  Purpose

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.

Primary Outcome Measures:
  • To assess which bowel preparation provides the best colon cleansing using a validated score and is best tolerated by patients. [ Time Frame: At time of colonoscopy ]

Secondary Outcome Measures:
  • To assess the incidence of mucosal inflammation/ulceration induced by each colon cleansing agent. [ Time Frame: At time of colonscopy ]

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • All patients who are referred to undergo ambulatory colonoscopy at Kaleeya Hospital would be entered into the study

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.
