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

• 40 patients with recurrent PND were treated with bilateral gluteal advancement flap.
• Patients had a mean age of 25.1 ± 6.8 years and mean BMI of 28.4 ± 2.7.
• Mean operative time was 87 ± 13 min. Mean LOS was 3 ± 0.72 days.
• Recurrence occurred in 2 patients and minor complications in 6 patients.
• 38 patients were satisfied by the end of follow-up period.

BackgroundThere 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 methodsForty 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.ResultsPatients 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.ConclusionBGFMCF is an effective procedure for treatment of recurrent sacrococcygeal PND with low recurrence rate and acceptable morbidity.
