Abstract : Introduction: Critical component of a successful colonoscopy is adequate bowel preparation. Inadequate preparation has negative effects on both the community as a whole and individuals. Objective We aimed to determine the effect of poor bowel preparation on patient willing’s to repeat colonoscopy. Patients and methods of 122 patients undergoing colonoscopy in Minia university hospital was conducted between June 1, 2021, and June 1, 2022. All data were analyzed using SPSS, version 18.0. Results A total of 122 outpatients were enrolled in the study. They were divided into two equal groups according to the degree of bowel preparation: good and very good bowel preparation (group 1, n= 96), and poor bowel preparation (group 2, n=26). Baseline characteristics, were comparable between the two groups. Of the 122 colonoscopies, cecal intubation failed in 7 cases of 96 of (group 1) (7.3%) and failed in 23 cases of 26 of (group 2) (88.5%); with a significant difference (p= 0.001). Pain severity and anxiety score was significantly higher in group 2 than group 1 (p=0.0001There is a statistically significant difference in the mean (SD) score for willingness to accept to repeat colonoscopy between groups 1 and 2 (6.29±1.44 vs 2.7± 1.3; P = 0.001). Conclusion Poor bowel preparation not only had a significant association with cecal intubation failure rate but also it decreases the patient willingness to repeat the examination.
