Abstract
We attempted to determine whether the administration of aspirin or ursodeoxycholic acid during loss of weight could prevent the development of lithogenic changes in bile and the formation of gallstones. Sixty-eight obese subjects without gallstones who were entered in a program (520 kcal per day) to lose weight were randomly assigned to receive ursodeoxycholic acid (1200 mg per day), aspirin (1300 mg per day), or placebo in double-blind fashion for up to 16 weeks. At entry, at four weeks of treatment, and at three weeks after the completion of treatment, the subjects underwent ultrasonography to detect gallstones and duodenal drainage of bile to detect cholesterol crystals and to determine the bile saturation index and glycoprotein concentration.
