Abstract
To evaluate possible risk factors for recurrence after primary resection of ileocolic Crohn's disease, the clinical course of 48 consecutive patients operated on over a 27-year period were reviewed. Median follow-up was 10 years (range, 3-27 years). The probability of not having a recurrence and the probability of not undergoing a second resection were 0.476 (±0.191, 95% confidence limits) and 0.701 (±0.180), respectively, after 10 years. None of the possible risk factors examined—sex, age at the primary resection, length of preoperative history, length of bowel involvement, failure of preoperative medical treatment, and residual microscopic disease at resections lines—significantly influenced the risk of recurrent disease (P > 0.05, log-rank test); however, there was a trend towards a higher risk of recurrence for the patients who had received medical treatment preoperatively. In the present study it was not possible to identify any factors that influenced the risk of recurrence.
