[Brief discussion on prevention of the secondary damage in the procedures of D2 lymphadenectomy for gastric cancer].

So far, D2 lymphadenectomy has been recognized as the key one of the procedures in curative resection for gastric cancer. In summary, the standardized implementation of D2 lymphadenectomy can contribute to both surgical quality and patients' prognosis. Lymph node dissection, as an important basis for local surgical treatment of gastric cancer, involves certain technical risks due to complex adjacent relationship and anatomical variation of organs or blood vessels, and so on. There is a certain incidence of side injuries in D2 lymphadenectomy for a surgeon, regardless of the experience of learning curve. Complying with specification of surgical procedures and summarizing the vital points of lymph node dissection in each curative gastrectomy for gastric cancer is the principal method to reduce or avoid the occurrence of relevant complications after surgery.
