Is Wide Local Excision for Pilonidal Disease Still Justified?

Abstract

There is an ongoing debate regarding the optimal operation for chronic pilonidal disease. The current study analyzes the outcome of wide local excision (WLE) compared with unroofing and marsupialization (UM) as primary intervention for chronic pilonidal disease. A retrospective review of a single institution experience over a 5-year period was performed. Sixty-eight patients were treated for pilonidal disease. Their mean age was 25 years. There were 42 males (62%) and 26 females (38%). Twenty-six patients underwent WLE and 42 had UM. The type of operation was based on surgeon preference, but individual surgeons were consistent with their choice. Mean time for final healing was significantly higher for WLE compared with UM (21 vs 6 weeks, P < 0.01). Postoperative complications and reoperative rate were significantly higher in the WLE group ( P < 0.01). Nine patients in the WLE group (35%) required one or more reoperations compared with only one (2%) in the UM group ( P < 0.01). This study demonstrates that WLE carries a high complication and reoperative rate. UM should be considered as the initial operation for most patients with pilonidal disease.
