We have read with great interest the work published by Bernhoff et al. [1]. The authors evaluate long-term oncological outcomes of complete mesocolic excision (CME) surgery for right colon cancer in a population-based cohort study. The authors developed predefined criteria of CME surgery: (1) dissection of the mesocolon from the duodenum and the head of the pancreas; (2) visualization of the superior mesenteric vein (SMV); (3) ligation of the ileocolic vessels at the level of the SMV; (4) ligation of the right branch of the middle colic vessels at its origin or central ligation of the middle colic vessels; (5) integrity of the mesocolon and the resected bowel segment. The authors achieved significantly better results in terms of cancer-specific mortality after right hemicolectomy for colon cancer by employing predefined CME features, and we were inspired to in a further comment in this fascinating and challenging context.

需要定义正确的结肠系膜切除术和完整的结肠系膜切除术 (CME) 概念：如何、何时以及为什么？

我们饶有兴趣地阅读了 Bernhoff 等人发表的著作。[1]。作者在一项基于人群的队列研究中评估了右结肠癌完全系膜切除 (CME) 手术的长期肿瘤学结果。作者制定了 CME 手术的预定义标准：（1）从十二指肠和胰头分离结肠系膜；(2) 肠系膜上静脉 (SMV) 的可视化；(3) 在 SMV 水平结扎回结肠血管；(4)中绞痛血管右支原处结扎或中绞血管中央结扎；(5) 结肠系膜和切除肠段的完整性。作者通过使用预定义的 CME 特征，在结肠癌右半结肠切除术后癌症特异性死亡率方面取得了显着更好的结果，
