Anal fistula
A condition that often follows a perianal abscess and usually requires surgical treatment. Everything here is private, anonymous, and written to help you understand the journey ahead.
At a glance
An anal fistula is a small abnormal tunnel that forms between the inside of the anal canal and the skin near the anus. It most commonly develops after a perianal abscess has drained. Around half of perianal abscesses are reported to develop into a fistula. Treatment usually involves some form of surgery, with the approach depending on the fistula's path and complexity. Our basics guide covers how fistulas form, what to expect, and when to seek care.
Common symptoms people report
- Persistent or recurring drainage near the anus
- Pain or discomfort, especially during bowel movements
- Swelling that comes and goes in the same area
- An external opening near the anus that may discharge fluid
- A recurring abscess in the same location
- Skin irritation from ongoing drainage

Read experience →Common questions
How common are anal fistulas?
Anal fistulas are less common than hemorrhoids or fissures, but they are not rare. They are one of the conditions most frequently treated by colorectal surgeons. They are more common in men and most often appear between the ages of 20 and 40.
What is the connection between an abscess and a fistula?
A perianal abscess is typically caused by an infected gland inside the anal canal. When the abscess drains — either on its own or surgically — the tunnel it creates sometimes does not close fully. That persistent tunnel is a fistula. Not every abscess leads to a fistula, but roughly half are reported to.
Are there different types of fistula surgery?
Yes. The approach depends on the fistula's path relative to the sphincter muscles. Simpler fistulas may be treated with a fistulotomy, where the tunnel is laid open to heal from the inside out. More complex fistulas may need a seton (a thread placed through the tunnel) or other techniques to protect the sphincter. We have guides covering both fistulotomy and seton placement.
How long is the recovery from fistula treatment?
Recovery varies depending on the procedure and the individual. People commonly report several weeks of wound care and gradual improvement. Some complex fistulas require staged treatment over months. Our experience stories cover what recovery looked like for different people in different situations.
Can a fistula come back after surgery?
Recurrence is possible, particularly with more complex fistulas. Rates vary depending on the type of fistula and the procedure performed. Follow-up with your surgeon is important to monitor healing and catch any signs of recurrence early.
