A perianal fistula is a small passage that forms between the anal canal and the skin around the anus, usually developing after an infection or abscess.
Most fistulas occur when an anal gland becomes blocked and inflamed. Other possible causes include Crohn’s disease, previous surgeries, or certain infections.
It may appear as a small bump, hole, or opening near the anus, often surrounded by redness and irritation, and may discharge pus or blood.
A seton is a medical thread inserted through the fistula tract to keep it open, allowing continuous drainage and promoting gradual healing.
Most patients heal within four to six weeks after surgical correction, though more complex fistulas may take longer to recover fully.
Some perianal fistulas require surgery for complete healing, but mild cases may respond well to antibiotics or other medical therapies.
You should consult a specialist if you experience pain, swelling, persistent drainage, or abscesses around the anus.
In many cases, a physical examination is sufficient. However, imaging tests such as MRI or ultrasound may be used to map the fistula tract before treatment.
Aftercare generally includes warm sitz baths, proper wound care, pain management, and regular follow-up visits to ensure healing and prevent complications.
