Perianal Crohn's disease—Is it all bad news?

Abstract

Perianal Crohn's disease does not inevitably lead to panproctocolectomy. Cautious surgery for fistula when rectal inflammation is quiescent is worthwhile. Loss of bowel continuity is more likely when colitis coexists with perianal disease. Panproctocolectomy is often indicated because of the combination of colitis and perianal disease rather than for perianal disease alone.
