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.
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.
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%).
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.
本研究旨在评估术前CT扫描在描绘C型食管闭锁（EA）结构方面的准确性，并通过数字测量囊袋间距离来确定其在制定手术策略中的作用。
本研究纳入了35例C型EA新生儿（男20例，女15例）。在新生儿上食管囊袋内置入盘绕的食管气管导管后进行胸部X线摄影，随后行螺旋CT扫描。将CT图像上测量的囊袋间距离与手术结果进行比较。
通过螺旋CT扫描，准确描绘了EA-TEF的结构；明确了瘘管的起源和囊袋间距离。CT扫描检测到的囊袋间距离与手术结果相关性良好。统计分析显示无显著差异（R = 0.99，P < 0.001）。CT扫描结果对14例患者（40%）的手术策略制定至关重要。
术前CT扫描可为C型EA瘘管起源和囊袋间距离提供更准确的信息，并在手术策略制定中发挥关键作用。
