Modification of cervical length after cervical pessary insertion: correlation weeks of gestation.

Objectives: To observe the modifications in cervical length (CL) in patients with and without cervical pessary (Arabin® ASQ 65/25/32) and correlate these modifications with gestational age at delivery.

Study Design: Prospective study of asymptomatic singleton pregnancies (PECEP-Trial) between weeks 20 + 0 and 23 + 6 with maternal short cervix (<25 mm) randomised into two groups: expectant management and cervical pessary.

Results: This study included 380 pregnant women: 190 with pessary and 190 without pessary.

Cervical pessary in pregnant women with a short cervix (PECEP): an open-label randomised controlled trial.

Background: Most previous studies of the use of cervical pessaries were either retrospective or case controlled and their results showed that this intervention might be a preventive strategy for women at risk of preterm birth; no randomised controlled trials have been undertaken. We therefore undertook a randomised, controlled trial to investigate whether the insertion of a cervical pessary in women with a short cervix identified by use of routine transvaginal scanning at 20-23 weeks of gestation reduces the rate of early preterm delivery.

Methods: The Pesario Cervical para Evitar Prematuridad (PECEP) trial was undertaken in five hospitals in Spain.
