Oblique excision with primary closure for the treatment of pilonidal sinus

Although pilonidal disease of the sacrococcygeal region is common, controversy still exists regarding its treatment. The goal of treatment should be to pre vent recurrence while minimizing the patient's postoperative pain and disability. During a two-year period, 32 consecutive patients (Group A) were treated for chronic pilonidal disease by oblique excision and primary closure. The results were compared with 45 patients (Group B) who had been treated by vertical excision and primary closure. Patients with acute pilonidal abscess or recurrent pilonidal disease were excluded from the study. The mean follow-up was 15.9 months for Group A and 19.6 months for Group B. The average length of hospital stay and time for return to daily activities were 3.18+/-1.31 vs. 5.53+/-4.11 days and 10.4+/-14.37 vs. 12.91+/-39.17 days in Groups A and B, respectively (p<0.001 and p<0.01). The overall recurrence rate was 35.5% in Group B whereas there were no recurrences in Group A. On the basis of our current experience, oblique excision with primary closure achieves the most promising treatment of this condition.
