[Agenesia of the gallbladder. Report of two new cases (author's transl)].

A propos 2 personal cases of a rare malformation, agenesia of the gallbladder, the authors reappraise the anomaly, of which the precise diagnosis is essentially surgical. They stress the frequency of associated malformation and the usefulness of operative exploration with cholangiography. There is no specific treatment for this condition. Draining the principle bile duct is warranted in case of choledocotomy.
