Abstract

Aim: In recent years, the paradigm for the treatment of sacrococcygeal pilonidal sinus disease (SPSD) has shifted from surgical excision toward more minimally invasive techniques. Although extensive research has been conducted on the minimal invasive phenolization technique for primary SPSD, literature in recurrent SPSD is lacking. The purpose of this study was to report the long-term outcomes of the phenolization technique for recurrent SPSD. Method: This study included all 57 patients who were initially prospectively included in this study for short-term follow-up after phenolization for recurrent SPSD. A questionnaire was sent out to all patients to obtain long-term outcome. The primary endpoint was recurrence. Secondary endpoints included quality of life and symptoms related to SPSD. Results: A total of 47 patients (82.5%) were available for long-term follow-up. Recurrence needing further surgery developed in 7 patients (14.9%) after a mean follow-up of 76 (SD 21.7) months. At follow-up, there was improvement in the quality of life compared to preoperative levels (82.0, IQR 75.0–90.0 versus 74.0 IQR 52.5–80.0, p = 0.024). Additionally, symptoms associated with SPSD, including pain, fluid discharge, and itching sensation, also showed significant improvement. A total of 42 patients (89.4%) would undergo the same treatment again. No significant association was found between known risk factors and recurrence. Conclusion: Phenolization for recurrent SPSD showed a recurrence rate of 14.9% with significant improvement of natal cleft symptoms and quality of life at long-term follow-up. Therefore, phenolization should be considered as a feasible option for patients with recurrent SPSD.
