Recurrence rate in the pilonidal sinus after excision with or without primary closure

Pilonidal sinuses typically occur in the sacrococcygeal skin of young adults and its treatment is surgery. The most common methods are excision with or without primary closure procedures. Considering that the recent researches have shown different results، we have compared the recurrence rate of pilonidal sinus using the 2 methods.

The study was studied on 250 patients، who had gone under pilonidal sinus surgery for the first time at least 5 months ago. Recurrence rate and signs of recovery were studied. Patients with experience a painful period until 5 months after the surgery were excluded. Finally، 123 patients with open surgery and 127 with closed surgery were included.

Recurrence rate was 9. 8% (12 cases) in open surgery and 11% (14 cases) in closed surgery. Probability of non- recurrence after 1،2 and 5 years were 99%، 95% and 91% after open surgery and 97%، 94% and 87% after closed surgery respectively. Type of surgery has no affect on pilonidal sinuses recurrence.

Findings showed that there was not significant difference in the recurrence rate of pilonidal sinus after excision between with and without primary closure procedures. Regarding to less complication، excision and primary closure، as a preferred procedure in the management of pilonidal sinus disease، is recommended.
