目的:探讨分析CT引导下经皮穿刺活体组织检查的操作方法及其对诊断肺癌的诊断价值。方法:选取2010年2月～2012年10月间我科收治的46例肺部有不明肿块的患者作为研究对象,对其进行CT引导下经皮穿刺活体组织检查,并将穿刺的情况、检查结果及其临床资料进行回顾性的分析。结果:对这46例患者进行CT引导下经皮穿刺活体组织检查,穿刺成功的患者有46例,穿刺失败的患者有0例,穿刺成功率为100%,检查结果的阳性率为100%。其中,肺内不明肿块属于恶性肿瘤的患者有42例,肺内不明肿块属于良性肿瘤的患者有4例,属于鳞癌的患者有19例,属于腺癌的患者有14例,属于小细胞癌的患者有6例,属于腺鳞癌的患者有2例,属于大细胞癌的患者有1例。在这46例患者中,发生穿刺并发症的患者有6例,其中咳吐血痰的患者有4例,发生气胸的患者有2例。结论:CT引导下经皮穿刺活检可对肺部的不明肿块进行准确的诊断,尤其在诊断肺癌方面有着十分重要的临床价值,值得在临床上推广应用。
OBJECTIVE: To explore the method of operation for percutaneous needle biopsy under CT guidance and its diagnostic value in diagnosing lung cancer. Methods: From February 2010 to October 2012 in our department 46 cases of lung cancer patients with unknown mass as a study object, its CT-guided percutaneous biopsy, and the puncture, check Results and clinical data were retrospectively analyzed. Results: According to CT guided percutaneous needle biopsy, 46 cases were successfully punctured, 0 failed puncture and 100% puncture. The positive rate was 100%. Among them, there are 42 patients with malignant tumor of unknown mass in the lung, 4 patients with benign tumor in the lung, 19 patients with squamous cell carcinoma, 14 patients with adenocarcinoma and 14 patients with small cell carcinoma Of the 6 patients, 2 patients with adenosquamous carcinoma, and 1 patient with large cell carcinoma. Of the 46 patients, 6 developed complications of puncture, including 4 cough and bloody sputum, and 2 pneumothorax. Conclusion: CT-guided percutaneous biopsy can accurately diagnose the unidentified lumps in the lungs, especially in the diagnosis of lung cancer. It is worth to be popularized clinically.
