Outcome of chronic pilonidal disease treatment after ambulatory plain midline excision and primary suture.
BACKGROUND
Pilonidal sinus (PS) is a common chronic disorder of the sacrococcygeal region. The optimal treatment for PS remains controversial, and recent reports have advocated different surgical approaches.


METHODS
A prospective study was performed on 103 patients with nonrecurrent quiescent chronic discharging sinus. Excision with primary closure was performed on all patients. Patients were subdivided randomly into 2 groups. In group A, the excision was associated with drainage of the wound; in group B, the wound was not drained.


RESULTS
Excision with primary closure and drainage was performed in 53 patients (group A). Drainage was omitted in 50 patients (group B). Minor wound complications occurred in 3 patients in group A and in 36 patients in group B. No complete dehiscence of the wound was observed in patients in group A and in 8 patients in group B. Complete healing was fastest in patients in group A. Sinus recurrence occurred in 1 patient in group A and in 2 patients in group B.


CONCLUSIONS
Short- and long-term results suggest that limited midline excision with primary closure and wound drainage is a simple and effective procedure in the surgical treatment of uncomplicated PS. More demanding flap techniques and plasties should be reserved for complicated PS, which requires a wider excision.
