title: Impact of perineal pseudocontinent colostomy on perineal wound healing after abdominoperineal resection.
abstract: BACKGROUND
  Abdominoperineal resections (APR) for anorectal tumors are associated with a high rate of perineal wound complications. The aim of this study was to evaluate the impact of pseudocontinent perineal colostomy (PPC) following APR on perineal wound healing.
  
  
  METHODS
  All patients undergoing APR between 2000 and 2009 were retrospectively reviewed. Perineal wound healing was compared between patients with PPC and those with perineal closure alone.
  
  
  RESULTS
  APR was performed in 132 patients, including 31 with PPC and 101 with no PPC. Risk factors such as radiotherapy, smoking, diabetes mellitus, and obesity were not different between the two groups. The PPC group had significantly fewer cases of omentoplasty and adenocarcinoma histology. The overall perineal complication rate, perineal infection, or wound dehiscence was similar in the two groups, but the perineal healing rate at 6 and 12 weeks was significantly increased in the PPC group than in the non-PPC group (70.9% vs. 50%, P = 0.04, at 6 weeks; 90.3% vs. 73%, P = 0.04, at 12 weeks).
  
  
  CONCLUSIONS
  PPC accelerates perineal wound healing after APR without decreasing the overall perineal complication rate.
