PurposeThis study was planned to evaluate prospectively the results of 112 pilonidal sinus cases treated surgically by using asymmetric excision and primary closure with suction drain and subcuticular skin closure. It is aimed at elimination of the causative factors of pilonidal sinus.MethodThe patient's age, profession, weight and height, symptoms and signs, duration of symptoms, previous treatments, operation time and cost, hospital stay, return to normal activity, complications, pathologic and microbiologic examinations, and recurrences were noted. All pilonidal sinus cases except pilonidal abscess and extensive gluteal involvement were treated surgically. The procedure consists of an eccentric, elliptical excision of the affected tissue, mobilization of the flap to the sacrococcygeal fascia and the suturing of its edge to the lateral one. Penrose drains were placed in the first eight (7.14 percent) cases, but suction drains were placed in others. The cases were followed up for a mean of 2.4 years.ResultsTwenty-eight (25 percent) cases had undergone previous operative procedures. Of 112 patients 106 (94.6 percent) were male. Mean age was 22.1 years. Mean history of disease was 4.2 years. The overall complication rate was 7.14 percent. Two (1.8 percent) wound infections, two wound breakdowns, three (2.7 percent) collections, and one (0.9 percent) recurrence were recorded. The collections were reduced to zero after first eight cases by using a suction drain. Sixty-eight of the patients (60.7 percent) had body weight over 90 kg, and the mean body mass index was 24.8. The mean hospital stay was 2.6 days, and the mean time off work was 12.4 days. The average healing time was 13.2 days. There were no anesthetic or surgical deaths.ConclusionThe natal cleft is flattened and the incision scar and the incision line is transferred from the midline to the lateral side by performing the asymmetric excision and primary closure, and thus the essential cause of pilonidal sinus is eliminated. The procedure is simple, the complications and recurrences are very low, and it is seen to be an excellent procedure in the surgical treatment of uncomplicated pilonidal sinus disease.
