近年来大肠癌的发病率逐年增加,而远期治疗效果仍难令人满意。究其原因主要是淋巴转移癌的残留及局部切除的不彻底所造成的复发和远处转移。因此,研究大肠癌淋巴转移规律,确定合理的淋巴清除范围,对减少复发,提高生存率意义重大。为此,我们从形态学角度对国人大肠癌淋巴转移规律进行了研究,进而确定了合理的淋巴结清除范围,指导了临床手术治疗。一、大肠癌淋巴转移的解剖学基础国内外一些解剖学家研究认为,结肠的集合淋巴管多注入位于结肠壁与结肠动脉弓之间的肠旁淋巴结,也可先注入位于结肠浆
In recent years, the incidence of colorectal cancer has increased year by year, and the long-term therapeutic effect is still unsatisfactory. The main reasons for this are the recurrence and distant metastasis caused by residual lymphatic metastasis and incomplete removal of local resection. Therefore, to study the rule of lymphatic metastasis of colorectal cancer and determine the reasonable range of lymphatic clearance is significant for reducing recurrence and improving survival rate. To this end, we studied the lymphatic metastasis of colorectal cancer in China from the perspective of morphology, and then determined a reasonable range of lymph node clearance, and guided the clinical surgical treatment. First, the anatomical basis of lymphatic metastasis of colorectal cancer Some domestic and international anatomists have studied that the colon’s collecting lymphatic vessels inject more of the para-intestinal lymph nodes located between the colon wall and the colonic artery arch, and can also be injected into the colonic cytoplasm.
