Abstract
OBJECTIVES
To estimate factors affecting survival in prenatally diagnosed omphalocele, factors predicting genetic abnormalities, and association of omphalocele and specific groups of anomalies.
METHODS
A retrospective observational study was performed, analyzing data of all omphalocele cases diagnosed prenatally in the perinatology clinic of a referral center. Demographic data, characteristics of the omphalocele (size, content, associated anomalies), results of genetic testing, pregnancy outcomes and postnatal outcomes were analyzed.
RESULTS
Sixty-nine fetuses with omphalocele were included. The prevalence of omphalocele in livebirth was 0.007 %. Overall survival during the study period was 73.9 %. Twenty-eight (71.7 %) out of 39 cases with associated anomalies who were born live, survived, whereas survival was 85.7 % in the isolated cases. The most common anomaly associated with omphalocele were cardiac defects with 42 %; followed by placental or umbilical cord anomalies (28.9 %), skeletal defects (27.5), genitourinary anomalies (20.2 %), central nervous system (18.8 %) and facial anomalies (7.2 %), respectively. Eighty-five percent of the fetuses had at least one additional anomaly or ultrasound finding. Skeletal abnormalities and staged surgical repair of omphalocele were associated with survival. Associated skeletal anomalies and staged repair significantly increase the risk of postnatal death (OR: 4.6 95 % CI (1.1-19.5) and (OR: 10.3 95 % CI (1.6-63.9), respectively).
CONCLUSIONS
Associated skeletal abnormalities and staged surgical repair are negatively associated with postnatal survival.
