Laparoscopic abdominal cerclage during pregnancy: a simplified approach

Cervical insufficiency is a major cause of second-trimester pregnancy loss and spontaneous preterm delivery. Transabdominal cervicoisthmic cerclage is usually performed before pregnancy for patients of cervical insufficiency, in whom transvaginal cervical cerclage procedure cannot be placed or has failed previously. Performing a transabdominal cerclage becomes a huge challenge owing to the enlargement of the pregnant uterus in patients who were indicated for transabdominal cervicoisthmic cerclage but were missed before pregnancy. Here, we have outlined an easy and effective surgical procedure as needle-free laparoscopic trans–broad-ligament cervicoisthmic cerclage during early second-trimester. Laparoscope with 4 trocars was established, after expanding the trigonum of ureter, ovarian vascular and ascending branch of uterine artery. The needleless Mersilene tape was inserted in a posterior-to-anterior direction of bilateral trigonums, tightening the knot toward the bladder uterine reflection and simultaneously pushing the loop behind the uterus, directed to the cervix progressively. The tape was then tied anteriorly at the cervico-isthmic junction with 5 to 6 intracorporeal square knots after transvaginal ultrasound determined the presence of systolic velocity of uterine artery with first knot. The primary feature of our procedure was that the needleless Mersilene tape was inserted centrally from the broad ligaments, lateral to the uterine vessels, and finally tied above the uterosacral ligament at the level of the uterine isthmus, without dissecting the bladder off from lower uterine segment and without separating the uterine vessels from the lateral wall of the cervix. We performed this procedure on 10 patients with pregnancy outcomes and there was no pregnancy loss. This procedure proved to be an accessible and effective surgical technique for transabdominal cerclage of the uterine cervix during early-second trimester, with affirmative prognosis.
