Standardized lymph node dissection increases the trauma and risk of surgery. Under the tension of doctor-patient relationship, many doctors choose to be conservative to ensure the safety of surgery and lymph nodes are not made standardized. Whether the lymph node dissection is reasonable and standardized can be seen from the postoperative pathology. NCCN requires at least 15 or more lymph nodes to be cleared for radical gastric cancer surgery, but many doctors do not achieve it. In fact, as long as the anatomy is familiar and the sweeping is standardized, it is usually possible to sweep more than 30. Ding Yongbin, Department of Colorectal and Anal Surgery, The First Affiliated Hospital of Nanjing Medical University The five-year survival rate of gastric cancer is about 40% nationwide, but we have done follow-ups on our own patients and the five-year survival rate is 60%, which is much higher than the national level, thanks to our standardized surgery. This is due to our standardized surgery. Moreover, with standardized surgery, patients basically have no complications after surgery.
