title: Endoscopic pilonidal sinus treatment in the Asian population.
abstract: BACKGROUND
  This study aims to evaluate the early results of endoscopic pilonidal sinus treatment (EPSiT) in the Asian population and illustrate the surgical technique and its modifications by a video presentation (Supplemental Digital Content 1, http://links.lww.com/SLE/A115).
  
  
  METHODS
  Retrospective review of 9 patients with pilonidal sinus disease treated with EPSiT is performed in a single institution. Surgical outcomes of sinus healing, pain, and discharge were reviewed in the outpatient clinic and patient satisfaction levels were assessed through a standardized phone interview.
  
  
  RESULTS
  The median age was 24 years (range, 16 to 41 y). The median duration of follow-up was 2.5 months (range, 1 to 5 mo). Median duration of sinus healing is 6 weeks (range, 2 to 7 wk). One patient had pain despite sinus healing. Satisfaction rate was 78% (7/9).
  
  
  CONCLUSIONS
  EPSiT is a minimally invasive and cosmetically favorable procedure. A larger sample size and a longer follow-up is required to determine if it improves healing time and long-term recurrence rate.
