Abstract
ObjectiveTo investigate the qualified rate of bowel preparation for colonoscopy and its influential factors in patients undergoing colonoscopy, so as to provide relevant reference for clinical diagnosis and treatment.
MethodsA total of 158 patients who underwent colonoscopy in the Endoscopy Center of the Second Affiliated Hospital of Wenzhou Medical University from May to October 2019 were included in this study. Boston Bowel Preparation Scale (BBPS) was used to evaluate the bowel preparation status for colonoscopy, and the qualified rate of bowel preparation and its influential factors were analyzed.
ResultsThe qualified rate of bowel preparation was 72.15% (114/158), and the BBPS score was 5.86 ± 1.17. Univariate analysis showed that education level,history of constipation,active exercise after taking medicine, exercise habit, time interval between taking medicine and first defecation, defecation frequency after taking medicine, whether taking medicine compliantly, time interval between taking medicine and examination, shape of feces at the last time, dietary intake 1 day before examination affected the qualified rate of bowel preparation [χ2(t) = 5.572, 12.326, 17.135, 7.646, 15.107, 6.826, 11.114, 12.294, 11.063, 17.625, all P<0.05]. Logistic multivariate regression analysis showed that long time interval between taking medicine and first defecation, low defecation frequency after medication, no compliant medication, long time interval between medication and examination,residue-like or yellow watery stool at the last time, and a high-fiber diet 1 day before examination were the independent risk factors of low qualified rate of bowel preparation (OR = 2.917, 2.091, 8.527,3.184, 10.111, 2.134, all P<0.05).
ConclusionThe qualified rate of bowel preparation in patients undergoing colonoscopy is not high, and BBPS score is very low. A variety of independent risk factors affect the quality of bowel preparation and decrease the qualified rate of bowel preparation. Targeted measures should be taken to improve the quality of bowel preparation.
