Although stomach cancer surgery can be done in many areas, but remind everyone ！！！！！！ Since you have cancer and have to have surgery, why don’t you achieve radical cure? Don’t let the haphazard treatment delay the disease! Siping Central Hospital Oncology Surgery Department Wang Jianqiang Our department is the only one in the surrounding areas that can perform radical treatment! The strong and solid surgical foundation of our director can’t be compared with any hospital or individual in the surrounding area! This people can ask the surgeon about the strength of the director! Surgical operation is the only way to cure gastric cancer, and perigastric lymph node dissection is the key point and difficult point in gastric surgery. Through long-term clinical practice, the surgical method of radical gastric cancer surgery has gradually become unified, that is, while the diseased organ is fully removed, its corresponding metastatic lymph nodes and the adjacent organs infiltrated should be removed. The scope of lymph node removal is still controversial. Some scholars in western countries believe that a major gastrectomy (D1 radical surgery), which mainly removes the paragastric lymph nodes, is sufficient, while scholars in East Asian countries such as Japan, China and Korea have adopted D2 lymph node dissection as the standard radical surgery for gastric cancer. D1 radical surgery for gastric cancer is to remove most of the lymph nodes at station 1 along with the focal stomach, which is actually equivalent to the traditional resection of most of the stomach and omentectomy, and then to remove the enlarged lymph nodes visible to the naked eye. The principles of D2 lymph node dissection are as follows: 1) the lymph nodes and fatty tissues visible to the naked eye are removed along with the whole lesion, which is the most ideal way; 2) the lymph nodes and fatty tissues visible to the naked eye are removed along with the whole lesion. 2. some lymph nodes are closely related to blood vessels, so the surrounding lymph nodes, fat and nerve fibers should be removed together without cutting off the blood vessels. Standard D2 radical surgery for gastric cancer plays an important role in the surgical treatment of gastric cancer in Asia, including our country. Under the current situation that progressive gastric cancer is the majority in China, D2 radical surgery for gastric cancer is still considered as the standard radical treatment for gastric cancer. Standard D2 radical surgery for gastric cancer has been carried out in some hospitals in China, and many large medical centers have accumulated rich experience in standard D2 radical surgery for gastric cancer. However, the promotion is very uneven, and many primary hospitals still use the surgical approach of the 1960s and 1970s, i.e. resection of the diseased stomach, large omentum and enlarged lymph nodes as the D2 radical surgery for gastric cancer. In the past, the efficacy of gastric cancer in China was poor, the surgical resection rate was low, and the 5-year survival rate of patients after surgery was only about 20%. Since 1987, when we started to carry out standard gastric cancer D2 radical surgery, there has been a breakthrough in the efficacy of gastric cancer surgery in China, and the 5-year survival rate has increased to 57.6%. At present, the aim of gastric cancer surgery is to remove the primary tumor and metastases to achieve A-level radical treatment, i.e., the lymph node dissection range exceeds the range of existing lymph node metastases, so that no cancer remains. The biological behavior of gastric cancer is characterized by infiltrative growth and metastatic pathways mainly through the lymphatic system, and D2 radical surgery for gastric cancer is designed and formulated to meet these characteristics. Therefore, D2 radical surgery for gastric cancer is regarded as the standard procedure for progressive gastric cancer in today’s medical field. The biggest advantage of D2 radical surgery is that it completely eliminates the main cause of metastasis recurrence, i.e., the lymph nodes at stations 1 and 2, thus greatly improving the surgical efficacy. In terms of preventing postoperative metastatic recurrence, D2 shows significant superiority over D1. In terms of improving postoperative survival rate, the recent efficacy of D2 radical surgery also shows obvious advantages. Our department is mainly dedicated to the research on the prevention and treatment of gastrointestinal tumors, mainly gastric cancer, and the promotion of standardized comprehensive treatment of malignant tumors. With the increase in the number of patients treated, we have summed up a set of successful experiences and implemented a standardized comprehensive treatment plan based on standard D2 radical resection and radical surgery for other tumors, with a 5-year survival rate of 60% for radical resection, which is among the most advanced in China.
