D1 Gastrectomy:

Matrics solution D1 gastrectomy involves the removal of the stomach along with a limited number of lymph nodes. During this procedure, the surgeon removes the affected part of the stomach, nearby lymph nodes, and sometimes a small part of the surrounding tissues. However, the lymph nodes removed are limited to those immediately adjacent to the stomach. D1 gastrectomy is typically considered for early-stage stomach cancer cases where the cancer has not spread significantly beyond the stomach.

D2 Gastrectomy:

D2 gastrectomy is a more extensive surgery that involves the removal of the entire stomach along with a more extensive lymph node dissection. During a D2 gastrectomy, the surgeon removes the entire stomach, nearby lymph nodes, and potentially some adjacent tissues or organs that might be affected. The lymph node dissection in a D2 gastrectomy extends further into the lymphatic pathways compared to a D1 gastrectomy. D2 gastrectomy is generally recommended for more advanced cases of stomach cancer or when the cancer has spread to nearby lymph nodes. It is important to note that while D2 gastrectomy may provide a better chance of removing all cancerous tissue and affected lymph nodes, it is a more complex and higher-risk procedure than D1 gastrectomy. The choice between D1 and D2 gastrectomy depends on various factors, including the stage and extent of the cancer, the overall health of the patient, and the expertise of the surgical team. The decision is typically made after a thorough evaluation of each individual case.
