摘要
Colonoscopy is an effective method for screening colorectal cancer and adenoma, but the adenoma detection rate depends on the quality of bowel preparation. Our study investigates the influencing factors of the quality of bowel preparation before colonoscopy in outpatients and the influence of the number of walking steps on the quality of bowel preparation. We prospectively collected the clinical data of 150 outpatients undergoing colonoscopy in our department in 2019. Ordinal logistic regression shows that the overweight, not drinking, the number of walking steps before colonoscopy, and the time interval between start PEG and colonoscopy (4–6 hours) were independent factors affecting bowel preparation quality. There was a curving relationship between the reciprocal of Ottawa score and the number of walking steps before colonoscopy, and the regression equation is 1/ Ottawa score = −0.198 + 0.062 × ln steps ( p = .035), a minimum of 5,270 walking steps before a colonoscopy is required for a high quality of bowel preparation.
