Background

  • Abbreviation: NEC
  • Intestinal necrosis in previously well infant
  • Typically presents in 1st week of life, with case reports to 6 months in children that are chronically ill.
  • Predominantly affects preemies; 10-15% occurs in full-term patients
  • Bacterial overgrowth in bowel, translocation of bacteria into bowel wall, subsequent bacterial endotoxin and gas production

Clinical Features

Differential Diagnosis

Pediatric Abdominal Pain

0–3 Months Old

3 mo–3 y old
