title: [Effect of closed high-pressure suction drainage on primary healing of perineal wound after abdominoperineal resection for rectal cancer].
abstract: OBJECTIVE
  To evaluate the impact of closed high-pressure suction drainage on the healing of the perineal wound after abdominoperineal resection.
  
  
  METHODS
  Patients undergoing rectal abdominoperineal resection in the Wuhan Tongji Hospital from January 2009 to January 2011 were randomized into two groups including the study group(n=61, closed high-pressure suction drainage) and the control group(n=59, presacral drainage). The drainage volume, primary healing rate, and the healing time of perineal wounds were compared.
  
  
  RESULTS
  The total volume of the drainage in the first 3 days was (448.1±142.9) ml in the study group and (548.3±190.6) ml in the control group, the volume of the drainage on the third day was (28.1±12.7) ml and (125.9±84.3) ml respectively. The primary healing rate was 93.4%(57/61) in the study group and 74.6% (44/59) in the control group, the healing time was (13.5±3.5) days and (20.1±5.1) days respectively.
  
  
  CONCLUSIONS
  Closed high-pressure suction drainage may promote perineal wound healing following rectal abdominoperineal resection.
