目的通过肺针吸细胞病理学检验诊断新技术,探讨肺癌早期诊断及鉴别诊断的价值,进而达到肺癌早期诊断的目的。方法对112例肺部病变(肿块63例、结节41例、实变8例)进行CT引导下经皮肺穿刺细胞病理学诊断,采用22G穿刺针,精选最佳层面进针多部位取材,活检后行瑞-姬双染色,根据细胞学特征及结构特点及组织学检查,个别病例同时做抗酸染色。结果穿刺成功率99.1%,在112例中,肺恶性肿瘤74例,穿刺敏感性91.1%。特异性76.9%,假阴性8.9%,良性病变37例,均经手术及随访证实。结论CT引导下经皮肺细针针吸细胞病理学检验诊断具有创伤小、简单快速、安全可靠、准确率高,符合国情、便于推广,为临床肺癌早期诊断提供重要依据。
Objective To investigate the value of lung needle aspiration cytology test to diagnose the value of early diagnosis and differential diagnosis of lung cancer so as to achieve the purpose of early diagnosis of lung cancer. Methods 112 cases of pulmonary lesions (63 cases of nodules, 41 cases of nodules, consolidation of 8 cases) CT-guided percutaneous lung paracentesis cytopathology diagnosis, the use of 22G needle, the best selection of the best level needle into multiple parts After biopsy Rui - Ji double staining, according to cytology and structural features and histological examination, in individual cases at the same time do acid-fast staining. Results The successful rate of puncture was 99.1%. Among 112 cases, 74 cases of lung malignancies had a puncture sensitivity of 91.1%. Specificity of 76.9%, false negative 8.9%, benign lesions in 37 cases, were confirmed by surgery and follow-up. Conclusion CT guided percutaneous fine needle aspiration cell pathology test has the advantages of less trauma, simple and quick, safe and reliable, high accuracy, in line with national conditions, easy to promote, provide an important basis for the early diagnosis of clinical lung cancer.
