EUS elastrography in lymph node staging of gastrointestinal tumor / 中华消化内镜杂志

ABSTRACT

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.
