Outcome of Dufourmental Flap in the Management of Complex Pilonidal Sinus

Background: There are numerous surgical and non-surgical therapy options for pilonidal sinus disease (PSD) with varying degrees of efficacy. Objectives: This study aimed to evaluate the outcome of Dufourmental flap in complex pilonidal diseases. Patients and methods: The study included 34 patients with complex and recurrent pilonidal sinus eligible for surgical excision and reconstruction using the dufourmental flap. Follow-up was planned for 12 months to document the postoperative complications and the aesthetic outcome. Results: The patients’ mean age was 28.4 ± 3.6 years. The main clinical presentation was discharge in 44.1% of patients. The mean operative time was 41.6 ± 9.4 minutes. The Mean VAS showed a gradual decrease from 7.6 ± 1.6 immediately postoperatively to 2.1 ± 0.5 after one week. Seroma was reported in 5.9% of patients, while wound dehiscence occurred in 11.75% of patients. No total flap loss was reported, while partial flap loss was reported in 5.9% of cases. No reported cases of recurrence after 1-year follow-up. There was a strong positive correlation between patients’ evaluation and independent surgeons’ assessment (r=0.86). Conclusion: The Dufourmental flap can be considered as an appropriate approach in managing complex pilonidal disease
