[Agenesis of the gallbladder. Presentation of a case]

The authors describe one case of agenesis of the gallbladder associated with papillary stenosis, dyskinesia of the extrahepatic bile ducts, and chronic appendicitis. They devote particular attention to the composition of hepatic bile and choledochal bile, which was investigated in detail after surgical exploration of the extrahepatic bile passages, transduodenal papillosphincterotomy, and appendectomy. They conclude that this rare congenital failure of organ development, in the long run, even a slight alteration of bile composition in the hepatic and/or choledochal segment of the biliary tract (the latter somewhat serving the purpose of the missing gallbladder) may invite calculosis of the common bile duct.
