Abstract
INTRODUCTION:
Our objective was to determine whether longer interval between dilation and evacuation and subsequent conception is associated with improved outcome of subsequent pregnancy.
METHODS:
We performed a retrospective cohort study of all women undergoing dilation and evacuation at our institution over a 12-month period to evaluate the outcome of their subsequent pregnancy. We included all patients who had at least one documented pregnancy after dilation and evacuation for which the final outcome was known. Primary outcome was incidence of live birth in a subsequent pregnancy in relation to interval time between pregnancies. Secondary outcomes were incidence of cervical insufficiency, small-for-gestational-age neonates, placental abnormalities, and primary cesarean delivery.
RESULTS:
There were 212 women who had a documented subsequent pregnancy after dilation and evacuation during the study period. The majority (83.5%) had a live birth, whereas 16.5% had another pregnancy loss. The women who had live births had significantly shorter average interval between dilation and evacuation and subsequent conception (225 compared with 350 days, P=.001) than the women who had another loss. When categorized into groups based on pregnancy interval length (less than 30 days, 30–60 days, etc), there was no significant difference in pregnancy outcome for any of the groups.
CONCLUSIONS:
Most women will achieve a live birth in their subsequent pregnancy after dilation and evacuation. A short interval between dilation and evacuation and conception is not associated with increased risk of pregnancy loss.
