Abstract
PURPOSE: To study the feasibility, learning curve, and safety of fetoscopy, so that fetal surgery can be confidently performed in ongoing pregnancies. METHODS: Fetoscopy was performed at 12-20 weeks of gestation, in 12 women with fetal congenital malformations and/or for termination of pregnancy, under local anesthesia using fine fetoscopes ranging from 1 to 2-mm diameter. The fetal parts and placenta were examined for clarity of vision, identification, and anomalies. RESULTS: Fetoscopy required great skill, patience, and extensive use of ultrasound for correct orientation. Visualization was better with endoscope of 2-mm diameter. Laser coagulation of placental vessels using diode laser system was possible in the last two cases. There were no major complications. CONCLUSIONS: Fetal endoscopy is a feasible procedure, safe in experienced hands but has an appreciable learning curve.
