目的 探讨胸段食管鳞癌右喉返 神经旁淋巴结实施CT诊断价值。方法 采 用回顾性分析法，选取2013年5月至2014 年5月我院接受检查的50例食管鳞癌右喉 返神经旁淋巴结患者的CT影像资料，观察 患者右喉返神经旁淋巴结大小及位置，并 与术后病理结果进行比较分析。结果 经 过一系列的检查与分析，发现2mm层厚CT 中右喉返神经旁淋巴以短径6mm为诊断转 移最佳工作点，曲线下面积、敏感性及特 异性分别为0.833、74.1%、76.5%；5mm层 厚CT中右喉返神经旁淋巴以短径5mm为诊 断转移最佳工作点，曲线下面积、敏感性 及特异性分别为0.836、89.7%、64.1%； 肿瘤长度、位置及其他淋巴结转移与右 喉返神经旁淋巴是否有转移有显著的关 联性(P<0.05),差异具有统计学意义；右 喉返神经旁淋巴是否有转移与肿瘤T分期 和肿瘤分化程度之间没有明显的相关性 (P>0.05),差异没有统计学意义。结论 CT 诊断应用于胸段食管鳞癌右喉返神经旁淋 巴结中具有较高的诊断价值，而且5mm层 厚CT不劣于2mm层厚CT检测价值，二者均 能提高诊断准确率。

Objective To investigate right thoracic segment esophageal squamous carcinoma laryngeal recurrent nerve lymph nodes near the CT diagnostic value. Methods A retrospective analysis, selection in May 2013 to May 2014 in our inspection of 50 cases of esophageal squamous cell carcinomas right next to the laryngeal recurrent nerve lymph nodes in patients with CT image data, observation patient's right next to the laryngeal recurrent nerve lymph node size and location, and compared with postoperative pathological results analysis. Results After a series of check and analysis, found that the 2 mm thick CT right next to the laryngeal recurrent nerve lymph diagnosis transfer for short diameter 6 mm best working point, the area under the curve, the sensitivity and specificity were 0.833, 74.1%, 76.5%; 5 mm thick CT right next to the laryngeal recurrent nerve lymph diagnosis transfer for short diameter 5 mm best working point, the area under the curve, the sensitivity and specificity were 0.836, 89.7%, 64.1%; Length of tumor, location, and other lymph node metastasis and lymph is right next to the laryngeal recurrent nerve transfer has a significant correlation (P<0.05), statistically significant difference; Right next to the laryngeal recurrent nerve transfer and whether lymphatic tumor T stage and no significant correlation between degree of tumor differentiation (P>0.05), difference was not statistically significant. Conclusion CT is applied to the thoracic segment esophageal squamous carcinoma, laryngeal recurrent nerve right next to the lymph nodes has high diagnostic value, and 5 mm thick CT is not inferior to 2 mm thick CT detection value, both can improve the diagnostic accuracy.
