Clinical analysis of excision and primary suture and Limberg transposition flap for the treatment of pilonidal sinus

Abstract

Objective To compare the clinical therapeutic efficacy of excision and primary suture after the hydrogen peroxide and methylene blue treatment, and Limberg transposition flap for the treatment of pilonidal sinus. Methods The clinical data of 55 patients with sacrococcygeal pilonidal sinus were analyzed retrospectively. Thirty-six patients were treated by excision and primary suture after the hydrogen peroxide and methylene blue treatment (suture group), and 19 patients were treated by Limberg transposition flap (flap group). The operation time, length of hospital stay, incision healing time, incidence of complications and recurrence rate were compared between 2 groups. Results There were no significant differences in the length of hospital stay, incision healing time, incidence of complications and recurrence rate between 2 groups (P >0.05). The operation time in suture group was significantly shorter than that in flap group: (51.25 ± 7.02) min vs. (71.42 ± 12.29) min, and there was statistical difference (P = 0.000). Conclusions Excision and primary suture after the hydrogen peroxide and methylene blue treatment is a good method for the treatment of pilonidal sinus. The operation time is short. It is easy to operate, and could achieve good results. Key words: Pilonidal sinus; Hydrogen peroxide; Methylene blue; Retrospective studies
