Treating hemorrhoids and anal fistulas – the minimally invasive alternative to surgery

Minimally invasive, tissue-friendly, effective: as a tried and test therapy method, laser therapy has long been established in proctology. It enjoys high acceptance among patients because it has hardly any side effects and can be performed quickly. It offers many other significant advantages over conventional procedures, including being less invasive, shorter convalescence periods and less postoperative pain.

Laser therapy is most commonly used in proctology for treating hemorrhoids. It is also used for the removal of polyps and genital warts. Lasers can also be used to treat anal fistulas and coccygeal fistulas and are effective for fissures.

With innovative devices, such as the intros dios:1470, and in combination with laser fibers, such as the intros Fistula Fiber, we provide the perfect tools to start or expand the use of this innovative treatment method.

Laser therapy in proctology

Technology and mode of operation

Treating hemorrhoids (HOLT®)
In the treatment of hemorrhoids, the so-called laser hemorrhoidoplasty has shown good results. The safe, painless and minimally invasive treatment method called HOLT® (= hemorrhoid occlusion laser therapy) uses a fan-shaped emitting hemorrhoid laser probe developed specifically for this treatment. It enables the gentle shrinkage of grade 2 to 4 hemorrhoids requiring treatment. Pinpoint coagulation ensures the best possible preservation of the surrounding tissue and reduces side effects on the sphincter and anal mucosa.

Treating anal fistula (FOLT®)
There are a number of benefits to lasering anal fistulas, such as coccygeal fistulas, instead of having surgery. With the FOLT® method (= fistula occlusion laser therapy), a flexible, diffusely emitting fistula laser probe is inserted into the fistula tract, the inflamed tissue is destroyed in a controlled manner, the fistula tract is closed and the original anal gland is inactivated. The fistula tissue is destroyed in a gentle way, meaning it is possible to dispense with scooping the fistula out of the healthy tissue. Another advantage of proctological laser surgery is that it spares the sphincter muscle and prevents anal faecal incontinence.


Fistula or hemorrhoid treatments using laser are gentler than conventional surgical procedures. Healing is usually very good because, unlike conventional surgery, no incisions or sutures are necessary.


Minimally invasive treatment
Protection of the surrounding tissue
Small wound size and excellent haemostasis
Effective and safe treatments
Reduction of local side effects
Low pain sensation and less postoperative pain
Excellent cosmetic results
Combinable with other methods


The benefits of laser proctology surgery are found in the minimally invasive method. There are no incisions or only small incisions, resulting in a positive effect on the healing process. Large wounds, long healing times, postoperative pain or infections due to contamination in the anal region are a thing of the past because, in contrast to a conventional hemorrhoidectomy or coccygeal fistula operation, no extensive tissue removal is required.
