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.A retrospective survey included 59 patients with perianal Crohn's disease who had undergone surgery during the period of 1991 to 1993, inclusive.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.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.
