Surgical recurrence of perforating and nonperforating Crohn's disease

The cumulative probability of requiring a reoperation for patients undergoing surgery for the P type of Crohn's disease is significantly different from that of patients with NP indications. The risk of having to undergo further surgery is particularly high during the first two years following an operation for perforating disease. The concept of a relatively aggressive perforating type of Crohn's disease and a more indolent nonperforating type is confirmed by the results of this study.
