腹腔镜下子宫峡部环扎术

子宫峡部环扎术是治疗宫颈机能不全最主要的方法。对于反复经阴道环扎失败或宫颈解剖异常不能经阴道环扎的患者，可选择经腹腔镜子宫峡部环扎。腹腔镜子宫峡部环扎术可在非孕期或早孕期进行。孕中晚期发生胎儿异常需终止妊娠时可经剖腹或腹腔镜拆除缝线经后阴道分娩。足月妊娠则需要剖宫产终止妊娠。腹腔镜下子宫峡部环扎术是治疗宫颈机能不全的有效方法之一，但其是否能作为治疗宫颈机能不全的标准术式尚待多中心临床随机对照研究结果证实。

Laparoscopic cervicoisthmic cerclage.

Abstract:Cervicoisthmic cerclage is the main procedure for cervical incompetence. Laparoscopic cervicoisthmic cerclage is an alternative and effective method for those who have the history of transvaginal approach or abnormal cervical anatomy. Laparoscopic cervicoisthmic cerclage can be carried out before pregnancy or during first trimester pregnancy.For women who have a fetal demise in the second trimester, vaginal delivery can still be achieved after cutting or removal of Mersilene tape through laparotomy or laparoscopy. Cesarean section should be performed for women with term pregnancy. Laparoscopic cervicoisthmic cerclage is one of the most effective procedures for the treatment of cervical incompetence. However, there is still lack of strong evidences from randomized clinical trials, especially from domestic research;to support that laparoscopic cervicoisthmic cerclage should be the standard procedure in the treatment of cervical incompetence.
