There are limited data available concerning laser treatment of pilonidal disease. Our study demonstrates a single institution first experience with SiLaC® (Sinus Laser-Assisted Closure, Biolitec, Germany) and analyzes outcomes of this novel approach in pilonidal sinus management.



In a prospective study, we analyzed the first 12 patients who underwent laser treatment of pilonidal disease. The aim was to determine the success of pilonidal sinus healing and one-year outcomes (recurrence rate, complications and cosmetic result).



The study analyzed 12 patients treated in a University Hospital, at the Day Surgery Unit over a follow-up period of 12 months. None of the patients had earlier excisional procedure done, but five patients had previous urgent drainage of acute pilonidal abscess. Local anesthesia was used in 8 and general in 4 patients. Patients were discharged on the same day between 4-8 hours postoperatively. One year recurrence rate was 8% (1/12) and complications occurred in just one patient presenting as abscess formation on postoperative day 3, which was successfully treated by incision, drainage and antibiotic therapy. The mean duration of complete orifice closure was 28 days (range 12-41 days).The majority of patients (11/12) were very satisfied with overall cosmetic result after 1 year.



SiLaC® is a promising minimally invasive alternative to other methods of pilonidal disease management and it could represent a first-line therapy for less extensive disease. Quick recovery, possibility to utilize

local anesthesia and acceptable cosmetic result are main advantages of this technique, but future larger clinical studies are required to evaluate long term results of this procedure.
