Perinatal Outcome in the Live-Born Infant with Prenatally Diagnosed Omphalocele

ABSTRACT

We compared perinatal outcomes between live-born nonisolated and isolated omphaloceles diagnosed during a prenatal ultrasound. Fetuses (n = 86) with omphalocele were identified between 1995 and 2007 at a single institution. Inclusion criteria were an omphalocele >14 weeks' gestation, available fetal and/or neonatal karyotype, and a live-born infant (n = 46). Perinatal outcomes were compared in nonisolated (n = 23) and isolated omphaloceles (n = 23). For all omphaloceles, the majority delivered after 34 weeks by cesarean. Mean birth weight (2782 versus 2704 g), median length of stay (27 versus 25 days), and mortality (two deaths in each group) were not different between the nonisolated and isolated groups (p > 0.05). In the nonisolated group, seven major anomalies were not confirmed postnatally. Of the prenatally diagnosed isolated omphaloceles, 8 (35%) were diagnosed with a syndrome or other anomalies after birth. The outcomes were similar in nonisolated and isolated prenatally diagnosed omphaloceles, but ultrasound did not always accurately determine the presence or absence of associated anomalies.
