Anal Fistula Surgery in Seomyeon, Busan
Anal fistula surgery treats an abnormal tunnel between the inside of the anal canal and the skin near the anus (치루), usually left behind after an abscess. In Seomyeon, Busan, colorectal clinics map the fistula by exam and sometimes ultrasound or MRI, then operate under spinal or general anesthesia, typically in 20–60 minutes, choosing a technique that balances cure with protecting continence.

What is an anal fistula?
An anal fistula is a small tunnel with an internal opening inside the anal canal and an external opening on the skin. Most develop after a perianal abscess drains, when the infected gland tract stays open. Fistulas are classified by how they relate to the anal sphincter muscles: low (simple) fistulas cross little muscle, while high or complex ones cross more muscle or have branches. Fistulas rarely heal on their own.
Symptoms and when to see a doctor
- A small opening near the anus that leaks pus, blood or stool
- Skin irritation and itching from discharge
- Recurring painful swelling that bursts and settles
- Pain when sitting or during bowel movements
Fever with a rapidly enlarging painful lump suggests an abscess and needs prompt drainage.
What happens at the clinic
- Examination: identifying the external opening and feeling the tract.
- Imaging: endoanal ultrasound or MRI for recurrent or complex fistulas.
- Planning: the surgeon explains how much muscle the tract crosses and the options.
- Surgery: under spinal or general anesthesia, the tract is probed and treated.
- Discharge: often the same day or after one night, with wound-care instructions.
Treatment outlook
Fistulotomy lays the tract open so it heals from the base; it has a high cure rate for low fistulas. A seton, a soft thread placed through the tract, drains infection and can be used in stages for higher fistulas. Sphincter-saving techniques such as LIFT (ligation of the intersphincteric fistula tract) and advancement flaps aim to close the internal opening without cutting muscle, with lower continence risk but higher recurrence. Crohn's-related fistulas usually need combined medical and surgical care.
Recovery and aftercare
Open wounds heal over several weeks and need sitz baths or showering after bowel movements and light dressings. Mild discharge is normal while healing. Keep stools soft. Attend wound checks so healing can be monitored and any bridging tissue addressed.
Risks and side effects
The main risks are recurrence and changes in continence, ranging from minor gas leakage to, rarely, more significant incontinence. Other risks include bleeding and infection. Choosing the right technique for the fistula's anatomy is key.
Choosing a clinic for anal fistula surgery in Seomyeon
- Ask how the surgeon classifies your fistula and whether imaging is needed first.
- Ask which sphincter-saving techniques the surgeon performs.
- Ask about expected recurrence and continence risks for your specific fistula.
- If you have recurrent or multiple fistulas, ask about screening for Crohn's disease.
- Clarify how wound care will be supported after discharge.
Getting there
Fistula care often involves several wound checks. Seomyeon, at the crossing of Busan Metro Lines 1 and 2, keeps those return trips short.
Key facts
- Symptoms: recurring discharge of pus or blood near the anus, swelling, pain
- Cause: most follow an anal gland abscess; some linked to Crohn's disease
- Mapping: exam under anesthesia, endoanal ultrasound or pelvic MRI for complex tracts
- Techniques: fistulotomy, seton, LIFT, advancement flap
- Procedure time: about 20–60 minutes
- Downtime: desk work often in about 1–2 weeks; wounds heal over several weeks
- Key risk: recurrence vs continence, depending on how much muscle the tract crosses
Frequently asked questions
Can an anal fistula heal without surgery?
Fistulas rarely heal on their own. Antibiotics may calm infection but do not close the tract. Surgery is usually needed, except in some Crohn's cases managed with medication.
Will fistula surgery affect bowel control?
For low fistulas, the risk is small. For fistulas crossing more muscle, surgeons use setons or sphincter-saving methods to protect continence. Ask your surgeon about your specific risk.
What is a seton?
A seton is a soft thread or band placed through the fistula tract. It keeps the tract draining to prevent abscesses and can be part of a staged treatment plan.
How long does a fistula wound take to heal?
It depends on the size and depth. Many fistulotomy wounds heal in about four to eight weeks, while complex fistulas can take longer.
Can a fistula come back after surgery?
Yes, recurrence is possible, especially with complex fistulas or sphincter-saving techniques. Careful mapping and choosing the right operation reduce the risk.
