It involves the radial dissipation of laser energy in the fistula tract and, through a combination of coagulation and shrinkage of the tract, is proposed to result in progressive sealing of fistulas. Early studies have suggested minimal impact on continence and touted the advantage of minimal morbidity with potential of repeat procedures if the technique fails initially. Despite early promising results, ten years on, questions remain on the technique, patient selection and long-term outcomes. This narrative review assesses the evidence reported to-date of radially emitting laser fistula surgery in the treatment of perianal fistulas.Keywords: fistula, surgery, FiLaC, fistula laser closure, perianal fistula, perianal Crohn’s disease
