MSCT引导下行肺穿刺活检对肺部肿块的诊断有效性及安全性评价

目的：探讨MSCT引导下行肺穿刺活检对肺部肿块的有效性及安全性,为临床提供参考。方法：选取2013年4月-2014年4月本院住院的150例MSCT引导经肺穿刺活检患者,在手术之前进行常规CT胸部扫描后,进行MSCT引导下进行肺穿刺活检,观察其结果。结果：150例患者均穿刺成功。其中,经手术、病理检查后为恶性肿瘤的有104例,46例患者为良性病变。在恶性肿瘤及良性肿瘤患者中,敏感性或者特异性分别为92.3%、89.1%。病灶直径〈3 cm、3~5 cm、〉5 cm的敏感性分别为79.2%（19/24）、95.8%（46/48）、93.3%（28/30）,将3~5 cm与〈3 cm的敏感性对比分析后,差异有统计学意义（x^2=9.142,P〈0.05）;其他直径之间及距胸膜距离之间对比分析后,差异无统计学意义（P〉0.05）。在150例患者中,进行传统CT检查、MSCT检查出现并发症的患者有30例、10例,发生率分别为20.0%、6.7%,对比分析后,差异有统计学意义（x^2=10.382,P〈0.05）。所有气胸患者经过吸氧、卧床休息后,对胸片进行检查后,气胸能够完全吸收,咳血患者经过保守治疗后病情痊愈。结论：MSCT引导经肺穿刺活检手术是一种较为安全、准确的方式,对肺部肿块的诊断具有重要的临床意义,值得大力推广。

The Efficacy and Safety Evaluation of MSCT Guided Lung Biopsy for the Diagnosis of Pulmonary Tumor

Objective：To observe the efficacy and safety evaluation of MSCT guided lung biopsy for the diagnosis of pulmonary tumor. Method： 150 cases of patients were selected by our hospital from April 2013 to April 2014 for MSCT guided lung biopsy.Before operation the patients were used routine chest CT scan and MSCT guided lung biopsy under,then the result were observed.Result：150 cases of patients were successful after puncture.Which,after surgery for cancer there after pathological examination 104 cases,46 cases of patients with benign lesions,in patients with malignant and benign tumors, the sensitivity or specificity were respectively 92.3% and 89.1%. Lesion diameter 〈3 cm,3-5 cm and 〉5 cm sensitivity were respectively 79.2%（19/24）, 95.8%（46/48） and 93.3%（28/30）,the 3-5 cm and 〈3 cm sensitivity after comparative analysis, the difference was statistically significant（ x^2=9.142,P〈0.05）;comparing the analysis, the difference between the diameter and the distance between the other statistically significant distance pleura（P〉0.05）. In 150 patients, the traditional CT examination, MSCT examination complications had occurred in patients respectively 30 cases, 10 cases, the incidence was respectively 20.0% and 6.7%, after the comparative analysis, the difference was statistically significant（ x^2=10.382,P〈0.05）. All pneumothorax patients treated after oxygen,bed rest and checking on the chest, pneumothorax can be completely absorbed, hemoptysis patients recovered after conservative treatment condition. Conclusion：MSCT guided lung biopsy surgery is a relatively safe and accurate manner, has important clinical implications for the diagnosis of lung tumor and worth promoting.
