title: [The frequency of relapse in operated and non-operated Crohn's disease. Conclusions for the indications for surgery].
abstract: 162 patients with Crohn's disease were followed up for an average of 9.1 years. 91 patients underwent surgery. In our series 60% relapses were noted in patients in whom the interval between surgery and reevaluation was at least 3 years. 19.8% of the 71 patients who did not undergo surgery had relapses. The following conclusions are drawn: 1. The operation has a curative effect in only a few cases. 2. The operation is indicated only in the event of complications. 3. Relapses following appropriate surgery are not due to the operation but are a sign of activity of the disease.
