Abstract

OBJECTIVE: To determine whether obstetric outcomes differ between women with endometriosis and those without, where all women undergo first trimester screening for endometriosis DESIGN: A prospective observational cohort study SETTING: The Early Pregnancy Unit at University College London Hospital, United Kingdom SUBJECTS: Women with a live pregnancy progressing beyond 12 weeks’ gestation and concurrent endometriosis (n=110) or no endometriosis (n=393). EXPOSURE: All women underwent a pelvic ultrasound examination in early pregnancy to examine for the presence of endometriosis and uterine abnormalities. MAIN OUTCOME MEASURES: The primary outcome of interest was preterm birth, defined as delivery before 37 completed weeks’ gestation. Secondary outcomes included late miscarriage, antepartum haemorrhage, placental site disorders, gestational diabetes, hypertensive disorders of pregnancy, neonate small for gestational age, mode of delivery, intrapartum sepsis, postpartum haemorrhage and admission to the neonatal unit. RESULTS: Women with a diagnosis of endometriosis did not have statistically significantly higher odds of preterm delivery (aOR 1.85 (95% CI 0.50-6.90)), but they did have higher odds of postpartum haemorrhage during Caesarean section (aOR 3.64 (95% CI 2.07-6.35);) and admission of their newborn baby to the neonatal unit (aOR 3.24 (95% CI 1.08-9.73);). Women with persistent or recurrent deep endometriosis after surgery, also had higher odds of placental site disorders (aOR 8.65 (95% CI 1.17-63.71);) and intrapartum sepsis (aOR 3.47 (95% CI 1.02-11.75);). CONCLUSION: We observed that women with endometriosis do not have higher odds of preterm delivery, irrespective of their disease subtype. However, they do have higher odds of postpartum haemorrhage during Caearean section and newborn admission to the neonatal unit.
