总结应用0°镜头的单孔胸腔镜肺癌根治术的操作经验及患者临床资料，探索0°镜头的优、缺点。

回顾性分析分别来自北京协和医院和澳门仁伯爵综合医院的35例肺癌患者(包含1例转移癌)经0°镜头下单孔胸腔镜肺癌根治术(包括肺叶/全肺切除＋纵隔淋巴结清扫)的临床数据。其中男性22例、女性13例，年龄(63.11 ± 9.89)岁。

34例手术成功完成、1例中转开胸，患者均顺利出院。统计修正后，手术时间(218.59 ± 36.80)min，术中出血量(177.27 ± 94.62) ml，淋巴结清扫数(19.03 ± 6.39)枚，术后带管时间(5.74 ± 4.34)d，术后住院时间(5.97 ± 1.85)d。5例患者出现术后并发症，占全组病例14.3%。

对比国外相关文献，本队列患者的手术时间、术中出血量、术后并发症发生率接近，淋巴结清扫数稍高，证明了0°镜头下单孔胸腔镜肺癌根治术的可行性与安全性。0°镜头可能在单孔胸腔镜术中存在潜在优势。

To summarize the patients` clinical data and the experience of the 0-degree lens application into the uniportal video assisted thoracoscopic surgery (VATS) of radical resection of lung cancer and discuss its strengths and weaknesses.

Clinical data and surgical outcome of 35 lung cancer patients [22 male and 13 female, a mean age of (63.11 ± 9.89 ) years] from Peking Union Medical College Hospital and Centro Hospitalar Conde De S. Januá rio, who underwent the uniportal VATS radical resection of lung cancer, including lobectomy/pneumonectomy and systemic mediastinal lymph nodes dissection, were collected from their clinical files.

34 patients′ operations were successfully performed under uniportal VATS and 1 patient needed thoracotomy. The mean operation time is( 218.59 ± 36.80) minutes and the mean blood loss is( 177.27 ± 94.62 )ml. The mean number of retrieved lymph nodes is (19.03 ± 6.39). The mean chest tube duration is (5.74 ± 4.34) days and the mean postoperative hospital stay is (5.97 ± 1.85) days. 5 patients had postoperative complications, 14.3% of all patients. All the patients were discharged in good health.

Comparing with the researches published by foreign thoracic surgeons, the operating time, blood loss, and postoperative complication rate of this cohort have no significant difference and the number of retrieved lymph nodes is higher. Therefore, this study proved the feasibility and safety of uniportal VATS for lung cancer under 0-degree lens and its potential advantage.
