title: Gallstone prevalence and biliary lipid composition in inflammatory bowel disease.
abstract: Biliary cholesterol saturation has been correlated with disease variables that might effect bile acid loss in ileitis patients with (N = 9) or without (N = 8) intestinal resection having a defined prevalence of gallstones. In addition, cholesterol saturation was determined in ulcerative colitis patients (N = 7) and gallstone patients (N = 18) as well as in 5 normal controls. Biliary cholesterol saturation in ileitis patients both with and without resection was similar to that in gallstone patients yet the prevalence of gallstones was only 12%. Cholesterol saturation did not correlate with ileal resection nor the extent, duration, or activity of ileitis. Biliary cholesterol saturation was not different in ulcerative colitis patients from that in normal subjects. It is concluded that cholesterol saturation of bile alone does not account for the high prevalence of cholesterol gallstones that has been reported in ileitis patients.
