A Prospective Study Comparing Oral Sodium Phosphate Solution to a Bowel Cleansing Preparation with Nutrition Food Package in Children

Abstract

The inability of children to comply with bowel preparation regimens can result in inadequate visualization of the colon. This study compares the safety, efficacy, and patient acceptance of a prepackaged diet kit plus a magnesium citrate/bisacodyl bowel cleansing regimen with a clear liquid diet and sodium phosphate solution regimen in children undergoing colonoscopy. Children scheduled for a diagnostic colonoscopy, were randomly assigned to receive a prepackaged diet kit and a magnesium citrate/bisacodyl laxative (group 1), or clear liquids and sodium phosphate solution (group 2). The patients and their parents completed a questionnaire to evaluate acceptance of their assigned regimen before colonoscopy. The endoscopists, blinded to the type of bowel preparation, rated bowel cleansing. Sixty two children (28 males, 34 females) with mean age 12.5 years participated. Thirty six and 26 patients were in groups 1 and 2 respectively. Overall cleansing was rated significantly superior in group 1 compared to group 2 as was amount of retained feces (P = .013 for both). The overall frequency of reported side-effects was lower in group 1 than (83.3%, 30/36) than in group 2 (100.0%, 26/26) (P = 0.03). The preparations were otherwise equivalent in regards to compliance and patient tolerance. Although both regimens were comparable in adequacy of colon visualization, preparation tolerance, side effects and compliance profile in this pilot study, the prepackaged diet kit with magnesium citrate/bisacodyl laxative resulted in superior colon cleansing.
