Background: Treatment of pilonidal sinus involves the use of various surgical procedures, most of which are associated with many complications and problems. Meanwhile, open and closed surgical procedures are two common surgical procedures for the treatment of patients with pilonidal sinus disease. The aim of this study is to compare the outcomes of open and closed surgical procedures in pilonidal cysts excision. Methods: This study was a randomized clinical trial that was performed on patients with pilonidal sinus referred to Shahid Beheshti Hospital of Yasuj University of Medical Sciences, Yasuj, Iran. Patients having inclusion criteria were assigned to 2 groups; first group for open surgical procedure (n:30) and second group for closed surgical procedure (n:30) using a simple randomized method. The data gathering tools were a demographic data form and a visual analog scale (VAS). Two types of open and closed surgery procedures were performed randomly on patients. Data were analyzed by SPSS-16 software using mean, standard deviation, independent t-test, Chi-square or Fisher exact test. Results: The results showed that the outcomes of recurrence of the disease (P = 0.001), wound infection (P = 0.003), and duration of surgery (P = 0.001) in open surgical procedure were significantly lower than the closed surgical procedure. Conclusions: Considering the better outcomes of open surgical procedure in terms of patient satisfaction after surgery and lower additional costs, the open surgical procedure is suggested for the treatment of pilonidal sinus - if one of these two methods should be selected by the surgeon.
