This meta-analysis found age, CA125, cyst size, dysmenorrhea, prior surgery, preoperative medication, and rASRM score are risk factors for endometrioma recurrence, while postoperative pregnancy is protective.

This systematic review and meta-analysis evaluated studies published before October 2020 to identify risk factors for ovarian endometrioma (OMA) recurrence after surgical excision, searching PubMed, Embase, the Cochrane Library, CNKI, and Wanfang and pooling odds ratios or standard mean differences. Across included evidence, recurrence was associated with younger/older age at surgery (SMD −0.28), higher CA125 level (SMD 0.51), larger cyst size (SMD 0.35), dysmenorrhea (OR 1.47), history of endometriosis-related surgery (OR 2.60), pre-operative medication (OR 2.13), and higher rASRM score (SMD 0.33), while post-operative pregnancy showed a protective association (OR 0.22). A key limitation noted in the paper is that the effects of bilateral involvement, coexisting adenomyosis, and post-operative medication on recurrence require further investigation. This paper is centrally about endometriosis — it specifically meta-analyzes predictors of ovarian endometrioma recurrence after excision, directly relevant to endometriosis outcomes.

Abstract

PurposeExploring potential risk factors for OMA recurrence, thereby contributing to the individual management of the disease and improving the patients' prognosis.MethodsData sources PubMed, Embase, the Cochrane Library, CNKI, and Wanfang data were searched systematically before October 2020. We computed the pooled odd ratios or the standard mean difference with their corresponding 95% confidence interval to investigate the impact of involved risk factors on endometrioma recurrence.ResultsThe pooled findings of this meta-analysis demonstrated that endometrioma relapse was closely related to age at surgery [SMD (95% CI):  - 0.28 (- - 0.38 to  - 0.17), P < 0.00001], CA125 level [SMD (95% CI): 0.51 (0.14-0.88), P = 0.007], cyst size [SMD (95% CI): 0.35 (0.08-0.62), P = 0.01], dysmenorrhea [OR (95% CI): 1.47 (1.07-2.02), P = 0.02], endometriosis-related surgery history [OR (95% CI): 2.60 (1.84-3.67), P < 0.00001], pre-operative medication [OR (95% CI): 2.13 (1.41-3.22), P = 0.0003], rASRM score [SMD (95% CI): 0.33 (0.20-0.46), P < 0.00001]. Furthermore, post-operative pregnancy was indicated a protective factor for preventing the OMA recurrence after surgery [OR (95% CI): 0.22 (0.09-0.56), P = 0.001] CONCLUSION: Age at surgery, CA125 level, cyst size, dysmenorrhea, endometriosis-related surgery history, pre-operative medication, rASRM score were risk factors for endometrioma relapse. In addition, post-operative pregnancy was a protective factor for preventing recurrence after surgery. However, the effect of bilateral involvement, combination with adenomyosis, or post-operative medication on endometrioma relapse need further investigations.

Abstract

Purpose Exploring potential risk factors for OMA recurrence, thereby contributing to the individual management of the disease and improving the patients’ prognosis.

Methods

Data sources PubMed, Embase, the Cochrane Library, CNKI, and Wanfang data were searched systematically before October 2020. We computed the pooled odd ratios or the standard mean difference with their corresponding 95% confidence interval to investigate the impact of involved risk factors on endometrioma recurrence.

Results

The pooled findings of this meta-analysis demonstrated that endometrioma relapse was closely related to age at surgery [SMD (95% CI): − 0.28 (- − 0.38 to − 0.17), P < 0.00001], CA125 level [SMD (95% CI): 0.51 (0.14–0.88), P = 0.007], cyst size [SMD (95% CI): 0.35 (0.08–0.62), P = 0.01], dysmenorrhea [OR (95% CI): 1.47 (1.07–2.02), P = 0.02], endometriosis-related surgery history [OR (95% CI): 2.60 (1.84–3.67), P < 0.00001], pre-operative medication [OR (95% CI): 2.13 (1.41–3.22), P = 0.0003], rASRM score [SMD (95% CI): 0.33 (0.20–0.46), P < 0.00001]. Furthermore, post-operative pregnancy was indicated a protective factor for preventing the OMA recurrence after surgery [OR (95% CI): 0.22 (0.09–0.56), P = 0.001]

Conclusion

Age at surgery, CA125 level, cyst size, dysmenorrhea, endometriosis-related surgery history, pre-operative medication, rASRM score were risk factors for endometrioma relapse. In addition, post-operative pregnancy was a protective factor for preventing recurrence after surgery. However, the effect of bilateral involvement, combination with adenomyosis, or post-operative medication on endometrioma relapse need further investigations. Similar content being viewed by others
