To define the anatomy of the mesocolic attachment of the colon as seen on computed tomographic (CT) scans, the authors reviewed CT scans of patients with diseases of the colon and the pancreas and found that disease processes in these areas usually spread along the mesocolon. The plane of the mesocolon can be distinguished from the mesentery of the small bowel by identifying the vessels in the mesocolon that serve as its landmarks. These vessels include the ileocolic vessels and right colic vessels for the ascending mesocolon, the middle colic vessels for the transverse mesocolon, and the inferior mesenteric vein for the sigmoid and descending mesocolon. These vessels can be seen routinely on CT scans of the abdomen and pelvis, and knowledge of the anatomy of the mesocolon can help the radiologist understand and identify the pathways for spread of diseases of the colon and pancreas. Recognition of the anatomy of the mesocolon is also helpful in the identification of the pattern of recurrent disease after treatment.
为了明确在计算机断层扫描（CT）上所见的结肠系膜附着部的解剖结构，作者回顾了患有结肠和胰腺疾病患者的CT扫描图像，发现这些区域的疾病进程通常沿系膜扩散。通过识别作为其标志的结肠系膜内的血管，可以将结肠系膜平面与小肠系膜区分开来。这些血管包括升结肠系膜的回结肠血管和右结肠血管、横结肠系膜的中结肠血管以及乙状结肠和降结肠系膜的肠系膜下静脉。这些血管在腹部和骨盆的CT扫描中通常可见，了解结肠系膜的解剖结构有助于放射科医生理解和识别结肠和胰腺疾病的扩散途径。认识结肠系膜的解剖结构对于识别治疗后疾病复发的模式也有帮助。
