NCT01415687

Brief Summary

The objective of this study is to compare the efficacy, safety and tolerability of two bowel preparations for colonoscopy - split dose Polyethylene Glycol-Based Lavage and Pico-Salax plus Bisacodyl - with a specific emphasis on the right colon cleanliness. The primary outcomes will be 1) quality of preparation in cleansing the colon, 2) quality of preparation in cleansing the right colon, 3) patient satisfaction. The secondary outcomes will be 1) duration of bowel preparation, 2) patient discomfort during bowel preparation.

Outcome Measures

Primary Outcomes (1)

  • Quality of Bowel Cleanliness

    Ottawa bowel Prep scale will be done by the Dr. to assess the quality of bowel cleanliness. The right, mid and rectosigmoid colon are each rated on a 5-point scale (0-4). Also, a complete 3-point rating for overall colonic fluid is assessed giving an overall score range of 0-14. An excellent preparation would score 0-1; a good preparation, 2-4; while scores \>4 would indicate progressively worsening bowel preparations. A completely unprepared colon would score 11-14, depending on the amount of fluid. A simplified overall cleanliness score will be completed and compared to the Ottawa scale.

    Scales provided to physician at time of colonoscopy, and filled out and collected after procedure is completed (1 hour time). Questionnaires are manually entered by an assistant into the study database on the same day as collection.

Secondary Outcomes (1)

  • Patient Satisfaction with preparation

    Questionnaire given on day of pre-screen and collected on day of colonoscopy, approximately 3 weeks.Patients are not followed or contacted past the day of colonoscopy.

Study Arms (2)

PEG Arm

ACTIVE COMPARATOR

Patients randomized to this arm of the trial will be following preparation instructions using Polyethylene Glycol-Based Lavage in a split dose format

Drug: Polyethylene Glycol-Based Lavage

Pico-Salax + Bisacodyl Arm

ACTIVE COMPARATOR

Patients randomized to this arm will follow preparation instructions using Pico-Salax preparation plus Biscacodyl in a split dose format

Drug: Pico-Salax (Magnesium Citrate) plus Bisacodyl

Interventions

Split dose Polyethylene Glycol-Based Lavage (2L + 2L) If arrival for colonoscopy is prior to 10AM: at 12 noon on the day before your colonoscopy drink 2L of PEG within two hours. At 8PM that day, drink the remaining 2L of PEG within two hours. If arrival for colonoscopy is at or after 10AM: at 8PM on the day before your colonoscopy, drink 2L of PEG within two hours. Starting five hours before your arrival time at the Centre on the day of your colonoscopy, drink the remaining 2L of PEG within two hours.

Also known as: Colyte
PEG Arm

If arrival for colonoscopy is prior to 10AM: 2 tablets Dulcolax at 8PM three days before colonoscopy, 2 tablets Dulcolax at 8PM two days before colonoscopy, and on the day before colonoscopy at 12 noon, drink the first packet of Pico-Salax in 8oz water, and the second packet of Pico-Salax in 8oz of water at 8PM. Day of colonoscopy, drink clear fluids. If arrival for colonoscopy is at or after 10AM: 2 tablets Dulcolax at 8PM three days before colonoscopy, 2 tablets Dulcolax at 8PM two days before colonoscopy, and on the day before colonoscopy at 8PM, drink the first packet of Pico-Salax in 8oz water. Day of colonoscopy, drink the second packet of Pico-Salax in 8oz water five hours before you are to arrive at the Centre.

Also known as: Pico-Salax or Magnesium Citrate, Bisacodyl is also known as Dulcolax.
