An effective and considerable treatment of pilonidal sinus disease by laser ablation.

The treatment of sacrococcygeal pilonidal disease (SPD) is still challenging. Although many non-surgical and surgical methods exist, no consensus has been reached on the best treatment. This study aimed to evaluate the efficacy of laser ablation using 1470-nm radial diode laser fiber in treating SPD. We retrospectively studied the data of our 48 patients who operated on this technique between March 2019 and July 2022. All patients were treated with laser ablation using 1470-nm radial diode laser fiber. The healing rate and recurrence rate, demographic and surgical data, postoperative pain, complications (wound infection, wound bleeding), the time of returning to regular work and life, and the time of wound healing were recorded. Postoperative pain was measured based on the visual analog scale (VAS) score. Postoperative follow-up was performed in the outpatient clinic every 1 week for 1 month. Among the 48 patients, 41 males and 7 females, with a mean age of 27.7 years (range 14-42), the healing rate was 100%, and the average healing time was 28.3 ± 5.5 days. Mean operative time was 15.5 ± 3.3 min. The recurrence rate was 2.1%. One patient relapsed 3 months after the operation. The patient underwent laser ablation again, and the sinus tract was closed. The median visual analog scale (VAS) score on the day of operation was 0(0,2). The median VAS score on the first, third, seventh, and fourteenth day after operation was 0(0,2), 0(0,1), 0(0,1), and 0(0,0), respectively. There was no wound infection or bleeding after the operation. The mean time to normal work/life was 7.1 ± 3.2 days. Almost all the patients felt very satisfied with the operation. Laser ablation using 1470-nm radial diode laser fiber is effective in SPD treatment. It is associated with minor wounds and mild postoperative pain. It is a simple, safe, and minimally invasive technique and its clinical application for acute and chronic SPD in the absence of abscess is promising.
