Why Do Anal Fistulas and Perianal Abscesses Recur? Updated Diagnosis and Treatment
A perianal abscess is an inflammatory focus; an anal fistula is often a tunnel that develops after abscess. Accurate diagnosis and sphincter preservation reduce recurrence.
Why an abscess does not resolve on its own
An abscess may briefly drain and feel better, but if the underlying source persists, swelling and discharge can recur. Fever, severe pain or a rapidly enlarging swelling needs urgent care.
Why fistulas recur
- Internal opening not addressed
- Tract incompletely mapped
- Complex branching
- Underlying conditions such as Crohn's
- Staged treatment to protect the sphincter
When is MRI needed?
MRI helps in recurrent, complex, high or multi-tract fistulas — clarifying the tract's relation to the sphincter and detecting hidden abscess pockets.
Why a seton is placed
A seton helps control infection and maintain drainage, especially in sphincter-involving fistulas, while preserving continence. It is sometimes part of a staged plan rather than a final solution.
Treatment goals
Treat the fistula and preserve continence. Fistulotomy, seton, advancement flap, LIFT, laser or other techniques are tailored to each patient — no single method fits everyone.
