Abstract
Patients with gastroschisis and prolonged total (or partial) parenteral nutrition (PN) commonly develop direct hyperbilirubinemia (DH). To quantify the prevalence and severity of DH in newborns with gastroschisis and characterize the diagnostic work-up for DH in this patient population. Retrospective chart review of patients born with gastroschisis between 2005 and 2015 for the first 6 months of life. 29 patients were identified with gastroschisis. Mean gestational age and birthweight were 36.4 (± 1.8) weeks and 2.5 (± 0.6) kg. 41% were treated with primary reduction versus staged closure. Peak total and direct bilirubin (DB) levels were 10.17 ± 6.21mg/dL and 5.58 ± 3.94mg/dL, respectively. 23 patients (79.3%) were diagnosed with DH and 78.2% underwent additional work-up for hyperbilirubinemia consisting of imaging and laboratory studies, none of which revealed a cause for DH other than the presumed PN-associated cholestasis. In all patients, DB began to decline within 1-10 days of initiation of enteral feeds. DH is common in patients with gastroschisis and is unlikely to be associated with pathology aside from PN. Additional work-up may lead to unnecessary resource utilization. Case series with no comparison group, Level IV.
