Specialized imaging like endoanal ultrasound (EAUS) and MRI are crucial for diagnosing complex anal fistulas. Advanced techniques aid in surgical planning and assessing treatment outcomes for better fistula cure prediction.

Area of Science:

  • Coloproctology
  • Diagnostic Imaging
  • Surgical Gastroenterology

Background:

  • Specialized imaging is vital for cryptogenic fistula-in-ano, delineating internal openings, track relationships, and sepsis effects.
  • Advanced imaging defines perirectal sepsis damage, guiding reconstructive surgery for anal fistulas.

Purpose of the Study:

  • To review and summarize the accuracy of endoanal ultrasound (EAUS) and magnetic resonance (MR) imaging in fistula management.
  • To correlate imaging findings with operative outcomes for cryptogenic and non-cryptogenic fistula-in-ano.

Main Methods:

  • PubMed search of English and non-English literature on fistula management outcomes.
  • Inclusion of studies detailing internal opening and horseshoe detection accuracy.

Main Results:

  • EAUS and MR fistulography are key imaging modalities, each with advantages and limitations.
  • Transperineal sonography is a new technique; pelvic phased-array MR imaging is necessary when EAUS has limitations.
  • EAUS shows promise for intraoperative image-guided drainage of recurrent abscesses.

Conclusions:

  • Coloproctologists require ultrasound skills for effective fistula treatment, suggesting imaging accreditation in training.
  • Future research should focus on cost-effective, predictive imaging algorithms for fistula cure.
