咯血是呼吸系统疾病中较常见的症状,大约10～15%的胸部病人是由于咯血就医的。但经体检及胸部X线检查并无阳性发现。一些间接检查方法虽然对咯血原因及出血部位的判定可有帮助,但确诊往往决定于经纤维支气管镜(以下简称纤支镜检)进行组织学及细胞学检查的结果。大约50%的肺癌病人有咯血症状。有些肺癌病人(2—16%)胸部X线检查无异常发现,痰内癌细胞检查亦属阴性,而仅有咯血症状。因此,对咯血病人进行纤支镜检在肺癌早期诊断中具有重要意义。那么,哪些因素表示肺癌高度可能而需行纤支镜检,以及哪些咯血病人不宜应用纤支镜检?本文仅就这些问题将454例咯血病人的镜检结果,进行分析.
Hemoptysis is a more common symptom of respiratory diseases. About 10-15% of thoracic patients are admitted for hemoptysis. However, no physical examination and chest X-ray examination found no positive. Although some indirect examination of hemoptysis and bleeding sites may determine the decision can be helpful, but the diagnosis is often determined by the bronchoscopy (hereinafter referred to as bronchoscopy) for histological and cytological examination results. About 50% of lung cancer patients have hemoptysis. Some lung cancer patients (2-16%) chest X-ray examination found no abnormalities, sputum cancer cell test is negative, but only hemoptysis. Therefore, the hemoptysis patients with bronchoscopy in the early diagnosis of lung cancer is of great significance. So, what factors that lung cancer is highly likely to be required fiberoptic examination, and which patients with hemoptysis should not be applied bronchoscopy? This article only 454 patients with hemoptysis on these issues microscopic examination results were analyzed.
