目的探讨左、右半结肠癌淋巴结转移方式上的差异。方法结肠癌患者118例,其中行D2式淋巴廓清术者12例,D3式90例,D4式16例。用新鲜标本挤压触诊法行淋巴结检取。统计N1,N2,N3,N4站淋巴结的转移情况。结果左半结肠癌淋巴结转移率为33.8%,其中肠旁淋巴结转移率为28.0%,中枢方向淋巴结转移率为19.1%。右半结肠癌的淋巴结转移率为52.0%,其中肠旁淋巴结转移率为52.0%,中枢方向淋巴结转移率为38.0%。结论右半结肠癌肠旁淋巴结及中枢方向淋巴结的转移率均高于左半结肠癌。结肠癌的手术应以D3术式为基本术式,重点要清扫向中枢方向转移的淋巴结。
Objective To investigate the differences of lymph node metastasis in left and right colon cancer. Methods 118 cases of colon cancer patients, including D2 lymphadenectomy in 12 cases, D3 90 cases, D4 16 cases. With fresh specimens squeeze palpation line lymph node retrieval. Statistical N1, N2, N3, N4 lymph node metastasis. Results The rate of lymph node metastasis in the left colon cancer was 33.8%. The rate of lymph node metastasis in the left colorectal cancer was 28.0% and the rate of lymph node metastasis in the central area was 19.1%. The right-sided colon cancer had a lymph node metastasis rate of 52.0%, of which the intestinal lymph node metastasis rate was 52.0% and the central lymph node metastasis rate was 38.0%. Conclusions The metastatic rates of the right and left colon colon stromal lymph nodes and central lymph nodes are higher than those of the left colon carcinoma. Colon cancer surgery should be based on the D3 technique as the basic surgical procedures, focusing on the removal of lymph nodes metastasis to the central direction.
