A simple method for total faecal bile acid (FBA) determination was carried out. This test involves a 72 hour stool collection, homogenization and FBA determination by means of an enzymatic-fluorimetric method (3 -Hydroxysteroid-dehydrogenase). The reliability of this test was discussed. FBA levels were tested in twelve healthy volunteers. In addition, two patients with bile acid malabsorption syndrome due to terminal ileitis and one patient with cholegenic diarrhoea caused by biliocolonic fistula were examined. The mean +/- SD of FBA values in healthy subjects was 0.49 +/- 0.3 g/72 hours. However, all patients tested show a marked increase of FBA levels. In conclusion the present method for bile acid determination in the faeces seems to be a useful tool in the diagnosis of bile acid malabsorption syndrome and in cholegenic diarrhoea.
