Relationship between gallbladder histopathology and ability to concentrate biliary lipids and bilirubin. A study on gallstone patients with functioning gallbladder.
Biliary lipids and bilirubin were measured in hepatic and gallbladder bile obtained at routine cholecystectomy in 35 gallstone patients. The gallbladders had opacified at cholecystography and the cystic ducts were patent at operation. The histologic changes in the gallbladder wall were evaluated by an independent pathologist. Increasing abnormality of the gallbladder wall was shown to be associated with reduced gallbladder contents/hepatic bile ratio of biliary lipids and of bilirubin. The concentrating function of the human gallbladder thus appears to be impaired in proportion to the severity of histologic lesions in its wall. Taken together with earlier findings in vitro, this relationship suggests impaired absorption of electrolytes and water by the gallbladder mucosa, or diffusion of biliary constituents from the lumen of the inflamed gallbladder.
