799 Negative Pressure Wound Therapy Following Excision of Pilonidal Sinus Disease: A Retrospective Review

Abstract

Abstract Background Pilonidal sinus disease (PSD) is a common condition that can have a detrimental impact on patient quality of life. Definitive surgical management for PSD is challenging and remains a contentious issue. Primary closure is associated with a high recurrence rate, while healing by secondary intention comes with slow healing and burdensome wound care. Negative pressure wound therapy (NPWT) is widely used to accelerate healing. Aim To evaluate outcomes in patients with PSD treated by a standardised technique of complete surgical excision followed by the application of NPWT. Method A retrospective observational cohort study of all patients with PSD managed by complete surgical excision followed by application of NPWT was performed over a 5-year period. Results 41 patients underwent excision of PSD with application of NPWT during the observation period. All patients’ wounds healed successfully with NPWT. Only one patient (2.4%) developed recurrent PSD and required further surgery. Discussion The ideal surgery for PSD should have a low recurrence rate. Our results demonstrate that our technique of complete surgical excision followed by application of NPWT meets all these criteria. To our knowledge, this study contains the largest number of patients with PSD managed by excision and NPWT in the literature.
