Complex fistulas and advanced soft tissue techniques

Perianal fistulas are categorized as “complex” under the following conditions: a high tract passing the upper two third of the external sphincter, presence of multiple fistula tracts, rectovaginal fistulas, previous local irradiation, and association with the presence of an anorectal stricture or Crohn's disease. Treatment of complex fistulas can be challenging and carries a high risk of poor wound healing, recurrences and incontinence. Therefore a detailed understanding of perianal anatomy, knowledge of the extent of the disease and its relation to the various structures is required for proper management.
