Neonatal necrotizing enterocolitis. A 10 year experience.

Area of Science:

• Neonatology
• Pediatric Surgery
• Gastroenterology

Background:

• Neonatal necrotizing enterocolitis (NEC) is a serious gastrointestinal emergency in neonates.
• The incidence of NEC varies significantly across neonatal intensive care units (NICUs).
• Risk factors for NEC include prematurity, low birth weight, and enteral feeding practices.

Purpose of the Study:

• To report the incidence of NEC in a specific NICU population.
• To identify clinical characteristics and outcomes of infants with NEC.
• To explore potential factors contributing to a lower-than-expected NEC incidence.

Main Methods:

• Retrospective review of infants admitted to NICUs.
• Analysis of NEC incidence, timing of onset, feeding practices, surgical interventions, and mortality.
• Comparison of observed NEC incidence with previously reported data.

Main Results:

• An incidence of 0.83% for NEC was observed in 5,030 NICU admissions.
• Most NEC cases developed after one week of life, particularly in very low birth weight infants.
• Delayed enteral feeding and reliance on parenteral nutrition were associated with lower NEC rates.

Conclusions:

• The observed low NEC incidence may be linked to delayed enteral feeding and increased use of parenteral nutrition.
• Early surgical intervention is crucial for NEC management, with high mortality rates.
• Further research is needed to confirm the protective effect of feeding strategies on NEC development.
