胸腔镜手术与开胸手术在胸段食管癌患者淋巴结清扫中的对比

Comparison of thoracoscopic surgery and open surgery in thoracic esophageal cancer patients with lymph node dissection

目的探讨胸腔镜手术与开胸手术下胸段食管癌患者的淋巴结清扫状况。方法选取2012年8月-2015年6月在该院接受胸腔镜手术治疗的胸段食管癌患者16例(微创组),选取同期经传统开胸手术的相同病理分期的胸段食管癌患者17例(传统组),比较两组患者清扫淋巴结数、阳性率及淋巴结转移情况。结果微创组16例,清扫淋巴结总数228枚,均数(14.27±5.61)枚,阳性率为12.50%;传统组17例,清扫淋巴结总数241枚,均数(16.20±6.24)枚,阳性率为11.76%。两组不同病理分期患者淋巴结清扫数差异无统计学意义(P>0.05)。微创组转移淋巴结例数7例,转移淋巴结45枚,转移率为43.75%,转移度为19.74%;传统组转移淋巴结例数8例,转移淋巴结55枚,转移率为47.06%,转移度为22.82%。结论微创手术能够取得与传统开胸手术一致的淋巴结清扫效果,在胸段食管癌的临床治疗方面具有较高可操作性。

Objective To explore the status of lymph node dissection under thoracoscopic surgery and open surgery in patients with thoracic esophageal carcinoma. Methods 16 cases of thoracic esophageal cancer received thoracoscopic surgery from August 2012 to June 2015 as minimally invasive group （group M）, 17 cases of thoracic esophageal cancer with the same pathological staging received traditional open surgery during the same period as control group （group C）, the number of lymph nodes and the positive rate of lymph node metastasis were compared. Results In group M, the total number of 228 lymph nodes, mean （14.27 ＋_ 5.61） pieces, the positive rate was 12.50%; while in group C, the total number of 241 lymph nodes, mean （16.20 ＋ 6.24） pieces, the positive rate was 11.76 %. Two different pathological staging in patients with lymph nodes dissection has no significant difference （P 〉 0.05）. In group M, 7 cases with lymph node metastasis, 45 metastatic lymph nodes, metastasis rate was 43.75 %, 19.74 % degree of metastasis; while in group C, 8 cases with lymph node metastasis, 55 metastatic lymph nodes, metastasis rate was 47.06%, transfer degree was 22.82%.Conclusions Minimally invasive surgery can achieve the same effect with the traditional open chest surgery, in treatment of thoracic esophageal cancer with high operability.
