Résumé
<p><b>OBJECTIVE</b>To investigate the surgical treatment of Crohn disease(CD) complicated with perforation or fistula.</p><p><b>METHODS</b>The clinical data of 24 CD cases complicated with perforation or fistula treated in our department from Jan. 1980 to Apr. 2005 were analyzed retrospectively.</p><p><b>RESULTS</b>There were 24 cases of CD complicated with perforation or fistula among 181 CD patients,and the incidence of perforation or fistula was 13.3%. Steroid treatment before perforation was given in 8 patients, while not in 9 patients and unclear in 7 patients. Eighteen patients had single perforation, 4 patients two free perforations and 2 patients more than three extra-abdominal fistula. Emergency operation was performed in 8 cases and selective operation in 16 cases. Five cases had postoperative complications including incision infection in 2, intra-abdominal abscess in 2 and stomal fistula in one case, and were all cured by surgical drainage and anti-infection treatment. The morbidity rate was 20.8%. The postoperative mortality rate was 12.5% (3/24). Eighteen patients were followed up from 6 months to 18 years, and the 5-year recurrent rate was 16.7%. The 10-year reoperation rate was 33.3%.</p><p><b>CONCLUSIONS</b>Steroid use is not the main cause of perforation or fistula in CD. Perforation or fistula is the definite indication for surgical treatment.</p>
