Pessary use for reduction of preterm birth (March 2016)

 The efficacy of using a vaginal pessary to improve pregnancy outcome in women with a short cervix is controversial. Recently, the largest randomized trial of pessary use in pregnant women with a short cervix (n = 932 participants) reported no differences between the pessary and control (no pessary) groups in rates of spontaneous delivery <34 weeks, perinatal death, adverse neonatal events, or need for neonatal special care [6]. We believe the body of evidence does not support pessary use for pregnant women with a short cervix. However, further study is warranted as the available evidence is limited by differences in use of progesterone prophylaxis and the low number of preterm births and neonatal complications in published trials.
