中央型肺癌并阻塞性肺不张的超声诊断价值

Validation on the value of ultrasonography to central type lung cancer accompanied by obstructive atelectasis:compared with conventional X-ray and CT

目的 探讨超声在中央型肺癌并阻塞性肺不张的诊断价值。方法 随机选择 75 0例胸科患者行双盲同期胸部常规X线胸片、CT和超声检查。将三种方法对中央型肺癌并阻塞性肺不张病例的检出结果进行前瞻性比较。结果 超声、胸片对肺不张敏感性的比较以及超声、胸片、CT对不张肺内肿块显示和界定的比较差异均有显著性意义 (P <0 .0 0 5 ) ,对肿大淋巴结的检出超声不如CT。结论 中央型肺癌并阻塞性肺不张时 。

Objective To investigate the value of ultrasonography for diagnosing central type lung cancer accompanied by obstructive atelectasis.Methods In a prospective double blind randomized concurrent controlled trial,152 patients with central type lung cancers accompanied by obstructive atelectasis were examined with conventional radiography,CT and ultrasonography in turn.Results The sensitivity:⑴ To the atelectasis,X ray was 87.5%,ultrasonography 100% (P< 0.005 );⑵ To the masse surrouded with atelectasis:① the simple type,X ray was 35%,CT 80%,ultrasonography 92% (P< 0.005 );②the pleural effusions type,X ray 33%,CT 66%,ultrasonography 88% (P< 0.005 );⑶To the border of the masse:① the simple type,X ray 30%,CT 45%,ultrasonography 98% (P< 0.005 );②the pleural effusions type,X ray 16%,CT 32%,ultrasonography 94% (P< 0.005 );⑷ To the metastasis lymph nodes,X ray was 9 cases,CT 61 cases and ultrasonography 8 cases.Conclusions If ultrasonography is served to make up the defects that X ray and CT have,the accuracy can be further improved in diagnosing central type lung cancer accompanied by obstructive atelectasis.
