对病因不明的胸腔积液常需作组织病理检查,但盲目针穿活检结果不可靠,而胸腔镜检查术既不困难还很安全,作者等乃于1970～1977年中给为胸腔积液查明病因的172例,大部伴发胸腔积液的肺内阴影而气管镜阴性结果的32例,以及胸腔内异物切除与再发性气胸而作胸膜固定者各2例共208例作了胸腔镜检查。胸腔镜检查下发现恶性病变的外形从单个小结到广泛分布的癌症都有;胸膜表面有的粗糙不平,有的散在着带白色或微红色单个或多皱融合片样病变。肺内肿瘤有时在肺表面亦能见到,脏层胸膜时伴有线条
Of unknown etiology pleural effusion often need to make histopathological examination, but the blind needle biopsy results are not reliable, and thoracoscopy is neither difficult nor very safe, the author was in the period of 1970 to 1977 to pleural effusion check 172 cases of etiology, most of the lungs with pleural effusion and bronchoscopy negative results in 32 cases, as well as intrathoracic foreign body resection and recurrent pneumothorax and pleurodesis were 2 cases of 208 cases of pleural cavity Mirror examination. Thoracoscope found that the appearance of malignant lesions from a single small nodules to widely distributed cancer have; pleural uneven surface, and some are scattered with white or reddish single or polyglonal fusion-like lesions. Pulmonary tumors are sometimes seen on the surface of the lungs, with visceral pleura
