目的 探讨食管癌右颈气管旁三角区内淋巴结的转移规律及其清扫方法。方法 在胸腹二野淋巴结清扫的基础上 ,采用经右胸打开右胸顶胸膜 ,显露右颈气管旁三角进行该区域淋巴结清扫。对不同区域淋巴结进行分组编号及病理检查。结果 333例食管癌患者右颈气管旁三角区内淋巴结转移率为 36 .0 4 % ,转移度为 2 4 .96 % ;颈段食管癌右颈气管旁三角区淋巴结转移率为 6 6 .6 7% ,转移度为 4 4 .4 4 % ;上段食管癌右颈气管旁三角区淋巴结转移率为 4 5 .4 5 % ,转移度为 2 7.0 4 % ;中段食管癌右颈气管旁三角区淋巴结转移率为 34.19% ,转移度为 2 4 .32 % ;下段食管癌右颈气管旁三角区淋巴结转移率为 15 .79% ,转移度为 18.92 % ;转移率之间差异有显著性 (P <0 .0 5 ) ,转移度之间差异无显著性 (P >0 .0 5 )。PTis、PT1、PT2、PT3、PT4期右颈气管旁三角区淋巴结转移率分别为 0、17.2 4 %、2 8.70 %、4 5 .16 %和 5 3.5 7% ,转移度分别为 0、8.77%、17.6 2 %、33.0 0 %和 4 1.17% ,各期转移率及转移度之间差异有非常显著性 (P <0 .0 1)。乳头型早期食管癌的右颈气管旁三角区淋巴结转移率为4 0 .0 0 % ,转移度为 2 3.5 3% ;糜烂型转移率为 3.85 % ,转移度为 1.82 % ;斑块型和隐伏型转移率和转移度均为 0 ;四者转移
Objective To investigate the rule of lymph node metastasis in the right trochanter of esophageal squamous cell carcinoma and the method of its dissection. Methods On the basis of lymphadenectomy of the chest and abdomen, the right chest pleura was opened through the right thoracic cavity and the right trochanter was revealed to perform lymph node dissection in this area. Different regional lymph node grouping number and pathological examination. Results 333 cases of esophageal cancer in patients with right trochanteric regional lymph node metastasis rate was 36.0%, the degree of transfer was 24.66%; cervical segment of the right subarachnoid bronchial lymph node metastasis rate of 66.6 7%, the degree of metastasis was 44.44%; the upper right esophageal carcinoma of the right triangular trachea triangular lymph node metastasis rate was 45.54%, the transfer rate was 2 7.04%; the middle right esophageal right tracheal triangle area The rate of lymph node metastasis was 34.19% and the degree of metastasis was 24.32%. The rate of lymph node metastasis was 15.79% and the degree of metastasis was 18.92% in the lower right esophageal right tracheal triangle. The difference was significant <0. 05), there was no significant difference in the degree of metastasis (P> 0.05). The rates of lymph node metastasis in the right trochanteric triangle of PTis, PT1, PT2, PT3 and PT4 were 0,17.2 4%, 2 8.70%, 45.6% and 53.5%, respectively, and the degrees of metastasis were 0, 8.77% , 17.6%, 33.0%, and 41.17%, respectively. There was a significant difference between the rates of metastasis and metastasis (P <0.01). The rate of lymph node metastasis in the right trochanteric triangle of papillary early esophageal carcinoma was 40.0%, the degree of metastasis was 23.5%, the rate of erosive metastasis was 3.85% and the degree of metastasis was 1.82% Type transfer rate and transfer degree are 0; four transfer
