An anal fistula is a small tunnel that forms between the skin near the anus and the anal canal. Fistulas typically develop from an infection that started in an anal gland, which then spreads and creates a channel filled with pus. This causes pain, swelling, drainage, and sometimes fever. Because fistulas don't close on their own and can lead to serious complications including recurrent abscesses and continence problems, timely treatment is essential.
Most anal fistulas start as anal abscesses. An abscess forms when anal glands become clogged and infected, producing a painful collection of pus. As the infection progresses, the body often creates a pathway to drain the pus, and that pathway is the fistula. Roughly half of people with an abscess end up developing a fistula.
While most fistulas come from abscesses, other causes include Crohn's disease (which can produce complex perianal fistulas), sexually transmitted infections, trauma, diverticulitis, tuberculosis, or radiation exposure. Identifying the underlying cause matters because it shapes treatment.
Fistulas are classified by their relationship to the anal sphincter muscles. The type determines which treatment approach will work and how carefully sphincter function needs to be protected.
Preserving sphincter function is a key priority in fistula surgery. Complex fistulas involving significant sphincter muscle are typically treated with sphincter-sparing techniques rather than direct division of muscle.
Fistula symptoms tend to be persistent and recurrent, which is one of the clearest signs you're dealing with one.
These can indicate an active abscess or spreading infection that may require urgent drainage.
During your initial consultation, Dr. Chung will thoroughly review your symptoms and medical history. A gentle physical examination often identifies the fistula directly. Additional testing helps characterize complex fistulas and their relationship to the sphincter muscles.
While professional treatment is ultimately needed to resolve a fistula, supportive home care can ease symptoms and keep you comfortable in the meantime. Warm sitz baths (soaking the anal area in warm water for 10 to 15 minutes, 2 to 3 times daily) reduce pain and inflammation. Good hygiene, gentle cleaning after bowel movements, and soft pads to absorb drainage all help. Dietary adjustments to keep bowel movements soft, along with over-the-counter pain relievers and stool softeners, can make a real difference while you wait for treatment.
Surgery is the primary treatment for anal fistulas. The specific procedure depends on the fistula type, complexity, and how much sphincter muscle is involved. Protecting continence is a core consideration in every treatment decision.
Dr. Chung also offers laser fistula treatment (FiLaC) as a minimally invasive option. For detail, see the laser treatment page.
Perianal fistulas in Crohn's disease are often more complex and recurrent than typical cryptoglandular fistulas. Treatment usually combines medical therapy (biologics like anti-TNF agents) with conservative surgical approaches (often a long-term seton to maintain drainage without aggressive surgery). The goal is controlling symptoms and preserving function rather than attempting definitive repair of every tract.
Recovery timelines depend on the procedure. Most patients resume normal activities within a few weeks. Sitz baths several times daily, careful hygiene, soft stools (supported by fiber and adequate hydration), and activity restrictions during initial healing are all part of the aftercare plan. Dr. Chung provides detailed post-operative instructions and schedules follow-up appointments to confirm healing and reduce the risk of recurrence.
Whether you're dealing with a new fistula, a recurrent one, or complex Crohn's-related perianal disease, Dr. Chung can walk you through the right treatment for your situation.

Dr. Chung utilizes minimally invasive techniques and effective pain management strategies to minimize discomfort during recovery.
Recovery can vary but generally ranges from a few weeks to several months, depending on the complexity of the fistula and the chosen treatment method.
