Pilonidal sinus, Recurrence, Excision, Limberg flap


Background: Pilonidal sinus is a common anorectal condition affecting young adults with various etiological factors. Various surgical methods have been described, but treatment failure and recurrence are frequent, causing considerable morbidity. This study was undertaken to study the different surgical methods in treatment of pilonidal sinus.

Methods: This study was done between January 2017 and June 2018. 20 cases underwent excision with open healing and 10 cases underwent excision with primary closure. The surgeries for primary closure included Limberg flap, Karydakis technique and Z plasty. Patients were analyzed with respect to post operative complications, duration of hospital stay, duration of getting back to work and duration of wound healing.

Results: Spectrum of clinical presentation included pain, discharge, sinus and swelling. No recurrences were observed in the present study. Wound infection occurred in only three cases. Duration of wound healing was found to be an average of 51.6 days in Excision with open healing method and 14.2 days in excision with primary closure method. The average length of hospital stay in excision and lay open group was 4.35 days and 5.4 days in the excision and primary closure group. The average duration to return to work was 34 days in excision and lay open group, while it was 8 days in excision and primary closure group.

Conclusions: Excision with primary closure is a better modality than excision with lay open technique in treatment of pilonidal sinus.
