Laser Therapy in Perianal Fistulas

(1) Background: Perianal fistula represents a chronic local suppuration, and recurrent or incorrectly treated, this pathology has a negative effect on the life of patients. (2) Methods: A 12-month prospective study was conducted with a study group (patients at the second presentation) and a control group (patients at the first presentation). The BTL-6000 brand laser has 50 times the maximum power of conventional laser devices with an unmatched wavelength of 1064 nm and a tissue penetration power of up to 10 cm. It is highly effective in speeding up healing and pain management (3) Results: Transcutaneous high-intensity laser therapy of perianal fistulas proved effective with a promising positive impact on both symptomatology and local signs in the study group. As for the patients in the control group, 37 of them required a second hospitalization due to the recurrence of symptoms and to whom the same laser therapy was applied. (4) Conclusions: A beneficial and positive effect was observed in our study, mainly on the symptoms determined by the appearance of the perianal fistula, both in the short- and long-term. High-frequency laser therapy is of major importance, considering the lower costs compared to surgery as well as the discomfort created during local treatments.
