A perianal fistula is a small tunnel that forms under the skin between the anal canal or rectum and the skin around the anus. It often begins after an infection or abscess in one of the anal glands. In people with Crohn's disease, chronic inflammation can lead to repeated fistula formation. Early on, you may not see an opening, but the tract can leak pus or fluid.
Watch for these warning signs:
A perianal fistula most often starts with an infected gland that forms an abscess. If the abscess drains or is treated, a persistent tract may remain. Other factors that can lead to fistula formation include:

Hemorrhoids generally cause itching, discomfort, and bright red bleeding during bowel movements. A perianal fistula, however, often leaks pus or fluid, causes persistent deep pain, and may be associated with swelling and recurrent infections.
Small abscesses sometimes resolve with antibiotics and warm sitz baths, but many require a minor procedure to fully drain the infection and prevent fistula formation.
A simple fistula has a single, short tunnel close to the skin surface. A complex fistula features multiple branches, deeper tracks through muscle layers, or involvement of other pelvic structures.
Imaging studies like CT or MRI provide detailed views of the fistula's path, helping your doctor plan the most effective treatment and reduce the risk of recurrence.
Recurrent fistulas can occur, especially in patients with Crohn's disease. Regular follow-up appointments and targeted medical therapy help minimize this risk.
Recovery typically takes one to three weeks, depending on the procedure's complexity and individual healing rates. You may need time off work and follow-up visits for wound care.
All surgeries carry risks such as infection, bleeding, or changes in bowel control. Your surgeon will discuss these risks and take steps to preserve sphincter function and promote healing.
While a high-fiber diet and adequate hydration help soften stools and reduce pressure, dietary changes alone cannot close a fistula. Medical or surgical intervention is usually necessary.
Surgery costs vary based on the procedure type and imaging requirements. We provide transparent, itemized estimates and discuss payment options before any treatment begins.
Consult a specialist if you experience persistent anal pain, notice pus or blood near the anus, have swelling, or if symptoms don't improve with home care within a few days.
