We evaluated the usefulness of ultrasonography under thoracoscopy for locating pulmonary nodules and measuring the size of mediastinal and hilar lymph nodes. Using unilateral lung ventilation with a double lumen tracheal tube, ultrasonography was effective in evaluating the condition of completely collapsed lungs. The locations of twelve nodules, including five lung cancers, six inflammatory lesions, and one intra-pulmonary lymph node, with sizes ranging from 4 to 30 mm, were examined by ultrasonography. While all lung cancers and the intra-pulmonary lymph node were located by ultrasonography, only two of six inflammatory lesions were found. In examining mediastinal and hilar lymph nodes, all lymph nodes larger than 10 mm could be seen by ultrasonography. However, the ultrasonography could not distinguish between metastatic and non-metastatic lymph nodes. In conclusion, ultrasonography under thoracoscopy was able to locate pulmonary nodules larger than 10 mm, especially lung cancers, and was able to measure the size of mediastinal and hilar lymph nodes larger than 10 mm.
我们评估了胸腔镜检查下超声检查对定位肺结节以及测量纵隔和肺门淋巴结大小的实用性。使用双腔气管导管进行单侧肺通气时，超声检查对于评估完全萎陷肺的状况有效。通过超声检查对12个结节的位置进行了检查，这些结节包括5个肺癌、6个炎性病变和1个肺内淋巴结，大小范围为4至30毫米。虽然所有肺癌和肺内淋巴结均通过超声检查得以定位，但6个炎性病变中仅发现2个。在检查纵隔和肺门淋巴结时，超声检查能够看到所有大于10毫米的淋巴结。然而，超声检查无法区分转移性和非转移性淋巴结。总之，胸腔镜检查下的超声检查能够定位大于10毫米的肺结节，尤其是肺癌，并且能够测量大于10毫米的纵隔和肺门淋巴结的大小。
