Introduction:
Pilonidal sinus (PS) is a highly frequent condition in teenagers. There is no consensus on which type of closure should be carried out following surgical removal. Our objective is to compare primary closure (PC) results with secondary closure (SC) or deferred closure results.
Materials And Methods:
Patients undergoing surgery for PS between 2013 and 2018 were studied and classified according to the type of closure. Presence of infection at removal, recurrence rate, pre- and postoperative antibiotic treat-ment, number of previous drainages, and sinus size were analyzed.
Results:
Of the 57 patients (29 of whom women), 29 were treated using PC and 28 using SC. Mean age was 14±1 years in the PC group, and 16±1 years in the SC group. PC patients presented a postoperative partial dehiscence rate of 26%. No statistically significant differences were found between groups regarding the presence of infection at surgery, recurrence rate, postoperative antibiotic treat-ment, number of previous drainages, and sinus size (p>0.05). The SC group re-quired more postoperative dressings [4 (0-6) vs. 8 (2-11) (p<0.01)] and longer time to healing [60 days (9-240) vs. 98 days (30-450) (p<0.01)].
Conclusions:
1 out of 4 PS patients with PC presents postoperative partial dehiscence. However, PC involves fewer subsequent dressings and shorter heal-ing times as compared to SC.
