高分辨CT在早期慢性阻塞性肺疾病的临床诊断研究(1)
[摘要] 目的 探讨高分辨CT在早期慢性阻塞性肺疾病中的临床诊断价值。方法 整群选取2014年2月—2015年10月在该院收治的确诊的早期慢性阻塞性肺疾病患者56例和同期健康体检者70例分别作为观察组和对照组,进行肺功能检查和高分辨CT检查和评价。结果 针对早期慢性阻塞性肺疾病患者,高分辨CT确诊敏感性为85.7%显著性高于肺功能检查的确诊敏感性28.6%,差异有统计学意义(P﹤0.05);观察组和对照组在肺功能检查指标FEV1、FEV1/FVCmax、TLC和RV上差异无统计学意义(P﹥0.05);观察组和对照组在高分辨CT的定量指标全肺、右肺和左肺E/L值上差异有统计学意义(P﹤0.05)。结论 高分辨CT在慢性阻塞性肺疾病的早期诊断中其应用价值明显高于肺功能检查,有重要的诊断价值,值得在临床诊断应用中进一步的推广。

[Abstract] Objective To study the value of high-resolution CT in clinical diagnosis of early chronic obstructive lung diseases. Methods 56 cases of patients diagnosed with early chronic obstructive lung diseases in our hospital from February 2014 to October 2015 and 70 healthy examined persons at the same period were selected as the observation group and the control group, and both groups were given lung function examination and high-resolution CT examination and evaluation. Results For patients with early chronic obstructive lung diseases, the diagnostic sensitivity of high-resolution CT was obviously higher than that of lung function examination(85.7% vs 28.6%), and the difference had statistical significance(P<0.05), and there were obvious differences in the high-resolution CT quantitative indexes such as whole-lung, right-lung and left-lung E/L values between the observation group and the control group with statistical significance(P<0.05). Conclusion The application value of high-resolution CT in early diagnosis of chronic obstructive lung diseases is obviously higher than that of lung function examination, and it is of important diagnostic value and it is worth further promotion in clinical diagnosis.

慢性阻塞性肺疾病(chronic obstructive pulmonary disease, COPD)主要特征是气道存在慢性炎症的病变,气流不可逆受限阻塞,是一种有极高发病率和致残、致死率的肺部疾病,可严重影响人们的工作生活质量,甚至威胁到人们的生命安全[1-2]。COPD发展至中晚期,其病死率和致残率均有显著性的增涨,因此,COPD的及早确诊、及时治疗显得尤为重要和急迫[3]。作为COPD临床确诊和分级主要手段的肺功能检查(pulmonary function test, PFT)在早期COPD检查中因其有敏感性较低、耐受性较差的缺点,从而存在着较高的漏诊率和误诊率[4]。高分辨CT(HRCT)具有较高的分辨率和耐受性,在细气管疾病的影像学评价和诊断中有着明显的优势,近年来有大量的临床研究和文献表明HRCT在COPD的诊断中有较高的应用价值[5-7],但在早期COPD的诊断中相应的临床报道有限。笔者研究并探讨HRCT检测在早期COPD的临床诊断价值,对2014年2月—2015年10在该院收治的确诊的早期慢性阻塞性肺疾病患者56例和同期健康体检者70例分别作为观察组和对照组进行对比分析,现报道如下。

1.1 一般资料
观察组为早期COPD患者,整群选择2014年2月—2015年10月该院收治的早期COPD 56例,其中男性41例,女性15例;年龄44~76岁,平均年龄(65.8±8.7)岁。纳入标准为:①符合慢性阻塞性肺疾病的诊断标准[8];②处于早期;③均签署知情同意书,并获得本院伦理委员会批准。排除标准为:①肺部肿瘤或肺结核患者;②合并弥漫性支气管炎、闭塞性支气管炎等其它支气管疾病的患者;③胸廓畸形、胸部进行过手术治疗的患者;④有严重的肝肾功能障碍或精神类疾病患者;⑤依从性较差,对该研究不予配合或拒绝接受相应检查的患者。 (雷茂伟 魏雨田)
