目的研究胸段食管癌淋巴结转 移螺旋CT的临床诊断价值，为今后临床诊 断提供参考与借鉴，提高对胸段食管癌淋 巴结转移的诊断水平。方法 以我院收治 的80例胸段食管癌淋巴结转移患者为研究 对象，根据其临床资料进行回顾性分析和 总结，探讨螺旋CT诊断胸段食管癌淋巴结 转移的临床价值。结果 CT诊断胸段食管 癌淋巴结转移的灵敏度为84.2%，特异性 为78.3%，准确率为82.5%，与病理检查结 果相比，p＜0.05，差异无统计学意义； 胸上段中以最上纵隔组、气管旁组最多， 分别为42.9%、33.3%；胸中段中以最上 纵隔组、气管旁组、隆突下组最多，分 别是22.9%、37.5%、25.0%；胸下段中以 贲门旁组、胃左动脉旁组最多，分别是 54.5%、27.2%。结论 螺旋CT诊断胸段食 管癌淋巴结转移具有重要的临床价值，其 影像具有一定的特征性，能够提高诊断正 确率，可以清楚显示淋巴结的转移与否， 能够为临床治疗提供重要的参考依据，具 有较高的临床使用价值。

Objective To discuss the clinical value of spiral CT in diagnosing thoracic segment esophageal cancer lymph node metastasis, to provide reference basis for future clinical practices, and to improve the level of the diagnosis of thoracic segment esophageal cancer lymph node metastasis. Methods Eighty patients with thoracic segment esophageal cancer lymph node metastasis admitted by the Hospital during the period from January, 2010 to January, 2014 were selected as research subjects, retrospective analysis and summary were made according to clinical data, and clinical value of spiral CT in the diagnosis of thoracic segment esophageal cancer lymph node metastasis was explored. Results The sensitivity, specificity and accuracy rate of CT diagnosis in the diagnosis of thoracic segment esophageal cancer lymph node metastasis hit 84.2%, 78.3% and 82.5% respectively, the differences were not statistically significant when compared to results of pathological examination (p<0.05). The number of top mediastinal juxta-groups and paratracheal juxta--groups in the upper thoracic portion was the most, hitting 42.9% and 33.3% respectively, and the number of mediastinum groups, paratracheal juxta-groups and submental juxta-groups in the mid-thoracic portion was the most, hitting 22.9%, 37.5% and 25.0% respectively, and the number of cardia juxta-group and left gastric arteries in the lower thoracic portion was the most, hitting 54.5% and 27.2% respectively. Conclusions Spiral enhanced CT delivers important clinical value in the diagnosis of thoracic segment esophageal cancer lymph node metastasis, its images possess certain characteristics, and it can improve the diagnostic accuracy, clearly show the metastasis availability of lymph nodes, and provide important diagnostic basis for clinical treatment, being worth of wide application and promotion in clinical practices.
