Bilateral gluteal advancement flap for treatment of recurrent sacrococcygeal pilonidal disease: A prospective cohort study

Abstract Background There is controversy about the best surgical approach for recurrent pilonidal disease (PND) up till now. This study aims to evaluate the efficacy of bilateral gluteal fascio-myo-cutaneous advancement flap (BGFMCF) in treatment of recurrent PND. Patient and methods Forty patients (35 males, 5 females) with recurrent PND were admitted and treated with BGFMCF. Variables assessed were incidence of recurrence, postoperative complications, patients' satisfaction and quality of life. Results Patients had a mean age of 25 ± 6.8 years and a mean body mass index of 28.4 ± 2.7. Mean operative time was 87 ± 13 min and mean length of hospital stay was 3 ± 0.7 days. Mean period of follow-up was 15.8 ± 4.9 months. Recurrence was detected in 2 (5%) patients and minor complications occurred in 6 (15%) patients. Thirty eight (95%) patients were satisfied by the procedure at the end of follow-up period. Conclusion BGFMCF is an effective procedure for treatment of recurrent sacrococcygeal PND with low recurrence rate and acceptable morbidity.
