X-ray is shown Intestinal wall gas and/or portal vein pneumatosis and pneumoperitoneum.~Two and more grades of NEC in newborn infant is a urgent condition, and whether or not operation is difficult to predict.~Here, the investigators develop a score system including five parameters(abdominal circumference, base excess, heart rate, severities of respiratory distress, sepsis) in one retrospective cohort, and the score system is used and assessed to predict the need for surgery in another prospective cohort.
