Sacrococcygeal pilonidal sinus treated by a new fascio-cutaneous flap.

Purpose: This study reported the technical details and preliminary clinical outcomes of a new fascio-cutaneous transposition flap for the surgical treatment of pilonidal sinus.

Methods: Fifty-two patients with pilonidal sinus were surgically treated. During the surgical procedure, an inferiorly pedicled, fascio-cutaneous flap with specific geometric characteristics was prepared and transposed. Postoperative pain, complications, duration of hospital stay, and time off worked were assessed. Patients were followed for eighteen months after surgery.

Results: The mean hospital stay was 2 days. Drains and sutures were removed after 3 and 12 days, respectively. No flap ischemia, wound dehiscence or major complications were observed. Tension on suture lines and pain after surgery were negligible. Wound infections occurred in 4 patients (7.7 percent) and were managed by removing a few sutures. Seroma was detected in 6 patients (11.5 percent). The mean time patients missed work was 7 days. No recurrence was observed during the follow-up period of 18 months.

Conclusions: With no disease recurrence, minimal complication rate, time off work, and acceptable aesthetic outcome, this fascio-cutaneous transposition flap technique is a safe and effective method for surgically treating pilonidal sinus.
