Inorganic phosphorus in human bile.
The inorganic phosphorus concentration has been measured in fresh bile from patients undergoing cholecystectomy, usually because of cholelithiasis. The amount in common duct bile for patients with cholesterol on the stone surface was significantly higher than that for patients with some calcium carbonate in this area. For all patients with functioning gallbladders, inorganic phosphorus in gallbladder bile was always higher than that in the corresponding common duct bile. In bile from functioning gallbladders, inorganic phosphorus was linearly related to pH for cholesterol stone-formers, but values for calcium carbonate stone-formers were below the regression line and not related to pH. The results show that bile from calcium carbonate stone-formers is more dilute with respect to inorganic phosphorus.
