Abstract
Objective:To explore the diagnostic value of high-frequency ultrasound and mobile digital X-ray in neonatal necrotizing enterocolitis(NEC)and the consistency in staging of NEC,in order to provide reference for early clinical diagnosis and targeted intervention measures.Methods:The clinical data of 84 suspected NEC neonates(with abdominal distension,vomiting,bloody stool,etc.)who were treated in our hospital from Mar 2023 to Mar 2024 were retrospectively analyzed.After admission,they were all examined by high-frequency ultrasound and mobile digital X-ray,and the clinical comprehensive diagnosis(combining clinical symptoms,laboratory indicators,surgical pathology)results were used as the"gold standard"to compare the diagnostic results and efficacy of high-frequency ultrasound and mobile digital X-ray examinations alone and in combination for NEC.The consistency between the diagnostic results of the two methods for different stages of NEC and the clinical comprehensive diagnosis results was analyzed using Kappa value.Results:The comprehensive clinical diagnosis results showed that among 84 suspected NEC neonates,56 were positive and 28 were negative.Among the 56 cases of NEC,20 cases were in stageⅠ,25 cases in stageⅡ,and 11 cases in stage Ⅲ.The results of mobile digital X-ray examination showed that 43 were positive and 41 were negative.The results of high-frequency ultrasound examination showed that 45 were positive and 39 were negative.The results of high-frequency ultrasound combined with mobile digital X-ray diagnosis showed that 55 were positive and 29 were negative.The sensitivity and accuracy of high-frequency ultrasound combined with mobile digital X-ray examination for NEC diagnosis were higher than those of high-frequency ultrasound examination or mobile digital X-ray examination alone(P＜0.05).Moreover,the missed diagnosis rate of the combined detection was lower(P＜0.05).The results of mobile digital X-ray diagnosis showed that there were 17 cases in stageⅠ,16 cases in stage Ⅱ,and 10 cases in stage Ⅲ.The consistency Kappa value with the comprehensive clinical diagnosis results was 0.618(P＜0.01).The results of high-frequency ultrasound diagnosis showed that there were 17 cases in stage Ⅰ,18 cases in stage Ⅱ,and 10 cases in stage Ⅲ.The consistency Kappa value was 0.701(P＜0.01).The results of high-frequency ultrasound combined with mobile digital X-ray diagnosis showed that there were 20 cases in stage Ⅰ,23 cases in stage Ⅱ,and 12 cases in stage Ⅲ.The consistency Kappa value was 0.886(P＜0.01).Conclusion:High-frequency ultrasound combined with mobile digital X-ray can improve the diagnostic accuracy of NEC,and can be used clinically to assess the stage of NEC early,providing a reference for early clinical evaluation and diagnosis,as well as targeted intervention treatment plans.关键词
