Meta AnalysisInterventions to Try to Prevent Preterm Birth in Women With a History of Conization: A Systematic Review and Meta-analyses.
The most effective preterm birth (PTB) intervention is unknown for women who are at risk of PTB due to a history of conization. The objective of this systematic review was to determine whether PTB interventions, progesterone, cerclage, and pessary decrease the risk of PTB compared to no treatment in singleton-and separately in twin-pregnancies of women with history of conization. ⋯ In women with a previous conization and a current singleton gestation, the existing evidence, which is likely limited due to confounding by indication, does not support cerclage or other interventions used to try to decrease PTB.
