胸腔镜辅助小切口手术诊治肺周围型结节

目的探讨胸腔镜辅助小切口手术在诊断和治疗肺周围型结节病变中的临床应用价值。方法胸腔镜辅助小切口手术诊治肺周围型结节55例，其中单发结节54例，多发结节1例。肺楔形切除术23例；肺叶切除联合淋巴结清扫治疗原发性肺癌32例，采用常规开胸手术器械及胸腔镜用器械切除肺叶，自制淋巴结摘除钳完成淋巴结清扫。结果55例均在胸腔镜下完成手术。手术时间35～180min，平均109min，术中出血量50～400ml，平均122min。均未输血，1例术后漏气术后32d出院，1例切口延迟愈合，术后19d出院，余53例术后住院4～11d，平均8．3d。无严重并发症。术后病理：良性病变15例，原发性肺癌38例，非典型性腺瘤样增生1例，转移性肺癌1例。良性病变行肺楔形切除术，32例原发性肺癌行解剖学肺叶切除联合淋巴结清扫，4例肺癌胸膜广泛播散未手术处理，2例肺癌因肺功能差行姑息性肺楔形切除。结论胸腔镜辅助小切口手术有助于明确诊断肺周围型结节病变，治疗临床早期原发性肺癌的长期疗效有待随访观察。

Application of video-assisted mini-thoracectomy for the diagnosis and treatment of peripheral pulmonary nodules

Objective To evaluate the reliability of video-assisted mini-thoracectomy(VAMT) for the diagnosis and treatment of patients with pulmonary peripheral nodules.Methods A total of 55 patients with pulmonary peripheral nodules(1 case of multiple nodules and 54 cases of solitary nodule) underwent VAMT.The surgery included wedge resection in 23 patients and lobectomy with lymph node dissection in 32 patients(The lobectomy was performed by using conventional combined with thoracoscopic instruments.A self-made lymph node clamp was applied for lymph node dissection).Results The operation was successfully accomplished under thoracoscopy in all the 55 patients.The operation time was 35~180 min(mean,109 min) and the intraoperative blood loss was 50~400 ml(mean,122 ml).No blood transfusion was required.Postoperative complications included air leakage in 1 patient(discharge on the 32 postoperative day) and delayed wound healing in 1 patient(discharge on the 19 postoperative day).The length of postoperative hospital stay of the other 53 patients was 4~11 days(mean,8.3 days).Final pathological diagnosis showed 15 cases of benign lesions,38 cases of primary lung carcinoma,1 case of atypical adenomatous hyperplasia,and 1 case of metastatic lung cancer.The benign lesions were cured by wedge resection.Anatomic lobectomy with lymph node dissection was performed in 32 patients with primary lung cancer.Of other 6 patients with terminal lung cancer,4 patients were conservatively treated because of an extensive dissemination and 2 patients received a palliative wedge resection because of poor pulmonary functions.Conclusions Video-assisted mini-thoracectomy is helpful for the diagnosis and treatment of pulmonary peripheral nodules.Its long-term effects for clinical early-stage lung cancer need further follow-up investigations.
