Necrotizing Enterocolitis in Term Neonates

Neerotizing enterocolitis (NEC) is usually a disease of premature infarits, but occasionally it affects the term neonate. Fifty-two patients with NEC were treated between 1965 and 1992. Eighteen fuli-term neonates with gestational age greater than 38 weeks were ideiatified for further study. Data were reviewed for recognized risk factors, clinical course, surgical intervention and outcome. The remlts reveled that NEC developed early in this group, with the onset of the disease in the first 48 hours of life in 50% and within the first 4 days of life in 90% approximately. The disease process affected the colonic region in all excoption 4 cases the small bowel was involved. The clinical experieace indicated that the presentation, clinical ourse, operative findings and prognosis in the term neonates with NEC differed from those encountered in the premature infants.
