title: [The importance of the mesocolon in the occurrence of liver metastasis from primary colorectal carcinomas].
abstract: The frequency of liver metastasis was analyzed in 1,558 patients with primary colorectal carcinomas. The highest frequency of liver metastasis occurred in carcinomas of the transverse colon (17%) and the sigmoid colon (15%), when compared to the other segments, such as the cecum (10%), ascending colon (9%), descending colon (6%), rectum (9%) and anal canal (0%). It would appear that carcinoma located in those segments of the human colorectum containing any portion of the mesocolon are more prone to metastasize into the liver.
