Surgery is an effective method in the treatment of stomach cancer. In the early stages of the disease, gastric lymph node dissection and laparoscopic surgery are often used. For advanced gastric cancer cases, laparoscopic gastric bypass surgery is also commonly used.
1. What is D2 lymphadenectomy?
Previously, open gastrectomy was the only method of treatment for gastric cancer. The disadvantages of this method are a lot of damage, loss of blood, pain, and a long recovery time. With the development of modern medicine, less invasive laparoscopic surgery is more and more developed and widely used.
In patients with early gastric cancer, patients have low risk of lymph node metastasis, so endoscopic gastrointestinal surgery is the first choice, especially in Japan and Korea. Although the long-term oncological results of this method are still being studied, laparoscopic surgery for early gastric cancer is being used very popularly around the world.
Besides, many countries also have a view of widespread lymphadenectomy in gastric cancer with the technical term of D2 lymphadenectomy. Means gastrectomy and removal of lymph node groups in stage 1 (R1) and stage 2 (R2). In some cases, an enlarged D2 lymph node dissection may be necessary, i.e. removal of an additional part of the node at stage 3 (R3).
