Lymph node excision, also known as lymphadenectomy or lymph node dissection, is a surgical procedure that involves the removal of one or more lymph nodes from the body. Lymph nodes are small, bean-shaped organs that are part of the lymphatic system, which plays a crucial role in the body's immune response.
Lymph node excision is commonly performed in the diagnosis and treatment of various medical conditions. It may be done to examine the lymph nodes for signs of cancer metastasis or infection, as well as to remove cancerous or abnormal lymph nodes. The procedure is often a part of the treatment plan for cancers that have spread to the lymph nodes, such as breast cancer, melanoma, or head and neck cancers.
During the procedure, an incision is made in the affected area, and the surgeon carefully identifies and removes the lymph nodes. The number of nodes removed depends on the specific medical condition and its stage. The removed lymph nodes are then examined under a microscope to determine the presence of abnormal cells.
Lymph node excision can have certain risks and complications, such as infection, bleeding, or damage to nearby structures. However, it is generally a safe procedure when performed by experienced surgeons.
Overall, lymph node excision is an important surgical procedure used for diagnosis, staging, and treatment of various medical conditions, particularly cancer. It plays a crucial role in improving patient outcomes by helping to guide further treatment decisions and providing valuable information about the spread and severity of disease.
