While the actual neurosurgical repair proposed in this protocol will be different (simpler and of shorter duration) to that done in Barcelona and Mexico by Dr. Peiro, the exteriorization of the uterus and preparation for the fetoscopic repair surgery will be the same. In this protocol, the repair of the open neural tube defect will follow the same principles as we are already using in open repairs currently being done at this institution. This involves release of the placode, dissection of the surrounding skin and attempted primary closure of the defect using available skin. In those cases where we are able to complete the procedure with full skin closure of the defect, the only difference between the open uterus procedure and the fetoscopic procedure, will be that the surgery will be done fetoscopically rather than through an open uterine incision. If we are unable to close the skin primarily despite best fetoscopic efforts, the option of performing/completing the repair as an open procedure exists and will be offered to the patient. The patient is monitored in hospital until ready for discharge.
