Full text available on request.Abstract
Pregnancy after endometrial ablation is not recommended as it can lead to a potential life-threatening situation. Little information is available about the safety of an abortion procedure after an endometrial ablation and less is known whether the mode of abortion makes a difference. Aim of the study was to examine the complication rates of medical and surgical abortion procedures. Methods: A retrospective cohort study was performed using data collected in the database of Planned Parenthood of the Great Northwest and Hawaiian Islands between January 2017 and October 2020. Women with a history of endometrial ablation undergoing either a medical or surgical abortion were matched (1:2) with otherwise similar patient characteristics but without an endometrial ablation. Demographic, clinical and pharmaceutical variables were collected. Non-parametric tests were used to calculate relative risks to compare the outcomes between the cohorts. Results: A total of 20 women were identified having had an endometrial ablation and desire for ending the pregnancy. A total of 40 well matched controls based on gestational age, mode of abortion and history of cesarean delivery. There was no higher risk of complications in abortions after an endometrial ablation versus the unexposed group (RR=2.0, 95% CI 0.4-9.0). No difference in risk was found between both methods of abortion in patients with an endometrial ablation (RR=0.61, 95% CI 0.1-5.7). Remarkable was that prior to the index pregnancy 75% of the cases were not using any form of birth control. Conclusion: An abortion procedure in patients with a history of endometrial ablation is not associated with an increased risk of complications. The initial perceived risk of performing a medical abortion is not justified according to our research, so there is no indication avoiding this method.
