RESUMEN

<p><b>OBJECTIVE</b>To improve the understanding of recognizing and diagnosis of neonatal necrotizing enterocolitis (NEC), imaging assessment of neonates with NEC was analyzed retrospectively.</p><p><b>METHOD</b>Data of 211 cases of NEC were retrospectively collected from the Department of Neonatology, Children's Hospital of Chongqing Medical University between Jan.1(st) 2006-Dec.31(st) 2011.</p><p><b>RESULT</b>Analysis of abdominal X-ray of 211 cases showed that there were 40 cases (19.0%) who had no changes on each X-ray, 47 cases (22.3%) had improvement and 23 cases (10.9%) became worse. In the group of no changes, positive rate with good prognosis was 97.5% and with poor prognosis, it was 2.5%. In the group of improvement, positive rate with good prognosis was 97.9%, and the contrary was 2.1%. Positive rate with good prognosis was 56.5%, and the contrary was 43.5% in worse group. Chi-square analysis of the three groups showed χ(2) = 31.742, P < 0.01. Comparison of detection rate of pneumoperitoneum on abdominal X-ray (16.0%, 12/75) and Doppler US (1.3%, 1/75), χ(2) = 10.191, P < 0.05, portal pneumatosis on abdominal X-ray(1.3%, 1/75) versus Doppler US (12.0%,9/75), χ(2) = 6.857, P < 0.05. Surgical timing mostly corresponded to pneumoperitoneum (OR = 19.543) and intestinal obstruction (OR = 19.527) of abdominal X-ray. The logistic regression equation is y = -2.915-1.588x1+2.972x4+2.973x7 + 1.711x9 (χ(2) = 101.705, P < 0.01).</p><p><b>CONCLUSION</b>Abdominal X-ray is the most important method of diagnosis of NEC, the group of deterioration of abdominal X-ray has obvious bad prognosis differ from no change group and better group. Comparison with abdominal X-ray and Doppler US, the former in pneumoperitoneum positive rate was higher than the latter, at the same time, portal pneumatosis on Doppler US is more sensitive to abdominal X-ray, the value of two imaging assessments both supplement each other. Surgical timing mostly corresponds to pneumoperitoneum and intestinal obstruction.</p>
