经支气管肺活检(TBB)的诊断效果部分取决于活检标本大小,但是反映活检标本大小的客观参数尚未充分确定。为探讨7个参数与3种病理诊断之间的相关意义,对116例进行诊断性TBB的患者作了临床资料和肺组织病理切片研究。这7个参数包括临床检查:年龄、性别、胸部X线浸润;病理形态学所见:所取组织块总数、肺泡总数(每个活检标本)、总组织面积(肺泡性加非肺泡性的)以及肺总面积(仅肺泡组织)。3种病理诊断为:感染、肿瘤及非特异性纤维化和慢性炎症诊断。胸部X线浸润分为局限性或弥漫性,肿瘤结节归于局限性浸润。
The diagnostic value of bronchoscopic lung biopsy (TBB) depends in part on the size of the biopsy specimen, but the objective parameters that reflect the size of the biopsy specimen have not yet been fully defined. To explore the relationship between the seven parameters and the three pathological diagnoses, clinical data and lung histopathology were studied in 116 patients with diagnostic TBB. The seven parameters include clinical examination: age, gender, chest X-ray infiltration; pathological findings: the total number of tissue pieces taken, total number of alveoli (per biopsy), total tissue area (alveolar plus non-alveolar) As well as the total lung area (alveolar tissue only). Three kinds of pathological diagnosis: infection, tumor and non-specific fibrosis and chronic inflammation diagnosis. Chest X-ray infiltration is divided into limitations or diffuse, tumor nodules due to localized infiltration.
