On the Value of Esphagogram and CT Scan after Esphagogram in Diagnostic of Pyriform Sinus Fistula

摘要:目的:通过食管吞钡造影及造影后CT平扫检查提高梨状窝瘘的诊断率。方法:平卧位左、右、前、后斜位和头低足高位食管吞钡后透视观察有无钡剂外漏后,行CT平扫检查。扫描范围上起口咽部,下至胸骨上窝,层距厚3 mm。扫描后图像作多层面重建处理。结果:透视下见到瘘管3例,另3例经CT多层面重建隐约见到瘘管,但14例均可见漏出的钡剂滞留影,可判断瘘管的存在。结论:食管吞钡造影及造影后CT平扫可提高对梨状窝瘘诊断的敏感性和诊断率。Abstract: Objective: To improve the diagnosis rate of the pyriform sinus fistula by means of esphagogram and CT scan after esphagogram. Methods:To observe whether there is the leakage of barium by Xray check after barium swallowed in the five positions of body, followed by CT scan. The scanning ranges from oropharyngeal to Waterloo on sternum. The thickness is 3mm. The image is dealt with multidimensional reconstruction after the scan. Results:Among fourteen cases, the fistula can be seen in three, and be indistinctly seen after the multidimensional reconstruction of CT scan in the other three ones. All The fourteen cases show the trace of the leakage of barium, which helps to prove the existence of pyriform sinus fistula. Conclusions: Esphagogram and CT scan after esphagogram contribute the sensitivity of the diagnosis of pyriform sinus fistula, and improve the diagnosis rate.
