Neonatal outcome of gastroschisis and exomphalos: a 10-year review.
OBJECTIVE
To study neonatal outcomes associated with gastroschisis and exomphalos in a regional neonatal unit.


METHODS
A retrospective (1988-97) data analysis to study the effect of the type of defect/surgery, mode/place of delivery and associated anomalies on time to start and reach full feeds, duration of total parental nutrition (TPN) support and total hospital stay. Exact bivariate test procedures were used for data analysis.


RESULTS
Twenty-one cases of gastroschisis (17 inborn) and five cases (four inborn) of exomphalos were identified. Of these, 23.8% cases of gastroschisis and 60% of cases of exomphalos had associated gut anomalies. The survival rates for gastroschisis and exomphalos were 91 and 100%, respectively. The median time to start and reach full enteral feeds in outborn neonates was longer than in inborn neonates (9 vs 25 days, respectively, P = 0.01; and 16 vs 49 days, respectively, P = 0.01), as was the duration of TPN support (14 vs 42 days, respectively; P = 0.02). Neonates with gastroschisis had significant delays in starting and reaching full feeds compared with neonates with exomphalos (median 13 vs 4.5 days, respectively, P = 0.03; and 24 vs 8, respectively, P = 0.02) and they required prolonged support with TPN (median 23 vs 6 days, respectively; P= 0.01). Antenatal detection was significantly more frequent in inborn compared with outborn neonates (100 vs 67%, respectively; P = 0.03). The severity of associated gut anomalies and the delivery to surgery interval did not differ significantly to explain the increased morbidity in outborn neonates. Outcome was not significantly different after analysis by type of surgery and mode of delivery.


CONCLUSIONS
Increased morbidity in outborn neonates may be related to factors such as temperature, care, hydration status, care of the defect and vascular compromise of prolapsed gut during prolonged transportation.
