Abstract
Objective
To evaluate the efficacy and safety of prophylactic cervical cerclage by laparoscopy in pregnant women versus transvaginal way.
Design
Retrospective, monocentric cohort study was performed.
Setting
The First Affiliated Hospital of Sun Yat-sen University.
Patients
Cases with cervical insufficiency (defined by previous history of painless second or early third trimester pregnancy loss/losses) were selected.
Interventions
Laparoscopic or transvaginal cerclage were conducted. The maternal information and the neonatal data were collected and compared. The pregnancy outcomes including the incidence of full-term labor and gestational weeks at delivery were defined as the primary outcomes. Neonatal survival and birth weight, neonatal complications were evaluated as the secondary outcomes.
Measurements and main results
Totally 36 twin pregnant cases and 82 singleton pregnant cases were managed with cerclage, either trans-laparoscopy (totally 78 cases) or transvaginal (totally 40 cases). Demographic characteristics showed no significant differences. Cases in laparoscopic group had a prolonged gestational age at delivery (36.43 ± 0.93 weeks and 33.60 ± 2.78 weeks, respectively, P < 0.001), a higher incidence of full-term labor (60.26% vs 42.50%, P = 0.05) with no significant difference of perinatal mortality (P = 0.661). Meanwhile, higher incidence of normal birth weight infants (88.46% vs 67.50%, P = 0.007) was shown in laparoscopic group with no more complications such as the cases of neonatal with Apgar < 7 (P = 0.296), and the incidence of NICU admission (P = 0.237). Besides, LTC showed good efficiency on VTC in the incidence of full-term labor: HR 0.24 (95% CI 0.070–0.85), P < 0.001. While LSC showed the similar efficiency on VSC: HR 0.734 (95% CI 0.36–1.49), P = 0.857, showing that cases with twin pregnancy may benefit more from laparoscopic cerclage.
Conclusions
The comparative effect between laparoscopic and transvaginal cerclage in pregnant women showed that laparoscopic cerclage may be a relatively effective and safety prophylactic way for cervical insufficiency. This would be an acceptable and safe replace for traditional transvaginal cervical cerclage.
