Abstract Several biomaterials have been proposed to treat anal fistula alone or in combination with other surgical procedures aiming to reduce recurrence rates while minimizing continence impairment. More recently a porcine dermal matrix injection has been proposed as infill biomaterial to treat fistulae. We propose an approach consisting of non‐cutting seton positioning followed several weeks later by flap repair associated with dermal matrix injection into the fistula tracts. We report our experience with this two‐staged procedure on 24 consecutive patients with complex anal fistulae with a median follow up of > 12 months. In our experience this two‐stage approach seems to be safe and effective.
