Abstract
BACKGROUND:Thoracoscopic lobectomy combined with mediastinal lymph node dissection has been considered as one of the standard surgical procedures for early lung cancer. After 20 years of development, thoracoscopic lobectomy has reached a consensus on reliability and minimally invasive. At present, thoracoscopic lobectomy has a variety of incisions, which gradually evolve into four holes based on three holes, and two or one hole as the operative approach. The aim of this study was to evaluate the clinical value of four-hole unilateral dissecting lobectomy and mediastinal lymph node dissection in the treatment of non-small cell lung cancer (NSCLC). The aim of this study was to investigate the clinical value of anatomical lobectomy with mediastinal lymphadenectomy under four-hole completely video-assisted thoracoscopic surgery (C-VATS) in the treatment of non-small cell lung cancer. METHODS: The patients undergoing lobectomy with mediastinal lymphadenectomy for NSCLC were identified in the Department of Thoracic Surgery, Yangzhou First People's Hospital, Yangzhou University from March 2015 to July 2016. Preoperative clinical diagnosis of peripheral-type early NSCLC. The patients were randomly divided into four-hole monophasic group (experimental group) and three-hole group (control group) according to the number of hospitalization before surgery. According to inclusion and exclusion criteria, the 39 cases assign in experimental group and 34 cases in the control group, including 36 males and 37 females; aged 38 to 84 years. The mean operation time, average blood loss, lymph node dissection group, average drainage, average extubation time and postoperative complications were compared between the two groups for statistical analysis. RESULTS: The two groups of patients were successfully completed surgery, no death after surgery. Mean bleeding in the two groups, the number of lymph node dissection group, the average postoperative drainage, the average time of extubation, postoperative complications, with no significant difference. The average operation time of the four-hole unidirectional group was shorter than that of the three-hole group. The difference was statistically significant (P<0.05). CONCLUSIONS: The safety and efficacy of a four-hole one-way operation under VATS are satisfactory. The operation is smooth during operation, which shortens the course of operation and deserves the clinical promotion. .

1994年McKenna等[首次报道胸腔镜肺叶切除加纵隔淋巴结采样治疗早期NSCLC这一术式。经过20余年的发展,全胸腔镜手术的安全性及可行性已被广泛认可,国内外胸外科医生已将这一术式广泛应用于临床。文献[报道了全胸腔镜下治疗早期NSCLC在治疗效果上等甚至优于传统开胸手术的结果。2013年美国国家癌症治疗指南(National Comprehensive Cancer Network, NCCN)则把胸腔镜肺叶切除术作为早期NSCLC的推荐手术方式[。全腔镜下肺叶切除的切口选择多样。国内外胸外科医生可以选择4孔、3孔、2孔甚至单孔作为手术入路[。手术方式上,卜梁等[提出了“王氏”方法,肺裂发育良好可经叶间裂分别处理血管和支气管,如遇到叶间裂分化不全者,先处理肺静脉,再切断支气管,最后分别处理肺动脉各分支,然后将肺叶放回适当位置,沿分裂不全的肺叶裂处用内镜直线缝合切开器将肺叶切除。刘伦旭等[提出了“单向式”法,正对操作孔下行肺叶切除操作,对需切除肺叶在肺门部位软组织内由最表浅的结构开始解剖,依次暴露、离断,只沿一个方向上逐渐深入,最后处理肺裂,不需来回、上下翻转肺叶;切除上、中叶时采取从前向后单方向推进;切除下叶时为从下向上单方向推进。黄佳等[提出了“四孔单向式”法,术中使用“罗氏”器械,器械通过独立的孔道进出,单向操作,治疗效果及安全性满意,同时大大提高手术流畅程度及淋巴结清扫程度。支修益[认为全腔镜下肺叶切除术只是改变了手术入路,而肺癌的外科治疗效果并未因此而改变,应根据各地胸腔镜器械装备的具体情况,手术者技术培训经历和掌握技术的熟练程度,以及地区患者不同的经济承受能力等因素,发展出了各自独具特色的胸腔镜肺叶切除手术方式。我科室全腔镜下肺叶切除术起步较晚,根据自身特点采用传统“三孔”及“四孔单向式”这两种方法。本次研究我们发现两种方式的全腔镜下肺叶切除术,平均术中出血、平均术后引流量、平均拔管时间、术后并发症及平均淋巴结清扫组数并无统计学差异。而平均手术时间有明显统计学差异,四孔单向操作手术时间缩短,过程更加流畅。分析以下因素影响到手术进程。
