    Necrotizing enterocolitis (NEC) affects primarily low-birth-weight infants, often within the first week of life. Complications like pneumoperitoneum and intestinal obstruction increase mortality risk.

    Area of Science:

    • Neonatal Medicine
    • Pediatric Surgery
    • Gastroenterology

    Background:

    • Necrotizing enterocolitis (NEC) is a significant cause of morbidity and mortality in neonates.
    • It predominantly affects premature and low-birth-weight infants.
    • Early diagnosis and management are crucial for improving outcomes.

    Purpose of the Study:

    • To analyze the incidence, clinical features, complications, and outcomes of necrotizing enterocolitis in a neonatal intensive care unit.
    • To identify risk factors and patterns associated with NEC development and progression.
    • To evaluate the impact of complications on overall mortality.

    Main Methods:

    • Retrospective review of 40 infants diagnosed with NEC over a 33-month period.
    • Diagnosis confirmed pathologically (surgery/autopsy) or clinically/radiologically (intramural gas).

  • Data collected on birth weight, gestational age, clinical presentation, complications, and mortality.

    • Main Results:

    • NEC represented 4% of neonatal admissions; primarily affected low-birth-weight infants.
    • Two-thirds of cases developed within the first week of life.
    • Common complications included pneumoperitoneum (34%), localized peritonitis (11%), and intestinal obstruction (25%), with increased mortality (38%) in perforation/obstruction cases.

    Conclusions:

    • NEC is a serious condition in neonates, particularly those with low birth weight.
    • Prompt recognition of clinical and radiological signs is essential for timely intervention.
    • Complications significantly impact prognosis, highlighting the need for vigilant monitoring and management strategies.
