Attempted endoscopic fetal interventions have been increasingly reported, given the knowledge that minimizing the trauma to the uterus by a small access portal can allow prolonged amnioscopic-guided surgery. Numerous fetal anomalies have been targeted for these interventions, including congential obstructive uropathies. This preliminary investigation explored innovative access strategies utilizing time-dated pregnant ewes, 95 to 100 days' gestation (term 145 days). Two strategies were specifically investigated: percutaneous, ultrasonographically guided microamnisocopy and ultrasonographically aided, laparoscopically guided amnioscopy. Both strategies provided excellent fetal visibility and were facilitated by the use of small trocars and microlaparoscopic instrumentation, which promoted prolonged amnioscopy with minimal access trauma.
鉴于通过小入口通道将子宫创伤降至最低可使羊膜镜引导手术得以延长，越来越多的人报道了尝试进行内镜下胎儿干预。这些干预针对的胎儿异常情况众多，包括先天性梗阻性尿路疾病。这项初步研究利用妊娠95至100天（足月为145天）的定时怀孕母羊探索了创新的进入策略。具体研究了两种策略：经皮超声引导下微羊膜镜检查和超声辅助腹腔镜引导下羊膜镜检查。两种策略都能提供极佳的胎儿视野，并且使用小型套管针和微型腹腔镜器械有助于实现这一点，这些器械促进了长时间的羊膜镜检查，同时使进入创伤最小化。
