NEC
Also written as: NEC — Necrotizing Enterocolitis
Necrotizing enterocolitis - a serious intestinal emergency in premature infants characterized by bowel wall necrosis and potential perforation.
Full Definition
Necrotizing enterocolitis (NEC) is a devastating gastrointestinal emergency predominantly affecting premature infants, characterized by inflammation and necrosis of the bowel wall. Radiological features progress from early signs of ileus and bowel wall thickening to pathognomonic pneumatosis intestinalis (air within the bowel wall) and portal venous gas. The most severe complication is intestinal perforation, which may present as pneumoperitoneum or loculated air collections. Serial abdominal radiographs are essential for monitoring disease progression and detecting complications. The condition carries significant morbidity and mortality, requiring immediate medical and often surgical intervention.
