Outcomes
Primary outcome [1] 0 0
To assess which bowel preparation provides the best colon cleansing using a validated score and is best tolerated by patients.
Timepoint [1] 0 0
At time of colonoscopy
Secondary outcome [1] 0 0
To assess the incidence of mucosal inflammation/ulceration induced by each colon cleansing agent.
Timepoint [1] 0 0
At time of colonscopy

Eligibility
Key inclusion criteria
- All patients who are referred to undergo ambulatory colonoscopy at Kaleeya Hospital
would be entered into the study
Minimum age
18 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
- Prior history of inflammatory bowel disease or suspected inflammatory bowel disease,
or patients on current non steroidal antiinflammatory medication (excluding low dose
aspirin). These patients may have mucosal inflammation/ulceration which would prevent
analysis of mucosal abnormalities due to the colon cleansing agent and so would not be
studied.

- Patients with heart failure (NYHA >2) or renal failure (GFR<30) (since fluid shifts
associated with sodium phosphate bowel preparation have been reported).

- All patients over the age of 75 due to potential dehydration and hyperphosphatemia
from the bowel preparations.

Summary
Brief summary
Colonoscopy is the gold standard investigation for assessing the lining of the colon. Colon
cleansing preparations are required to be taken prior to colonoscopy to provide effective
visualisation and identification of any abnormalities and different types of colon cleansing
preparations exist.

Some colon cleansing preparations have been shown to cause visible changes in the lining of
the bowel which may cause confusion and incorrect diagnoses to be made.

This audit aims to assess the ability of different colon cleansing preparations to clear the
colon of faeces. The tolerability of each will also be assessed, as will any changes in the
lining of the bowel to assess if one type of colon preparation is more likely to cause
visible changes than another.
