Research progress in colon cancer surgery

Colon cancer is one of the top three malignant tumors in the world, in recent years, the incidence and mortality of this disease are increasing, which seriously threatens human life and health. At present, surgery is still the main treatment for colon cancer, combined with chemotherapy and other measures can effectively improve the survival of patients. Different surgical methods have different prognostic effects on patients. In terms of intraoperative lymph node dissection for colon cancer, lymph node dissection during total mesocolic resection and D3 radical resection has significantly improved prognosis for colon cancer. Lymph node metastasis of colon cancer is common, with the presence of skip metastasis, lymph node dissection is important for the prognosis of patients, tumor recurrence and tumor metastasis. Therefore, it is necessary to make clear the diagnosis and lymph node metastasis before surgery, determine the surgical procedure and the scope of lymph node dissection, so as to avoid postoperative complications caused by inadequate tumor recurrence or excessive clearance.
