title: Recurrent pilonidal sinus after excision with closed or open treatment: final result of a randomised trial.
abstract: 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.
  
  
  METHODS
  Randomised trial.
  
  
  METHODS
  Teaching hospital, Norway.
  
  
  METHODS
  120 Patients treated between 1987 and 1989.
  
  
  METHODS
  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).
  
  
  CONCLUSIONS
  Excision and primary suture compares favourably with open excision and healing by second intention in the treatment of chronic pilonidal sinus.
