Postoperative lymphatic leakage will not be cured by itself. Generally, after surgical treatment of tumors, such as neck thyroid surgery or surgery for stomach cancer, breast cancer, kidney cancer, etc., in order to completely remove latent cancer cells, the adjacent lymph will be cleared, which will easily trigger lymphatic leakage from local tissues after the surgery, leading to the discharge of clear or celiac-like fluid from the drainage tube with significantly increased volume. Should communicate with the doctor in time, after clear diagnosis, take corresponding measures for systematic treatment. If not treated in time, a large number of lymphocytes, body fluids and nutrients will be lost due to lymphatic leakage, resulting in electrolyte imbalance and slow recovery of the patient, etc. If the drainage is not smooth, the lymphatic fluid will form an accumulation of fluid in the subcutaneous area, and there will be local pain, redness and swelling, and in severe cases, it will also stimulate the muscles, nerves, and blood vessels around the leakage point It may also cause severe irritation to the muscles, nerves and blood vessels around the leakage point, leading to local infection and other more serious consequences. It is recommended to closely observe the drainage situation after the surgery, communicate with the doctor if there is any abnormality, and take appropriate means to find and treat the leakage point in time after the possibility of lymphatic leakage occurs.
