Obstetric and perinatal outcomes in women with endometriosis

Key content Endometriosis in pregnancy is associated with an increased risk of spontaneous miscarriage, pre‐eclampsia, postpartum haemorrhage, caesarean section, placenta praevia, fetal growth restriction, prematurity and adverse neonatal outcomes. Women with mild disease are considered as having ‘low‐risk endometriosis’ (LRE) and can expect a normal pregnancy and labour. The ‘high‐risk endometriosis’ (HRE) group may require additional antenatal and intrapartum specialist care. Learning objectives To understand the pathophysiologic basis of adverse obstetric and perinatal outcomes in pregnant women with endometriosis. To understand the obstetric outcomes in relation to the severity and staging of endometriosis. To appreciate the risk of spontaneous haemoperitoneum in pregnancy (SHiP) associated with endometriosis in pregnancy.
