Comparison of Whole versus Split-Dose PEG Solution for Colonoscopy Preparation on Patient Compliance, Quality of Bowel Cleansing, and Endoscopist's Satisfaction / 성인간호학회지

ABSTRACT

PURPOSE: This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction. METHODS: The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming 2 liter of PEG solution twice, or a whole-dose group(n=30), consuming 4 liter of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS. RESULTS: The participants who did not completely consume 4 liter of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups. CONCLUSION: Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.
