Abortion medical management between 14-16 weeks' amenorrhea after French legislation deadline extension.

BACKGROUND

The National French Assembly promoted a law in 2022 allowing an extension of the period of abortion up to 16 week's amenorrhea. Medication protocols vary internationally, and there are no French data on medical management between 14- and 16-weeks' amenorrhea.

OBJECTIVE

To assess effectiveness and feasibility of a medical management abortion between 14 and 16 weeks of amenorrhea.

STUDY

DESIGN

We retrospectively collected data from women undergoing medical abortion between 14 and 16 weeks' amenorrhea from April 2022 to April 2023 in Archet's University hospital, Nice, France. Medical protocol consisted in a single dose of oral mifepristone 600 mg and 36-48 h later, vaginal gemeprost 1 mg. Three hours after gemeprost, oral 400 µg of misoprostol were administered every three hours, to a maximum of three doses. Success was defined as fetal expulsion.

RESULTS

Thirty women were enrolled in the study. Twenty-nine (96.7 %) patients aborted successfully. The median dose of misoprostol required was 800 µg (400 µg -1200 µg) and the median induction-to-abortion interval after first prostaglandin administration was 7 h (5.5-11.6). One patient (3.3 %) didn't expulse the fetus after 3 doses of misoprostol. Nine patients (30.0 %) had additional surgical aspiration for retained product of conception within 24 h. We encountered one post-abortum hemorrhage controlled only with surgical intra uterine aspiration. We did not need complementary hemostatic procedure and we reported no immediate or late complication.

CONCLUSIONS

Medical abortion between 14 and 16 weeks of amenorrhea provides a noninvasive and effective management for a daycare mid trimester abortion in 96.7 % of cases, with a 36.7 % of risk of staying in hospital overnight and 30.0 % to have additional surgery for retained product of conception (RPOC).
