[The value of an antiprogesterone steroid in the treatment of extra-uterine pregnancy. Preliminary results].

The aim of this work is to study the effects of an antiprogesterone drug (RU 486) on extrauterine pregnancy and to draw from it possible inferences for therapy. The study was carried out on 28 patients presenting an extrauterine pregnancy, the levels of plasma chorionic gonadotrophins of whom were higher than or equal to 250 mIU/ml. Different modes of administration were employed and a coelioscopic salpingotomy was carried out for a pathological study.
