The prevalence of gallstones has been examined in an unselected group of ileostomy patients who had undergone surgery for ulcerative colitis. In this group 11 of 55 patients were found to have gallbladder disease which is an overall incidence of 20%. This is considerably higher than that found in a control population in the same area.
