Comparison of two bowel cleansing regimens in patients with subsequent colonoscopy

For successfull detection of premalignant colorectal lesions appropriate bowel preparation is a gold standard. The aim of this study was to compare two bowel cleansing regimens. Adult out-patients who received colonoscopy were included in the study from Sep 1 2020 to Nov 30 2020. Patients were divided two groups: first received 4–L split dose sodium picosulfate regimen, second – 4-L unsplit dose polyethylene-glycol (PEG). To describe colon cleanness Boston Bowel Preparation Scale (BBPS) was used. Poor cleanness were defined as total BBPS score from 1-3, medium- from 4 - 6, good- from 7-9. Patients were also divided: under and over 50 yo. Data was pooled and analyzed using IBM SPSS 22.0. In total, 449 patients – 61,2 % female and 38,8 % male, patients aged 16 – 87, with the mean age of 47,38 +/- 14,21 were enrolled in the study. 160 (65,4 %) were preparing with first regimen, 67 (27,6 %) were preparing with PEG. First regimen medium BBPS score were 7,24 +/- 1,498, PEG medium BBPS score were 6,33 +/- 1,330. First regimen total BBPS 1 - 3 were 6, 3,7 %, 4 – 6 were 27,16,9 %, 7 – 9 were 127, 79,4 % . PEG total BBPS 1 – 3 were 3, 4,5 %, 4 – 6 were 35, 52,5 % , 7 – 9 were 29, 42 %. Patients under age 50 median BBPS were 6,60 +/- 1,538, patients over age 50 median BBPS were 6,36 =/- 1,383. Using Pearson corellation analyze, was concluded, that between age and BBPS exists negative and stastistical significant corellation. (r = - 0.108; p= 0.024, p< 0.05). Medium BBPS is higher in patients,who received 4 L split dose sodium picosulfate. Between age and BBPS exists negative and statistical significant corellation.
