Brief Answer: Pediatric surgeon and obsterician collaboration Detailed Answer: Hi and thanks for the query, One of the main important factors to be considered in this case shall be the gestational age at which the baby shall be born (premature or at term) and also the mode of delivery (surgical or normal vaginal delivery). These parameters are important in order to take appropriate precautions with respect to the risk of infections and timing of the surgery. In case the baby is at term, appropriate surgical measures could be taken immediately after delivery to undertake the surgery. Depending on whether the child would have respiratory distress or not, or if the child has other malformations or not, the rapidity of the surgery shall take these parameters into consideration. In case the baby is not at term, some time might be required for the child to mature to a particular extent to be able to support surgery. A fine pediatric surgeon shall be required with a very diverse specialized team. Successes are recorded, but this usually depends on the timing of surgery, gestational age, presence of other malformations, presence of a concomitant infection, and expertize and experience of the operating team Outcomes in children with other malformations, who are born before term and vaginally with more infections are generally poorer than in patients at term with less associated complications. A complete evaluation and agreement between the pediatric surgeon and the obstetrician is very important. Kind regards as I wish you the best. Dr Bain
