Abstract    In the process of personalizing diagnosis and treatment of the colorectal cancer, clinic attention has been increasingly paid on the normalization of surgical operation techniques. In 1982, Professor Heald from the U.K. proposed the procedure of total mesorectal excixon (TME) which contributes a lot to increase the safety of circumferential resection margin and to reduce regional relapse rate. On the basis of research on the anatomic characteristics of mesocolon, Professor Hohenberger from Germany put forward the concept of complete mesocolic excision (CME) in 2009, which provided a significant technical reference for normalizing the dissection of regional lymph nodes of colon cancer. Authors of this article reviewed and interpreted Japanese Standard of Diagnosis and Treatment of Colon Cancer (7th Edition, 2009), trying to explore surgical details of the colorectal cancer both in theory and in practical applications.
