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.
