Abstract
INTRODUCTION: This study aimed to examine the association between chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and receipt of a prior colonoscopic examination using a population-based database. METHODS: We used the Taiwan Longitudinal Health Insurance Database 2005 to retrieve the study sample. This study included 3933 patients with CP/CPPS and 3933 age-matched controls. We designated the date of receiving the first diagnosis of CP/CPPS as the index date for cases. We defined the first an ambulatory care visit occurring in the matched year as the index date for the controls. Conditional logistic regressions was used to calculate the odds ratio (OR) and 95% confidence interval (CI) for having previously received colonoscopy between cases and controls. RESULTS: We found that 349 (4.44%) of the 7866 sampled patients had previously undergone colonoscopy, including 223 (5.67%) cases and 126 (3.20%) controls (p<0.001). A conditional logistic regression analysis revealed that the adjusted OR of receiving a colonoscopy within three years before the index date was 1.77 (95% CI 1.42-2.23) for cases compared to controls. Furthermore, we found that the youngest group of cases (<40 years) had the greatest adjusted OR for having received colonoscopy within three years before the index date compared to controls (OR 2.81; 95% CI 1.45-5.44); however, in contrast, no significant difference in the adjusted odds of having previously received colonoscopy was observed between cases and controls among the oldest age group (≥60 years). CONCLUSIONS: We concluded that there was an association between antecedent colonoscopy and CP/CPPS.
