Abstract
Background: Pilonidal disease is a chronic inflammatory disease of the sacrococcygeal region that mainly affects young people. Its incidence is 26 cases per 100,000 persons. Although many techniques have been described, there is no consensus on the treatment of pilonidal sinus disease (PSD). Materials and Methods: This study included 30 patients with PSD who were treated between May 2014 and September 2017. All cases underwent excision and flap reconstruction. The operative time, postoperative complications, the length of hospital stay, painless sitting and walking time, patient satisfaction and recurrence were evaluated prospectively. Results: The results of this prospective, randomized and comparative study are based on experience of a single surgical centre. All patients were followed up 18 months after discharge from the hospital. There is a difference in surgery durations (minutes) between the two groups (33.86 ± 2.89 min. in “keystone” flap vs. 41.26 ± 4.19 in the “rhombic” flap group) (p = 0.001). There were no significant differences in the length of hospital stay, painless sitting and walking time or patient satisfaction. The total complication rate was 66.6% after rhomboid flap compared with 6.6% after keystone flap. There was no flap necrosis. Conclusions: Both of these methods have shown to be successful in treatment of PSD. The KPIF is associated with the advantages of very simple design, abundant blood supply from the perforator vessels and lower rate of complication.

Summary
Pilonidal sinus disease is a common and acquired entity of young adults and has an estimated incidence of 26/100,000 in the general population [1] [2] It is seen more commonly in men than in women (male:female ratio 3 - 4:1) [3]. Several short- and long-term outcomes have been published comparing different methods of treatments in PSD Most of these studies compare Limberg rhomboid flap with other surgical or non-surgical techniques. The aim of the present study was to compare the short-term results of the management of sacrococcygeal PSD with the keystone flap vs the rhomboid flap (Limberg or Dufourmentel) in a randomized controlled trial as regards recurrence and complications rates, operative time, duration of hospital stay, time to walk without pain, time to sitting on toilet without pain, duration of the incapacity to work and cosmetic satisfaction of the patients. The KPIF is associated with the advantages of very simple design, abundant blood supply from the perforator vessels and lower rate of complication
