Latency to delivery in physical examination‐indicated cerclage in twins is similar to that in singleton pregnancies.

Objective: To compare latency to delivery and perinatal outcomes between twin and singleton pregnancies undergoing physical examination‐indicated cerclage. Methods: Retrospective observational study (2007–2017) of women who underwent physical examination‐indicated cerclage at the Hospital Clinic of Barcelona. Primary outcomes were latency from cerclage to delivery and gestational age at delivery. Secondary outcomes included: neonatal morbidity and mortality, preterm prelabor rupture of membranes, clinical chorioamnionitis and cerclage displacement. Wilcoxon‐test and χ2 test were used to compare continuous and categorical variables. Results: Sixty women were included (17 twins and 43 singletons). There were no differences in gestational age at cerclage or presence of bulging membranes between groups. Median (25th;75th percentile) gestational age at delivery was 27.1 (24.5;32.3) weeks in the twin group and 27.6 (25.3;35.3) weeks in the singleton group (P = 0.594). There were no statistically significant differences in latency from cervical cerclage to delivery between the two groups (43 days [21;64] vs. 29 days [16;76], respectively; P = 0.938). There were no differences in neonatal mortality (2/26 [7.7%] vs. 1/33 [3.1%]; P = 0.578) or in composite neonatal morbidity (14 [53.9%] vs. 14 [42.4%]; P = 0.283) between groups, respectively. Conclusion: These results suggest that physical examination‐indicated cerclage placement in twins could prolong latency to delivery similarly to singleton pregnancies.

Physical examination‐indicated cerclage placement in twin pregnancy prolongs gestational age and latency to delivery similarly to singleton pregnancies. [ABSTRACT FROM AUTHOR]
