Surgical treatment for colon cancer patients requires resection of a certain length of intestinal tubes according to the condition. In order to ensure complete resection and reduce the risk of recurrence, radical surgery requires resection of intestinal tubes more than 10 centimeters proximal and distal to the tumor, which cannot be regenerated after the resection, and reconstruction of intestinal tract is needed. For example, transverse colon cancer requires resection of the entire transverse colon including the hepatic flexure to the splenic flexure of the colon, followed by anastomosis of the ascending and descending colon. The normal adult colon is about 1.5 meters long and has a strong compensatory capacity, so even if a part of the colon is removed, the remaining part can maintain normal absorption and metabolism, so patients do not need to worry too much. Even if there is some absorption disorder, it can be improved by adjusting diet or lifestyle habits. Most patients with partial removal of the colon can maintain a normal life. Radical surgical resection is the most effective treatment for colon cancer, and early stage patients are expected to achieve curative effect. Therefore, for patients who are eligible for surgery, it is recommended to have surgery as early as possible, so as not to delay the treatment due to excessive worry about the adverse effects of intestinal resection.
