Novel Colon Preparation Method Combining Bowel Cleanser Reduction and Unique Walking

Abstract

Background and Purpose: Poor bowel preparation increases the difficulty of colonoscopy and affects lesion detection. In this study, we investigated the usefulness of a new bowel preparation method using polyethylene glycol electrolyte formulation containing ascorbic acid (PEG plus ascorbic acid: PEG-Asc, MOVIPREP) to improve bowel cleansing and shorten preparation time. Methods: This was a single-center, retrospective study. In the new method, patients were instructed to take a laxative the day before the examination and PEG1L on the day of the examination. In addition, we instructed the patients to walk, which we designed. The primary endpoints were the degree of bowel cleansing (assessed by the Boston bowel preparation scale, BBPS) and time to the cecum. Results: The conventional group reached the cecum in 606.5±225.8 seconds (mean±SD), whereas the introduced group reached the cecum in 500±217.1 seconds, a significantly shorter time (P<0.05). In the BBPS, the score in the introduced group was significantly higher (P<0.01): 6.8±2.14 points in the conventional group and 8.6±0.74 points in the introduction group. Conclusion: Pretreatment combining the 1L weight loss method and walking improves bowel cleansing and shortens the time to reach the cecum.
