Brief Summary:
Poor or inadequate bowel preparation is one of the most common reasons for a repeated or failed colonoscopy. Preparation methods shown to be effective include the use of either bowel-cleansing devices or oral laxatives. Despite the acceptable effectiveness and safety of both bowel-cleansing methods, very few studies have been performed to evaluate which method is more effective. The main aim is to perform an observational study followed by propensity score modeling to evaluate and compare the quality of bowel preparation with the use of Aquanet bowel-cleansing devices versus the use of oral Sodium picosulfate solution. The study will involve 314 patients requiring a colonoscopy, between 14 and 90 years of age and with more than three bowel movements per week for the past one month. Outcomes of interest being the quality of bowel preparation evaluated through the Boston Bowel Preparation (BBP) scale. The investigator hypothesized that the bowel preparation with Aquanet bowel-cleansing device for colonoscopy will provide a better outcome for the patient than with conventional methods.

Arm Intervention/treatment
Active Comparator: Sodium Picosulfate solution (Picoprep)
On the eve of the examination, all participants on Sodium picosulfate will take four tablets of Dulcolax with tea or water in the morning, liquid diet (juice, tea or water) at lunch, two capsules of 25mg Dramamine Capsgel in the afternoon, Sodium picosulfate dissolved in 150mL of cold water thirty minutes after, followed by drinking at least five 250-ml cups of water or other light liquids until midnight, with absolute fasting up to the time when the colonoscopy will be performed.
Drug: Sodium Picosulfate
Sodium Picosulfate solution (Picoprep)

Experimental: Aquanet bowel cleansing devices
For bowel preparation with the bowel cleansing device, intestinal lavage will be performed with the device, making use of water, pressure, and gravity to enhance bowel cleansing. The water used in this procedure was previously triple-filtered by passage on carbon, micro-pellets and ultraviolet light. The preparation will be carried out by a trained nurse.
Device: Aquanet

Primary Outcome Measures :
  1. Quality of bowel preparation [ Time Frame: 16 weeks ]
    Evaluated through the Boston Bowel Preparation (BBP) scale.
