Abstract：Objective To study the use of the multi-slice CT (MSCT) and 3D post-processing reconstruction techniques in the
preoperative assessment of neonatal type Ⅲ esophageal atresia. Methods MSCT data of 32 children with congenital type Ⅲ
esophageal atresia were retrospectively analyzed. All children underwent esophagography to clarify the diagnosis and then MSCT
was used, with adequate preparation before the examination, and the images were given 3D post-processing reconstruction after the
examination for a controlled study with the surgical findings. Results 32 cases underwent MSCT examination clearly showed the
location of the proximal esophageal atresia, 30 cases showed that the distal esophageal tracheal fistula location. Of them, the fistula
openings were located in the lower trachea in 25 cases, in the carina in 4 cases, and in the left main bronchus in 1 case. The distance
between the two blind ends of the esophagus was accurately measured, according to Gross classification, 5 cases were diagnosed
type Ⅲa and 25 were typeⅢb. The results were consistent with what seen in the surgery operation. 2 cases left could not clearly show
the location of the distal fistula. At the same time, 29 patients had pulmonary inflammation, 8 had abnormal tracheal development,
1 had thoracic deformity and 2 had congenital heart disease. Comparing the results of MSCT and surgery, the consistency of Kappa
value in showing fistula was 0.819; the Kappa value in showing classification was 0.824. The consistency of the two results was
very good. Conclusion MSCT can accurately diagnose type Ⅲ esophageal atresia in neonates. Through adequate preparation before
scanning and 3D post-processing and reconstruction of CT images, it can fully display the location of the distal esophageal fistula,
accurately measure the distance between the two blind ends of the esophagus, and accurately classify. It can provide a reliable
imaging basis for clinical formulation of surgical plans.
