Registration Number
NCT02618564
Lead Sponsor
Queen's University
Brief Summary

The objective of this study is to evaluate sennosides as an adjunct to sodium picosulfate magnesium citrate (Pico Salax) in preparation for colonoscopy. We will compare different doses and administration times. The primary outcome is number of bowel motions produced. Secondary outcomes include the quality of bowel cleansing and patient tolerability.

Detailed Description

We will compare different doses and administration times in patients booked for morning colonoscopy. The primary outcome is number of bowel motions produced in total by the sennosides. Secondary outcomes include the quality of bowel cleansing and patient tolerability.

Primary Outcome Measures
NameTimeMethod
Bowel movements, as measured by patient diary2 days

The primary outcome of this pilot study is the number of bowel movements. Patients will record the timing and number of bowel motions produced.

Secondary Outcome Measures
NameTimeMethod
Colon cleansing, as measured by The Ottawa Scale and Aronchick Bowel Cleansing Scale2 days

The secondary outcome is colon cleansing efficacy. The endoscopist will grade the cleansing quality of the colon using two standardized measures - the Ottawa Scale and the 5-point Aronchick Bowel Preparation Scale

Tolerability, as measured by patient questionnaire2 days

The secondary outcome is patient tolerability. Patients will be asked to complete a questionnaire examining symptoms such as nausea, bloating, vomiting, and abdominal pain.
