Outline
Lymph node noncompliance is an indicator. If multiple lymph node stations are not detected in each group of lymph nodes submitted for inspection, the specimen is regarded as lymph node noncompliance. Under the background that the incidence of advanced gastric cancer has been increasing year by year, more and more surgeons have begun to pay attention to the surgical effect of radical gastric cancer surgery and the prognostic quality of life of patients. A large number of domestic and foreign experimental studies have shown that the sequence of lymph node metastasis of gastric cancer is roughly from the lesser curvature of the stomach to the lymph nodes around the abdominal aorta. In addition, during the process of lymph node metastasis, there may be lymph nodes that do not appear in the specified location, or due to the factors such as the patient's advanced age, different surgical procedures, thick abdominal fat, deep tumor invasion, and more intraoperative bleeding, the D2 lymph node may be used for gastric cancer. During the resection operation and postoperative pathological sorting, certain errors occurred. Although radical resection of D2 lymph nodes has become a standard surgical approach for the treatment of advanced gastric cancer, a variety of congenital anatomical factors or human error factors will still cause a decrease in the detection rate of postoperative lymph nodes. Therefore, adequate D2 anatomy is still a research focus and difficulty for surgeons. This article discusses the research progress of lymph node noncompliance in D2 radical resection of advanced gastric cancer.
