Surgical treatment of pilonidal disease - Short-term follow up results of minimally invasive pit-picking surgery versus radical excision without suturing: A prospective randomised trial

Abstract

BackgroundIn this study we compared the potential benefits of surgical treatments for chronic symptomatic pilonidal disease (PD) - minimally invasive pit-picking surgery and radical excision without wound suturing. Materials and methodsA total of 100 adult patients with chronic symptomatic PD were enrolled in this study at the Kaunas Hospital of the Lithuanian University of Health Sciences. They were randomly divided into two groups: pit-picking surgery (n = 50) and radical excision with open healing (n = 50). Recurrent PD patients were not excluded. The comparison of the techniques was based on pain within the first postoperative week, failed surgery rates, and wound healing time. Additionally, pain levels at different time intervals following the treatment, analgesic consumption, and time off work, were assessed and compared. ResultsA total of 89 patients (89 %) were available for follow-up after 6 months. Pain levels the first postoperative week were significantly lower in the pit-picking group compared to the radical excision group, with median scores of 10.0 and 20.0, respectively (p = 0.002). The complete wound healing time was longer in the radical excision group (60 days) versus the pit-picking group (17 days), with a significant difference noted (p = 0.00). No significant difference was observed between the type of surgery and the rate of failed surgery, with 5 (11.9 %) cases in the pit-picking group and 4 (8.5 %) in the radical excision group. ConclusionBased on our short-term findings, minimally invasive pit-picking surgery is a better option regarding pain, wound healing time and failed surgery rate. In cases where this approach is not suitable, other alternatives should be contemplated, as radical surgery without wound suturing should not be employed as a treatment method for PD. Additionally, the relationship between PD and recurrence rates should be investigated further.
