The role of transabdominal cervical cerclage techniques in maternity care

Key content: The transabdominal cerclage procedure aims to strengthen the cervix by placing a suture at the level of the internal os. The main indications for transabdominal suture are a grossly disrupted cervix, an absent vaginal cervix, and previous failed elective vaginal cerclage. The transabdominal cerclage was first described in 1965 and the laparoscopic modification was first reported in 1998. Published reports suggest very high neonatal survival rates with both approaches. Laparoscopic cerclage has the general advantages of minimal access surgery, such as avoiding a large abdominal incision, short hospital stay and quick recovery. Potential complications include bleeding from uterine vessels and loss of pregnancy for non‐interval procedures. The other reported complications, such as suture migration, rectouterine fistula, uterine rupture and intrauterine growth restriction, are rare. The place of transabdominal cerclage in preventing pregnancy loss and preterm birth remains a subject of debate and there is a need to audit the outcomes. / Learning objectives: To better understand the role of the cervix in miscarriage. To understand the indications for referral for transabdominal cervical cerclage. To understand the obstetric and neonatal outcomes of women after this procedure. / Ethical issues: To consider the place of this invasive procedure, with its consequent possible complications, in the management of cervical weakness in women who often have poor reproductive histories. To consider the lack of national and international availability of this potentially valuable procedure. To consider an effective system of assessment of this procedure in a referral context, and the future of this procedure
