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.
宫颈机能不全是导致妊娠中期流产和自发性早产的主要原因。对于宫颈机能不全的患者,通常在怀孕前进行经腹宫颈峡部环扎术,但对于那些之前未进行经阴道宫颈环扎术或经阴道宫颈环扎术失败的患者,进行经腹环扎术则极具挑战性。由于怀孕子宫增大,对于那些原本需要进行经腹宫颈峡部环扎术但在怀孕前未进行该手术的患者来说,进行经腹环扎术变得极具挑战性。在这里,我们概述了一种在妊娠中期早期进行的简单有效的手术方法,即无针腹腔镜经阔韧带宫颈峡部环扎术。在扩张输尿管三角、卵巢血管和子宫动脉升支后,建立腹腔镜 4 个trocar。将无针 Mersilene 带从前向后插入双侧输尿管三角,将结向膀胱子宫反射方向收紧,并同时将环向后推至子宫后面,逐渐向宫颈方向推进。在经阴道超声确定第一结存在子宫动脉收缩速度后,在宫颈峡部交界处用 5 到 6 个体内方结在前方进行结扎。我们手术的主要特点是无针 Mersilene 带从中宽韧带中央插入,位于子宫血管旁,最后在子宫骶骨韧带上方打结,位于子宫峡部水平,无需将膀胱从下段子宫分离,也无需将子宫血管与宫颈侧壁分离。我们对 10 例妊娠结局患者进行了该手术,无一例妊娠丢失。该手术证明是一种可行且有效的妊娠中期早期经腹宫颈环扎术,预后肯定。
