The Use of Biologic Mesh for Repair of Perianal Fistulas.

This is a case series of three patients who presented with complex anorectal fistulas. Each patient underwent repair of complex anorectal fistulas with biologic mesh. We will discuss each case and our institution's experience with this relatively new technique. This case series demonstrates the use of biologic mesh for the repair of complex anorectal fistulas. Three patients are discussed who underwent repair of perianal fistulas using ACell mesh by two separate surgeons. We will discuss the rationale for offering this treatment, as well as the advantages and disadvantages. The use of biologic mesh in perianal fistulas is a relatively new topic that needs further investigation. Perianal fistulas can be difficult to manage for both patients and surgeons. There are many options for repair, ranging from simple to complex. Biologic mesh for complex fistulas may be a useful option to avoid the morbidity of more complex repairs, such as flaps.
