PURPOSE: Severe pilonidal diseases have refractory symptoms despite multiple surgeries and optimal therapy remains unclear. We hypothesized that standardized minimally invasive protocol could be an effective rescue treatment. METHODS: We prospectively collected data from symptomatic patients who underwent ≥ 1 pilonidal excision prior to presentation at our clinic 2019-2023. We treated these patients with standardized protocol incorporating local wound care, regular manual/laser epilation, and selective debridement/pit trephination. RESULTS: We treated 34 refractory patients (23 males) with median follow-up 405 days. Median age of first symptoms was 17.1 years; presentation to our clinic 20.0 years. Prior to our clinic, 27 received one surgery (cleft lift-2, excision no closure-1, excision primary closure-18, wound vac after excision-3, excision flap closure-3); 7 had two surgeries (excision without closure + cleft lift-1, primary closure after excision twice-3, flap closure after excision twice-2, excision primary closure + excision without closure-1). We treated all patients with regular epilation ± local wound care. 14 (41%) underwent trephination ± debridement. All patients achieved complete resolution after median 52 days. Five (14.7%) recurred and were treated with trephination + debridement-2 or wound care alone-3. Symptom length had no correlation with resolution time, skin type, hair amount. CONCLUSIONS: Standardized minimally invasive protocol requiring only selective surgical intervention can treat refractory pilonidal disease with low recurrence rate.
