In Utero Fetoscopic Repair Program for Sacral Myelomeningoceles and Mye-LDM

After an exteriorization of the uterus through a laparotomy, humidified and warmed gas will be insufflated with low pressure (6 to 8mmHg mmHg). Fetoscopic repair surgery will consist in a dissection of the placode, its reintegration into the spinal canal and the closure of the lesion, through a three ports access. After fetal surgery, the gas will be exsufflated and the trocar ports will be closed. The uterus will be reintegrated before suturing the maternal abdominal wall.
