Effect of cervical pessary on pregnancy outcome in patients with twin
pregnancies: a systematic review and meta-analysis
Abstract
Conclusion The cervical pessary can extend the gestational week of
short-cervix twin pregnancy without clinical symptoms, reduce the
premature birth rate before 34 weeks of gestation, improve pregnancy
outcome, reduce neonatal mortality, reduce necrotizing enterocolitis
incidence, neonatal sepsis incidence, and improve neonatal outcome. For
patients with a cervical length less than 38mm, a cervical pessary can
be performed to extend the gestational week. For patients with a
cervical length less than 25mm, a cervical pessary can effectively
prolong the gestational age and improve the maternal and fetal outcomes.
The cervical pessary is safe for patients with twin pregnancies. Suggest
that twin-preganct-patients with CL<38mm should consider take
cervical pessary in advance. In terms of long-term efficacy, there is no
evidence of cervical support placement on the long-term maternal
prognosis. In terms of economic benefits, cervical support is better
than vaginal progesterone, but this conclusion still needs more research
to prov
