Preterm birth is a leading cause of neonatal mortality and morbidity. Cervical insufficiency is one factor implicated in the complex mechanisms involved in spontaneous preterm birth. Trans-abdominal insertion of a cervical cerclage suture can be used to treat cervical insufficiency. Growing evidence support that laparoscopic cerclage procedures are safe and effective. Still, many aspects of the laparoscopic cerclage remains uncertain. Therefore, the investigators plan to study the obstetric outcome from the first and subsequent pregnancies after laparoscopic cerclage in a Danish cohort from Aarhus University Hospital in a 10 years' period.
