Comparison of laser ablation, simple excision, and flap reconstruction in the treatment of pilonidal sinus disease

Pilonidal sinus disease (PSD) is a common condition that typically affects young adults. PSD may cause significant morbidity due to its chronic nature and tendency to recur. Laser ablation has recently shown promising results in the treatment of PSD, but comparative studies are sparse. We aimed to compare laser ablation with two conventional treatment options: simple excision with direct closure and excision with flap reconstruction. This retrospective study material included patients who underwent PSD surgery in the plastic surgery department of a single academic teaching hospital. Patients were divided into three groups based on the operation technique: laser group, direct closure group, and flap group. Preoperative and postoperative data were compared between the groups including patient characteristics, residual disease, recurrent disease, complications, and re-operations. Among the 278 patients, 66 underwent laser treatment, 134 excision with direct closure, and 78 excision with flap closure. The follow-up time ranged from 15.4 +/- 7.6 months in the laser group to 87.6 +/- 29.3 months in the flap group. Eventless healing occurred in 67.7% of the patients in the laser group, 66.4% of the patients in the direct closure group, and 56.4% of the patients in the flap group. There was significantly more residual disease in the laser group whereas significantly more complications were found in the direct closure and flap groups. The advantages of laser treatment include fast postoperative recovery and reduced risk of complications.
