Introduction: congenital diaphragmatic hernia results from the incomplete fusion of the pleuroperitoneal membrane and occurs with a frequency of about ½.000-5.000 live-births. Despite advances in neonatal intensive care and surgery, mortality varies from one institution to another and may be above 75%. There are some prenatal prognostic factors that assess the CDH severity and thus, the fetal viability. Fetal tracheal occlusion (TO) in experimental animal CDH models, and in human fetuses induce lung growth. Fetal TO offers a better outcome for patients with severe CDH that otherwise would have a 100% mortality rate despite the advanced postnatal care. A greater number of cases are needed to obtain stronger conclusions. The major enemies of fetal surgery are the premature rupture of membranes and the preterm labor. Fetoscopic approach and tocolysis could help preventing these eventualities. Case study: we present the cases of two newborn babies with left- sided diaphragmatic hernia that allowed the passage of most of the abdominal viscerae into the thorax with only mild symptoms of respiratory failure. Keywords: diaphragmatic hernia, fetal surgery, intrauterine treatment, fetoscopy, tracheal occlusion.
