NCT02390895

Brief Summary

The purpose of this study is to determine the feasibility of prenatal minimally-invasive fetoscopic closure with i) uterine exteriorization for a minimally-invasive repair under amniotic carbon dioxide insufflation ii) two trocars for the dissection and the cover with one patch or the suture of the skin edges by stitch
