Long-term follow-up after FiLaC™ seems to confirm the favorable short-term success rates reported for this procedure. Although sealing of chronic anal fistulas may be obtained with FiLaC™ in a single treatment, our current strategy consists of placing a loose seton into the fistula tract a few weeks prior to laser treatment. Seton treatment facilitates the following laser procedure and seems to have favorable effects on healing.
The laser FiLaC™ procedure for fistula-in-ano is a safe, relatively simple, minimally invasive, sphincter-saving procedure with a high chance of success.
