Clinical value of sagittal CT scanning in neonates with congenital esophageal atresia and tracheoesophageal fistula / 实用放射学杂志

ABSTRACT

Objective To explore the clinical value of sagittal CT scan in the diagnosis of congenital esophageal atresia and tracheoesophageal fistula(CEA-TEF).Methods Sagittal CT scanning was performed in 1 7 neonates with clinically suspected CEA-TEF preoperatively. Post-processing methods included multiple planar reconstruction(MPR)and volume rendering(VR).The CT manifestations were compared with the surgical findings.Paired-samples t test and Kappa identity analysis were used to analyze the consistency between two esophageal pouches and position of fistula.Results Among 1 7 cases,sagittal CT images clearly showed the distance between two esophageal pouches and position of fistula.Based on Gross classification,2 cases were included in type ⅢA(11.8%),and 15 cases in type ⅢB(88.2%).The results were satisfactory with the surgical findings with 100% accuracy.The distance between two esophageal pouches determined by VR and MPR had no remarkable differences(t=0.991,P>0.05).The position of fistula determined by VR and MPR had high consistency with the surgical findings (Kappa≥0.75).Conclusion Sagittal CT scanning can significantly limit scanning range and reduce the radiation dose as well as improve image quality,and accurately display and assess the distance between two esophageal pouches and position of fistula in CEA-TEF.It has important application value in diagnosing CEA-TEF in neonates.
