[Determination of bile acids in stools of patients with colonic neoplasms and adenomatous polyps].

Since several years ago, the biliar acids have been incriminated in the etiopathogeny of colon cancer and adenomatous polyps, above all the secondary ones, involved by its aggressive action over the colonic epithelium in these mechanisms. The dietetical habits of developed countries have the high responsibility for this situation, their food pattern being a high animal fat diet, high in refined carbohydrates, animal proteins and low in dietetic fiber (diet type "occidental") unlike to developing countries that have a high natural fiber diet, having a much lower incidence in colon cancer and adenomatous polyps. Dietetic fiber has been studied considering it with a protector effect over the aggressive action of biliar acids on the colon mucous. We have studied 60 patients, 20 of them with colon cancer, 20 with adenomatous and 20 case controls without colonic pathology. All of them had total high biliar acids in stools, a dietetical screening was carried out to determine the intake of animal fat and dietetic fibre during a week. There was a significant correlation in cases of cancer, polyps and biliar acids high in stools. There was also a significant correlation between the undue dietetic habits in colon cancer patients and high bilar acids. In those cases of adenomatous polyps, there was not a significant relation to dietetic habits.
