Minimally Invasive Transabdominal Cerclage: A Systematic Review of Laparoscopic and Robotic Assisted Techniques and Pregnancy Outcomes
摘要
Transabdominal cerclage is highly successful at improving neonatal survival and gestational age at delivery [3]. It can be performed prior to conception or during pregnancy in the second trimester, after genetic screening is complete and prior to significant enlargement of the uterus (12–15 weeks gestation). The purpose of this review is to provide the most recent summary of outcomes for laparoscopic transabdominal cerclage (LTAC) and robotic-assisted laparoscopic transabdominal cerclage (RA-TAC). Additionally, the review discusses the data for RA-TAC.
Recent FindingsThe average gestational age at delivery was slightly higher with LTAC compared with RA-TAC, however there was not a statistically significant difference given the low number of studies using RA-TAC. Both approaches achieved similar rates of delivery after 34 weeks gestational age and term deliveries.
SummaryBased on the existing published literature and our clinical experience, both LTAC and RA-TAC are highly effective at reducing the risk of preterm birth and improving neonatal survival. However, further research is needed to better understand the causes and contributing factors of cervical insufficiency. Additionally, further studies are needed to help determine which patients might benefit from a laparoscopic transabdominal cerclage instead of transvaginal cerclage as their first line management.
