Study on the correlation between endometriosis and adverse pregnancy outcomes

Abstract

ObjectiveThis study aims to investigate the correlation between endometriosis (EMS) and adverse obstetric outcomes. MethodsIn this retrospective study 2,925 cesarean section cases were analyzed at the Women and Children’s Hospital of Ningbo University, Department of Obstetrics, between May 2019 and December 2023. The study included 1,363 women diagnosed with endometriosis during pregnancy at the time of surgery (study group) and 1,562 women without such a diagnosis (control group). The comparative assessment covered the age of first-time mothers, number of pregnancies and births, gestational age at delivery, incidence rates of assisted reproductive technology (ART), spontaneous abortion, preterm birth, placenta previa, placental adhesion, and postpartum hemorrhage. ResultsThe study group demonstrated a higher average age of first-time mothers, fewer pregnancies and births, and a significantly shorter gestational age at delivery (P < 0.05) compared to the control group. Incidences of primary infertility, spontaneous abortion, and ART utilization were higher in the study group. The occurrence of placenta previa, placental adhesion, and postpartum hemorrhage was also higher in the study group, indicating significant statistical differences (P < 0.05). No significant difference was observed in preterm birth rates between the groups (P > 0.05). ConclusionPregnancy in women with endometriosis is associated with a higher likelihood of adverse outcomes, therefore highlighting the need for increased clinical awareness.
