A perinatal approach to the diagnosis and management of gastrointestinal malformations.

Ultrasonography now offers the opportunity to evaluate selected high-risk pregnancies for the presence of fetal malformations that are amenable to corrective measures as well as of those that remain incompatible with life. The authors observed major fetal malformations in 1% of 6050 cases that underwent antenatal ultrasonographic evaluation. A series of 9 prenatally diagnosed gastrointestinal tract anomalies, including the first documented instances of esophageal atresia diagnosed in utero, is presented in detail. Abdominal wall defects were those most commonly encountered in this series and were diagnosed as early as 16 weeks' gestation. The gastrointestinal system is not only one of the most common sites of birth defects, but it is also the one wherein lies the greatest hope for a successful neonatal outcome. The value of prenatal diagnosis in a comprehensive perinatal approach to congenital gastrointestinal lesions is emphasized. Forewarning the obstetrician and altering the pediatric-surgical team for resuscitation, immediate postnatal evaluation, and timely intervention decrease neonatal mortality and increase the chance of long-term infant survival.
