Association between endometriosis and perinatal complications: a case-control study

Area of Science:

• Reproductive Medicine
• Obstetrics
• Gynecologic Surgery

Background:

• Endometriosis is increasingly linked to adverse perinatal outcomes.
• The impact of pre-pregnancy endometriosis treatment on these complications remains unclear.
• This study investigates the association between endometriosis and placenta previa, considering surgical intervention.

Purpose of the Study:

• To determine if a history of endometriosis is an independent risk factor for placenta previa.
• To assess the influence of surgical endometriosis treatment on placenta previa incidence.

Main Methods:

• A case-control study of 2781 deliveries (133 with endometriosis, 2648 without).
• Comparison of perinatal outcomes using statistical tests (t-test, Fisher's exact test).
• Logistic regression analysis to identify risk factors for placenta previa and evaluate surgical impact.

Main Results:

• A history of endometriosis significantly elevates the risk of placenta previa (adjusted OR, 2.30).
• Complete surgical treatment for advanced (Stage III-IV) endometriosis was associated with a lower placenta previa incidence (5.9% vs. 33.3%).

Conclusions:

• Endometriosis history is an independent risk factor for placenta previa.
• Complete surgical management of advanced endometriosis may mitigate placenta previa risk.
• Further research is warranted to confirm the benefits of endometriosis surgery on perinatal complications.
