胸腔镜下行食管癌切除术对胸部淋巴结清扫的影响

目的　探讨电视胸腔镜下行食管癌切除胸部淋巴结清扫术的安全性和可行性，以及对淋巴结清扫的彻底性和生存率的影响。方法　以电视胸腔镜下行食管癌切除胸部淋巴结清扫术26例为观察组 ,同期行常规开胸食管癌切除淋巴结清扫术28例为对照组， 比较两组手术情况，胸部淋巴结清扫情况和近期疗效.。结果　两组均顺利完成手术，观察组和对照组在胸部各部位淋巴结的清扫数目，转移率，转移度，术后一年生存率的差异均无统计学意义（P>0.05）。结论　电视胸腔镜下行食管癌切除、胸部淋巴结清扫手术是安全可行的，可达到常规开胸手术相同的效果。

Study on lymph node dissection for esophageal cancer by video assisted mini- thoractomy

Objective To discuss the safety, effect and radical resection of lymph node dissections by VAMT for patients with esophagus carcinoma. Methods 26 patients with esophagus carcinoma received esophagectomy and systemic lymph node dissection by VAMT, 28 cases underwent routine open thoracotomy as controls in the same time. The data of lymph node resection, perioperative clinical results and 1-year survival in each group were compared. Result The surgeries were successful performed. No significant difference was found in total numbers, positive rates, metastasis ratio of dissected lymph nodes and 1-year survival rates between two groups(p>0.05).Conclusion Systemic lymph node dissection can be safely and effectively conducted by VAMT for resection of esophagus carcinoma.
