Abstract
Anal fistula (AF) presents a chronic problem for patients and colorectal surgeons
alike. Surgical treatment may result in impairment of continence and long-term risk
of recurrence. Treatment options for AFs vary according to their location and complexity.
The ideal approach should result in low recurrence rates and minimal impact on continence.
New technical approaches involving biologically derived products such as biological
mesh, fibrin glue, fistula plug, and stem cells have been applied in the treatment
of AF to improve outcomes and decrease recurrence rates and the risk of fecal incontinence.
In this review, we will highlight the current evidence and describe our personal experience
with these novel approaches.
