【摘要】 探讨在超声引导下经皮胸腔细针吸取活检对肺外周型肿块、肺的弥漫性病变和纵隔肿块细胞学、病理学诊断的临床应用价值。方法:选择68例影像学检查提示肺外周型肿块、肺弥漫性病变或纵隔肿块,而痰细胞学和支气管镜检查阴性的病例。应用 ALOKA-SSD 650实时灰阶超声仪。采用日本18G与 21G细针活检。 68例全部做细胞涂片,40例除做涂片外同时吸取组织块做石蜡切片。计算敏感性,特异性,准确性。结果:经细胞学、组织学两种方法诊断恶性肿瘤43例,仅细胞学诊断为恶性肿瘤40例,良性病变28例,其中3例假阴性。细胞学检查敏感度为93%,特异性100%。细胞学总准确率为95.6%。被检查者无气胸或出血等合并症。结论:该方法简便、迅速、安全且准确。尤其对细支气管肺泡癌的诊断更有帮助。更多还原

【Abstract】 To evaluate the practical value of ultrasonically-guided transcutaneous thoracic fine needle aspiration biopsy on peripheral lung tumor, pulmonary diffusive lesions, and mediastinal tumors. Methods:68 cases with pulmonary peripheral tumor from our hospital were selected and all were followed up and checked, of which 40 cases had also been diagnosed by histopathology for comparison with the cytological results respectively. Results: In all the above 68 cases, 43 were malignant and the rest benign. In the 43 malignant cases, 40 were detected by the cytological method alone, showing that the susceptibity was 93%, the specificity was 100% and total accuracy rate was 95.6 % in this series. There was also no patient that had any complications including pneumothorax or thoraco-bleeding during and after the aspiration biopsy. Conclusion: It is suggested that the ultrasonically-guided transcutaneous fine needle aspiration biopsy is a relatively simple, safe and reliable method for diagnosing thoracic tumors which could not be approached by endoscopy. If accompanied with histological examination it will be more accurate.更多还原
