Colorectal carcinoma is a common malignant tumor which shows a standard behavior for lymphogenic metastasis. Depending on the localization of the primary tumor the corresponding lymphatic area also has to be removed because lymph node metastases can already be present by every tumor even if there is no obvious intraoperative evidence. Lymphatic drainage is essentially oriented to the supplying arteries of the corresponding intestinal segment. The anatomy of arterial supply is individually variable and often deviates from the usual textbook presentation. In this review the oncological requirements of an adequate lymph node dissection in colorectal carcinoma are described with emphasis on the technical aspects to obtain an optimal specimen.
结直肠癌是一种常见的恶性肿瘤，具有典型的淋巴转移行为。根据原发肿瘤的位置，相应的淋巴区域也必须切除，因为即使术中没有明显证据，每个肿瘤都可能已经存在淋巴结转移。淋巴引流主要朝向相应肠段的供应动脉。动脉供应的解剖结构个体差异较大，常常与教科书上的常规描述不同。在本综述中，描述了结直肠癌充分淋巴结清扫的肿瘤学要求，重点强调获取最佳标本的技术方面。
