Study of Efficacy and Tolerability of Various Bowel Preps in Diabetic Patients

This study is ongoing, but not recruiting participants.
Sponsor:
Information provided by (Responsible Party):
University of Oklahoma
ClinicalTrials.gov Identifier:
NCT01533688
First received: January 19, 2012
Last updated: March 24, 2017
Last verified: March 2017
  Purpose
Poor bowel preparation and patient intolerance of the procedure are the most important factors contributing to the limitation of colonoscopy. Inadequate bowel cleansing results in incomplete testing, increased potential to miss lesions, increased cost, and decreased patient satisfaction. The investigators hope to gain better insight into which bowel preparation works best in diabetic patients and hence would increase patient satisfaction, tolerability of the bowel preparation and decrease overall costs. The investigators will investigate which bowel preparation for colonoscopy will work optimally in diabetic patients using three different regimens.

Condition Intervention
Diabetes Mellitus Drug: Golytely (polyethylene glycol electrolyte lavage solution) and placebo Drug: split dose of Golytely (polyethylene glycol electrolyte lavage solution) + placebo Drug: split dose of Golytely (polyethylene glycol electrolyte lavage solution) and bisacodyl

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Investigator
Primary Purpose: Diagnostic
Official Title: Efficacy and Tolerability of Various Bowel Preparations in Diabetic Patients: A Randomized Controlled Trial

Primary Outcome Measures:
  • Measure the % of participants with effective (how well the colon is cleansed using the validated Boston Bowel Preparation Scale) for various bowel preparations for colonoscopy. [ Time Frame: Day 1 ]
    The investigators will measure the number/% of participants who will have good to excellent bowel preparations defined by the Boston Bowel Prep Scale(BBPS) with a score of 7 or more, rated by blinded colonoscopist.


Secondary Outcome Measures:
  • Measure of patients who develop (tolerance)side effects of taking bowel preparations. [ Time Frame: 24 hours ]
    Tolerability of the bowel prep will be measured by the number/% of participants with adverse events(i.e. nausea,vomiting, abdominal pain, bloating or rectal burning sensation) using a survey.
