目的评价气管镜内超声引导针吸活检术在修正非小细胞肺癌术后1年纵隔淋巴结肿大患者TNM分期的诊断价值。方法对36例非小细胞肺癌术后1年CT检查纵隔淋巴结肿大的患者行支气管内超声引导针吸活检术。结果 36例患者共穿刺46组淋巴结,其中淋巴结穿刺结果阳性者为31组,淋巴结穿刺阴性者为15组。22例患者确诊为术后纵隔淋巴结活检阳性。阳性率分别为61.11%(22/36)与67.39%(31/46)。一致性检验有统计学意义。结论气管镜内超声引导针吸活检术对非小细胞肺癌术后纵隔淋巴结肿大的患者有较高的诊断价值。
Objective To evaluate the value of endoscopic ultrasonography guided needle aspiration biopsy in the diagnosis of TNM staging in patients with mediastinal lymph node enlargement one year after operation of non-small cell lung cancer. Methods Thirty-six patients with non-small cell lung cancer who underwent one-year postoperative CT examination of mediastinal lymph nodes were treated with endobronchial guided needle aspiration biopsy. Results A total of 46 lymph nodes were punctured in 36 patients, of which 31 were positive for lymph node puncture and 15 were negative for lymph node puncture. Twenty-two patients were diagnosed as positive after mediastinal lymph node biopsy. The positive rates were 61.11% (22/36) and 67.39% (31/46) respectively. Consistency test was statistically significant. Conclusion Endoscopic ultrasonography guided needle aspiration biopsy has a high diagnostic value for postoperative mediastinal lymph nodes in patients with non-small cell lung cancer.
