Value Of Radiographic Duke Abdominal Assessment Scale Assist In Neonatal Necrotizing Enterocolitis

Objective To testify whether radiographic Duke AbdominalAssessment Scale assists in diagnosis and prognosis of neonatal necrotizingenterocolits (NEC).Methods Total222neonates of suspected or confirmed NEC,hospitalized during2012, were enrolled. The clinical data were collected,and a retrospective study was performed, whereas the plain abdominalradiography were graded with Radiographic Duke Abdominal AssessmentScale.Results Radiographic Duke Abdominal Assessment Score of cases inBell stageⅠ, Bell stage Ⅱ and Bell stage Ⅲ were3.72±1.634points,5.49±1.882points,8.84±2.375points, respectively, which were significantdifferent from each other (P＜0.05). The curative ratio of Bell stageⅠ, Ⅱ,and Ⅲ was66.7%(78/117),53.9%(41/76）and20.0%(5/25）, respectively.There was no obvious difference between the prognosis of Bell stageⅠandⅡ(P＞0.05), whereas dramatic differences were found, compared with the stage Ⅲ (P＜0.05). Logistic regression about prognosis indicatedy=1.139+0.822x1-0.678x2-0.608x3(Bell’s stage: x1,PLT: x2,Sepsis: x3).Conclusions Bell’s stage was identified closer related to NEC’sprognosis. The higher Bell’stage, the severer abdominal assessment score.For using Radiographic Duke Abdominal Assessment Scale better in NECdiagnosis and prognosis, we suggest, score0-1defined as normalabdominal X-ray, alert NEC, score2-4known as mild abdominal X-ray,score5-6as moderate abdominal X-ray, and score7-10named as severeabdominal X-ray. Combining abdominal radiography and ultrasonographyis helpful for reducing misdiagnosis of NEC.
