title: Change in bile secretion in patients with calcium carbonate in their gallstones.
abstract: Common duct bile in patients with gallstones contains virtually no amylase activity. Therefore the raised levels of total CO2 concentrations found in common duct bile from patients with some calcium carbonate on the surface of their gallstones do not result from a reflux of pancreatic juice. A change in bile secretion is the likely explanation.
