The value of preoperative CT scan in newborns with type C esophageal atresia.

PURPOSE

This study was designed to evaluate the accuracy of preoperative CT scan in depicting the structure of type C esophageal atresia (EA) and determine its role in planning the surgical strategy by digitally measuring the interpouch distance.

METHODS

Thirty-five neonates (20 males, 15 females) born with type C EA were enrolled in this study. A helical CT scan was performed after chest radiographs of the neonates with a coiled oroesophageal tube in the upper esophageal pouch. The interpouch distances measured on CT images were compared with the findings at surgery.

RESULTS

With the use of helical CT scan, the structure of EA-TEF was accurately depicted; the origins of the fistula and the interpouch distance were defined. The interpouch distance detected by CT scan correlated well with the findings at surgery. Statistical analysis demonstrated no significant difference (R = 0.99, P < 0.001). CT scan findings were crucial in planning the surgical strategy in 14 patients (40%).

CONCLUSION

Preoperative CT scan could provide more accurate information about the origin of the fistula and the interpouch distance in type C EA and played a crucial role in planning the surgical strategy.
