    Abstract:
    The treatment of Crohn's disease is still a debatable issue especially as regards the integrated implementation of medical and surgical therapy, the timing of surgery and the choice of surgical technique. Prognostic factors seem to be important in the choice and planning of therapeutic procedures. The authors retrospectively review 81 patients, 31 of whom submitted to surgery. The parameters observed were the presenting symptoms, the time from onset of symptoms to surgery, previous medical treatment, disease location, and complications. Bowel resection and the treatment of fistulas and abscesses were carried out. Emergency resections were performed in 14 patients (45%): 11 for bowel obstruction, 2 for perforation and 1 for bleeding. The mean follow-up (which included laboratory tests and endoscopy) was 132 months (range: 6 months to 32 years). In-hospital mortality was 2.3% and morbidity 12.9%. Long-term mortality amounted to 3 patients, only 1 of whom died of complications related to recurrence of the disease. Statistical analysis showed that the recurrence rate was 51.3% at 5 years after the first surgical treatment, 65.4% at 10 years and 88.1% at 20 years. Recurrences requiring surgery amounted to 15.3%, 20.5% and 42.5%, respectively. No statistically significant correlations were observed between recurrence rate and time of onset of the disease (p = 0.5601), time of the first surgical treatment, disease location, or specific medical therapy, (p = n.s.). Recurrence requiring surgical treatment was observed in 33.3% of patients when the disease was located only in the ileum, in 33.3% when it was located in both the ileum and colon, and in 28.6% when only the colon was involved (p = 0.9767). The quality of life was good in 66.6% of patients, fair in 26.6%, and poor in 6.6%. The authors conclude that the treatment of Crohn's disease must be multidisciplinary and surgery must be limited to complications. When surgery is indicated, it must be performed promptly, because, in these cases, persisting with medical treatment increases the postoperative morbidity. Short resections must be performed in order to preserve the bowel as much as possible. As far as risk factors are concerned, the most important are the location and the aggressiveness of the disease, whilst biological and laboratory parameters do not seem to influence the results.
