Common Questions

What are the main applications of lasers in proctology?

Modern, purpose-designed laser probes now allow effective treatment of a wide range of proctological conditions, including:

  • Haemorrhoids (LHP®)
  • Anal fistulas (FiLaC®)
  • Pilonidal sinuses / coccygeal fistulas (SiLaC®)
  • Anal fissures (Laser Fissurectomy)
  • Condylomata acuminata (anal and genital warts)
  • 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 lower rectum and surrounding areas.

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 pathological tissue while sparing adjacent healthy structures. This results in:

  • Greater surgical precision
  • Reduced blood loss and haemostasis requirements
  • Minimal damage to surrounding healthy tissue
  • Shorter operating time
  • Reduced postoperative complications
Can the laser procedures also be performed on an outpatient basis?

Yes. The laser procedures performed by Dr Chamisa are daycare procedures — meaning patients are admitted and discharged on the same day. Most procedures are performed under local anaesthesia, with no need for general anaesthesia or overnight hospital admission. Patients are typically able to return to their normal daily activities the same day or the day after the procedure.

Is Dr Chamisa specialised in treating haemorrhoids?

Yes. Dr Chamisa is a leading specialist in laser haemorrhoidoplasty (LHP®). He provides advanced laser treatment for both internal and external haemorrhoids, using minimally invasive techniques that significantly reduce pain and recovery time compared to traditional surgery. The LHP® procedure shrinks haemorrhoidal tissue from the inside without cutting or stitches, allowing patients to return to daily activities quickly and with minimal discomfort.

Does Dr Chamisa treat complex anal fistula cases?

Yes. Dr Chamisa has extensive experience treating simple, complex, and recurrent anal fistula cases. He utilises sphincter-preserving techniques — specifically the FiLaC® (Fistula-tract Laser Closure) procedure — to ensure high success rates while protecting bowel control and patient comfort. The FiLaC® technique seals the fistula tract using radial laser energy without cutting through the surrounding sphincter muscle, eliminating the risk of faecal incontinence.

Can chronic anal fissures be treated without traditional surgery?

In many cases, chronic anal fissures can be successfully managed by Dr Chamisa using non-surgical medical protocols or laser-assisted techniques. These modern approaches often eliminate the need for invasive hospital stays and long, painful recovery periods. Laser fissurectomy uses precise laser energy to vaporise pathological fissure tissue and stimulate natural healing — without tissue excision, without incontinence risk, and without the extended recovery associated with traditional surgical options.

Does Dr Chamisa treat pilonidal cysts without wide excision?

Yes. Dr Chamisa specialises in pilonidal cyst and sinus laser treatment using the SiLaC® (Sinus Laser Ablation) technique. This modern laser approach treats the cyst from the inside, avoiding the wide excision and large open wounds associated with traditional surgical methods. The procedure takes approximately 30 minutes, is performed on an outpatient basis under local anaesthesia, and allows for a much faster return to daily life compared to conventional surgery.

Are genital and anal warts treated with laser by Dr Chamisa?

Yes. Dr Chamisa provides precise laser removal of genital and anal warts. This method allows for the targeted removal of both external and internal lesions with minimal impact on surrounding healthy tissue, ensuring better cosmetic results and faster healing. Laser ablation is particularly effective for large or recurring clusters of warts that have not responded to topical creams or other conservative measures.

Is laser treatment painful and what is the recovery time?

Laser and minimally invasive treatments performed by Dr Chamisa are specifically designed to minimise patient discomfort. Most patients experience significantly less pain than with traditional surgery. The procedures are performed under local anaesthesia, so there is no pain during the procedure itself. Most patients are able to return to their normal daily activities the same day or the next day. There are no large cuts, open wounds, or sutures involved, and the risk of post-surgical infection is minimal. Dr Chamisa will provide specific aftercare instructions at the time of your procedure.
