1Department of Surgery, Rogaland Central Hospital, Stavanger, Norway.
Objective:
To find out the recurrence rate of chronic pilonidal sinus after excision and primary suture compared with open excision and healing by second intention.
Design:
Randomised trial.
Setting:
Teaching hospital, Norway.
Subjects:
120 Patients treated between 1987 and 1989.
Interventions:
60 Patients were treated by excision and primary suture and 60 by open excision. The median follow-up period was 4.2 years.
Results:
Recurrent pilonidal sinus was seen in six patients (10%) after primary suture compared with three patients (5%) after open treatment (p = 0.49); 57 (95%) and 55 (92%), respectively, were satisfied with the outcome of treatment at follow-up (p = 0.72).
Conclusion:
Excision and primary suture compares favourably with open excision and healing by second intention in the treatment of chronic pilonidal sinus.
