In France, threatened preterm labour concerns 6.5% of pregnancies and is associated with a premature birth in 25.4% of cases. After 48 hours effective tocolysis, patients do not receive any further treatment while their risk of premature birth has risen from 6.5% to 25%. A pessary is a silicone ring encircling the cervix. It was initially used as medical treatment of genital prolapse but studies were also conducted for pregnant women in 2 high-risk premature birth situations: cervical incompetence and twin pregnancies. The multicenter PECEP trial conducted by Goya and al. in asymptomatic short cervix patients between 18 and 22 weeks of gestation showed a significant reduction of premature birth before 34 and 37 weeks of gestation. Thereby, the investigator assume that use of pessaries in patients presenting a resolutive threatened preterm labor will also be effective. To evaluate this hypothesis, the investigator designed a randomized prospective single-center open clinical trial comparing pessary associated with standard care (1st group) versus standard care only (2nd group) in patients experiencing an episode of resolutive threatened preterm labor.
