Abstract：Objective To investigate the application value of MSCT in the diagnosis of neonatal esophageal atresia and tra-cheoesophageal fistula.Methods The MSCT images of 48 patients with esophageal atresia who were treated in our hospital were collected,the original images were reconstructed by MPR,MinIP and VR and the conditions of esophageal atresia and tracheo-esophageal fistula were observed.Kappa consistency analysis was performed on the degree of conformity between MSCT and intra-operative judging of Gross classification and type Ⅲ fistula location,and the distance between the two blind ends of type Ⅲ esophageal atresia measured by MSCT was compared with intraoperative findings.Correlation analysis was performed on MSCT and intraoperative findings.Results Among the 48 patients with esophageal atresia,the accuracy rate of MSCT in judging Gross classification was 89.6％(43/48),and there was relatively strong consistency between MSCT and intraoperative classification(Kappa=0.774,P<0.001).Among the 46 patients with type Ⅲ esophageal atresia,the accuracy rate of MSCT in judging the loca-tion of the fistula was 82.6％(38/46),and there was moderate consistency between MSCT and intraoperative judgment on the lo-cation of the fistula(Kappa=0.480,P<0.001).There was no significant difference in the distance between the two blind ends of type Ⅲ esophageal atresia measured by MSCT compared with the intraoperative findings(P>0.05).There was a relatively high positive correlation between MSCT classification of esophageal atresia and intraoperative classification(r=0.786,P<0.001),and there was a moderate positive correlation between MSCT in judging the location of fistula in type Ⅲ cases and intraoperative find-ings(r=0.558,P<0.001),there was a relatively high positive correlation between the distance between the two blind ends of type Ⅲ esophageal atresia measured by MSCT and the intraoperative findings(r=0.739,P<0.001).Conclusion MSCT has great ad-vantages in the diagnosis of esophageal atresia and can provide an important reference for clinical treatment planning.
