title: Selected operative management of fistula-in-ano in Crohn's disease.
abstract: OBJECTIVE
  The operative management of patients with fistula-in-ano in the presence of Crohn's disease has been controversial. Our aim was to review the results of operative treatment in this clinical setting.
  
  
  METHODS
  Twenty-eight such patients treated between 1976 and 1990 were reviewed. The duration of local symptoms, location of the Crohn's disease, medications, and previous operations were noted. An effort was made to classify the fistula-in-ano according to Parks' classification, but many fistulas were complicated and did not neatly fit into one of the described categories (intersphincteric 9, transsphincteric 10, complex 9). Patients underwent fistulotomy (three with a seton).
  
  
  RESULTS
  Complete healing was achieved in 71.4 percent of cases with an average healing time of 3.5 months (range, 3 weeks-26 months). With an average follow-up of 71 months (range, 12 months-14 years), postoperative function was good in 20 (71.5 percent) patients. Of the remaining eight patients, five ultimately underwent total proctocolectomy because of the severity of their colorectal disease, one patient developed alteration of continence, and two patients developed stenosis. There were two recurrences, (one at nine months and one at six years).
  
  
  CONCLUSIONS
  Operative treatment should be offered to selected patients with fistula-in-ano in the presence of Crohn's disease.
