ABSTRACT
OBJECTIVE: A retrospective analysis of patients undergoing surgery for complex (> or =3 tracks) or recurrent pilonidal sinus (PS) was performed; the results of this clinical experience were compared with an original method of primary wound closure, coupling a "tension-free" technique of wound reconstruction with autologous cryoplatelet gel application, in order to improve the wound healing process and reduce the postoperative disability period. PATIENTS AND METHODS: The retrospective analysis included 30 patients undergoing surgery for PS between January 2003 and May 2005: in the first group of 15 consecutive patients, the wound was left open to close secondarily while in the remaining 15 patients, primary closure by means of a "tension-free" technique of wound reconstruction was attempted. Between June 2005 and May 2006, another subset of 15 patients was prospectively recruited, coupling the "tension-free" technique of wound reconstruction with autologous cryoplatelet gel application. RESULTS: In the first group of patients, median postoperative disability accounted for 65 days with one recurrence. In the second group, primary healing was achieved in 11 patients, with a median postoperative disability of 28 days; two recurrences did occur. In the third group of patients, primary healing was achieved in all patients within 14 to 29 days, and no recurrence has yet been detected. CONCLUSION: Short follow-up notwithstanding, the simplicity of the operation, the use of autologous products and the minimal postoperative disability with complete wound healing suggest that this new approach may represent a useful alternative to current surgical techniques for PS excision.
