necrotizing enterocolitis
Serious gastrointestinal condition primarily affecting premature infants, characterized by intestinal inflammation and necrosis visible on imaging.
Full Definition
A severe inflammatory condition of the intestine that predominantly affects premature neonates, characterized by intestinal wall inflammation, necrosis, and potential perforation. Radiographic signs include pneumatosis intestinalis (gas within the bowel wall), portal venous gas, and pneumoperitoneum if perforation occurs. Early radiographic changes may be subtle, requiring serial imaging for progression assessment. The condition can rapidly progress from mild intestinal distension to life-threatening complications requiring surgical intervention. Close collaboration between radiology, neonatology, and pediatric surgery is essential for optimal management. Ultrasound may complement radiography in evaluating bowel wall integrity and detecting early complications.
