The laser uses stimulated emission of energy in the form of photons to create a monochromatic, coherent, and collimated beam of electromagnetic radiation. Today, lasers are used in various fields, including the manufacturing industry, telecommunications, construction, and the military industry. Soon after its discovery, laser technology was applied in medicine as well. Laser treatment methods for hemorrhoidal disease include laser hemorrhoidectomy, laser hemorrhoidoplasty, and HeLP (Hemorrhoid Laser Procedure). Laser hemorrhoidectomy is most commonly performed using a CO2 laser, and the technique is similar to open hemorrhoidectomy. Hemorrhoidoplasty is performed using a diode laser. The laser is applied submucosally to achieve the destruction of submucosal blood vessels and the formation of fibrous tissue. HeLP is a dearterialization method based on the occlusion of branches of the superior rectal artery through laser photocoagulation. For the treatment of perianal fistulas, laser ablation of the fistula tract is performed using a diode laser. This technique spares the anal sphincter and allows the healing of chronic fistulas through deepithelialization and obliteration of the fistula tract. Laser treatment of anal fissures involves the application of a CO2 laser to perform a modified form of partial sphincterotomy. Laser scanning is also used to stimulate regeneration and angiogenesis of the submucosa and skin. In terms of long-term results and reduced postoperative pain, there is still not enough sufficient evidence to suggest that laser hemorrhoidectomy achieves better outcomes than the conventional method. Laser hemorrhoidoplasty is a reliable method for treating second and third-degree hemorrhoids, with results comparable to traditional surgical approaches and a significant reduction in postoperative pain. HeLP is a suitable method for a limited number of patients with second and third-degree hemorrhoids without prolapse; however, further research is needed to confirm its advantages over other, more affordable techniques. Laser ablation of the fistula allows for the healing of perianal fistulas while preserving the sphincter, with a low rate of complications and incontinence. Laser treatment of anal fissures is currently not widely used, but the results of initial studies show satisfactory outcomes.
