Abstract
Necrotizing enterocolitis (NEC) is the most serious and frequently acquired gastrointestinal disorder in neonates. The pathogenesis of NEC is unknown, but it may result from a disturbance of the delicate balance among gastrointestinal perfusion, enteric organisms, and enteral feeding. Risk factors for NEC include prematurity, hypoxic-ischemic insult, and formula or breast milk feedings. The clinical spectrum of NEC is multifactoral and ranges from temperature instability, apnea, lethargy, abdominal distention, bilious residuals, and guaiac-positive stools to septic shock, disseminated intravascular coagulation, and death. Medical management is usually adequate treatment for NEC. Surgical treatment is considered if medical management is inadequate to control the spread of the disease. Health care team members must be constantly alert to the presentation of NEC. Expeditious treatment will positively influence the outcome of the disease.
