparation is the
diet consumed prior to the procedure. Currently 48 hours prior to colonoscopy patients are
asked to consume a low residue diet. The day before the procedure they are switched to a
clear fluid only diet which many patients find difficult to follow due to hunger and can
lead to non-compliance with the preparation.
There have been no trials to date which have answered the question whether the consumption
of breakfast alters colon cleansing with the cleansing agents currently used in Canada.
Investigators found that in patients receiving sodium phosphate preparations, a full
breakfast or low residue lunch had no effect on colon cleansing scores and improved hunger
and energy levels (2). Several studies have looked at the result of low residue diet kits
taken the day prior to the procedure and showed no difference in colon cleansing or
tolerability compared to the traditional clear fluid regime (3,4).
This study aims to test whether patients who consume a low residue breakfast the day prior
to colonoscopy have a difference in the quality of their colon cleansing or tolerability of
the preparation compared to those who consume a clear fluid diet. The investigators
hypothesize that there will be no difference in bowel preparation scores and will be better
tolerated.
