Can omphalocele ratio predict postnatal outcomes?

Area of Science:

• Neonatal surgery
• Pediatric surgery
• Congenital anomalies

Background:

• Predicting clinical outcomes for neonates with omphalocele is difficult.
• No standardized method exists to quantify omphalocele size.
• Prenatal omphalocele measurements may correlate with postnatal outcomes.

Purpose of the Study:

• To investigate the correlation between the omphalocele ratio (OD/AC) and postnatal outcomes.
• To determine if the omphalocele ratio can predict the need for primary versus staged closure.

Main Methods:

• Retrospective review of 30 neonates with omphalocele and prenatal ultrasounds (2002-2013).
• Omphalocele ratio calculated as omphalocele diameter/abdominal circumference (OD/AC).
• Collected data included closure type, ventilation duration, feeding time, and length of stay.

Main Results:

• An optimal OD/AC ratio cutoff of 0.26 was identified.
• Patients with a ratio < 0.26 had significantly higher rates of primary closure (60% vs. 0%).
• Low-ratio group showed shorter mechanical ventilation duration (15.8 vs. 79 days) and length of stay (33.8 vs. 85.6 days).

Conclusions:

• The omphalocele ratio is a valuable and promising predictor of postnatal outcomes in neonates with omphalocele.
• This ratio can aid in surgical planning and outcome prediction.
