|January 7, 2015
Summary
This case study details a rare extrasphincteric fistula originating from a retrorectal abscess. Successful surgical excision without a stoma highlights effective treatment for this unusual perianal fistula.
Area of Science:
- Colorectal Surgery
- Surgical Pathology
- Perianal Fistulas
Background:
- Retrorectal tumors are rare pathological entities.
- Extrasphincteric fistulas are a rare type of perianal fistula.
- This case presents a unique combination of a retrorectal abscess with an extrasphincteric fistula.
Observation:
- A patient presented with a retrorectal abscess that ruptured into the postanal space.
- Persistent drainage led to MRI and fistulography, revealing a cystic retrorectal formation with rectal communication, separate from the sphincter mechanism.
Findings:
- Complete surgical excision of the cyst and fistulous tract was performed.
- The rectum was repaired in two layers using slowly absorbable sutures.
- The patient experienced successful wound healing and normal defecation post-surgery.
Implications:
- This case demonstrates the successful primary surgical management of a rare extrasphincteric fistula secondary to a retrorectal abscess.
- Avoidance of a protective stoma was achieved, simplifying patient recovery.
- The findings support complete excision as an effective treatment strategy for similar complex perianal conditions.
