Abstract:
The concept of radical surgery has experienced from vascular anatomy guidance, lymph node dissection guidance to en-bloc resection guidance. At present, the mesentery guided surgery has developed to a new level of understanding. There are many classical theories on the understanding of the mesentery, from "the mesentery is a wrapped composite structure" to "the mesentery is an organ" and then to "the generalized mesentery theory", but they do not clearly put forward the boundary mark of the mesentery. On the basis of various membrane anatomy theories at home and abroad, we summarized and defined three boundaries of mesenteric excision in radical resection of colorectal cancer. The lateral boundary of the mesentery is the intestinal resection boundary and its mesentery oriented by supplyvessel, the bottom boundary is the mesentery bed, and the central boundary is the degree of lymph node radical resection. Through the detailed description of the mesentery excision, it is helpful to accurately define the mesenteric margin in different stages of radical resection of tumors.
