Outcomes in the repair of pilonidal sinus disease excision wounds using a parasacral perforator flap.

Introduction: The ideal treatment for pilonidal sinus disease has yet to be defined. There are many approaches described in the literature.

Methods: Thirty-five consecutive patients who underwent wide excision of pilonidal sinus disease had the wound repaired using a parasacral perforator flap. Outcomes were assessed by case notes analysis and follow-up telephone and postal questionnaires.

Results: There were ten minor complications including six minor wound edge dehiscences. There were two ischaemic complications, with one flap loss. There were 3 recurrences of pilonidal disease at a mean follow-up of 33 months, giving a 5-year recurrence free rate of 86%. Of the patients questioned, all would recommend the procedure to someone else despite 69% being dissatisfied with the cosmetic outcome.

Conclusions: This series indicates that the parasacral perforator flap technique is able to repair pilonidal sinus excision wounds successfully with minimal morbidity and a low recurrence rate at a mean of follow-up of 33 months. The study suggests that it may be a technique best reserved for recurrent cases of pilonidal sinus disease. Patients feel the procedure is successful despite reservations regarding the cosmetic outcome.
