Anorectal Abscess Overview

Characterized by anal or perianal pain, swelling, and induration.
Purulent or bloody drainage may occur during infection.
Severe cases can lead to perineal sepsis.
Particularly concerning in diabetic or immunocompromised patients.

Clinical Diagnosis

Imaging studies are essential for complex or recurrent cases.
Common imaging techniques include:
- Fistulography
- Endoanal ultrasonography
- CT scan
- Pelvic MRI
Imaging helps determine the type and extent of fistulas and informs surgical planning.

Fistula Types

Four main types of anal fistulas:
- Intersphincteric Fistula: Located between sphincters.
- Transsphincteric Fistula: Traverses both sphincters.
- Suprasphincteric Fistula: Arises from supralevator abscess.
- Extrasphincteric Fistula: Rare but problematic.

Management Guidelines

Surgical drainage is the treatment of choice for anorectal abscess.
Antibiotics are generally unnecessary except for specific patient populations (diabetics/immunocompromised).
Fistulotomy, a standard treatment for anal fistulas, may be postponed if the internal opening isn’t visible during surgery.

Fistulotomy Procedure

Involves opening the fistula tract and performing curettage.
Marsupialization might be done to aid in healing.

Essential Features of Anorectal Abscess and Fistula

Horseshoe abscesses can develop in various spaces:
- Intersphincteric space
- Ischiorectal space
- Supralevator space
