目的：掌握回结肠肠段的静脉配布及其特点，以指导回结肠代食管术的实施。方法：大体解剖观察５０例尸体回盲部、升结肠、横结肠的静脉配布及边缘吻合。结果：①静脉配布较恒定；②右结肠静脉主干短，多数呈多属支状，属支间于结肠缘吻合少；③右结肠静脉与中结肠静脉间３例边缘吻合中断。结论：右结肠静脉的结扎必须在主干进行。
OBJECTIVE: To master the distribution of veins and its characteristics in the colon and intestine, in order to guide the implementation of colon esophageal surgery. Methods: Fifty cases of ileocecal cadaveric herniation, ascending colon, transverse colon vein distribution and edge anastomosis were observed. Results: (1) The distribution of veins was relatively constant; (2) The trunk of the right colonic vein was short and most of the branches were mostly branch-shaped with less anastomosis between the branches of the colon; (3) the marginal anastomosis between the right colonic vein and the middle colonic vein was interrupted. Conclusion: Ligation of the right colon vein must be performed in the trunk.
