title: Comparison of modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle in the treatment of pilonidal sinus disease.
abstract: BACKGROUND
  Although many options exist for surgical treatment of pilonidal sinus disease (PSD), consensus has not yet been achieved, as all surgical methods have various rates of complications, postoperative infection, and recurrence.
  
  
  METHODS
  This study was a prospective, randomized, clinical trial, and was conducted with consecutive 100 patients admitted to Ankara Military Hospital General Surgery Service for treatment of PSD from May 2013 to August 2013. This study compared two surgical treatments for PSD: modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle. The patients received surgical treatment with either modified Limberg flap transposition (n = 50) or lateral advancement flap transposition with Burow's triangle (n = 50). Clinical healing period, length of hospital stay, operative time, postoperative complications including recurrence, wound dehiscence, and surgical site infection, as noted during postoperative follow-up period; Visual Analog Scale scores for pain.
  
  
  RESULTS
  The mean follow-up period was 12 months. No significant differences were observed between the 2 groups in length of hospital stay (P = .515), operative time (P = .175), wound dehiscence (P = .645), and Visual Analog Scale pain scores (P = .112). The mean operative times were 42.5 minutes in the modified Limberg group and 40.0 minutes in the lateral advancement group.
  
  
  CONCLUSIONS
  Although lateral advancement flap transposition with Burow's triangle is used less often than modified Limberg flap transposition, we could not determine a parameter that was statistically different such as operative time, postoperative complication, or the length of hospital stay. Hence, the lateral advancement flap is as viable an option as other more preferable techniques in the treatment of PSD, which particularly settled on the upper segment without a deep natal cleft.
