内镜超声弹性成像对消化道肿瘤淋巴结转移的诊断价值初探

目的 探讨内镜超声弹性成像在消化道肿瘤淋巴结转移判断中的价值.方法 应用内镜超声弹性成像技术对35例食管癌和胃癌患者共39个腹腔淋巴结、26个纵隔淋巴结进行检查,1～3分诊断为阴性淋巴结(良性淋巴结),4、5分诊断为阳性淋巴结(恶性淋巴结).与手术病理结果进行比较,评价内镜超声弹性成像的诊断价值.结果 65个淋巴结经内镜超声弹性成像诊断阴性淋巴结16个,阳性淋巴结49个.术后病理证实,内镜超声弹性成像诊断阳性淋巴结的敏感性为91.1%(41/45),特异性为60.0%(12/20).结论 内镜超声弹性成像有助于对肿瘤转移淋巴结的诊断.

EUS elastrography in lymph node staging of gastrointestinal tumor

Objective To evaluate the diagnostic value of endoscopic ultrasonic elastography in lymph node staging of gastrointestinal tumors.Methods Thirty-nine abdominal lymph nodes and 26 mediastinal lymph nodes of 35 patients with gastric cancer or esophageal carcer were examined by endoscopic ultrasonic elastography of five-point elastic score.Lymph node at 1-3 points was regarded as negative(benign),while 4-5 points as positive(malignant).The diagnostic value of EUS elastography was determined by comparing the results with pathological findings.Results Of all the 65 lymph nodes,49 were diagnosed as positive and 16 negative.The sensitivity and specificity of EUSE in the diagnosis of malignant lymph nodes were 91.1%and 60.0%.respectively.Conclusion EUSE is helpful for diagnosis of malignant metastasic lymph nodes.
