In summary, knowledge of the exact location of lymph nodes in mediastinum and hilar areas and their relationship to the puncture site of TBNA is the first step to a successful TBNA. The necessity to determine the N3 status and multistation status of patients with bronchogenic carcinoma being evaluated for surgery and the current financial restraint of the medical care system further highlight the potential of this simple, effective, and safe procedure. TBNA can markedly enhance the diagnostic yield of flexible bronchoscopy. TBNA and PCNA are complimentary procedures.
总之，了解纵隔和肺门区域淋巴结的确切位置及其与经支气管针吸活检（TBNA）穿刺部位的关系是成功进行TBNA的第一步。对于接受手术评估的支气管源性癌患者，确定N3状态和多站状态的必要性以及医疗保健系统当前的财务限制进一步凸显了这种简单、有效且安全的操作的潜力。TBNA可以显著提高柔性支气管镜检查的诊断率。TBNA和经皮针吸活检（PCNA）是互补的操作。
