孤立性肺小结节CT诊治的临床回顾研究

目的探讨孤立性肺小结节高分辨率C T诊断及临床治疗方法的相关性。方法回顾性分析2011年1月—2013年8月我院50例孤立性肺小结节患者的64排螺旋C T诊断结果及临床治疗情况。结果对于直径为≤1 cm、1 cm～2 cm及2 cm～3 cm的结节64排螺旋C T诊断敏感性分别为90.01%,97.35%及100%;特异性分别为50.25%,70.45%及80%。其中≤1cm的结节恶性率为35.1%,1 cm～2 cm结节恶性率为52.3%,2 cm～3 cm结节恶性率为76.5%。孤立性肺小结节的C T诊断及治疗因其大小及性质而存在明显差异。结论≤2 cm的孤立性肺小结节C T不能明确为良性时应行胸腔镜手术切除,2 cm～3 cm的肺孤立性小结节可先行穿刺活检明确病灶性质,恶性结节则行胸腔镜手术切除。

Clinical study of the diagnosis and treatment of small solitary pulmonary nodules

Objective To summarize the correlation of the solitary pulmonary nodule between the high resolution CTdiagnosis and clinical treatment. Methods A retrospective study about50 cases smallsolitary pulmonary nodules in 64 slice spiral CT diagnosis and clinical data. Results For diameter ≤1 cm,1 cm～2 cm and 2 cm～3 cm nodules in 64 slice spiral CT diagnostic sensitivity was 90.01%,97.35% and 100%;specificity were 50.25%,70.45%and 80%. The nodule of diameter ≤ 1cm malignant rate was 35.1%,1 cm～2 cm nodules malignant rate was 52.3% by surgical removal of the pathological diagnosis,2 cm～3 cm nodule malignant rate was 76.5% with biopsy in the diagnosis of specificity of 97.37%. The CT diagnosis of pulmonary nodules had obvious difference in its size and properties.Conclusion ≤2 cm nodules should be underwent thoracoscope surgery,2 cm～3 cm nodules should first clear nature of the lesion biopsy and then malignan tnodules should resect by thoracoscope surgery.
