CT联合食管造影诊断食管癌的影像价值评估

Imaging value of CT combined with esophagography in the diagnosis of esophageal carcinoma

目的:分析研究针对食管癌采用CT联合食管造影诊断体现出的影像价值。方法:选取2017年1月至2022年6月在我院收治的经病理证实的126例食管癌患者,分别行CT及食管造影检查。结果:造影应用于早期食管癌的检出率要高于CT,应用于进展期检出率要低于CT;两者联合早期检出率无改善,进展期可提高检出率;食管癌放化疗后由于水肿及纤维化,造影评估有一定的假阳性,联合CT可提高疗效评估;造影对于术后吻合口狭窄、吻合口瘘的检出率明显高于CT;CT可发现狭窄的原因,通过造影再行CT检查,对造影难以发现的瘘口也有一定的显示;术后复发,两者联合提高检出率。结论:对于食管癌的诊断及治疗,CT联合食管造影可互补不足。

Objective: To analyze the imaging value of CT combined with esophagography in the diagnosis of esophageal cancer. Methods: From January 2017 to June 2022, 126 patients with esophageal cancer confirmed by pathology in our hospital were selected. CT, esophagography and combined examination were performed respectively.Results: The detection rate of angiography in early esophageal cancer was higher than that of CT, and the detection rate of advanced esophageal cancer was lower than that of CT. The early detection rate of the combination of the two could not be improved, but the detection rate could be increased in the progressive stage. There are some false positives in angiographic evaluation of esophageal cancer due to edema and fibrosis after chemoradiotherapy, which can be significantly improved by combined CT enhancement. The detection rate of postoperative anastomotic stenosis and anastomotic leakage by contrast-enhanced imaging was significantly higher than that by CT. The cause of stenosis can be found by CT, and the fistula that is difficult to be found by CT can also be shown. Postoperative recurrence, the combination of the two can improve the detection rate. Conclusion: For the clinical examination of esophageal cancer,CT combined with esophagography can improve the detection rate.
