Proctology
Gentle and Modern Treatment Options in Laser Proctology
Wide range of applications in benign
(colo-)rectal diseases
Thanks to innovative advances in laser technology and customized light guides, it is now possible to replace traditional surgical procedures on the lower rectum with painless, minimally invasive solutions. Whereas the focus was previously on excising diseased tissue, modern medical lasers enable the precise, targeted destruction or controlled shrinkage of pathological areas while preserving healthy surrounding structures.
Chasing the better patient outcome
Benefits of the technology
Minimally invasive laser procedures are a patient-friendly treatment option in proctology. Fiber optics with a diameter of less than 2 mm mean minimal wounds, which have taken patient comfort to a new level.
- Painless
- Controlled hemorrhoidal shrinkage
- Very good hemostasis
- Low risk
- Maximized preservation of continence
- Quality of life improvement
- Small wound sizes
The therapeutic principle centers on controlled tissue remodelling that harnesses the body’s intrinsic regenerative capacity. This leads to more patient comfort through minimal postoperative pain and a rapid return to normal activities.

Applications
Hemorrhoids (LHP®)
The LaserHemorrhoidoPlasty (LHP®) approach is used for the treatment of advanced hemorrhoids under appropriate anesthesia. The energy of the laser is introduced centrally into the hemorrhoidal cushion. Using this technique, the hemorrhoid can be treated according to its size without causing any damage to the anoderm or mucosa.
In-depth clinical recommendations about the LHP® procedure, including many references to the scientific literature, have been published by a recommendation development group (RDG) consisting of experienced surgeons.
Sinus pilonidalis (SiLaC®)
Sinus laser ablation of the cyst (SiLaC®) is the ideal treatment to heal the sinus tract, preserve the overlying skin and prevent recurrence. This simple, minimally invasive procedure – performed under local anesthesia on an outpatient basis – shortens recovery, reduces postoperative pain and wound care requirements, and provides excellent cosmetic results.
A systematic review of the laser treatment of Pilonidal Disease (PD) has been published in the journal Lasers in Medical Science.
Anal fistulas (FiLaC®)
Fistula-tract laser closure treatment (FiLaC®) aims at gently removing the fistula tract without damaging the sphincter. That way, any parts of the muscle are maximally preserved while incontinence is avoided. Furthermore, the FiLaC® procedure offers a minimally invasive approach which can be performed in just a few minutes as the laser action replaces the excision.
In-depth clinical recommendations about the FiLaC® procedure, including many references to the scientific literature, have been published by a recommendation development group (RDG) consisting of experienced surgeons.
Anal fissures
AIN/Condylomata
HPV-associated lesions of the anus, vagina or scrotum can be precisely ablated with controllable spot size and geometry using a bare fiber or the LOMA handpiece. This technique keeps tissue defects to a minimum and reduces the need for repeated procedures.
Hidradenitis Suppurativa
Fistulous tracts, particularly in the axilla or other affected areas, traditionally require wide excisions that result in large wounds. Laser ablation selectively destroys the primary fistula tracts while sparing healthy tissue, thereby avoiding extensive surgical excision. Optimal outcomes are obtained using biologics therapy to suppress the inflammatory stages.

The diode laser has established itself as a flexible tool for us - from hemorrhoids to fistulas to fissures. The minimally invasive procedure, shorter downtime, and high patient satisfaction are significant advantages in our daily proctological practice.
PD Dr. med. Dietmar Jacob, MBA
For chronic anal fissures, we use the diode laser for precise, tissue-preserving treatment. The controlled ablation of hardened fissure edges can support healing and is generally very well tolerated by patients.
Dr. Guido Weyand
The diode laser enables us to selectively shrink hemorrhoidal tissue without the need for larger incisions. Patients generally report significantly less postoperative pain and a faster return to daily activities.
Bernd Bolik
Especially in complex anal fistulas, the laser offers a gentle alternative to radical fistulotomy. Sphincter function is preserved, and the risk of incontinence is significantly reduced. This makes the diode laser a valuable component of our treatment spectrum.

Frequent Questions
What are the main applications of lasers in proctology?
Modern, purpose-designed laser probes now allow effective treatment of:
- Haemorrhoids
- Anal fistulas
- Pilonidal sinuses / coccygeal fistulas
- Anal fissures
- Condylomata acuminata
- Anal intraepithelial neoplasia (AIN)
- Hidradenitis suppurativa (acne inversa)
What are the advantages of laser proctology for the surgeon?
Laser procedures in proctology represent a gentle, precise and highly efficient treatment option for a broad spectrum of pathologies affecting the distal 15 cm of the rectum as well as the coccygeal region.
Operating primarily at a wavelength of 1470 nm, the laser’s penetration depth in soft tissue can be finely controlled between 0.5 and 4 mm. This is achieved through the strong absorption of this wavelength by water, enabling highly selective targeting of the pathological lumen while sparing adjacent healthy tissue.
Can I use the same laser for different procedures in laser proctology?
Yes, lasers like the biolitec® DUAL 45 can be used for all the listed treatments such as haemorrhoids, anal fistulas, anal fissures, pilonidal sinuses, condylomata acuminata etc. These sometimes require different fibers or handpieces, which are all available from biolitec®. This makes for a versatile system and fast ROI.
Which fiber/handpiece do I need for different laser proctology applications?
All the listed procedures can be performed with the biolitec® DUAL 45 laser. Here are the fibers you need for each application:
· Hemorrhoids (LHP®): LHP fiber
· Sinus pilonidalis (SiLaC®): SiLaC fiber
· Anal fistulas (FiLaC®): FiLaC fiber
· Anal fissures: Bare fiber or LOMA handpiece
· AIN/Condylomata: Bare fiber or LOMA handpiece
Which parts do I need for a minimally invasive laser system that can be used for laser proctology?
Generally, a system suitable for laser proctology applications consists of the laser itself (such as the biolitec® dual-wavelength diode laser DUAL 45), a corresponding fiber and a handpiece. Accessories are available as well.
Can the laser procedures also be performed on an outpatient basis?
Yes, some of the treatments in proctology can be performed on an outpatient basis.
As a surgeon, how can I learn laser proctology?
biolitec® regularly organizes workshops at international centers of expertise that teach both theoretical and practical fundamentals. They are designed to assist physicians learn the procedure faster and apply it in a safe way. Contact us to learn about upcoming trainings and reserve your spot!
What is the difference between contact and non-contact fibers/laser applications?
Contact fibers (such as our bare fibers) are applied directly to the tissue and are used for cuts, whereas non-contact fibers are held above the tissue, while the laser beam enters the tissue at a distance. The non-contact approach is ideally suited for ablation and coagulation.
As a practitioner, where can I find more data, references, and general information about laser proctology treatments and systems?
Have a look at the recent publications by the International Society of Laser Proctology for in-depth recommendations of the LHP®, FiLaC® and SiLaC® treatments. These contain a host of data and references, as well as practical information for practitioners.
