用纤维支气管镜和硬质胸腔镜，对１３０例恶性胸腔积液患者作胸膜腔检查，总诊断率达９１．５％。组织病理确诊为胸膜间皮瘤２４例，占９６．０％；转移癌９５例，占９０．５％。经内窥镜向６９例患者胸膜腔内喷撒滑石粉，１０例喷撒四环素，１０例喷撒短小棒状杆菌疫苗。３组获得完全持久胸膜固定成功率分别为８７．０％、５／１０和８／１０。术后并发症有短暂发热和胸痛，６例出现局限性皮下气肿，４例发生胸腔引流部位肿瘤种植。作者认为，本法对恶性胸水病因诊断和剖胸探查术前估计有较高临床实用价值；经胸腔镜喷撒药物作胸膜固定术，是控制恶性胸液的有效措施；滑石粉疗效高，价廉，副作用少，值得推广。
With fiberoptic bronchoscopy and rigid thoracoscopy, pleural cavity examination was performed on 130 patients with malignant pleural effusions. The total diagnosis rate was 91.5%. Histopathology confirmed 24 cases of pleural mesothelioma, accounting for 96.0%; 95 cases of metastatic carcinoma, accounting for 90.5%. Endoscopically sprayed talcum powder into the pleural cavity of 69 patients, tetracycline was sprayed in 10 cases, and Corynebacterium parvum vaccine was sprayed in 10 cases. The success rate of complete permanent pleural fixation in the 3 groups was 87.0%, 5/10 and 8/10, respectively. Postoperative complications included transient fever and chest pain, 6 cases of subcutaneous emphysema, and 4 cases of thoracic drainage. The author believes that this method has high clinical and practical value for the preoperative diagnosis of malignant pleural effusion diagnosis and thorax exploration. The use of thoracoscopic surgery to spread the drug for pleurodesis is an effective measure to control malignant pleural fluid; talcum powder has a high curative effect. Inexpensive, less side effects, worth promoting.
