Excision with primary closure and suction drainage for pilonidal sinus in adolescent patients

Controversy persists regarding the treatment of pilonidal sinus (PS). To evaluate the efficacy of excision with primary closure and closed-suction drainage in adolescent patients, between 1990 and 1999, 34 consecutive patients aged 13-18 years (mean 16.4) underwent PS excision with primary closure and suction drainage. Anesthesia was general in 16 (47%) and spinal in 18 (53%) with a statistical age difference (P< 0.001) (15.5 vs 17.2 years, respectively). No complications due to the anesthetic were observed. Twenty-one patients (61.8%) had day-case surgery while the others were hospitalized for 2 to 4 days (average 2.3 days). The drain was removed on postoperative day 2 to 6 (average 2.2). Primary healing with no postoperative complications occurred in 30 patients (88.2%); 1 underwent partial opening of the wound because of rupture of the drainage tube during its removal. Postoperative infections requiring incision, drainage, and lay-open occurred in 3 cases (9.1%). No recurrence was found at 12-month follow-up. One recurrence (2.9%) was noted 3 years after surgery. Excision with primary closure and closedsuction drainage as an ambulatory procedure is thus a simple and effective method of treatment of uncomplicated PS in adolescents.
