目的 探讨扩大直肠根治在低位直肠癌手术中的临床意义。方法 对46例低位直肠癌侧方淋巴结转移的可能相关因素进行分析。结果 上方淋巴结转移率为54 3%, 侧方淋巴结转移率为19 4%, 侧方淋巴结与癌肿肠壁浸润的深度及分化有关, 统计学处理有显著意义。结论 侧方淋巴结清除特别是在分化差及肿瘤肠壁浸润深的低位直肠癌根治术中有一定的意义, 有助于提高生存率。
Objective To investigate the clinical significance of extended rectal radical operation in low rectal cancer surgery. Methods 46 cases of low rectal cancer patients with lateral lymph node metastasis may be related factors. Results The rate of lymph node metastasis was 54.3% and the rate of lateral lymph node metastasis was 19.4%. The depth and differentiation of side lymph nodes were related to the infiltration of colorectal wall. Statistical analysis was significant. Conclusions Lateral lymph node dissection is of particular significance in the treatment of low rectal cancer with poor differentiation and deep invasion of the intestinal wall, which is helpful to improve the survival rate.
