Preterm birth is the leading cause of neonatal mortality and morbidity. Multiple interventions have been put in place to minimize this occurrence. Despite current recommendations including medical management, cervical length screening, and transvaginal cerclage a substantial number of women still experience preterm birth. For those patients, experts recommend a transabdominal cerclage. In our systematic review, we compare 26 studies (1116 patients) on transabdominal cerclage placed via laparotomy (TAC-lap) to 15 studies (728 patients) on transabdominal cerclage placed via laparoscopy (TAC-lsc)...

Preterm birth is the leading cause of perinatal morbidity and mortality in developed nations. The heterogeneous causes of spontaneous preterm birth make prediction and prevention difficult. The primary importance of transvaginal cervical sonography and cervicovaginal fetal fibronectin lies in their high negative predictive values in assessing risk for preterm birth. Cervical length may be useful in identifying women who are candidates for cervical cerclage or progesterone therapy for preterm birth prevention...
