可弯曲内科胸腔镜对不明原因胸腔积液的诊断价值

目的探讨可弯曲内科胸腔镜技术对不明原因胸腔积液的诊断价值。方法对所有经过相关影像学、血生化检查以及胸腔穿刺进行胸水常规、生化、微生物学、细胞学、胸膜病理学等检查，仍不能明确其积液原因的113例患者进行可弯曲内科胸腔镜检查。结果恶性肿瘤48例（42．5％），结核42例（37．2％），普通炎症20例（17．7％），不明原因3例（2．7％）。常见的并发症主要是疼痛，这些并发症均可控制，手术无一例出现严重并发症。结论可弯曲内科胸腔镜检查对不明原因胸腔积液的诊断是一项安全、敏感性和特异性均极高的检查方法，但不应作为首选。

Diagnostic value of flexi-rigid medical thoracoscopy to pleural effusion with unknown reason

Objective To investigate the applicatiol/of flexi-rigid medical thoraeoscopy in the diagnosis of pleural effu- sion with unknown reason. Methods Flexi-rigid medical thoracoscopy was done in 113 patients with pleural effusions of un- known reason,that had done with routine examinations of the pleural effusions, including biochemistry,microbiology,cytology and pleural biopsy were done by thoraeentesis, as well as chest imageology and biochemistry of blood had failed to reach a defi- nite diagnosis. Results Malignancy was confirmed in 48 cases （42.5%）, tuberculous pleurisy was 42 cases （37.2%） ,parap- neumonic effusion was 20 cases （17.7%）, negative was 3 cases （2.7%）. The most common complication was pain, which was re- lieved by symptomatic treatment. There was no serious complication. Conclusion Flexi-rigid medical thoracoscopy is a safe, and high diagnostic rate method ,but not a first choice in unknown reason pleural effusions.
