[Echography inthe study of the gallbladder wall].

In 511 patients with clinical symptoms of chronic or acute biliary disease, gallbladder area was studied by automatic equipments. In 39 patients different features of the gallbladder wall lesions were demonstrated, in some cases associated with gall stones or bile modifications. Gallbladder wall lesions were divided in three different groups, diffuse, localized or both, according to their appearance and extension. Correlations between the echographic patterns and the clinical and pathological pictures were established. The authors concluding stress the diagnostic value of cholecystosonography in detecting wall lesions such as chronic or acute cholecystitis, cholecystosis and gallbladder tumours. The indications of cholecystosonography are in such a way extended well beyond the demonstration of gallstones and bile modifications to the diagnosis of chronic and acute cholecystitis.
