title: Evaluation of surgery for perianal Crohn's fistulas.
abstract: OBJECTIVE
  This study was designed to evaluate the operative treatments performed on patients with perianal Crohn's disease at a tertiary referral colorectal university hospital and to determine the efficacy of management by assessing patient satisfaction.
  
  
  METHODS
  A retrospective survey included 59 patients with perianal Crohn's disease who had undergone surgery during the period of 1991 to 1993, inclusive.
  
  
  RESULTS
  Twenty-seven patients were treated by laying the fistula open (81 percent successful), and another 27 cases were treated with a loose seton (85 percent successful). Five cases were complicated fistulas and underwent diversionary stomas as part of a primary procedure. Overall success rate, as judged by patient satisfaction, was 83 percent.
  
  
  CONCLUSIONS
  Conservative surgery has a role in management of perianal Crohn's disease. Patient satisfaction can be achieved without complete healing. Better preoperative assessment may improve results further.
