Abstract
Introduction:
Previous studies have linked chronic pelvic pain (CPP) to appendix pathologies. However, few studies have investigated appendix pathology specifically in the context of CPP that is right-side predominant (R-CPP). We hypothesized that women with R-CPP have higher rates of appendix pathology compared with women with CPP that is not right-side predominant (N-CPP).
Methods:
We conducted a retrospective case–control study of 220 women who underwent diagnostic laparoscopy and planned or incidental appendectomy for CPP and suspected endometriosis between January 2015 and December 2018 at a tertiary care center in Saint Louis, MO.
Results:
No significant difference in abnormal appendix pathology was found between women with R-CPP and women with N-CPP (30.9% vs 34.5%, p = 0.74, odds ratio = 0.85, 95% CI: (0.44, 1.62)). Gross abnormalities of the appendix were documented in 40 of 220 patients (18.2%), with the most common abnormal gross findings being adhesions (8.2%), followed by abnormal lesions (7.3%).
Conclusion:
In this study, the presence of abnormal pathology within the appendix did not correlate with R-CPP, indicating triage based on predominant pain location cannot help identify patients with underlying appendix pathology. However, consistent with previous studies, we identified a high rate of abnormal appendix pathology overall, supporting the practice of many surgeons to perform routine appendectomy in women with CPP.
