How effective is laser treatment for an anal fistula, and what is the recovery process?

Laser ablation of the fistula tract (FiLaC) is a highly effective, sphincter-saving procedure. It uses laser energy to gently close the fistula tract without the need for large surgical cuts. This minimally invasive approach preserves the sphincter muscle, significantly reducing the risk of incontinence. Patients generally experience very little pain and can usually return to their normal daily activities within 2 to 3 days, with complete healing occurring smoothly over a few weeks.
