Recurrence after operation for Crohn's disease:

B. Is usually found just proximal to an enteric anastomosis.

DISCUSSION: Recurrence after operation for Crohn's disease often occurs just proximal to an enteric anastomosis or stoma and occurs at a rate of about 6% per year over the first 10 years after operation. Recurrence follows operations for both ileal and colonic Crohn's and is not prevented by medical therapy using corticosteroids. Reoperation is required for 30% to 50% of subjects at risk.
