A perianal fistula is a small tunnel that forms between the anal canal and the skin near the anus, usually following an infection or abscess.
Most fistulas begin when an anal gland becomes blocked and infected. Conditions such as Crohn's disease, past surgeries, or other infections can also contribute.
It often appears as a small bump, hole, or opening near the anus and may leak pus, blood, or fluids, sometimes accompanied by redness and irritation.
A seton is a medical thread placed through the fistula tract to keep it open, allowing continuous drainage and promoting healing.
Most patients heal within four to six weeks after surgical treatment, though complex fistulas may require a longer recovery period.
While many perianal fistulas require surgical intervention for complete healing, mild cases may respond to antibiotics or other medical therapies.
You should consult a specialist if you experience pain, swelling, persistent drainage, or recurrent abscesses near the anus.
A physical exam is often sufficient, but imaging tests such as MRI or ultrasound may be used to map the fistula tract before treatment.
Aftercare typically includes sitz baths, proper wound hygiene, pain management, and follow-up visits to monitor healing and prevent complications.
At GastroDoxs in Houston, our specialists offer expert, compassionate care using modern techniques, clear communication, and a personalized approach from diagnosis through recovery.
