目的：探讨支气管肺活组织检查术对周围型肺癌的诊断价值。方法：通过支气管肺活组织检查术对５６例可疑周围型肺癌患者进行检查。结果：确诊肺癌３５例、炎症９例、结核６例、阴性６例，确诊率为８９．２９％，确诊周围型肺癌率为８５．３７％。结论：纤维支气管镜肺活检对周围型肺癌具有较高的诊断价值 Objective: To explore the diagnostic value of bronchial lung biopsy for peripheral lung cancer. Methods: 56 patients with suspicious peripheral lung cancer were examined by bronchopulmonary biopsy. Results: 35 cases of lung cancer, 9 cases of inflammation, 6 cases of tuberculosis, and 6 cases of negative diagnosis were confirmed. The diagnosis rate was 89.29%. The diagnosed peripheral lung cancer rate was 85.37%. Conclusion: Fiberoptic bronchoscopic lung biopsy has high diagnostic value for peripheral lung cancer
