Second-trimester Termination of Pregnancy: A Retrospective Study Comparing Complications Related to Termination of Pregnancy at 12-14 Weeks' Gestation Versus 14-16 Weeks' Gestation

In France, the recently adopted law relating to the legal time limit for access to voluntary interruption of pregnancy has set a threshold of the term at which it can be performed up to 16 weeks of gestation. This single-centre study conduced at the Nancy Maternity Hospital is based on a retrospective cohort of all patients who underwent a medical termination of pregnancy between January 2010 and October 2021. The main objective is to evaluate the complications according to the term of the termination of pregnancy between two groups : [12-14] vs [14-16] weeks of gestation. The secondary objective is the distribution of these complications between the two groups. Pregnancy termination can be performed in two methods, either by medical method with mifepristone and misoprostol, or by surgical method by dilation and evacuation. Complications identified are haemorrhage, infection, retained product of trophoblast, uterine rupture and abortion induction failure. The hypothesis is the concomitant increase in complications with the term of the termination of pregnancy.
