Long-term effects on diet after proctocolectomy for ulcerative colitis.
BACKGROUND
Patients with ulcerative colitis (UC) often report dietary intolerances. Our aim was to assess the effects of proctocolectomy (PC) for UC on dietary intolerances.


METHODS
A novel disease-specific questionnaire was used.


RESULTS
Eighty-seven percent of patients reported 338 dietary intolerances. Of 225 preoperative dietary intolerances, 151 (67%) resolved/improved, 56 (25%) were unchanged, and 18 (8%) were exacerbated after PC. A total of 113 dietary intolerances developed only after PC. The incidence of specific dietary intolerances in patients 10 years and older post-PC was similar to patients younger than 10 years post-PC except for a lower incidence of caffeinated beverage (P = .01) dietary intolerances 10 years or more post-PC. Intestinal symptoms, bowel function, and activities of daily living largely improved after PC. Extraintestinal UC symptoms worsened or failed to improve in 74%.


CONCLUSIONS
PC for UC frequently improves preoperative dietary intolerances. Some patients, however, are at risk for onset of new dietary intolerances after PC. Studies examining traditional symptoms in UC patients pre-PC and post-PC may be enhanced by examining effects on specific dietary intolerances.
