胸腔镜最初用于诊断,并广泛用于结核性胸膜粘连松解术,随着有效化疗之应用而趋于废弃,而最近又采用直式胸腔镜与以可曲性纤支镜代替胸腔镜检查,并进行诊断效果比较。选择原因不明的胸水患者30例,前10例只用直式胸腔镜(前视外径9mm Storz 胸腔镜)。继之用直式胸腔镜和纤支镜随意顺序检查20例(PentaxFB19H,外径5.9mm)选择相同的病变部位活检。胸 Thoracostomy was originally used for diagnosis and is widely used in tuberculous pleural adhesion lysis, which has become obsolete with the use of effective chemotherapy, and has recently adopted straight thoracoscopy and flexible bronchoscopy in place of thoracoscopy , And compare the diagnostic results. Thirty patients with unexplained pleural effusion were selected. The first 10 patients were treated by straight thoracoscopy (anterior diameter 9 mm Storz thoracoscopy). Followed by direct thoracoscopy and bronchoscopy random order check 20 cases (PentaxFB19H, diameter 5.9mm) to select the same lesion biopsy. chest
