title: Effects of Incisional Negative-Pressure Wound Therapy on Primary Closed Defects after Superficial Circumflex Iliac Artery Perforator Flap Harvest: Randomized Controlled Study.
abstract: BACKGROUND
  Prolonged hematoma or seroma after primary closure is a causative element in wound complications. This study evaluated the effects of negative-pressure wound therapy on primary closed wounds after superficial circumflex iliac artery perforator flap harvest.
  
  
  METHODS
  This study was a prospective, randomized, clinical trial comparing conventional dressing against a single application of negative-pressure wound therapy for 5 days after primary closure. A total of 100 patients who had superficial circumflex iliac artery perforator flap harvest were enrolled.
  
  
  RESULTS
  There was no statistical difference between the incisional negative-pressure wound therapy and conventional dressing groups in the distribution of risk factors. Significant findings were noted for duration and amount of closed suction drainage: 6.12 ± 4.99 days (median, 4 days; range, 3 to 8 days) and 100.47 ± 140.69 cc (median, 42 cc) for wounds treated with conventional dressing versus 3.34 ± 1.35 days (median, 3 days; range, 2 to 4 days) and 23.28 ±18.36 cc (median, 20 cc) for wounds in treatment group (p = 0.0077 and p = 0.0004), respectively. After closure, an increase in skin perfusion were noted on day 5 in the treatment group (p = 0.0223). There was one case of wound dehiscence in the conventional dressing group.
  
  
  CONCLUSIONS
  The incisional negative-pressure wound therapy has a positive effect over primary closed surgical defects by significantly reducing the amount of fluid collected by closed suction drains, allowing earlier removal of drains and enhancing the skin perfusion on the repaired skin.
