目前诊断胸膜病变常用的方法是胸水检查和胸膜活检,但仍有20%左右的病人不能明确诊断。鉴于一部分病例的胸水是由肺癌所致,结核性胸膜炎也可能合并有肺(或支气管)结核,故此类病例的纤支镜检查当有一定的临床意义。为探讨纤支镜检查对原因不明胸水患者的诊断价值,今将70例检查情况作一简 At present, the common method for diagnosing pleural lesions is pleural effusion examination and pleural biopsy, but about 20% of patients are still unable to confirm the diagnosis. Given that some cases of pleural effusion are caused by lung cancer, tuberculous pleurisy may also have lung (or bronchial) tuberculosis. Therefore, the bronchoscopy of these cases should have some clinical significance. To investigate the diagnostic value of fibrobronchoscopy in patients with unexplained pleural effusions, we will make a brief review of 70 cases.
