[Duodenal bile acid output in gastroenterologic diseases]

The biliary secretion of bile acids was measured with the modified secretin-pancreozymin test in 50 patients with various gastroenterological diseases and in a control group. In the control group the highest bile acid output and the lowest G/T quotient was estimated. In comparison to the control group, the bile acid output in the patients with gastroenterological disorders was reduced significantly to a varying degree. Except in postcholecystectomy patients, it was proved that the G/T quotient was significantly increased compared to that in the control group. The estimation of bile acid output and the G/T quotient presented here shows an easier extension of the validity of the secretin-pancreozymin test which does not indice any additional burden to the patients.
