Insights
Very preterm infants (VPIs) surgically treated for necrotizing enterocolitis (NEC) show poor growth, particularly in head circumference. Growth improved after stoma closure, highlighting the impact of surgical NEC treatment on VPI development.
Area of Science:
- Neonatal surgery
- Pediatric growth and development
- Gastrointestinal disorders
Background:
- Infants born very preterm (VPIs) undergoing surgery for necrotizing enterocolitis (NEC) face risks of impaired growth.
- Understanding long-term growth trajectories is crucial for managing these vulnerable infants.
Purpose of the Study:
- To compare the growth of VPIs with a stoma after NEC surgery to VPIs without NEC surgery up to 6 years of age.
- To identify specific growth patterns and potential recovery after surgical intervention for NEC.
Main Methods:
- Retrospective cohort study of VPIs surgically treated for NEC between 2004-2008.
- Growth data collected from medical records and parental reports.
- Comparison group of VPIs without NEC surgery.
Main Results:
- Nineteen VPIs with NEC and stoma survived to 6 years.
- VPIs with NEC and stoma exhibited poorer growth compared to controls, notably in head circumference (HC).
- HC growth velocity showed no improvement until after stoma closure (2.5-3 months corrected age).
Conclusions:
- Surgical NEC treatment in VPIs is associated with significant growth deficits.
- Stoma closure appears to positively influence head circumference growth in these infants.
Introduction:
Very preterm infants (VPIs) surgically treated for necrotizing enterocolitis (NEC) are at risk of growth retardation. The aim of this study was to demonstrate and compare growth during the first 6 years of life in VPIs with stoma after NEC surgery with VPIs without NEC surgery.
Materials And Methods:
We included all VPIs surgically treated due to NEC at the Odense University Hospital from August 1, 2004, to July 31, 2008. Outcome on growth was compared with a group of VPIs without NEC. The VPIs with NEC were identified searching the local database using the International Classification of Diseases, 10th Revision diagnosis of NEC (DP77.9). Data on growth were collected from medical files and if not present, the parents reported the data.
Results:
Nineteen VPIs, surgically treated due to NEC, survived to 6 years of age. Median gestational age was 283/7 weeks (245/7-313/7). Median age at NEC surgery and stoma formation was 2.3 weeks (0.1-6.3) and median age at stoma closure was 2.5 months corrected age (CA) (postmenstrual age 36 weeks to CA 6.7 months). Compared with the non-NEC group, VPIs with NEC and stoma demonstrated poor growth, especially in head circumference (HC) with no increase in growth velocity before the time of stoma closure between 2.5- and 3-month CAs.
Conclusion:
Our findings demonstrate poor growth in VPIs after NEC surgery and improved HC growth after stoma closure.
