Insights
Infants with gastroschisis had longer hospital stays and more infections than those with omphalocele. However, omphalocele infants experienced higher mortality rates, while gastroschisis mortality increased over time.
Area of Science:
- Neonatalogy
- Pediatric Surgery
- Public Health
Background:
- Abdominal wall defects (AWD) in infants, including gastroschisis and omphalocele, are associated with significant risks.
- These risks include prolonged hospitalization, infections, and mortality, impacting infant outcomes.
Purpose of the Study:
- To describe and compare the clinical outcomes of infants with gastroschisis versus omphalocele.
- To analyze trends in outcomes for these congenital anomalies over an 18-year period.
Main Methods:
- A population-based study utilizing clinical data from live-born infants with AWD.
- Data collected from all tertiary-level neonatal intensive care units in New South Wales and Australian Capital Territory.
- Study period spanned from 1992 to 2009, encompassing 502 infants with AWD.
Main Results:
- Infants with gastroschisis (n=336) required longer total parenteral nutrition (19 vs. 4 days) and hospitalization (28 vs. 15 days) compared to omphalocele (n=166).
- Gastroschisis cases showed higher systemic infection rates (23.5% vs. 13.3%).
- Omphalocele infants had a higher overall mortality rate (OR 2.77), while gastroschisis mortality increased from 4.2% to 8.8% over the study period.
Conclusions:
- Gastroschisis is associated with prolonged hospitalization, parenteral nutrition, and increased infection risk compared to omphalocele.
- Omphalocele presents a higher overall mortality risk, despite gastroschisis mortality rates rising.
- The increasing trend in gastroschisis mortality warrants further investigation.
Background/Purpose:
Infants with abdominal wall defects (AWD) are at risk of poor outcomes including prolonged hospitalization, infections and mortality. Our objective was to describe and compare the outcomes of infants admitted with gastroschisis and omphalocele over 18years.
Methods:
Population-based study of clinical data and outcomes of live-born infants with AWD admitted to all tertiary-level neonatal intensive care units in New South Wales and Australian Capital Territory from 1992 to 2009.
Result:
There were 502 infants with AWD - 336 gastroschisis, 166 omphalocele. Infants with gastroschisis required a longer duration of total parenteral nutrition (19 vs 4days, p<0.05), longer hospitalization (28 vs 15days, p<0.05) and had a higher rate of systemic infection [23.5% vs 13.3%, OR 1.77 (1.15-2.74), p<0.05] compared to infants with omphalocele. Overall, omphalocele infants had higher mortality rate compared to gastroschisis infants [OR 2.77 (1.53, 5.04), p<0.05]. Gastroschisis mortality rates increased from epoch 1 to epoch 3 (4.2% to 8.8%).
Conclusion:
Compared to infants with omphalocele, infants with gastroschisis required significantly longer hospitalization and parenteral nutrition with higher rates of infection. Infants with omphalocele had higher overall mortality rates. However, there has been an increase in the gastroschisis mortality rates but the cause for this is unclear.
