[Cholelithiasis. Ultrasonography and other diagnostic methods. Usefulness, indications, and limitations].

It is reported that 12.5% of the Italian population suffer from cholecystopathy. The Authors carried out a retrospective analysis of the cases observed over an 18-month period. It was found that ultrasonography was the most appropriate screening method to reveal cholecystic pathologies and diseases of the biliary tract since it is specific and sensitive and also enables adjacent organs to be examined (liver, kidneys, aorta, pancreas, spleen).
