Symptoms of lymphatic fistula

The clinical symptoms of lymphatic fistula generally include fluid discharge, poor wound healing, and chyluria.

1. Fluid Discharge

Lymphatic fistula often occurs after lymph node dissection or biopsy surgery. Due to injury, failure to ligate, or incomplete ligation of lymphatic ducts, or as a result of infection, patients may experience recurrent exudation, typically clear lymphatic fluid. Under medical guidance, packing can be used to prevent continued fluid leakage.

2. Poor Wound Healing

In most cases, leaked lymphatic fluid accumulates at the wound site. If not promptly cleaned, this can easily lead to impaired wound healing, abscess formation, or fluid discharge upon pressure. After surgery, clean gauze can be applied with gentle pressure on the wound to promote healing. A balanced diet rich in protein, such as eggs and milk, should also be maintained in daily life.

3. Chyluria

If lymphatic leakage is severe, it can affect urine, leading to chyluria—urine that appears milky white, with or without renal colic. Currently, treatment for chyluria involves injecting sclerosing agents to prevent lymphatic leakage into the renal pelvis.

Patients should ensure adequate sleep, maintain good indoor ventilation, and avoid infections.
