Study Details

Study Description

Brief Summary

The purpose of this study is to compare Nulytely (or Trilyte) with a Gatorade and Miralax combination for cleaning out the colon before colonoscopy. A laxative pill called Bisacodyl may also be used with the Gatorade and Miralax to see if it helps with the clean out process. We are trying to find out if either of these methods is more acceptable to the patient and does a better job cleaning out the colon for a colonoscopy.

Outcome Measures

Primary Outcome Measures

  1. The Quality of the Colon Preparation Will be Graded Using the Boston Bowel Preparation Scale [After Colonoscopy]

    The Boston Bowel Preparation Scale measures cleanliness of the colon on a scale of 0 (very poor) to 9 (excellent).

Secondary Outcome Measures

  1. The Ottawa Scale for Colonoscopy Preparation Will be Reported and Compared Among the 3 Groups to Allow for Comparisons to Some of the Older Literature [After Colonoscopy]

    Ottawa scale measures colon cleanliness on a scale from 14 (very poor) to 0 (excellent).

Study Results

Participant Flow

Recruitment Details Subjects had their colonoscopy performed between February 2010 and February 2011 by one of three gastroenterologists (DG, JH, and MR) with 17 to 34 years of experience. Colonoscopies were scheduled to begin between 0800 h and noon in the gastrointestinal labs at our office or two community hospitals.

Limitations/Caveats

Both the BBPS and OPS suffer from poorly designed scoring systems that are not easily converted into the poor/fair/good/excellent subjective rating scale, which is often used by gastroenterologists in their colonoscopy reports.
