Objective To study the clinical pathology and surgical treatment for pulmonary focal GGO byrnaccurate CT positioning. Method 92 patients with pulmonary focal GGO were accepted accurate CT positioningrnbefore surgery. Rational surgical methods were determined according to the imaging characteristics and intraoperativernquick pathological findings. Results Of the 92 surgical patients, 42.4% of them were benign lesions and 57.6% of them were malignancy and premalignant lesions. The proportion of GGO in Pulmonary nodule were < 50% and ≥ 50% , The frequency of occurrence was statistically significant difference (P < 0.01) between benign and malignancy. The proportion of GGO in Pulmonary nodule were <10%、10%~50% and ≥50%, with a statistically significant difference (P < 0.01) in the ratio of lymph nodes metastasis and survival rate at 3 and 5 year. Conclusion We should have a positive attitude in handling focal GGO. A rational surgical methods were determined according to the characteristic of image, the size and proportion of GGO in Pulmonary nodule and intraoperative quick pathological findings to avoid to enlarge the extent of the operation and to delay the reasonable opportunity.%目的:探讨精确CT引导定位局限性肺磨玻璃影(GGO)的临床病理特征和手术合理模式.方法:通过对92例局限性肺GGO术前精准定位,结合影像学特征和术中快速病理结果,选择合理的手术方法.结果:92例手术切除的患者有42.4％为良性病变,57.6％为恶性和癌前病变.肺结节中GGO的比例＜50％和≥50％两组中,比较良性和恶性肿瘤的发生率,有明显的统计学差异(P＜0.01).肺结节中GGO的比例＜10％、10％～ 50％和≥50％三组中淋巴结转移率、3年和5年生存率均有明显的统计学差异(P＜0.01).结论:对于局限性肺GGO我们应持积极主动的态度.手术的切除要结合GGO的比例、结节的大小、快速病理等结果做出合理的判断,避免盲目扩大手术指征和手术范围,又不能延误手术时机,毕竟手术有较高的5年生存率.
