Laser removal of pilonidal cyst (SiLaC) is an effective, minimally-invasive and safe treatment method, which can be carried out in ambulatory conditions, under infiltration anaesthesia.

Pilonidal cyst

Pilonidal cyst is a chronic, complex inflammation in the coccygeal region, in the cleft between the buttocks, often causing discomfort to the patient and making him uncomfortable. If the appropriate treatment is not applied, it can cause painful symptoms. If the appropriate treatment is not applied, it can cause painful symptoms. In the acute phase, symptoms of acute general inflammation, such as severe pain of the affected spot, fever, shivers and skin redness in the coccygeal region, are most noticeable.

In the chronic phase the illness usually does not show any symptoms for years, from time to time producing pus or bloody pus discharge with specific unpleasant odour. Bearing in mind those symptoms, to receive more precise diagnosis you should approach a surgeon, who, with the help of an ultrasound scan, can assess the lesion and make a final diagnosis. The pilonidal cyst is easy to confuse with anal fistula, but by differentiating, also anal abscess and skin lesions typical in the course of tuberculosis and Crohn disease should be considered.

Determining eligibility for treatment:

The decision about the procedure is made during an eligibility consultation Based on patient's test results and their overall health condition, a decision is made about the procedure and a suitable date is arranged. The laser ablation of pilonidal cyst method (SiLaC) is effective, minimally-invasive and safe treatment method. It can be conducted as an outpatient treatment under infiltrative anaesthesia

The procedure:

After the anaesthesia has been administered and the surgical field has been prepared, the pilonidal cyst is cut in its upper end. Using a probe, the channels of the sinus tract are broadened. Subsequently, a laser radial fibre is inserted to the sack of the cyst and laser ablation of its walls is conducted, using a 1470nm wavelength laser. A surgical spoon is used to clean the sack and the sinus tract from the skin debris and hair. After the procedure a sterile dressing is applied. Directly after the conclusion of the procedure the patient is able to leave the treatment room and go home.

Recommendations after treatment:

- in the initial period it is essential to change the dressing every day and sanitize the wound with a sterilising solution
- after a couple of days, the wound can be cleaned with soap water
- until the wound is healed, dressings should be used

The effectiveness of pilonidal cyst treatment with laser ablation is considered to be 90.3% effective during the first session. For patients who required repeated ablation, the effectiveness of the second procedure was estimated to approx. 78.3% The healing of the surgical wound takes approximately 4-6 weeks.
