Bile acid metabolism in ileostomy patients. 1977

K Huibregtse, and F Hoek, and G T Sanders, and G N Tytgat

In ten ileostomy patients, a 14C-cholylglycine breath test was performed. The 14CO2 in the exhaled air and the 14C bile acid quantity and composition and fat content in the subsequent 24 h ileostomy effluent were determined and compared to the values in twenty healthy controls. The results show that in ileostomy patients only minor bile acid-deconjugation occurs in vivo. Deconjugation in the ileostomy bags was found to be mainly responsible for the absence of conjugated bile acids in many of the ileostomy effluent samples. Secondary bile acids were not present in these patients, as determined by TLC. The fecal fat and bile acid excretion was found to be in the normal range in ileostomy patients provided no concomitant ileum resection was present.

This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.

D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
