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
Parkes and Gordon Classification
- Framework for categorizing anorectal fistulas based on anatomical locations and involvement of sphincters.
