Proctologic diseases seriously disrupt normal daily activities — from discomfort and hygiene issues to severe complications such as chronic bleeding, infections, and debilitating pain
The application of surgical laser techniques has demonstrated high clinical effectiveness in the treatment of a wide range of proctologic diseases. Utilizing laser radiation at a wavelength of 1.94 microns, these methods offer significant advantages in the management of conditions such as rectal polyps, hemorrhoids, anal fissures, thrombosed knots, pararectal fistulas, and other rectal formations.
Laser energy is delivered precisely to the treatment site through a flexible fiber instrument, with the option for endoscopic application when necessary. Compared to traditional surgical approaches, laser-based interventions are associated with significantly better patient tolerance, reduced intraoperative trauma, and faster recovery.
Laser treatment offers broad clinical applications, including:
- Vaporization of internal and external hemorrhoids
- Management of anal fissures
- Removal of thrombosed hemorrhoidal knots
- Excision of anal fringes
- Elimination of pararectal fistulas
- Resection of various rectal lesions
Laser-assisted proctologic surgery enables outpatient treatment, reduces bleeding and recurrence rates, shortens recovery time, minimizes pain, and eliminates the need for sutures, ensuring efficient procedures.
Laser technology provides excellent coagulation, minimizes postoperative edema, and improves patient comfort, making it an effective solution for delicate proctologic interventions.
Technology
Laser therapy, particularly laser coagulation, is widely used for the treatment of hemorrhoidal disease, especially at stages II and III.
This minimally invasive technique effectively treats both internal and external hemorrhoids. Laser radiation generates controlled thermal energy, inducing coagulation of venous congestion. As a result, arterial and venous vessels are sealed, effectively preventing bleeding.The method demonstrates a clinical success rate of up to 98% and offers a favorable prognosis.
Treatment approaches differ depending on the type of hemorrhoid:-
For external hemorrhoids, the affected skin tissue is excised using laser energy.
-
For internal hemorrhoids, the laser vaporizes the nodule from within, minimizing trauma to surrounding tissues.
Laser hemorrhoid surgery is increasingly in demand due to its reduced pain levels, minimal invasiveness, and the fact that hospitalization is usually not required after external hemorrhoid removal, significantly enhancing patient recovery and comfort.

This high absorption enhances heat transfer and localized convection in tissues during EVLT, enabling effective vein closure at lower energy levels.
