CT定位后经支气管镜肺活检对周围型肺癌的诊断价值

Value of transbronchial lung biopsy under CT positioning in the diagnosis of peripheral lung cancer

目的探讨CT肺段定位后经支气管镜肺活检(TBLB)对周围型肺癌的诊断价值。方法对35例疑似周围型肺癌患者参照CT肺段定位行TBLB。结果确诊周围型肺癌18例(51.4%),腺癌8例,腺鳞癌2例,鳞癌6例,未定型2例;肺良性病变11例,其中非特异性炎7例(20%)、坏死性炎3例(8.5%),结核1例(2.8%),阴性6例(17.1%),总确诊率82.9%。结论 CT肺段定位后TBLB能显著提高周围型肺癌的诊断阳性率,安全且并发症少。

Objective To investigate the diagnostic value of transbrochial lung biopsy （TBLB） by CT lung segments positioning in peripheral lung cancer. Methods 35 patients with suspected peripheral lung cancer underwent TBLB by CT lung segment positioning. Results 18 cases （51.4% ） were identified as peripheral lung cancer, including 8 cases of adenocarcinoma, 2 cases of adenosquamous carcinoma, 6 cases of quamous cell carcinoma, and 2 cases of undertermined pathology; 11 cases of benign pulmonary lesions included 7 cases （20%） of non-specific inflammation, necrotizing inflammation in 3 cases （8.5%）, and tuberculosis in 1 case （2. 8% ）. There were 6 cases of being negative （ 17. 1% ） with the total diagnostic rate of 82.9 %. Conclusion TBLB by CT lung segments positioning is a better method, which can significantly improve positive rate of peripheral lung cancer. It is safe with few complications.
