Treatment of haemorrhoids in patients with inflammatory bowel disease.

A retrospective review of outcome was undertaken in forty-two patients with ulcerative colitis and twenty patients with Crohn's disease who were treated for haemorrhoids and the inflammatory bowel disease between 1935 and 1975. Both surgical and conservative treatment of haemorrhoids in patients with ulcerative colitis had low complication-rates (4 complications after 58 courses of treatment). In Crohn's disease the complication-rate was high (11 complications after 26 courses of treatment). One of the forty-two patients with ulcerative colitis and six of the twenty with Crohn's disease required rectal excision for complications apparently dating from the treatment of haemorrhoids. These results suggest that treatment of symptomatic haemorrhoids is usually safe in patients with ulcerative colitis but is contraindicated in those with Crohn's disease.
