Comparison between vaginal and laparoscopic cerclage in women with mid-trimester pregnancy loss or history of spontaneous preterm delivery

Women with unfavorable obstetric history can benefit from prophylactic cerclage ("history indicated") which can be performed vaginally or transabdominally with laparoscopic techniques. The aim of our study is to evaluate the effectiveness in the prevention of preterm birth of the vaginal technique and of the minimally invasive laparoscopic technique in women with an unfavorable obstetric history.
