Abstract: 【Abstract】〓Objective〓To summarize the diagnostic and therapic experence of video-assisted thoracoscopic surgery for subcentimeter pulmonary nodules. Methods〓Thirty-eight patients with subcent-imeter pulmonary nodules highly suggested of a malignancy by CT scan were retrospectively analyzed. Perioperative period data about hookwire location and video-assisted thoracoscopic surgery was summarized..Pathological results of the subcentimeter pulmonary nodules was analyzed. Results〓All lesions were successfully identified by the hookwire approach..All the operations were completed with no serious complication,.including wedge resection in 24 cases, segmentectomy in 4 and lobectomy with lymph node dissection in 10..Pathological diagnosis identified 15 invasive carcinomas,.5 pre-invasive carcinomas, 2 metastatic tumors and 16 benign lesions..The pathological coincidence rate between frozen section and paraffin section was 92.1%..Conclusion〓Subcentimeter pulmonary nodules are difficultly diagnosed in preoperative and intranperative period..Video-assisted thoracoscopic surgery is one of the effective and safe techniques for the diagnosis and therapy of subcentimeter pulmonary nodules.

摘要： 【摘要】〓目的〓总结全胸腔镜手术对肺部亚厘米结节的诊治经验。方法〓对一组CT诊断怀疑为恶性的肺部孤立性结节病例(38例)进行回顾性分析,总结Hookwire定位、胸腔镜手术的围术期资料,并对亚厘米结节的病理结果作一总结分析。结果〓所有结节借助Hookwire能明确定位,无严重并发症;全组均顺利完成手术,包括楔形切除术24例,肺段切除术4例,肺叶切除及淋巴结清扫术10例。中转开胸2例,无围术期死亡,术后均获得明确诊断;其中浸润性癌15例,浸润前病变5例,转移瘤2例,良性病变16例。冰冻病理与石蜡病理的符合率为92.1%。结论〓采用全胸腔镜手术对肺部亚厘米结节的进行术前检查是一项安全、有效的诊断或治疗手段。
