Pus Discharge from a Fistula

What is it?

A fistula is an abnormal channel that connects an internal organ or cavity to the surface of the body or another organ. Pus discharge from a fistula indicates an infection or inflammatory process requiring prompt medical attention.

Causes

• Chronic infections. Long-standing inflammatory conditions such as osteomyelitis or tuberculosis.
• Abscess rupture. The bursting of an abscess can lead to fistula formation.
• Postoperative complications. Improper wound healing after surgery.
• Crohn’s disease. A chronic inflammatory bowel disease.
• Periodontal diseases. Fistulas may form in the gum area.

Symptoms

• Purulent discharge from the fistula.
• Redness and swelling around the fistula.
• Pain near the fistula, worsened by pressure.
• Foul-smelling discharge.
• Fever (in cases of acute inflammation).

Diagnosis

• Fistulography. X-ray imaging with contrast dye to evaluate the fistula tract.
• Bacteriological analysis. Identifies the causative pathogen.
• Ultrasound of soft tissues. Assesses the extent of the inflammatory process.
• MRI or CT scan. Provides detailed imaging for complex fistulas.

Treatment

• Surgical removal. Removal of the fistula tract and drainage of the area.
• Antibiotic therapy. Targets bacterial infections.
• Topical treatment. Use of antiseptics and sterile dressings.
• Physiotherapy. Promotes faster healing (e.g., laser therapy).
• Prevention. Timely treatment of infections and good hygiene practices.
