[Agenesis of the gallbladder (diagnostic considerations. Apropos of a case].

The authors show a case of gall-bladder agenesis, in the preoperative diagnostics of which both echotomography and T.A.C. were used. From the data of the literature, as well as from the personal experience, one can understand the preoperative diagnosis presuming gall-bladder agenesis can be placed in presence od manifestations of biliary nature added to gall-bladder nonopacity at oral cholecystography and to absence of gall-bladder at echotomography and T.A.C. The certainty diagnosis, however, can be only obtained at laparotomy with the hand exploration, with the preoperative cholangiography and eventually the selective arteriography of hepatic artery.
