Associated Anomalies and Clinical Outcomes in Infants with Omphalocele: A Single-centre 10-year Review

YY Chee, MSC Wong, RMS Wong, KY Wong, KKY Wong, CT Lau


Objective: To examine the perinatal characteristics, associated anomalies and clinical outcomes of newborns with omphalocele admitted to Queen Mary Hospital (QMH), Hong Kong during a 10-year period. Methods: We identified all newborns with omphalocele who were admitted to the neonatal intensive care unit at QMH from 2005 to 2014. Maternal and patient demographic data, associated anomalies and outcome data were reviewed retrospectively. Results: A total of 19 infants with omphalocele were identified. Median gestational age at birth was 38 weeks with a median birth weight of 3140 g. Fifty-three percent (10/19) were diagnosed with at least 1 other anomaly, with congenital heart defect being the most common associated anomaly. Median age at first operation (either primary closure or application of silo) was on day 1 of life, with delayed closure in staged operations being carried out at a median age of 8 days. Infants with non-liver containing omphaloceles were more likely to have primary repair compared to those with liver-containing ones (7/8 [88%] vs. 4/11 [36%], p=0.03). Overall survival rate at discharge was 84% (16/19). Two out of 3 cases died of lethal congenital anomaly (alveolar capillary dysplasia) while the other one suffered from postoperative midgut volvulus. Postoperative complications occurred in 6 patients (6/17 [35%]), with ventral hernia being the most common complication. Long-term medical problems including failure to thrive (6/12 [50%]), gastroesophageal reflux (5/12 [42%]), developmental delay (3/12 [25%]) and recurrent lung infections (1/12 [8%]) were identified. Conclusions: Associated anatomic and genetic anomalies are common in omphalocele. Postnatal workup should include screening of these anomalies. Prognoses for isolated omphaloceles with no major postoperative complications are good in the long-term.
