Extent of lymph node dissection and interpretation of technical standards for 4K laparoscopic distal gastrectomy in gastric cancer / 中华消化外科杂志

ABSTRACT

Radical resection is still the main method to cure gastric cancer. Lymph node metastasis is a common metas-tatic pattern of gastric cancer. The risk of local lymph node invasion increases with the tumor invasion depth of gastric wall. Standard lymph node dissection is an important step to improve the prognosis of patients with gastric cancer. At present, D 2 radical gastrectomy is the standard procedure for locally advanced gastric cancer. Therefore, it is of great significance to popularize the standardization of lymph node dissection in radical gastrectomy on the basis of 4K laparoscopic platform, which can improve the treatment level of gastric cancer surgeons and provide "homogenized" diagnosis and treatment services for patients.
